ABSTRACT
AIM: Pleural effusion (PE) is a common chest radiography (CXR) finding in patients with advanced cardiac disease. The pathophysiology and clinical value of PE in this setting are incompletely defined. We aimed to assess the haemodynamic correlates and prognostic impact of PE in patients with severe aortic stenosis (AS). METHODS AND RESULTS: We studied 471 patients (mean age 74 ± 10 years) with severe AS (indexed aortic valve area 0.42 ± 0.12 cm2/m2, left ventricular ejection fraction 58 ± 12%) undergoing right heart catheterization and upright CXR prior to aortic valve replacement (AVR). Two radiologist independently evaluated all CXR for the presence of bilateral PE, unilateral, or no PE, blinded to any other data. There were 49 (10%) patients with bilateral PE, 32 (7%) patients with unilateral PE, and 390 (83%) patients with no PE. Patients with bilateral PE had the highest mean right atrial pressure, mean pulmonary artery wedge pressure (mPAWP), and pulmonary vascular resistance, and had the lowest stroke volume index while those with unilateral PE had intermediate values. In the multivariate analysis, mPAWP was an independent predictor of any PE and bilateral PE. After a median (interquartile range) post-AVR follow-up of 1361 (957-1878) days mortality was highest in patients with bilateral PE (2.7 times higher than in patients without PE), whereas patients with unilateral PE had similar mortality as those without PE. CONCLUSIONS: In severe AS patients, the presence of PE, particularly bilateral PE, is a marker of a poor haemodynamic constellation. Bilateral PE is associated with a substantially increased post-AVR mortality.

BACKGROUND: There is an association between hyperthyroidism and pulmonary hypertension. However, the prevalence of pulmonary hypertension in hyperthyroidism and the underlying mechanisms are incompletely defined. METHODS: Consecutive patients with severe hyperthyroidism, mostly due to Graves disease, were included in this single-center study. Echocardiographic assessment of pulmonary hemodynamics was performed at the time of hyperthyroidism diagnosis (baseline) and after normalization of thyroid hormones (follow-up; median 11 months). In a subset of patients, right heart catheterization and noninvasive assessment of central hemodynamics was performed. RESULTS: Among all 99 patients, 31% had pulmonary hypertension at baseline. The estimated systolic pulmonary artery pressure correlated significantly with the estimated left ventricular filling pressure (E/e'). The invasively measured systolic pulmonary artery pressure correlated well with the estimated systolic pulmonary artery pressure. Cardiac output, E/e', left and right ventricular dimensions were significantly reduced from baseline to follow-up, whereas the estimated pulmonary vascular resistance did not differ. Diastolic blood pressure was significantly higher at follow-up, with no change in systolic blood pressure. The central systolic blood pressure, however, exhibited a trend for a reduction at follow-up, while the pulse wave velocity was significantly lower at follow-up. CONCLUSIONS: Approximately one-third of patients with hyperthyroidism have evidence of pulmonary hypertension. Our data suggest that an increased cardiac output and left ventricular filling pressure are the main mechanisms underlying the elevated systolic pulmonary artery pressure in hyperthyroidism, whereas there is no evidence of significant pulmonary vascular disease.

BACKGROUND: Biodegradable polymer sirolimus-eluting stents improve early stent-related clinical outcomes compared to durable polymer everolimus-eluting stents in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention. The long-term advantages of biodegradable polymer sirolimus-eluting stents after complete degradation of its polymer coating in patients with STEMI remains however uncertain. METHODS: BIOSTEMI Extended Survival (BIOSTEMI ES) was an investigator-initiated, follow-up extension study of the BIOSTEMI prospective, multicentre, single-blind, randomised superiority trial that compared biodegradable polymer sirolimus-eluting stents with durable polymer everolimus-eluting stents in patients with STEMI undergoing primary percutaneous coronary intervention at ten hospitals in Switzerland. All individuals who had provided written informed consent for participation in the BIOSTEMI trial were eligible for this follow-up study. The primary endpoint was target lesion failure, defined as a composite of cardiac death, target vessel myocardial re-infarction, or clinically indicated target lesion revascularisation, at 5 years. Superiority of biodegradable polymer sirolimus-eluting stents over durable polymer everolimus-eluting stents was declared if the Bayesian posterior probability for a rate ratio (RR) of less than 1 was greater than 0·975. Analyses were performed according to the intention-to-treat principle. The study was registered with ClinicalTrials.gov, NCT05484310. FINDINGS: Between April 26, 2016, and March 9, 2018, 1300 patients with STEMI (1622 lesions) were randomly allocated in a 1:1 ratio to treatment with biodegradable polymer sirolimus-eluting stents (649 patients, 816 lesions) or durable polymer everolimus-eluting stents (651 patients, 806 lesions). At 5 years, the primary composite endpoint of target lesion failure occurred in 50 (8%) patients treated with biodegradable polymer sirolimus-eluting stents and in 72 (11%) patients treated with durable polymer everolimus-eluting stents (difference of -3%; RR 0·70, 95% Bayesian credible interval 0·51-0·95; Bayesian posterior probability for superiority 0·988). INTERPRETATION: In patients undergoing primary percutaneous coronary intervention for STEMI, biodegradable polymer sirolimus-eluting stents were superior to durable polymer everolimus-eluting stents with respect to target lesion failure at 5 years of follow-up. The difference was driven by a numerically lower risk for ischaemia-driven target lesion revascularisation. FUNDING: Biotronik.

BACKGROUND AND OBJECTIVES: Recent data have established non-inferiority of drug-coated balloons (DCB) compared to drug-eluting stents (DES) for treatment of small-vessel coronary artery disease. Since coronary vessels in women might have anatomical and pathophysiological particularities, the safety of the DCB strategy among women compared to men needs to be assessed in more detail. METHODS: In BASKET-SMALL 2, patients with de novo lesions in coronary vessels < 3 mm and an indication for percutaneous coronary intervention were randomly allocated (1:1) to DCB vs. DES after successful lesion preparation. The primary objective of the randomized trial was to establish non-inferiority of DCB vs. DES regarding major adverse cardiac events (MACE; i.e., cardiac death, non-fatal myocardial infarction, and target vessel revascularization) after 12 months. The aim of the current sub-analysis is to evaluate whether the DCB strategy is equally safe among women and men after 12 and 36 months. RESULTS: Among 758 randomized patients, 382 were assigned to DCB (23% women) and 376 to DES (30% women). In general, women were older, had more often diabetes mellitus and renal insufficiency, and presented more often with an acute coronary syndrome, whereas men were more often smokers, had multivessel disease and a previous history of acute myocardial infarction, and received a treatment with a statin. After 3 years, the primary clinical end point was not significantly different between groups (13% women vs. 16% men, HR 0.82; 95% CI 0.52-1.30; p = 0.40). There was no interaction between sex and coronary intervention strategy regarding MACE at 36 months (10% women vs. 16% men in DCB, 16% women vs. 15% men in DES; pinteraction = 0.31). CONCLUSION: In small native coronary artery disease, there was no statistically significant effect of sex on the difference between DCB and DES regarding MACE up to 36 months.

ABSTRACT
BACKGROUND: Whether ultrathin-strut stents are particularly beneficial for lesions requiring implantation of more than 1 stent is unknown. METHODS: In a post-hoc lesion-level analysis of 2 randomized trials comparing ultrathin-strut biodegradable polymer Sirolimus-eluting stents (BP-SES) vs thin-strut durable polymer Everolimus-eluting stents (DP-EES), lesions were stratified into multistent lesions (MSL) vs single-stent lesions (SSL). The primary endpoint was target lesion failure (TLF), a composite of lesion-related unclear/cardiac death, myocardial infarction (MI), or revascularization, at 24 months. RESULTS: Among 5328 lesions in 3397 patients, 1492 (28%) were MSL (722 with BP-SES, 770 with DP-EES). At 2 years, TLF occurred in 63 lesions (8.9%) treated with BP-SES and 60 lesions (7.9%) treated with DP-EES in the MSL-group (subdistibution hazard ratio [SHR], 1.13; 95% CI, 0.77-1.64; P = .53), and in 121 (6.4%) and 136 (7.4%) lesions treated with BP-SES and DP-EES respectively (SHR, 0.86; 95% CI, 0.62-1.18; P = .35) in the SSL-group (P for interaction = .241). While the rates of lesion-related MI or revascularization were significantly lower in SSL treated with BP-SES as compared to DP-EES (3.5% vs 5.2%; SHR, 0.67; 95% CI 0.46-0.97; P = .036), no significant difference was observed in MSL (7.1% vs 5.4%; SHR, 1.31; 95% CI 0.85-2.03; P = .216) with significant interaction between groups (P for interaction = .014). CONCLUSIONS: Rates of TLF are similar between ultrathin-strut BP-SES and thin-strut DP-EES in MSL and SSL. The use of ultrathin-strut BP-SES vs thin-strut DP-EES did not prove to be particularly beneficial for the treatment of multistent lesions. TRIAL REGISTRATION: Post-hoc analysis from the BIOSCIENCE (NCT01443104) and BIOSTEMI (NCT02579031) trials.

BACKGROUND: A decade ago, the iopromide-paclitaxel coated balloon (iPCB) was added to the cardiologist's toolbox to initially treat in-stent restenosis followed by the treatment of de novo coronary lesions. In the meantime, DES technologies have been substantially improved to address in-stent restenosis and thrombosis, and shortened anti-platelet therapy. Recently, sirolimus-coated balloon catheters (SCB) have emerged to provide an alternative drug to combat restenosis. METHODS: The objective of this study is to determine the safety and efficacy of a novel crystalline sirolimus-coated balloon (cSCB) technology in an unselective, international, large-scale patient population. Percutaneous coronary interventions of native stenosis, in-stent stenosis, and chronic total occlusions with the SCB in patients with stable coronary artery disease or acute coronary syndrome were included. The primary outcome variable is the target lesion failure (TLF) rate at 12 months, defined as the composite rate of target vessel myocardial infarction (TV-MI), cardiac death or ischemia-driven target lesion revascularization (TLR). The secondary outcome variables include TLF at 24 months, ischemia driven TLR at 12 and 24 months and all-cause death, cardiac death at 12 and 24 months. DISCUSSION: Since there is a wealth of patient-based all-comers data for iPCB available for this study, a propensity-score matched analysis is planned to compare cSCB and iPCB for the treatment of de novo and different types of ISR. In addition, pre-specified analyses in challenging lesion subsets such as chronic total occlusions will provide evidence whether the two balloon coating technologies differ in their clinical benefit for the patient.

BACKGROUND: Gender-specific data addressing percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) in female patients are scarce and based on small sample size studies. AIMS: We aimed to analyze gender-differences regarding in-hospital clinical outcomes after CTO-PCI. METHODS: Data from 35,449 patients enrolled in the prospective European Registry of CTOs were analyzed. The primary outcome was the comparison of procedural success rate in the two cohorts (women vs. men), defined as a final residual stenosis less than 20%, with Thrombolysis In Myocardial Infarction grade flow = 3. In-hospital major adverse cardiac and cerebrovascular events (MACCEs) and procedural complications were deemed secondary outcomes. RESULTS: Women represented 15.2% of the entire study population. They were older and more likely to have hypertension, diabetes, and renal failure, with an overall lower J-CTO score. Women showed a higher procedural success rate (adjusted OR [aOR] = 1.115, confidence interval [CI]: 1.011-1.230, p = 0.030). Apart from previous myocardial infarction and surgical revascularization, no other significant gender differences were found among predictors of procedural success. Antegrade approach with true-to-true lumen techniques was more commonly used than retrograde approach in females. No gender differences were found regarding in-hospital MACCEs (0.9% vs. 0.9%, p = 0.766), although a higher rate of procedural complications was observed in women, such as coronary perforation (3.7% vs. 2.9%, p < 0.001) and vascular complications (1.0% vs. 0.6%, p < 0.001). CONCLUSIONS: Women are understudied in contemporary CTO-PCI practice. Female sex is associated with higher procedural success after CTO-PCI, yet no sex differences were found in terms of in-hospital MACCEs. Female sex was associated with a higher rate of procedural complications.

BACKGROUND: We evaluated the outcome of PCI of de novo stenosis with drug-coated balloons (DCB) versus drug-eluting stents (DES) in patients with insulin-treated diabetes mellitus (ITDM) versus non-insulin-treated diabetes mellitus (NITDM). METHODS: Patients were randomized in the BASKET-SMALL 2 trial to DCB or DES and followed over 3 years for MACE (cardiac death, non-fatal myocardial infarction [MI], and target vessel revascularization [TVR]). Outcome in the diabetic subgroup (n = 252) was analyzed with respect to ITDM or NITDM. RESULTS: In NITDM patients (n = 157), rates of MACE (16.7% vs. 21.9%, hazard ratio [HR] 0.68, 95% confidence interval [CI] 0.29-1.58, p = 0.37), death, non-fatal MI, and TVR (8.4% vs. 14.5%, HR 0.30, 95% CI 0.09-1.03, p = 0.057) were similar between DCB and DES. In ITDM patients (n = 95), rates of MACE (DCB 23.4% vs. DES 22.7%, HR 1.12, 95% CI 0.46-2.74, p = 0.81), death, non-fatal MI, and TVR (10.1% vs. 15.7%, HR 0.64, 95% CI 0.18-2.27, p = 0.49) were similar between DCB and DES. TVR was significantly lower with DCB versus DES in all diabetic patients (HR 0.41, 95% CI 0.18-0.95, p = 0.038). CONCLUSIONS: DCB compared to DES for treatment of de novo coronary lesions in diabetic patients was associated with similar rates of MACE and numerically lower need for TVR both for ITDM and NITDM patients.
ABSTRACT
BACKGROUND: Ultrathin-strut biodegradable polymer sirolimus-eluting stents (BP-SES) are superior to thin-strut durable polymer everolimus-eluting stents (DP-EES) with respect to target lesion failure (TLF) at 2 years among patients with ST-segment elevation myocardial infarction (STEMI). We sought to determine the impact of primary percutaneous coronary intervention (pPCI) complexity on long-term clinical outcomes with BP-SES versus DP-EES in STEMI patients. METHODS: We performed a post hoc subgroup analysis from the BIOSTEMI (NCT02579031) randomized trial, which included individual data from 407 STEMI patients enrolled in the BIOSCIENCE trial (NCT01443104). STEMI patients were randomly assigned to treatment with ultrathin-strut BP-SES or thin-strut DP-EES, and further categorized into those undergoing complex versus noncomplex pPCI. Complex pPCI was defined by the presence of ≥1 of the following criteria: 3 vessel treatment, ≥3 stents implanted, ≥3 lesions treated, bifurcation lesion with ≥2 stents implanted, total stent length ≥60 mm, and/or chronic total occlusion treatment. The primary endpoint was TLF, a composite of cardiac death, target-vessel myocardial reinfarction, or clinically indicated target lesion revascularization, within 2 years. RESULTS: Among a total of 1707 STEMI patients, 421 (24.7%) underwent complex pPCI. Baseline characteristics were similar between groups. At 2 years, TLF occurred in 14 patients (7.1%) treated with BP-SES and 25 patients (11.6%) treated with DP-EES (hazard ratio [HR]: 0.62; 95% confidence interval [CI]: 0.32-1.19; p = 0.15) in the complex pPCI group, and in 28 patients (4.4%) treated with BP-SES and 49 patients (8.2%) treated with DP-EES (HR: 0.54; 95% CI: 0.34-0.86; p = 0.008; p for interaction = 0.74) in the noncomplex pPCI group. Individual TLF components and stent thrombosis rates did not significantly differ between groups. CONCLUSION: In a post hoc subgroup analysis from the BIOSTEMI randomized trial, ultrathin-strut BP-SES were superior to thin-strut DP-EES with respect to TLF at 2 years among STEMI patients undergoing both complex and noncomplex pPCI.

BACKGROUND: In aortic stenosis (AS), estimated glomerular filtration rate (eGFR) is an important prognostic marker but its haemodynamic determinants are unknown. We investigated the correlation between eGFR and invasive haemodynamics and long-term mortality in AS patients undergoing aortic valve replacement (AVR). METHODS: We studied 503 patients [median (interquartile range) age 76 (69-81) years] with AS [indexed aortic valve area .42 (.33-.49) cm2 /m2 ] undergoing cardiac catheterization prior to surgical (72%) or transcatheter (28%) AVR. Serum creatinine was measured on the day before cardiac catheterization for eGFR calculation (CKD-EPI formula). RESULTS: The median eGFR was 67 (53-82) mL/min/1.73 m2 . There were statistically significant correlations between eGFR and mean right atrial pressure (r = -.13; p = .004), mean pulmonary artery pressure (mPAP; r = -.25; p < .001), mean pulmonary artery wedge pressure (r = -.19; p < .001), pulmonary vascular resistance (r = -.21; p < .001), stroke volume index (r = .16; p < .001), extent of coronary artery disease, and mean transvalvular gradient but not indexed aortic valve area. In multivariate linear regression, higher age, lower haemoglobin, lower mean transvalvular gradient (i.e. lower flow), lower diastolic blood pressure, and higher mPAP were independent predictors of lower eGFR. After a median post-AVR follow-up of 1348 (948-1885) days mortality was more than two-fold higher in patients in the first eGFR quartile compared to those in the other three quartiles [hazard ratio 2.18 (95% confidence interval 1.21-3.94); p = .01]. CONCLUSION: In patients with AS, low eGFR is a marker of an unfavourable haemodynamic constellation as well as important co-morbidities. This may in part explain the association between low eGFR and increased post-AVR mortality.

AIMS: Blood pressure (BP) targets in patients with aortic stenosis (AS) are controversial. This study sought to describe the haemodynamic profile and the clinical outcome of severe AS patients with low versus high central meaarterial pressure (MAP). METHODS AND RESULTS: Patients with severe AS (n = 477) underwent right and left heart catheterization prior to aortic valve replacement (AVR). The population was divided into MAP quartiles. The mean systolic BP, diastolic BP, and MAP in the entire population were 149 ± 25, 68 ± 11, and 98 ± 14 mmHg. Patients in the lowest MAP quartile had the lowest left ventricular ejection fraction (LVEF), systemic vascular resistance, and valvulo-arterial impedance, whereas there were no significant differences in mean right atrial pressure, mean pulmonary artery wedge pressure, pulmonary vascular resistance, and stroke volume index across MAP quartiles. However, left ventricular stroke work index (LVSWI) was lowest in patients in the lowest and highest in those in the highest MAP quartile. After a median (interquartile range) post-AVR follow-up of 3.7 (2.6-5.2) years, mortality was highest in patients in the lowest MAP quartile [hazard ratio 3.08 (95% confidence interval 1.21-7.83); P = 0.02 for lowest versus highest quartile]. In the multivariate analysis, lower MAP [hazard ratio 0.78 (95% confidence interval 0.62-0.99) per 10 mmHg increase; P = 0.04], higher mean right atrial pressure and lower LVEF were independent predictors of death. CONCLUSIONS: In severe AS patients, lower MAP reflects lower systemic vascular resistance and valvulo-arterial impedance, which may help to preserve stroke volume and filling pressures despite reduced left ventricular performance, and lower MAP is a predictor of higher long-term post-AVR mortality.

Background: The relationship between chest radiograph (CXR) findings of pulmonary congestion and invasive hemodynamics and clinical outcomes in patients with cardiac diseases is unclear. We assessed the correlation between a CXR-based congestion score (RxCS) and the mean pulmonary artery wedge pressure (mPAWP) and the prognostic impact of RxCS and mPAWP in severe aortic stenosis (AS). Methods: In 471 patients with severe AS undergoing right heart catheterization and upright CXR, the RxCS was calculated (6 items, maximum score: 10 points) independently by 2 radiologists (average value taken) blinded to clinical data. Congestion was defined as an RxCS > 1. Four patterns were defined based on the presence or absence of congestion (C+ or C-) and elevated (> 15 mm Hg) or normal mPAWP (P+ or P-). Results: The median (interquartile range) RxCS was 1 (0-2). Patients with an RxCS > 1 (n = 207) had a higher mean right atrial pressure, mean pulmonary artery pressure, mPAWP, and pulmonary vascular resistance than patients with an RxCS ≤ 1 (n = 264). However, the correlation between the RxCS and the mPAWP was moderate only (r = 0.45). Patients with a C+/P+ pattern had the worst hemodynamics, whereas C-/P- patients had the most favourable constellation. After a median post-valve replacement follow-up of 1361 days, mortality was higher in patients with RxCs > 1 vs ≤ 1 as well as mPAWP > 15 mm Hg vs ≤15 mm Hg. Mortality was highest in C+/P+ patients and lowest in C-/P- patients, whereas it was intermediate in C-/P+ and C+/P- patients. Conclusions: In AS patients, RxCS and mPAWP have a significant but moderate correlation. Both RxCS and mPAWP provide prognostic information.
Contexte: Des zones floues persistent quant au lien entre les signes de congestion pulmonaire à la radiographie thoracique, les examens hémodynamiques invasifs et les résultats cliniques chez les patients atteints de maladies cardiaques. Nous avons donc évalué, d'une part, la corrélation entre le score radiologique de congestion pulmonaire et la pression capillaire pulmonaire moyenne et, d'autre part, la valeur pronostique du score radiologique de congestion pulmonaire et de la pression capillaire pulmonaire moyenne dans les cas de sténose aortique sévère. Méthodologie: Chez 471 patients atteints d'une sténose aortique sévère soumis à un cathétérisme du cÅur droit et à une radiographie thoracique en position debout, un score radiologique de congestion pulmonaire a été calculé (6 items, score maximal de 10 points) de façon indépendante par deux radiologistes (la valeur retenue étant la moyenne) qui ne connaissaient pas les données cliniques des patients. La congestion correspondait à un score radiologique de congestion pulmonaire > 1. Quatre types ont été définis en fonction de la présence ou de l'absence de congestion (C+ ou C) et d'une valeur de pression capillaire pulmonaire moyenne élevée (>15 mmHg) ou normale (P+ ou P). Résultats: La médiane (écart interquartile) du score radiologique de congestion a été de 1 (0-2). Les patients dont le score radiologique de congestion était > 1 (n = 207) présentaient des valeurs moyennes plus élevées pour la pression auriculaire droite, la pression artérielle pulmonaire, la pression capillaire pulmonaire et la résistance vasculaire pulmonaire que les patients dont le score radiologique de congestion était ≤ 1 (n = 264). Cependant, la corrélation entre le score radiologique de congestion et la pression capillaire pulmonaire moyenne n'était que modérée (r = 0,45). Les patients de type C+/P+ avaient le profil hémodynamique le plus défavorable, tandis que les patients de type C/P avaient le profil le plus favorable. À l'issue d'un suivi médian de 1361 jours après un remplacement valvulaire, la mortalité était plus élevée chez les patients dont le score radiologique de congestion était > 1 vs un score ≤ 1, de même que chez les patients dont la pression capillaire pulmonaire moyenne était > 15 mmHg vs une valeur ≤ 15 mmHg. La mortalité la plus élevée a été observée chez les patients de type C+/P+, et la plus faible, chez les patients de type C/P, tandis qu'elle était intermédiaire chez les patients de types C/P+ et C+/P. Conclusions: Chez les patients atteints d'une sténose aortique, on constate une corrélation significative mais modérée entre le score radiologique de congestion pulmonaire et la pression capillaire pulmonaire moyenne. Ces paramètres revêtent tous deux une valeur pronostique.
ABSTRACT
BACKGROUND: Considering the global burden of cardiovascular disease, we analysed trends in interventional coronary and structural procedures over the past 16 years (2005-2021), using continuous data from the Swiss national registry. METHODS: Based on a standardised questionnaire, data on coronary and structural interventions in Switzerland were assessed by the Working Group Interventional Cardiology of the Swiss Society of Cardiology (SSC). Here, we analysed the trend of annually performed interventions from 2005 to 2021 in Switzerland and the impact of the COVID-19 pandemic. RESULTS: We observed a constant increase in the total number of cases (including coronary angiographies (CA) and percutaneous coronary interventions (PCI)) from 36,436 cases in 2005 to 56,555 cases in 2021 (+55%). With 18 cases in 2007, TAVI procedures have increased to 2004 cases in 2021. During the early phase of the COVID-19 pandemic in 2020, a slight decrease in CAs and PCIs of 9.15% was observed. In contrast, we did not observe an impact of the COVID-19 pandemic on the number of no TAVI procedures. Most importantly, all cause in-hospital mortality for coronary interventions before and during the peak of the COVID-19 pandemic was comparable (1.4% vs. 1.3%). CONCLUSION: Over a 16-year period, we observed an upward trend in diagnostic and therapeutic procedures for coronary as well as structural heart disease, with only a small short-term impact of the COVID-19 pandemic on interventions and a similar procedure-related in-hospital-mortality in Switzerland.
ABSTRACT
BACKGROUND: Patients at high-bleeding risk (HBR) undergoing percutaneous coronary intervention represent a challenging patient population. The use of drug-coated balloon (DCB) allows shorter duration of dual antiplatelet therapy compared with drug-eluting stents (DES) and reduces thrombotic risk due to the absence of a permanent implant. The present analysis aimed to investigate if the effect of DCB versus DES differed between patients with and without HBR treated with percutaneous coronary intervention in small coronary arteries. METHODS: This prespecified subgroup analysis of a multicenter, randomized, noninferiority trial included 758 patients with de novo lesions in coronary vessels <3 mm and an indication for percutaneous coronary intervention, randomized to DCB (n=382) or second-generation DES (n=376). Patients were followed over 3 years for major adverse cardiac events. RESULTS: Of the 758 patients randomized, 155 (20%) had HBR; these patients had higher mortality at 3 years (hazard ratio [95% CI], 3.09 [1.78-5.36]; P<0.001). Rates of major bleeding events were overall low but tended to be lower after DCB versus DES (1.6% versus 3.7%; P=0.064), were similar in patients with HBR (4.5% versus 3.4%) but less frequent in DCB-versus DES-treated patients without HBR (0.9% versus 3.8%). There was no difference in major adverse cardiac events between DCB and DES regardless of bleeding risk (HBR, hazard ratio: 1.16 [0.51-2.62]; P=0.719 versus non-HBR, 0.96 [0.62-1.49]; P=0.863). CONCLUSIONS: DCBs were similarly safe and effective as current-generation DES in the treatment of coronary arteries <3 mm, regardless of bleeding risk.

BACKGROUND: Data on the safety and efficacy of drug-coated balloon (DCB) compared to drug-eluting stent (DES) in patients with chronic kidney disease (CKD) are scarce, particularly at long term. This pre-specified analysis aimed to investigate the 3-year efficacy and safety of DCB versus DES for small coronary artery disease (< 3 mm) according to renal function at baseline. METHODS: BASKET-SMALL-2 was a large multi-center, randomized, controlled trial that tested the efficacy and safety of DCBs (n = 382) against DESs (n = 376) in small vessel disease. CKD was defined as eGFR < 60 ml/min/1.73m2. The primary endpoint was the composite of cardiac death, non-fatal myocardial infarction, and target vessel revascularization (MACE) during 3 years. RESULTS: A total of 174/758 (23%) patients had CKD, out of which 91 were randomized to DCB and 83 to DES implantation. The primary efficacy outcome during 3 years was similar in both, DCB and DES patients (HR 0.98; 95%-CI 0.67-1.44; p = 0.937) and patients with and without CKD (HR 1.18; 95%-CI 0.76-1.83; p = 0.462), respectively. Rates of cardiac death and all-cause death were significantly higher among patients with CKD but not affected by treatment with DCB or DES. Major bleeding events were lower in the DCB when compared to the DES group (12 vs. 3, HR 0.26; 95%-CI 0.07-0.92; p = 0.037) and not influenced by presence of CKD. CONCLUSIONS: The long-term efficacy and safety of DCB was similar in patients with and without CKD. The use of DCB was associated with significantly fewer major bleeding events (NCT01574534).

BACKGROUND: Drug-coated balloons (DCBs) are an established treatment strategy for coronary artery disease. Randomized data on the application of DCBs in patients with an acute coronary syndrome (ACS) are limited. We evaluated the impact of clinical presentation (ACS versus chronic coronary syndrome) on clinical outcomes in patients undergoing DCB or drug-eluting stent (DES) treatment in a prespecified analysis of the BASKET-SMALL 2 trial (Basel Kosten Effektivitäts Trial-Drug-Coated Balloons Versus Drug-Eluting Stents in Small Vessel Interventions). METHODS: BASKET-SMALL 2 randomized 758 patients with small vessel coronary artery disease to DCB or DES treatment and followed them for 3 years regarding major adverse cardiac events (cardiac death, nonfatal myocardial infarction, and target vessel revascularization). RESULTS: Among 758 patients, 214 patients (28.2%) presented with an ACS (15 patients [7%], ST-segment-elevation myocardial infarction; 109 patients [50.9%], non-ST-segment-elevation myocardial infarction; 90 patients [42.1%], unstable angina pectoris). At 1-year follow-up, there was no significant difference in the incidence of the primary end point by randomized treatment in patients with ACS (hazard ratio, 0.50 [95% CI, 0.19-1.26] for DCB versus DES) or chronic coronary syndrome (hazard ratio, 1.29 [95% CI, 0.67-2.47] for DCB versus DES). There was no significant interaction between clinical presentation and treatment effect (P for interaction, 0.088). For cardiac death (P for interaction, 0.049) and nonfatal myocardial infarction (P for interaction, 0.010), a significant interaction between clinical presentation and treatment was seen at 1 year with lower rates of these secondary end points in patients with ACS treated by DCB. At 3 years, there were similar major adverse cardiac event rates throughout groups without significant interaction between clinical presentation and treatment (P for interaction, 0.301). All-cause mortality was higher in ACS compared with chronic coronary syndrome; however, there was no difference between DCB and DES irrespective of clinical presentation. CONCLUSIONS: In this subgroup analysis of the BASKET-SMALL 2 trial, there was no interaction between indication for percutaneous coronary intervention (acute versus chronic coronary syndrome) and treatment effect of DCB versus DES in patients with small vessel coronary artery disease.

BACKGROUND: Thin-strut biodegradable polymer sirolimus-eluting stents (BP-SES) have been shown to reduce target lesion failure (TLF) at one-year follow-up compared with durable polymer everolimus-eluting stents (DP-EES) among patients with acute coronary syndrome (ACS). The long-term clinical benefits of thin-strut BP-SES over DP-EES in ACS patients after complete degradation of the polymer coating remain uncertain. METHODS: We performed a post-hoc subgroup analysis of ACS patients included into the BIOSCIENCE randomized trial (NCT01443104). The primary endpoint was target lesion failure (TLF), a composite of cardiac death, target-vessel myocardial infarction or clinically indicated target lesion revascularization, at 5 years. RESULTS: Among 2119 patients enrolled between March 2012 and May 2013, 1131 (53%) presented with ACS. The 5-year cumulative incidence of TLF was significantly lower in patients with ACS compared to chronic coronary syndrome [16.5% vs. 22.9%; rate ratio (RR), 0.69; 95% confidence interval (CI), 0.57-0.85; p < 0.001]. At 5 years, TLF occurred similarly in ACS patients treated with BP-SES and DP-EES (16.9% vs. 16.0%; RR, 1.04; 95% CI, 0.78-1.41; p = 0.78). The individual components of the primary endpoint did not differ between ACS patients treated with BP-SES or DP-EES at 5 years. Overall, there was no interaction between clinical presentation and treatment effect. CONCLUSIONS: In a subgroup analysis of the BIOSCIENCE trial, we found no difference in long-term outcomes between ACS patients treated with BP-SES or DP-EES at 5 years.

AIMS OF THE STUDY: Spontaneous coronary artery dissection (SCAD) is an increasingly diagnosed cause of acute myocardial infarction. However, there is still a limited number of larger cohorts with long-term follow-up. We report on the largest Swiss single-centre cohort to date, with follow-up of up to 22 years. METHODS: We prospectively collected SCAD cases from June 1998 until December 2020. A strategy of systematic follow-up angiography was applied. Information on long-term follow-up was collected up to the end of 2020. Major cardiovascular events (MACE) were defined as all-cause death, non-fatal MI, and non-fatal cardiac arrest. RESULTS: We identified 105 SCAD patients (mean age 53 ± 11 years, 98 female, 5 peripartum). Presentation was myocardial infarction in all patients. In 102 patients, there was one contiguous dissection. Three patients had two (n = 2) or three (n = 1) non-contiguous dissections. In the majority of patients (n = 97), the primary treatment approach was conservative (dual antiplatelet therapy for 12 months in 90% of patients, statins in 91%). Seven patients were treated with percutaneous coronary intervention (PCI) and one patient underwent bypass surgery. Elective follow-up angiograms were performed in 73 asymptomatic patients after a median follow-up of 6.0 months (interquartile range [IQR] 5.5-6.5). These showed healing of the dissection (n = 65) or a good result after PCI (n = 5) in 70 patients. Three patients had a persistent dissection but conservative treatment was continued. After a median follow-up of 7.5 years (IQR 3.6-12.5) (longest follow-up: 22.5 years) there were 15 MACE. Five MACE occurred within 30 days of the index event: death following catastrophic peripartum left main SCAD (n = 1), out-of-hospital cardiac arrest with successful resuscitation 16 days after SCAD (n = 1), ST-segment elevation myocardial infarction due to occlusion of the dissected artery 10 hours after the index angiogram with subsequent PCI (n = 1), SCAD of a second vessel 8 days after the index SCAD (n = 1), and non-ST-segment elevation myocardial infarction with persistent, multisite SCAD 10 days after the index event (n = 1). There were 10 late MACE, including myocardial infarction and recurrent SCAD (different vessel/lesion) a median of 7.6 years (IQR 3.9-9.6) after the index event in eight patients and death with unclear cause in two patients. CONCLUSION: This SCAD series highlights its highly variable clinical course during the acute phase and in the long term. Although most SCAD patients can be treated conservatively with subsequent healing of the dissection and good clinical outcome, there are also patients with dramatic acute presentation or MACE several years after the initial presentation.

(1) Background: Pulmonary hypertension after aortic valve replacement (AVR; post-AVR PH) carries a poor prognosis. We assessed the pre-AVR hemodynamic characteristics of patients with versus without post-AVR PH. (2) Methods: We studied 205 patients (mean age 75 ± 10 years) with severe AS (indexed aortic valve area 0.42 ± 0.12 cm2/m2, left ventricular ejection fraction 58 ± 11%) undergoing right heart catheterization (RHC) prior to surgical (70%) or transcatheter (30%) AVR. Echocardiography to assess post-AVR PH, defined as estimated systolic pulmonary artery pressure > 45 mmHg, was performed after a median follow-up of 15 months. (3) Results: There were 83/205 (40%) patients with pre-AVR PH (defined as mean pulmonary artery pressure (mPAP) ≥ 25 mmHg by RHC), and 24/205 patients (12%) had post-AVR PH (by echocardiography). Among the patients with post-AVR PH, 21/24 (88%) had already had pre-AVR PH. Despite similar indexed aortic valve area, patients with post-AVR PH had higher mPAP, mean pulmonary artery wedge pressure (mPAWP) and pulmonary vascular resistance (PVR), and lower pulmonary artery capacitance (PAC) than patients without. (4) Conclusions: Patients presenting with PH roughly one year post-AVR already had worse hemodynamic profiles in the pre-AVR RHC compared to those without, being characterized by higher mPAP, mPAWP, and PVR, and lower PAC despite similar AS severity.
ABSTRACT
OBJECTIVES: The study sought to evaluate the impact of diabetes mellitus on 3-year clinical outcome in patients undergoing drug-coated balloon (DCB) or drug-eluting stent (DES) treatment for de novo lesions. BACKGROUND: For treatment of de novo coronary small vessel disease, DCBs are noninferior to DES. METHODS: In this prespecified analysis of a multicenter, randomized, noninferiority trial, including 758 patients with de novo lesions in coronary vessels <3 mm who were randomized 1:1 to DCB or DES and followed over 3 years for major adverse cardiac events (MACE) (cardiac death, nonfatal myocardial infarction [MI], and target vessel revascularization [TVR]), outcome was analyzed regarding the presence or absence of diabetes mellitus. RESULTS: In nondiabetic patients (n = 506), rates of MACE (DCB 13.0% vs DES 11.5%; hazard ratio [HR]: 1.24; 95% confidence interval [CI]: 0.73-2.09; P = 0.43), cardiac death (2.8% vs 2.9%; HR: 0.97; 95% CI: 0.32-2.92; P = 0.96), nonfatal MI (5.1% vs 4.8%; HR: 1.00; 95% CI: 0.44-2.28; P = 0.99), and TVR (8.8% vs 6.1%; HR: 1.64; 95% CI: 0.83-3.25; P = 0.16) were similar. In diabetic patients (n = 252), rates of MACE (19.3% vs 22.2%; HR: 0.82; 95% CI: 0.45-1.48; P = 0.51), cardiac death (8.8% vs 5.9%; HR: 2.01; 95% CI: 0.76-5.31; P = 0.16), and nonfatal MI (7.1% vs 9.8%; HR: 0.55; 95% CI: 0.21-1.49; P = 0.24) were similar in DCB and DES. TVR was significantly lower with DCBs vs DES (9.1% vs 15.0%; HR: 0.40; 95% CI: 0.17-0.94; P = 0.036; P = 0.011 for interaction). CONCLUSIONS: The rates of MACE are similar in DCBs and DES in de novo coronary lesions of diabetic and nondiabetic patients. In diabetic patients, need for TVR was significantly lower with DCB versus DES.
