RESUMO
BACKGROUND: About half of patients with severe aortic stenosis present with concomitant coronary artery disease. The optimal timing of percutaneous coronary intervention (PCI) and transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis and concomitant coronary artery disease remains unknown. STUDY DESIGN: The TAVI PCI trial is a prospective, international, multicenter, randomized, two-arm, open-label study planning to enroll a total of 986 patients. It is designed to investigate whether the strategy "angiography-guided complete revascularization after (within 1-45 days) TAVI" is non-inferior to the strategy "angiography-guided complete revascularization before (within 1-45 days) TAVI" using the Edwards SAPIEN 3 or 3 Ultra Transcatheter Heart Valve™ in patients with severe aortic stenosis and concomitant coronary artery disease. Patients are randomized in a 1:1 ratio to one of the two treatment strategies. The primary end point is a composite of all-cause death, non-fatal myocardial infarction, ischemia-driven revascularization, rehospitalization (valve- or procedure-related including heart failure), or life-threatening/disabling or major bleeding at 1 year. CONCLUSIONS: The TAVI PCI trial tests the hypothesis that the strategy "PCI after TAVI" is non-inferior to the strategy "PCI before TAVI" in patients with severe aortic stenosis and concomitant coronary artery disease.
RESUMO
AIMS: We aimed to evaluate transcatheter mitral valve implantation (TMVI) using predominantly balloon-expandable transcatheter heart valves (THV) in patients with a landing zone for a percutaneously delivered prosthesis. BACKGROUND: Patients with a degenerated mitral valve bioprosthesis, annuloplasty ring, and mitral annulus calcification (MAC) considered at high surgical risk currently represent a treatment challenge. TMVI is an alternative treatment option. METHODS: Retrospective analysis of patients with symptomatic degenerated mitral valve bioprosthesis, or annuloplasty ring, and MAC treated with TMVI between November 2011 and April 2021. Endpoints were defined according to Mitral Valve Academic Research Consortium (MVARC) criteria and included device and procedure success at 30 days as well as mortality at 30 days and 1 year after the procedure. RESULTS: A total of 77 patients underwent TMVI (valve in valve [ViV = 56], valve in ring [ViR = 11], and valve in MAC [ViMAC = 10]). There was a trend toward higher technical success (all = 93.5%, ViV = 96.4%, ViR = 90.9%, ViMAC = 80%, p = 0.06) and lower 30-day (all = 11.7%, ViV = 10.7%, ViR = 9.1%, ViMAC = 20%, p = 0.49) and 1-year mortality (all = 26%, ViV = 23.2%, ViR = 27.3%, ViMAC= 40%, p = 0.36) after ViV and ViR compared to ViMAC. CONCLUSION: TMVI represents a reasonable treatment option in selected patients with MAC or who are poor candidates for redo mitral valve surgery. Technical success and survival up to 1 year were not significantly dependent on the subgroup in which TMVI was performed.
RESUMO
BACKGROUND: Lesion preparation with a cutting (CB) or scoring balloon (SB) is often used in patients with in-stent restenosis (ISR). However, there are no comparative studies. METHODS: We analyzed 81 patients (CB group: n = 38; SB group: n = 43) who had a calcified ISR from November 2019 to September 2021. The primary endpoint was strategy success (less than 20% residual stenosis); the secondary endpoints were major adverse cardiovascular events during the 1-year follow-up. Quantitative coronary angiography was performed to evaluate the strategy success. RESULTS: The patients in the CB group were more likely to have a severe calcified ISR (P = .001) and multiple stent layers (P = .001). A total of 64 patients (79.0%) reached the primary endpoint. Residual stenosis greater than 20% was more common in the CB group (39.5% vs 4.7%; P = .001). In the multivariate analysis, an effect of the intervention group on the achievement of the primary endpoint could be excluded (estimate 1.06; standard error 1.07; P = .322). The time interval of stent implantation prior to CB/SB (P = .007) and severe calcified ISR (P = .009) had a negative impact on reaching the primary endpoint. During the follow-up, there were no differences in rates of cardiac death (CB 2.5% vs. SB 1.2%; P = .598), acute myocardial infarction (CB 0% vs. SB 4.9%; P = .119), and target lesion failure (CB 3.7% vs SB 12.3%; P = .074). CONCLUSIONS: In our cohort, multivariate analysis showed that lesion preparation with CB or SB must be considered equivalent in terms of angiographic results. Factors like severe calcified ISR and the time interval of prior stent implantation negatively influenced the angiographic outcome.
RESUMO
INTRODUCTION AND OBJECTIVES: Multivessel percutaneous coronary intervention (MV-PCI) is recommended in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease (CAD) without cardiogenic shock. The present network meta-analysis investigated the optimal timing of MV-PCI in this context. METHODS: We pooled the aggregated data from randomized trials investigating stable STEMI patients with multivessel CAD treated with a strategy of either MV-PCI or culprit vessel-only PCI. The primary outcome was all-cause death. The main secondary outcomes were cardiovascular death, myocardial infarction, and unplanned ischemia-driven revascularization. RESULTS: Among 11 trials, a total of 10 507 patients were randomly assigned to MV-PCI (same sitting, n=1683; staged during the index hospitalization, n=3460; staged during a subsequent hospitalization within 45 days, n=3275) or to culprit vessel-only PCI (n=2089). The median follow-up was 18.6 months. In comparison with culprit vessel-only PCI, MV-PCI staged during the index hospitalization significantly reduced all-cause death (risk ratio, 0.73; 95%CI, 0.56-0.92; P=.008) and ranked as possibly the best treatment option for this outcome compared with all other strategies. In comparison with culprit vessel-only PCI, a MV-PCI reduced cardiovascular mortality without differences dependent on the timing of revascularization. MV-PCI within the index hospitalization, either in a single procedure or staged, significantly reduced myocardial infarction and unplanned ischemia-driven revascularization, with no significant difference between each other. CONCLUSIONS: In patients with STEMI and multivessel CAD without cardiogenic shock, multivessel PCI within the index hospitalization, either in a single procedure or staged, represents the safest and most efficacious approach. The different timings of multivessel PCI did not result in any significant differences in all-cause death. This study is registered at PROSPERO (CRD42023457794).
RESUMO
Background: The interplay between the right ventricle and the pulmonary artery, known as right ventricular to pulmonary artery (RV-PA) coupling, is crucial for assessing right ventricular systolic function against the afterload from the pulmonary circulation. Pulmonary artery pressure levels are ideally measured by right heart catheterization. Yet, echocardiography represents the most utilized method for evaluating pulmonary artery pressure levels, albeit with limitations in accuracy. This study therefore aims to evaluate the prognostic significance of right ventricular to pulmonary artery (RV-PA) coupling expressed as tricuspid annular plane systolic excursion (TAPSE) related to systolic pulmonary artery pressure (sPAP) levels measured by right heart catheterization (TAPSE/sPAPinvasive) or estimated by transthoracic echocardiography (TAPSE/sPAPechocardiography) in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). Methods: Using data from a bicentric registry, this study compares TAPSE/sPAPinvasive vs. TAPSE/sPAPechocardiography in predicting 1-year all-cause mortality after TAVR. Results: Among 333 patients with complete echocardiography and right heart catheterization data obtained before TAVR, their mean age was 79.8 ± 6.74 years, 39.6% were female, and general 1-year survival was 89.8%. sPAPinvasive and sPAPechocardiography showed only moderate correlation (Pearson correlation coefficient R: 0.53, p value: <0.0001). TAPSE/sPAPinvasive was superior to TAPSE/sPAPechocardiography in predicting 1-year all-cause mortality after TAVR (area under the curve: 0.662 vs. 0.569, p value: 0.025). Patients with reduced TAPSE/sPAPinvasive levels (< 0.365 mm/mmHg) evidenced significantly lower 1-year survival rates than patients with preserved TAPSE/sPAPinvasive levels (81.8 vs. 93.6%, p value: 0.001; hazard ratio for 1-year mortality: 3.09 [95% confidence interval: 1.55-6.17]). Echocardiographic follow-up data revealed that patients with reduced RV-PA coupling suffer from persistent right ventricular dysfunction (TAPSE: 16.6 ± 4.05 mm vs. 21.6 ± 4.81 mm in patients with preserved RV-PA coupling) and severe tricuspid regurgitation (diagnosed in 19.7 vs. 6.58% in patients with preserved RV-PA coupling). Conclusions: RV-PA coupling expressed as TAPSE/sPAPinvasive can refine stratification of severe aortic stenosis patients into low-risk and high-risk cohorts for mortality after TAVR. Moreover, it can help to anticipate persistent extra-aortic valve cardiac damage, which will demand further treatment.
RESUMO
BACKGROUND: The ISAR-REACT 5 trial compared the efficacy and safety of ticagrelor and prasugrel in patients with ACS managed invasively. The present study sought to investigate the impact of ticagrelor and prasugrel on the incidence and pattern of urgent revascularization in acute coronary syndromes (ACS) patients undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS: This post-hoc analysis of the ISAR-REACT 5 trial included all ACS patients who underwent PCI. The primary endpoint for this analysis was the incidence of urgent revascularization at 12-month follow-up. Secondary outcome was the pattern of urgent revascularization procedures (namely, urgent target vessel/non-target vessel revascularization - TVR/NTVR). Among 3,377 ACS patients who underwent PCI, 1,676 were assigned to ticagrelor and 1,701 to prasugrel before PCI. After 12 months, the incidence of urgent revascularization was higher among patients assigned to ticagrelor as compared to prasugrel (6.8% vs. 5.2%; hazard ratio [HR] = 1.32, 95% confidence interval [CI] 1.00-1.75; p = 0.051), mostly attributable to significantly more urgent NTVR in the ticagrelor group (3.8% vs. 2.4%; HR = 1.62 [1.09-2.41]; p = 0.017). The risk of urgent TVR did not differ between treatment groups (3.3% vs. 3.0%; HR = 1.13 [0.77-1.65]; p = 0.546). CONCLUSIONS: In ACS patients treated with PCI, the cumulative rate of urgent revascularizations after 12 months is higher with ticagrelor compared to prasugrel, due to a significant increase in urgent revascularizations involving remote coronary vessels.

BACKGROUND: In the PREPARE-CALC trial, severely calcified lesion preparation with rotational atherectomy (RA) before biodegradable polymer sirolimus-eluting stent (SES) implantation demonstrated higher procedural success and comparable rates of acute lumen gain and late lumen loss compared to modified balloons (MB) (scoring/cutting). We aimed to analyze the 5-year outcomes of both lesion preparation strategies. METHODS: PREPARE-CALC randomly assigned 200 patients 1:1 to MB or RA, followed by SES implantation. The principal endpoint of the current analysis was target vessel failure (TVF) at 5 years. RESULTS: At 5 years, MB had comparable rates of TVF to RA (19% vs. 21%, HR 1.14, 95% CI 0.60-2.16, p = 0.687). Subgroup analysis showed a lesion length treatment interaction, favoring MB for short lesions and RA for long ones (p for interaction = 0.042). Target lesion revascularization (TLR) was significantly less common with RA (12 vs. 3%, HR 0.28, 95% CI 0.08-0.98, p = 0.048). In a multivariate analysis, RA was independently protective against TLR (adj. HR 0.17, 95% CI 0.04-0.78, p = 0.022), while ostial lesions were associated with higher TLR independent of treatment strategy (adj. HR 11.3, 95% CI 2.98-42.6, p < 0.001). CONCLUSION: In patients with severely calcified coronary lesions, using MB or RA for lesion preparation followed by biodegradable polymer SES implantation was associated with comparable rates of TVF at 5 years. However, a significant reduction of TLR was observed after RA. PREPARE-CALC is the first randomized trial showing potential clinical advantages of RA over MB during long-term follow-up.

BACKGROUND: The optimal antiplatelet regimen after percutaneous coronary intervention (PCI) in patients with peripheral artery disease (PAD) is still debated. This analysis aimed to compare the effect of ticagrelor monotherapy versus ticagrelor plus aspirin in patients with PAD undergoing PCI. METHODS: In the TWILIGHT trial, patients at high ischemic or bleeding risk that underwent PCI were randomized after 3 months of dual antiplatelet therapy (DAPT) to aspirin or matching placebo in addition to open-label ticagrelor for 12 additional months. In this post-hoc analysis, patient cohorts were examined according to the presence or absence of PAD. The primary endpoint was Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding. The key secondary endpoint was a composite of all-cause death, myocardial infarction (MI), or stroke. Endpoints were assessed at 12 months after randomization. RESULTS: Among 7,119 patients, 489 (7%) had PAD and were older, more likely to have comorbidities, and multivessel disease. PAD patients had more bleeding or ischemic complications than no-PAD patients. Ticagrelor monotherapy compared to ticagrelor plus aspirin was associated with less BARC 2, 3, or 5 bleeding in PAD (4.6% vs 8.7%; HR 0.52; 95%CI 0.25-1.07) and no-PAD patients (4.0% vs 7.0%; HR 0.56; 95%CI 0.45-0.69; interaction P-value .830) and a similar risk of death, MI, or stroke in these 2 groups (interaction P-value .446). CONCLUSIONS: Despite their higher ischemic and bleeding risk, patients with PAD undergoing PCI derived a consistent benefit from ticagrelor monotherapy after 3 months of DAPT in terms of bleeding reduction without any relevant increase in ischemic events.

The association between uric acid (UA) and long-term mortality in patients with coronary artery disease is poorly investigated. We assessed the association between UA and 10-year mortality after percutaneous coronary intervention (PCI) in 3,998 patients who underwent PCI. Patients were categorized in groups according to UA tertiles: tertile 1 (UA <5.80 mg/100 ml, n = 1,347), tertile 2 (UA 5.80 to 7.04 mg/100 ml, n = 1,340), and tertile 3 (UA >7.94 mg/100 ml, n = 1,311). The primary outcome was 10-year all-cause mortality. All-cause deaths occurred in 1,200 patients: 320 deaths (26.5%) in patients with UA in the first tertile, 325 deaths (26.9%) in patients with UA in the second tertile, and 555 deaths (46.0%) in patients with UA in the third tertile (adjusted hazard ratio 1.22, 95% confidence interval 1.17 to 1.27, p <0.001) for 1 mg/100 ml increment in UA level. Cardiac deaths occurred in 748 patients: 194 deaths (16.5%) in patients with UA in the first tertile, 202 deaths (17.0%) in patients with UA in the second tertile, and 352 deaths (29.7%) in patients with UA in the third tertile (adjusted hazard ratio 1.24 [1.17 to 1.32], p <0.001) for 1 mg/100 ml increment in the UA level. The 10-year rates of target lesion revascularization, target vessel revascularization, or nontarget vessel revascularization did not differ significantly according to the UA level. In conclusion, in patients with coronary artery disease treated with PCI, increased UA level was associated with higher 10-year mortality. Increased UA level was not associated with the progression of atherosclerosis in nontreated coronary vessels or progression of intimal hyperplasia in stented lesions requiring intervention.

BACKGROUND: The association of aspirin loading with the risk of coronary no-reflow (CNR) after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) has not been investigated. We assessed the association of aspirin loading before PCI with CNR in patients with AMI. MATERIALS AND METHODS: This study included 3100 patients with AMI undergoing PCI. Of them, 2812 patients received aspirin loading (a single oral [or chewed] or intravenous dose of 150-300 mg) and 288 patients did not receive aspirin loading before PCI. The primary endpoint was CNR, defined as Thrombolysis in Myocardial Infarction blood flow grade of <3 after the PCI. RESULTS: CNR occurred in 130 patients: 127 patients in the group with aspirin loading and 3 patients in the group without aspirin loading before PCI (4.5% vs. 1.0%; odds ratio [OR] = 4.50, 95% confidence interval, [1.42-14.21], p = 0.005). After adjustment, the association between aspirin loading and CNR was significant (adjusted OR = 4.49 [1.56-12.92]; p < 0.001). There was no aspirin loading-by-P2Y12 inhibitor (ticagrelor or prasugrel) interaction (pint = 0.465) or aspirin loading-by-chronic aspirin therapy on admission (pint = 0.977) interaction with respect to the occurrence of CNR after PCI. Chronic low-dose aspirin therapy on admission was not independently associated with higher risk of CNR after PCI (adjusted OR = 1.06 [0.65-1.72]; p = 0.824). CONCLUSION: In patients with AMI undergoing PCI, aspirin loading before the PCI procedure at the guideline-recommended doses was associated with higher odds of developing CNR. However, due to the limited number of events, the findings should be considered as hypothesis generating.

BACKGROUND: Modified balloon angioplasty (MB) using a cutting-/scoring balloon or intravascular lithotripsy (IVL) is used in patients with in-stent restenosis (ISR). However, IVL is an off-label use in this setting. The aim of this subgroup analysis of an all-comers registry was to compare IVL to MB angioplasty in patients with ISR. METHODS: The subgroup (n = 117) included all patients with an ISR treated by MB or IVL between 2019 and 2021. Primary endpoint was strategy success (< 20% residual stenosis). The secondary endpoint was cardiac death, acute myocardial infarction (AMI) and target lesion failure/revascularization (TVR). Quantitative coronary angiography was performed in all patients. RESULTS: A total of n = 36 patients were treated by IVL and n = 81 patients by MB. No significant differences in baseline characteristics were observed between the groups. The primary endpoint was reached in 99 patients (84.6%). Patients in the IVL group had less residual stenosis (2.8% vs. 21.0%; p = 0.012). Multivariate regression analysis revealed that IVL had a significant positive effect on reaching the primary end point (Estimate 2.857; standard error (SE) 1.166; p = 0.014). During the follow-up period (450 days) there were no significant differences in rates of cardiac death (IVL n = 2 (1.7%) vs. MB n = 3 (2.6%); p = 0.643), AMI (IVL n = 2 (1.7%) vs. MB n = 4 (3.4%); p = 0.999) and TVR (IVL n = 5 (4.3%) vs. MB n = 14 (12%); p = 0.851). CONCLUSION: IVL results in a significantly lower rate of residual stenosis than MB in patients with ISR. During the long-term follow-up, no differences in rates of cardiac death, AMI or TVR were observed.

Non-adherence has been well recognized for years to be a common issue that significantly impacts clinical outcomes and health care costs. Medication adherence is remarkably low even in the controlled environment of clinical trials where it has potentially complex major implications. Collection of non-adherence data diverge markedly among cardiovascular randomized trials and, even where collected, is rarely incorporated in the statistical analysis to test the consistency of the primary endpoint(s). The imprecision introduced by the inconsistent assessment of non-adherence in clinical trials might confound the estimate of the calculated efficacy of the study drug. Hence, clinical trials may not accurately answer the scientific question posed by regulators, who seek an accurate estimate of the true efficacy and safety of treatment, or the question posed by payers, who want a reliable estimate of the effectiveness of treatment in the marketplace after approval. The Non-adherence Academic Research Consortium is a collaboration among leading academic research organizations, representatives from the U.S. Food and Drug Administration and physician-scientists from the USA and Europe. One in-person meeting was held in Madrid, Spain, culminating in a document describing consensus recommendations for reporting, collecting, and analysing adherence endpoints across clinical trials. The adoption of these recommendations will afford robustness and consistency in the comparative safety and effectiveness evaluation of investigational drugs from early development to post-marketing approval studies. These principles may be useful for regulatory assessment, as well as for monitoring local and regional outcomes to guide quality improvement initiatives.(AU)

BACKGROUND:Although some randomized controlled trials (RCTs) and meta-analyses have suggested that prolonged dual-antiplatelet therapy (DAPT) may be associated with increased mortality, the mechanistic underpinnings of this association remain unclear.OBJECTIVES:The aim of this study was to analyze the associations among bleeding, mortality, and DAPT duration after drug-eluting stent implantation in a meta-analysis of RCTs.METHODS:RCTs comparing different DAPT durations after drug-eluting stent placement were sought through the MEDLINE, Embase, and Cochrane databases and the proceedings of international meetings. Deaths were considered possibly bleeding related if occurring within 1 year of the episodes of bleeding. Primary analysis was by intention-to-treat. Secondary analysis was performed in a modified intention-to-treat population in which events occurring when all patients were on DAPT were excluded.
