RESUMO
INTRODUCTION AND OBJECTIVES: Advanced chronic kidney disease (A-CKD) combined with atrial fibrillation increases the risk of both thrombogenic and bleeding events. Left atrial appendage occlusion (LAAO) may be an alternative to oral anticoagulation to prevent thromboembolic events. We aimed to evaluate the outcomes of LAAO in patients with A-CKD. METHODS: Comparison at long-term follow-up of patients diagnosed with and without A-CKD (eGFR<30 mL/min/1.73 m2 ) who underwent LAAO between 2009 and May 2022. RESULTS: Five hundred seventy-three patients were included. Eighty-one (14%) were diagnosed with A-CKD. There were no differences in sex, age, and cardiovascular risk factors, except for diabetes which was more frequent in patients with A-CKD. The control group had higher rates of stroke, both ischemic and hemorrhagic. There were no differences in the CHA2 DS2 -VASc score, although A-CKD patients had a higher bleeding risk according to the HASBLED scale. Global procedural success was 99.1%. At follow-up, there were no differences in stroke rate: at 1-year (HR: 1.22, IC-95%: 0.14-10.42, p = 0.861); at 5-years (HR: 0.60, IC-95%: 0.08-4.58, p = 0.594). Although bleeding events were higher in the A-CKD group, no differences were found in major bleeding (defined BARC ≥ 3) at 1-year (HR: 1.34, IC-95%: 0.63-2.88, p = 0.464) or at 5-years follow-up (HR: 1.30, IC-95%: 0.69-2.48, p = 0.434). Mortality rate at 5 years was higher in the A-CKD patients (HR: 1.84, IC-95%: 1.18-2.87, p = 0.012). CONCLUSIONS: LAAO is an effective and safe treatment in A-CKD patients to prevent ischemic events and bleeding. This strategy could be an alternative to oral anticoagulation in this high-risk group of patients.

Aims: We aimed to determine whether treatment with sildenafil improves outcomes of patients with persistent pulmonary hypertension (PH) after correction of valvular heart disease (VHD). Methods and results: The sildenafil for improving outcomes after valvular correction (SIOVAC) study was a multricentric, randomized, parallel, and placebo-controlled trial that enrolled stable adults with mean pulmonary artery pressure ≥ 30 mmHg who had undergone a successful valve replacement or repair procedure at least 1 year before inclusion. We assigned 200 patients to receive sildenafil (40 mg three times daily, n = 104) or placebo (n = 96) for 6 months. The primary endpoint was the composite clinical score combining death, hospital admission for heart failure (HF), change in functional class, and patient global self-assessment. Only 27 patients receiving sildenafil improved their composite clinical score, as compared with 44 patients receiving placebo; in contrast 33 patients in the sildenafil group worsened their composite score, as compared with 14 in the placebo group [odds ratio 0.39; 95% confidence interval (CI) 0.22-0.67; P < 0.001]. The Kaplan-Meier estimates for survival without admission due to HF were 0.76 and 0.86 in the sildenafil and placebo groups, respectively (hazard ratio 2.0, 95% CI = 1.0-4.0; log-rank P = 0.044). Changes in 6-min walk test distance, natriuretic peptides, and Doppler-derived systolic pulmonary pressure were similar in both groups. Conclusion: Treatment with sildenafil in patients with persistent PH after successfully corrected VHD is associated to worse clinical outcomes than placebo. Off-label usage of sildenafil for treating this source of left heart disease PH should be avoided. The trial is registered with ClinicalTrials.gov, number NCT00862043.

Iodinated contrast media (CM) are the leading cause of acute renal failure of toxic origin. Between 21% and 50% of patients that receive them develop contrast-induced nephropathy (CIN). All prophylactic measures used so far have failed to provide effective prevention. Since oxidative stress is involved in the damage, a possible preventive strategy could be the administration of antioxidant substances, such as quercetin. This compound has shown renoprotective effects in experimental studies. The aim of this study was to evaluate whether quercetin may be helpful in preventing CIN in patients undergoing coronary catheterization. A clinical phase II study was conducted. Patients were distributed in two groups, namely, CM (patients who only received contrast media) and CM+Q (patients who were pretreated with quercetin orally for 3-5 days). Results showed less incidence of CIN in the CM+Q group, possibly due to glomerular protection, evidenced by a lower increase in serum creatinine and albuminuria; and a lower decrease in the glomerular filtration rate (GFR). Furthermore, in this group, the relative risk of developing CIN observed in patients that received a high dose of contrast media was inferior. In conclusion, this is the first study that demonstrates that quercetin is a promising safe candidate in preventing CIN.

Paravalvular leak (PVL) is an uncommon yet serious complication associated with the implantation of mechanical or bioprosthetic surgical valves and more recently recognized with transcatheter aortic valves implantation (TAVI). A significant number of patients will present with symptoms of congestive heart failure or haemolytic anaemia due to PVL and need further surgical or percutaneous treatment. Until recently, surgery has been the only available therapy for the treatment of clinically significant PVLs despite the significant morbidity and mortality associated with re-operation. Percutaneous treatment of PVLs has emerged as a safe and less invasive alternative, with low complication rates and high technical and clinical success rates. However, it is a complex procedure, which needs to be performed by an experienced team of interventional cardiologists and echocardiographers. This review discusses the current understanding of PVLs, including the utility of imaging techniques in PVL diagnosis and treatment, and the principles, outcomes and complications of transcatheter therapy of PVLs.

Pulmonary vein (PV) stenosis (PVS) is a known complication of PV isolation procedures for AF (atrial fibrillation). PV angioplasty and stenting have been used as an effective therapy for PVS, yet high rates of restenosis are common. Experience with intravascular ultrasound (IVUS) in evaluating the PVS morphological characteristics and appropriate stent deployment is very limited. Furthermore, the use of IVUS could minimise the risk of restenosis. We describe the case of a patient with sub-occlusion of the left superior PV and total occlusion of the left inferior PV following catheter ablation for AF treated by stenting with IVUS guidance.

OBJECTIVE: To evaluate the impact of learning on outcome with use of two different left atrial appendage (LAA) occlusion devices. BACKGROUND: Two self-expanding devices, the Watchman and the Amplatzer Cardiac Plug (ACP), have been used for LAA occlusion in the last few years. It has been demonstrated that complications associated with implantation decrease in frequency with operator experience. However, the role of operator experience has not been compared across the two device types. METHODS: The study comprises 31 consecutive patients who underwent LAA occlusion. We compare the first 10 patients in whom an ACP was implanted with the subsequent eleven patients who underwent ACP implantation and with 10 cases where a Watcthman device was implanted. The composite safety end point comprised procedure-related events and excessive bleeding events. We also performed 3 months echocardiographic and clinical follow-up. RESULTS: There were not significant differences in the basal clinical and echocardiographical characteristics across the three groups. Cardiac complications only occurred in the ACP initial experience group (9% vs. 0% vs. 0% P = 0.04). Echocardiographic and clinical follow-up at 3 months was completed in all patients. No significant residual leak was detected. One patient in the ACP initial experience group developed a thrombus on the device. One patient in ACP late experience presented an ischemic stroke. CONCLUSIONS: Complications associated with LAA occlusion cluster early in the peri-procedural period and significantly decrease in frequency with operator experience. Initial experience gained with one of device may improve outcome with use of alternative LAA occlusion devices.

INTRODUCTION AND OBJECTIVES: Transfemoral access is the most frequently used vascular approach in chronic total occlusion percutaneous coronary interventions (CTO-PCI). The aim of this study was to evaluate the safety and feasibility of a transradial access CTO-PCI program and its impact on angiographic and clinical results and length of hospital stay. METHODS: Retrospective multicenter cohort study including 2550 consecutive CTO-PCI procedures included in a multicenter registry with accurate information on vascular access. A total of 896 procedures were performed as radial-only access while 1654 were performed through at least 1 femoral puncture. Clinical and angiographic data were collected. RESULTS: The mean age was 66.3± 11.4 years. The mean Japan-chronic total occlusion score (2.7±0.3) was similar in the 2 groups. Successful revascularization was achieved in 2009 (79.6%) cases, 78.2% and 82.1% in the femoral and radial access cohorts, respectively (P=.002). Periprocedural in-hospital complications were observed in 5.1% and 2.3% (P=.02), with fewer access site-dependant vascular complications in the transradial cohort (2.3% vs 0.2%; P=.009). The mean length of hospital stay was significantly shorter in the transradial access group (0.89±1.4 vs 2.2±3.2 days, P<.001). CONCLUSIONS: A transradial program for CTO-PCI is safe and effective in most CTO lesions. The transradial strategy has fewer vascular complications and shorter length of hospital stay without compromising the success rate.

BACKGROUND: It is unknown whether the availability of long drug-eluting stents modify the PCI strategy of long CTO. To describe the contemporary PCI strategy of long chronic total occlusions (CTO) using overlapping (OS) or single long stents (SS) and to analyze its results. METHODS: 2842 consecutive CTO PCIs were included. Those with an occlusion length ≥20 mm in which ≥1 drug eluting stent (DES) was implanted were analyzed. We compared procedural characteristics and clinical outcomes of CTO treated with OS or SS. RESULTS: 1088 CTO PCIs were analyzed (79.9% males; 64.7±10.6 years). Mean J-score was 2.8±0.9. A SS was used in 38.5% of cases and OS in 61.5%. Total stent length was 64.1±29.9 mm; it was higher in the OS group (OS: 79.9±25.5 mm vs. SS: 38.3±14.7 mm; P<0.0001). Mean number of stents in the OS group was 2.3±1. Very long stents (≥40 mm) were used in 27.4% of cases, more frequently in the OS group (OS:32.4% vs. SS:19.3%; P<0.0001). After a mean follow-up of 19±15.9 months, the rate of adverse events (MACE) was 2% (cardiac death: 1.6%, myocardial infarction: 1.6%, target lesion revascularization: 1.9% and stent thrombosis: 0.18%) with no significant differences between both groups. Overlapping was not an independent predictor of MACE. CONCLUSIONS: In long CTO PCIs, OS is more frequently used than single stenting, especially in more complex procedures. Clinical outcomes at a mid-term follow-up are favorable. Using newer generation DES, overlapping was not an independent predictor of MACE; however, a trend toward a higher event rate was observed in the OS group.

A 56-year-old male presented with angina pectoris despite optimal medical treatment. A coronary computed tomography angiography revealed a chronic total occlusion of the proximal right coronary artery with a moderately calcified long path, and a chronic total occlusion of the distal circumflex. In selected cases with long occlusions and the need for a hybrid approach, the use of computed tomography angiography fusion could help to identify the right wire position, prevent perforations, reduce the use of contrast and fluoroscopy time, improve patient safety, and increase success rate.

INTRODUCTION AND OBJECTIVES: ST-segment elevation myocardial infarction (STEMI) networks should guarantee STEMI care with good clinical results and within the recommended time parameters. There is no contemporary information on the performance of these networks in Spain. The objective of this study was to analyze the clinical characteristics of patients, times to reperfusion, characteristics of the intervention performed, and 30-day mortality. METHODS: Prospective, observational, multicenter registry of consecutive patients treated in 17 STEMI networks in Spain (83 centers with the Infarction Code), between April 1 and June 30, 2019. RESULTS: A total of 5401 patients were attended (mean age, 64±13 years; 76.9% male), of which 4366 (80.8%) had confirmed STEMI. Of these, 87.5% were treated with primary angioplasty, 4.4% with fibrinolysis, and 8.1% did not receive reperfusion. In patients treated with primary angioplasty, the time between symptom onset and reperfusion was 193 [135-315] minutes and the time between first medical contact and reperfusion was 107 [80-146] minutes. Overall 30-day mortality due to STEMI was 7.9%, while mortality in patients treated with primary angioplasty was 6.8%. CONCLUSIONS: Most patients with STEMI were treated with primary angioplasty. In more than half of the patients, the time from first medical contact to reperfusion was <120 minutes. Mortality at 30 days was relatively low.

BACKGROUND: Sex and prior cardiovascular disease (CVD) are known independent prognostic factors following an ST-elevation myocardial infarction (STEMI). We aimed to examine whether the association between sex and 30-day mortality differ according to the presence of previous CVD in STEMI patients. METHODS: Prospective, observational, multicentre registry of consecutive patients managed in 17 STEMI networks in Spain (83 centres), between April and June 2019. Unadjusted and adjusted logistic regression models assessed the association of 30-day mortality with sex and prior CVD status, as well as their interaction. RESULTS: Among 4366 patients (mean age 63.7 ± 13.0 years; 78% male), there were 337 (8.1%) deaths within the first 30 days. There was an association between crude 30-day mortality and sex (women 10.4% vs. men 7.4%, p = 0.003), and prior CVD (CVD 13.7% vs non-CVD 6.8%, p < 0.001). After adjustment for potential confounding, neither sex nor prior CVD were apparently associated with mortality. Nevertheless, we found a significant sex-CVD interaction (p-interaction = 0.006), since women were at lower risk than men in the subset of patients with prior CVD (OR = 0.30, 95%CI = 0.12-0.80) but not in those without CVD (OR = 1.17, 95%CI = 0.79-1.74). CONCLUSIONS: Women as well as patients with prior CVD have an increased crude risk of 30-day mortality. However, sex-related differences in short term mortality are modulated by the interaction with CVD in STEMI patients. Compared to men, women had a similar prognosis in the subset of patients without CVD, whereas they were associated with a lower risk of mortality among those with prior CVD after adjusting for other prognostic factors.

BACKGROUND: Paravalvular leak occurs in 5-17% of patients following surgical valve replacement, more often in mitral position. The prognosis without treatment is poor. Percutaneous device closure represents an alternative to repeat surgery. The objective of this work is to evaluate the medium and long-term results in the percutaneous closure of PVL in mitral prosthesis. METHODS: This observational study is based on a retrospective registry including consecutive mitral PVL cases undergoing percutaneous closure at a single tertiary-care center from April 2010 to December 2020. The safety and efficacy results of the procedure, at 90 days and in the long term, were analyzed. Also, predictors of procedure failure and long-term events were identified. RESULTS: A total of 128 consecutive mitral paravalvular leak closure procedures were included. Technical success was achieved in 115 (89.8%) procedures. The presence of multiple PVLs was the sole factor that independently predicted procedural failure. Median follow-up of our sample was 41.8 months (mean 47.7 ± 35.7 months). Underlying hemolytic anemia as the indication for PVL closure, a recent admission for decompensated HF, and lack of improvement in functional class emerged as consistent predictors of MACE and death during long-term follow-up, while lack of procedural success during the first PVL procedure and chronic kidney disease were also associated with MACE during follow-up. CONCLUSIONS: Percutaneous mitral PVL closure displayed high technical and procedural success rates, with an acceptable safety profile, in a high-risk population. Percutaneous mitral PVL closure achieved an improvement in short- and long-term functional class and a reduction of hemolysis in the vast majority of patients. In addition, long-term survival in our study was good, in particular for patients undergoing successful PVL closure procedures.
RESUMO
BACKGROUND: Severe tricuspid regurgitation (TR) is frequently associated with significant morbidity and mortality; such patients are often deemed to be at high surgical risk. Heterotopic bicaval stenting is an emerging, attractive transcatheter solution for these patients. OBJECTIVES: The aim of this study was to evaluate the 30-day safety and 6-month efficacy outcomes of specifically designed bioprosthetic valves for the superior and inferior vena cava. METHODS: TRICUS EURO (Safety and Efficacy of the TricValve® Transcatheter Bicaval Valves System in the Superior and Inferior Vena Cava in Patients With Severe Tricuspid Regurgitation) is a nonblinded, nonrandomized, single-arm, multicenter, prospective trial that enrolled patients from 12 European centers between December 2019 and February 2021. High-risk individuals with severe symptomatic TR despite optimal medical therapy were included. The primary endpoint was quality-of-life (QOL) improvement measured by Kansas City Cardiomyopathy Questionnaire score and New York Heart Association (NYHA) functional class improvement at 6-month follow-up. RESULTS: Thirty-five patients (mean age 76 ± 6.8 years, 83% women) were treated using the TricValve system. All patients at baseline were in NYHA functional class III or IV. At 30 days, procedural success was 94%, with no procedural deaths or conversions to surgery. A significant increase in QOL at 6 months follow-up was observed (baseline and 6-month Kansas City Cardiomyopathy Questionnaire scores 42.01 ± 22.3 and 59.7 ± 23.6, respectively; P = 0.004), correlating with a significant improvement in NYHA functional class, with 79.4% of patients noted to be in functional class I or II at 6 months (P = 0.0006). The rates of 6-month all-cause mortality and heart failure hospitalization were 8.5% and 20%, respectively. CONCLUSIONS: The dedicated bicaval system for treating severe symptomatic TR was associated with a high procedural success rate and significant improvements in both QOL and functional classification at 6 months follow-up.

INTRODUCTION AND OBJECTIVES: Severe calcification is present in> 50% of coronary chronic total occlusions (CTOs) undergoing percutaneous intervention. We aimed to describe the contemporary use and outcomes of plaque modification devices (PMDs) in this context. METHODS: Patients were included in the prospective, consecutive Iberian CTO registry (32 centers in Spain and Portugal), from 2015 to 2020. Comparison was performed according to the use of PMDs. RESULTS: Among 2235 patients, wire crossing was achieved in 1900 patients and PMDs were used in 134 patients (7%), requiring more than 1 PMD in 24 patients (1%). The selected PMDs were rotational atherectomy (35.1%), lithotripsy (5.2%), laser (11.2%), cutting/scoring balloons (27.6%), OPN balloons (2.9%), or a combination of PMDs (18%). PMDs were used in older patients, with greater cardiovascular burden, and higher Syntax and J-CTO scores. This greater complexity was associated with longer procedural time but similar total stent length (52 vs 57mm; P=.105). If the wire crossed, the procedural success rate was 87.2% but increased to 96.3% when PMDs were used (P=.001). Conversely, PMDs were not associated with a higher rate of procedural complications (3.7 vs 3.2%; P=.615). Despite the worse baseline profile, at 2 years of follow-up there were no differences in the survival rate (PMDs: 94.3% vs no-PMDs: 94.3%, respectively; P=.967). CONCLUSIONS: Following successful wire crossing in CTOs, PMDs were used in 7% of the lesions with an increased success rate. Mid-term outcomes were comparable despite their worse baseline profile, suggesting that broader use of PMDs in this setting might have potential technical and prognostic benefits.

The feasibility and safety of left atrial appendage closure with the Amplatzer cardiac plug (AGA Medical Corp., Minneapolis, MN) have been recently published; no thrombus formation on the device surface has been reported previously. We describe a case of a 66-year-old man with permanent atrial fibrillation, previous stroke, and contraindication for long-term oral anticoagulant therapy. A 22-mm ACP device was deployed successfully without complications. The patient was discharged on acetyl salicylic acid 100 mg and clopidogrel 75 mg daily. After 4 weeks, the patient was admitted for a lower gastrointestinal bleeding and clopidogrel was stopped. A 3-month follow-up echocardiogram confirmed the exclusion of the LAA but it demonstrated the presence of a thrombus on the atrial surface of the device. It was decided to keep the patient on acetyl salicylic acid 100 mg with the addition of enoxaparin 60 mg bid. Transesophageal echocardiogram demonstrated total resolution of the thrombus after 2 months.

OBJECTIVE: To analyze the differences in anatomical, clinical and echocardiographic characteristics of women and men undergoing PMV and to evaluate the relationship between sex, PMV success, and immediate and long-term clinical outcome. BACKGROUND: Rheumatic mitral stenosis (MS) is predominantly a disease of middle-aged women. Percutaneous mitral valvuloplasty (PMV) has become the standard of care for suitable patients. However little is known about the relationship between sex, PMV success, and procedural outcome. METHODS AND RESULTS: We evaluated measures of procedural success and clinical outcome in consecutive patients (839 women and 176 men) who underwent PMV. Despite a lower baseline echocardiographic score (7.47 ± 2.15 vs. 8.02 ± 2.18, P = 0.002), women were less likely to achieve PMV success (69% vs. 83%, adjusted OR 0.44, 95% CI 0.27-0.74, P = 0.002), and had a smaller post-procedural MV area (1.86 ± 0.7 vs. 2.07 ± 0.7 cm(2), P < 0.001). Overall procedural and in-hospital complication rates did not differ significantly between women and men. However, women were significantly more likely to develop severe MR immediately post PMV (adjusted OR 2.41, 95% CI 1.0-5.83, P = 0.05) and to undergo MV surgery (adjusted HR 1.54, 95% CI 1.03-2.3, P = 0.037) after a median follow-up of 3.1 years. CONCLUSIONS: Compared to men, women with rheumatic MS who undergo PMV are less likely to have a successful outcome and more likely to require MV surgery on long-term follow-up despite more favorable baseline MV anatomy.

AIMS: The aim of this study was to assess clinical and prognosis differences in patients with COVID-19 and STEMI. METHODS AND RESULTS: Using a nationwide registry of consecutive patients managed within 42 specific STEMI care networks, we compared patient and procedure characteristics and in-hospital outcomes in two different cohorts, according to whether or not they had COVID-19. Among 1,010 consecutive STEMI patients, 91 were identified as having COVID-19 (9.0%). With the exception of smoking status (more frequent in non-COVID-19 patients) and previous coronary artery disease (more frequent in COVID-19 patients), clinical characteristics were similar between the groups, but COVID-19 patients had more heart failure on arrival (31.9% vs 18.4%, p=0.002). Mechanical thrombectomy (44% vs 33.5%, p=0.046) and GP IIb/IIIa inhibitor administration (20.9% vs 11.2%, p=0.007) were more frequent in COVID-19 patients, who had an increased in-hospital mortality (23.1% vs 5.7%, p<0.0001), that remained consistent after adjustment for age, sex, Killip class and ischaemic time (OR 4.85, 95% CI: 2.04-11.51; p<0.001). COVID-19 patients had an increase of stent thrombosis (3.3% vs 0.8%, p=0.020) and cardiogenic shock development after PCI (9.9% vs 3.8%, p=0.007). CONCLUSIONS: Our study revealed a significant increase in in-hospital mortality, stent thrombosis and cardiogenic shock development after PCI in patients with STEMI and COVID-19 in comparison with contemporaneous non-COVID-19 STEMI patients.

Background The determinants and consequences of pulmonary hypertension after successfully corrected valvular heart disease remain poorly understood. We aim to clarify the hemodynamic bases and risk factors for mortality in patients with this condition. Methods and Results We analyzed long-term follow-up data of 222 patients with pulmonary hypertension and valvular heart disease successfully corrected at least 1 year before enrollment who had undergone comprehensive hemodynamic and imaging characterization as per the SIOVAC (Sildenafil for Improving Outcomes After Valvular Correction) clinical trial. Median (interquartile range) mean pulmonary pressure was 37 mm Hg (32-44 mm Hg) and pulmonary artery wedge pressure was 23 mm Hg (18-26 mm Hg). Most patients were classified either as having combined precapillary and postcapillary or isolated postcapillary pulmonary hypertension. After a median follow-up of 4.5 years, 91 deaths accounted for 4.21 higher-than-expected mortality in the age-matched population. Risk factors for mortality were male sex, older age, diabetes mellitus, World Health Organization functional class III and higher pulmonary vascular resistance-either measured by catheterization or approximated from ultrasound data. Higher pulmonary vascular resistance was related to diabetes mellitus and smaller residual aortic and mitral valve areas. In turn, the latter correlated with prosthetic nominal size. Six-month changes in the composite clinical score and in the 6-minute walk test distance were related to survival. Conclusions Persistent valvular heart disease-pulmonary hypertension is an ominous disease that is almost universally associated with elevated pulmonary artery wedge pressure. Pulmonary vascular resistance is a major determinant of mortality in this condition and is related to diabetes mellitus and the residual effective area of the corrected valve. These findings have important implications for individualizing valve correction procedures. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT00862043.

BACKGROUND: We aimed to compare the performance of the recent CASTLE score to J-CTO, CL and PROGRESS CTO scores in a comprehensive database of percutaneous coronary intervention of chronic total occlusion procedures. METHODS: Scores were calculated using raw data from 1,342 chronic total occlusion procedures included in REBECO Registry that includes learning and expert operators. Calibration, discrimination and reclassification were evaluated and compared. RESULTS: Mean score values were: CASTLE 1.60±1.10, J-CTO 2.15±1.24, PROGRESS 1.68±0.94 and CL 2.52±1.52 points. The overall percutaneous coronary intervention success rate was 77.8%. Calibration was good for CASTLE and CL, but not for J-CTO or PROGRESS scores. Discrimination: the area under the curve (AUC) of CASTLE (0.633) was significantly higher than PROGRESS (0.557) and similar to J-CTO (0.628) and CL (0.652). Reclassification: CASTLE, as assessed by integrated discrimination improvement, was superior to PROGRESS (integrated discrimination improvement +0.036, p<0.001), similar to J-CTO and slightly inferior to CL score (- 0.011, p = 0.004). Regarding net reclassification improvement, CASTLE reclassified better than PROGRESS (overall continuous net reclassification improvement 0.379, p<0.001) in roughly 20% of cases. CONCLUSION: Procedural percutaneous coronary intervention difficulty is not consistently depicted by available chronic total occlusion scores and is influenced by the characteristics of each chronic total occlusion cohort. In our study population, including expert and learning operators, the CASTLE score had slightly better overall performance along with CL score. However, we found only intermediate performance in the c-statistic predicting chronic total occlusion success among all scores.

INTRODUCTION AND OBJECTIVES: The COVID-19 outbreak has had an unclear impact on the treatment and outcomes of patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to assess changes in STEMI management during the COVID-19 outbreak. METHODS: Using a multicenter, nationwide, retrospective, observational registry of consecutive patients who were managed in 75 specific STEMI care centers in Spain, we compared patient and procedural characteristics and in-hospital outcomes in 2 different cohorts with 30-day follow-up according to whether the patients had been treated before or after COVID-19. RESULTS: Suspected STEMI patients treated in STEMI networks decreased by 27.6% and patients with confirmed STEMI fell from 1305 to 1009 (22.7%). There were no differences in reperfusion strategy (> 94% treated with primary percutaneous coronary intervention in both cohorts). Patients treated with primary percutaneous coronary intervention during the COVID-19 outbreak had a longer ischemic time (233 [150-375] vs 200 [140-332] minutes, P < .001) but showed no differences in the time from first medical contact to reperfusion. In-hospital mortality was higher during COVID-19 (7.5% vs 5.1%; unadjusted OR, 1.50; 95%CI, 1.07-2.11; P < .001); this association remained after adjustment for confounders (risk-adjusted OR, 1.88; 95%CI, 1.12-3.14; P = .017). In the 2020 cohort, there was a 6.3% incidence of confirmed SARS-CoV-2 infection during hospitalization. CONCLUSIONS: The number of STEMI patients treated during the current COVID-19 outbreak fell vs the previous year and there was an increase in the median time from symptom onset to reperfusion and a significant 2-fold increase in the rate of in-hospital mortality. No changes in reperfusion strategy were detected, with primary percutaneous coronary intervention performed for the vast majority of patients. The co-existence of STEMI and SARS-CoV-2 infection was relatively infrequent.
