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 (R) 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 dass 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.

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

Background Routine manual thrombectomy (MT) is not recommended in primary percutaneous coronary intervention (P-PCI) but it is performed in many procedures. The objective of our study was validating the DDTA score, designed for selecting patients who benefit most from MT. Methods Observational and multicenter study of all consecutive patients undergoing P-PCI in five institutions. Results were compared with the design cohort and the performance of the DDTA was analyzed in all patients. Primary end-point of the analyses was TIMI 3 after MT; secondary endpoints were final TIMI 3, no-reflow incidence, in-hospital mortality and in-hospital major cardiovascular events (MACE). In-hospital prognosis was assessed by the Zwolle risk score. Results Three hundred forty patients were included in the validation cohort and no differences were observed as compared to the design cohort (618 patients) except for lower use of MT and higher IIb/IIIa inhibitors or drug-eluting stents. The probability of TIMI 3 after MT decreased as delay to P-PCI was higher. If DDTA score, MT was associated to TIMI 3 after MT (OR: 4.11) and final TIMI 3 (OR: 2.44). There was a linear and continuous relationship between DDTA score and all endpoints. DDTA score >= 4 was independently associated to lower no-reflow, in-hospital MACE or mortality. The lowest incidence of in-hospital mortality or MACE was in patients who had DDTA score >= 4 and Zwolle risk score 0-3. Conclusions MT is associated to higher rate of final TIMI3 in patients with the DDTA score >= 4. Patients with DDTA score >= 4 had lower no-reflow and in-hospital complications.

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
