Background: Valvular heart disease (VHD) is an important cause of mortality and morbidity and has been subject to important changes in management. The VHD II survey was designed by the EURObservational Research Programme of the European Society of Cardiology to analyze actual management of VHD and to compare practice with guidelines. Methods: Patients with severe native VHD or previous valvular intervention were enrolled prospectively across 28 countries over a 3-month period in 2017. Indications for intervention were considered concordant if the intervention was performed or scheduled in symptomatic patients, corresponding to Class I recommendations specified in the 2012 European Society of Cardiology and in the 2014 American Heart Association/American College of Cardiology VHD guidelines. Results: A total of 7247 patients (4483 hospitalized, 2764 outpatients) were included in 222 centers. Median age was 71 years (interquartile range, 62–80 years); 1917 patients (26.5%) were ≥80 years; and 3416 were female (47.1%). Severe native VHD was present in 5219 patients (72.0%): aortic stenosis in 2152 (41.2% of native VHD), aortic regurgitation in 279 (5.3%), mitral stenosis in 234 (4.5%), mitral regurgitation in 1114 (21.3%; primary in 746 and secondary in 368), multiple left-sided VHD in 1297 (24.9%), and right-sided VHD in 143 (2.7%). Two thousand twenty-eight patients (28.0%) had undergone previous valvular intervention. Intervention was performed in 37.0% and scheduled in 26.8% of patients with native VHD. The decision for intervention was concordant with Class I recommendations in symptomatic patients with severe single left-sided native VHD in 79.4% (95% CI, 77.1–81.6) for aortic stenosis, 77.6% (95% CI, 69.9–84.0) for aortic regurgitation, 68.5% (95% CI, 60.8–75.4) for mitral stenosis, and 71.0% (95% CI, 66.4–75.3) for primary mitral regurgitation. Valvular interventions were performed in 2150 patients during the survey; of them, 47.8% of patients with single left-sided native VHD were in New York Heart Association class III or IV. Transcatheter procedures were performed in 38.7% of patients with aortic stenosis and 16.7% of those with mitral regurgitation. Conclusions: Despite good concordance between Class I recommendations and practice in patients with aortic VHD, the suboptimal number in mitral VHD and late referral for valvular interventions suggest the need to improve further guideline implementation.

Both endocardial and epicardial RF applications are simple and quick to perform and do not pose an additional risk for most patients. Furthermore we believe that it is possible to perform bilateral epicardial radiofrequency ablation of the pulmonary veins without cardiopulmonary bypass. Further refinements of the technique are needed to assure transmurality of all lesions and better results.

Background and aim Left ventricular thrombus is a frequent complication of myocardial infarction (MI) and heart failure with severely depressed ejection fraction. Once diagnosed, anticoagulation for up to 6-months is recommended, but clinical experience with direct oral anticoagulation (DOAC) is limited to a few case reports. Our aim is to test DOAC LV thrombus resolution efficacy against warfarin. Methods Single-centre retrospective cohort study of consecutive patients with recently diagnosed LV thrombus, either after acute myocardial infarction or heart failure with reduced ejection fraction, from January 2009 till December 2018. Thrombus diagnosis and subsequent assessments were performed with echocardiography and complemented with cardiac magnetic resonance, when appropriate. Decisions regarding the type, dose and duration of anticoagulation and any concomitant antiplatelet therapy were left to physician's judgement. Results In a population of 66 patients (51 male, mean age 69±12 years), 13 received DOAC therapy, with the remainder receiving vit. K antagonists. One from each group was lost to follow up. The DOAC subgroup had higher prevalence of atrial fibrillation, higher left ventricular end-diastolic volumes and worse wall motion severity score index (WMSI). The duration of anticoagulant therapy, concomitant single or dual antiplatelet therapy and overall follow up were similar between strategies. Thrombus remission was observed in 91.7% (n=11) and 59.6% (n=31) patients within DOAC and warfarin group, respectively. Risk of unsuccessful resolution was reduced by 35% relative to the warfarin group (RR 0.65; 95% CI [0.491–0.862]; p-value 0.035) (figure). figure Conclusion DOAC seems to be an effective alternative to vitamin-K antagonists in patients with LV thrombus.

Background: In recent years, many important advances have been seen in anticoagulation therapy. However, bleeding risk is still a major concern. Factor XI (FXI) inhibition has emerged as a potential advantageous target to minimize this risk. Objectives:We conducted a systematic review and meta-analysis of current evidence on FXI inhibitors for thromboprophylaxis in major orthopedic surgery. Methods:We performed a systematic search of electronic databases (PubMed, CENTRAL, and Scopus) until May of 2022. Studies were considered eligible if they were randomized controlled trials (RCTs) evaluating FXI inhibitors in thromboprophylaxis versus low molecular weight heparin (LMWH). For analysis purposes, we considered efficacy (venous thromboembolism [VTE], symptomatic VTE) and safety (major and clinically relevant non-major [CRNM] bleeding events, major bleeding events, blood transfusion necessities, adverse events, major adverse events) outcomes.Results: Overall, four RCTs were included, with a total of 2269 patients, 372 VTE events, and 50 major or CRNM bleeding events. Regarding efficacy outcomes, FXI inhibitors were associated with a significant reduction in the incidence of VTE events (odds ratio [OR] 0.50; 95% confidence interval [CI: 0.36, 0.69]). Concerning safety outcomes, FXI inhibitors significantly reduced major or CRNM bleeding events (OR 0.41; 95% CI [0.22, 0.75]). It was also associated with a lower percentage of patients needing a blood transfusion, despite not meeting statistical significance (OR 0.69; 95% CI [0.32, 1.48]). Incidence of adverse events and major adverse events were similar between groups. Conclusion:Factor XI inhibitors showed a significant reduction in the incidence of VTE and bleeding events among patients submitted to major orthopedic surgery.
