Chronic anticoagulation with vitamin K antagonists (VKAs) is recommended in patients with hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF). Direct oral anticoagulants (NOACs) are an alternative to VKAs but there are limited data to support their use in HCM. We sought to describe the pattern of use, thromboembolic events, bleeding and quality of life in patients with HCM and AF treated with NOACs. Data from patients treated with NOACs (n=99) and VKA (n=433) at 9 inherited cardiac diseases units were retrospectively collected. Annual rates of embolic events, serious bleeding and death were analysed and compared. Quality of life and treatment satisfaction were evaluated with SF-36 and SAFUCA questionnaires in 80 NOAC-treated and 57 VKA-treated patients. After median follow-up of 63 months (IQR: 26-109), thromboembolic events (TIA/stroke and peripheral embolism) occurred in 10% of patients on oral anticoagulation. Major/clinically relevant bleeding occurred in 3.8% and the global mortality rate was 23.3%. Thromboembolic event rate was 0.62 per 100patient-years in the NOAC group vs. 1.59 in the VKA group [subhazard ratio (SHR) 0.32;95%CI:0.04-2.45; p=0.27]. Major/clinically relevant bleeding occurred in 0.62 per 100person-years in the NOAC group vs. 0.60 in the VKA group (SHR 1.28;95%CI 0.18-9.30; p=0.85). Quality of life scores were similar in both groups; however, NOAC-treated patients achieved higher scores in the SAFUCA. HCM patients with AF on NOACs showed similar embolic and bleeding rates to those on VKA. Although quality of life was similar in both groups, the NOAC group reported higher treatment satisfaction.

Introduction: Device entrapment is a life‐threatening complication during percutaneous coronary intervention (PCI). However, the success for its management is predominantly based on operator experience with limited available guidance in the published literature.Methods: A systematic review was performed on December 2021; we searched PubMed for articles on device entrapment during PCI. In addition, backward snowballing (i.e., review of references from identified articles and pertinent reviews) was employed.Results: A total of 4209 articles were retrieved, of which 150 studies were included in the synthesis of the data. A methodical algorithmic approach to prevention and management of device entrapment can help to optimize outcomes. The recommended sequence of steps are as follows: (a) pulling, (b) trapping, (c) snaring, (d) plaque modification, (e) telescoping, and (f) surgery.Conclusions: In‐depth knowledge of the techniques and necessary tools can help optimize the likelihood of successful equipment retrieval and minimization of complications.

Isolated coronary artery ectasia (CAE) is a relatively rare clinical entity, the pathogenesis of which is poorly understood. More and more evidence is accumulating to suggest a critical inflammatory component. We aimed to elucidate any association between neutrophil to lymphocyte ratio and coronary artery ectasia. A systematic MEDLINE database, ClinicalTrials.gov, medRxiv, Scopus and Cochrane Library search was conducted: 50 studies were deemed relevant, reporting on difference in NLR levels between CAE patients and controls (primary endpoint) and/or on high-sensitive CRP, IL-6, TNF-a and RDW levels (secondary endpoint), and were included in our final analysis. (PROSPERO registration number: CRD42021224195). All inflammatory biomarkers under investigation were found higher in coronary artery ectasia patients as compared to healthy controls (NLR; SMD = 0.73; 95% CI: 0.27–1.20, hs-CRP; SMD = 0.96; 95% CI: 0.64–1.28, IL-6; SMD = 2.68; 95% CI: 0.95–4.41, TNF-a; SMD = 0.50; 95% CI: 0.24–0.75, RDW; SMD = 0.56; 95% CI: 0.26–0.87). The main limitations inherent in this analysis are small case-control studies of moderate quality and high statistical heterogeneity. Our findings underscore that inflammatory dysregulation is implicated in coronary artery ectasia and merits further investigation.

Background: Balloon post‐dilation (BPD) is a widely adopted strategy to optimize acute results of TAVI, with a positive impact on both paravalvular leak and mean gradients. On the other hand, the inflation of the balloon inside prosthetic leaflets may damage them increasing the risk of structural valve deterioration (SVD). Furthermore, the impact of BPD on long‐term clinical outcomes and valve hemodynamics is yet unknown.Aims: To evaluate the impact of BPD on valve durability and long‐term clinical outcomes in patients undergoing self‐expanding transcatheter valve implantation (TAVI).Methods: Echocardiographic and clinical data from the ClinicalService (a nation‐based data repository and medical care project) were analyzed. Patients were divided into two groups, those who underwent BPD after TAVI and those who did not. Coprimary endpoints were all‐cause death and SVD. Cumulative incidence functions for SVD were estimated.Results: Among 1835 patients included in the study, 417 (22.7%) underwent BPD and 1418 (77.3%) did not undergo BPD. No statistically significant differences at 6‐year follow‐up were found between groups in terms of all‐cause mortality (HR: 1.05, 95% CI: 0.9–1.22; p = 0.557) and SVD (2.1% vs. 1.4%, p = 0.381). In addition, BPD did not predispose to higher risk of cardiovascular death, myocardial infarction, valve thrombosis, and endocarditis at 6‐year follow‐up.Conclusions: BPD following TAVI with a self‐expanding prosthesis does not seem to be associated with an increased risk of adverse clinical outcomes or SVD at 6‐year follow‐up.
