Exercise is overwhelmingly beneficial for physical and mental health, but for some people exercise addiction (EA) can develop and negatively impact an individual. This study sought to (a) compare the latent structure of two instruments assessing EA and (b) examine differences in attitudes toward stopping exercise, if required to on medical grounds, among exercise-addicted and non-addicted athletes. In a cross-sectional study, 1,011 athletes competing at different levels completed an anonymous on-line survey. The survey contained Exercise Dependence Scale-Revised (EDS-R), Exercise Addiction Inventory (EAI), and questions on adherence to medical prescriptions to stop exercise. We tested the latent structure of EDS-R and EAI with multigroup confirmatory factor analyses (CFA), across gender and competition level. Finally, we measured the difference of athletes' attitudes toward stopping exercise, if prescribed by a physician. Both instruments showed good fit indexes, even across gender. CFAs on EAI scores showed some violations of measurement invariance across competition level (ΔCFI = .03; ΔRMSEA = .02). On the contrary, CFAs on EDS-R scores did not show invariance violations across competition level (ΔCFI =

Aims: The aim of this study was to evaluate 30-day safety and efficacy outcomes of transcatheter aortic valve implantation (TAVI) performed with the SAPIEN 3 Ultra system. Methods and results: The S3U registry is a physician-led, post-approval, multicentre, observational registry of transfemoral TAVI with the SAPIEN 3 Ultra. New features include an improved sealing skirt, a 14 Fr expandable sheath and a new delivery catheter. Overall, 139 consecutive patients at nine participating centres were enrolled. Mean age was 81.4 +/- 8.3 years, average STS score 3.8 +/- 2.4%. The vast majority (97.2%) underwent TAVI with local anaesthesia (28.8%) or conscious sedation (68.3%). Balloon predilatation was performed in 30 patients (21.6%), post-dilatation in three (2.2%). In-hospital, there were no cases of death, stroke, or conversion to open heart surgery. Major vascular complications occurred in three patients (2.2%), as well as major or life-threatening bleedings in three patients (2.2%). There were two moderate (1.4%) and no moderate/severe paravalvular leaks. Median length of stay after TAVI was three days (IQR 3-5 days). At 30 days, there were no deaths, MI, or strokes, and the incidence of new permanent pacemaker implantation was 4.4%. Conclusions: This first multicentre international experience of transfemoral TAVI with the SAPIEN 3 Ultra transcatheter heart valve shows good in-hospital and 30-day clinical outcomes.

Background: Coronary access (CA) after transcatheter aortic valve replacement (TAVR) with supra-annular transcatheter heart valves (THV) can be challenging. Specific Evolut R/Pro and Acurate Neo THVs orientations are associated with reduced neo-commissure overlap with coronary ostia, while SAPIEN 3 THV cannot be oriented. With the ALIGN-ACCESS study (TAVR With Commissural Alignment Followed by Coronary Access), we investigated the impact of commissural alignment on the feasibility of CA after TAVR. Methods: We performed coronary angiography after TAVR with intra-annular SAPIEN 3, supra-annular Evolut R/Pro, and Acurate Neo THVs in 206 patients. Evolut THVs were implanted aiming for commissure alignment. Alignment of Acurate Neo was retrospectively assessed in 36, intentionally attempted in 26 cases. The primary end point was the rate of unfeasible and nonselective CA after TAVR. Results: Thirty-eight percent of patients received SAPIEN 3, 31.1% Evolut Pro/R, 30.1% Acurate Neo THV. Final valve orientation was favorable to commissural alignment in 85.9% of Evolut and 69.4% of Acurate Neo cases (with intentional alignment successful in 88.5%). Selective CA was higher for SAPIEN 3 than for aligned and misaligned supra-annular THVs (95% versus 71% versus 46%, P P P =0.03), and THV–sinus of Valsalva relation (odds ratio, 1.06 [95% CI, 1.02–1.1]; P Conclusions: Commissural alignment improves the rate of selective CA after TAVR with supra-annular THVs. Nevertheless, aligned supra-annular THVs carry higher risk of unfeasible/nonselective CA than SAPIEN 3. Patients with a misaligned supra-annular THV, low sinus of Valsalva, and higher THV–sinus of Valsalva relation are at highest risk of impaired CA after TAVR.

Acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) is a life-threatening condition frequently encounter in patients with multivessel coronary artery disease (MVD).Despite prompt revascularization, in particular percutaneous coronary intervention (PCI), and therapeutic and technological advances, the mortality rate for CS related to AMI remains high. Differently from hemodynamically stable setting, a culprit lesion-only (CLO) revascularization strategy is currently suggested in AMI-CS patients, based on the results of a recent randomized evidence burdened by several limitations and conflicting results from non-randomized studies. Furthermore, mechanical circulatory support (MCS) devices have raised as a key therapeutic option in CS, especially in case of an early implantation without delaying revascularization and before irreversible organ damage has occurred. We provide an in-depth review of current evidences on optimal revascularization strategies of multivessel CAD in infarct-related CS, assessing the role of MCS devices, and highlighting the importance of shock teams and medical care system networks to effectively impact on clinical outcomes.Emerging observational experience suggested that an early implantation of MCS (prior to PCI), the performance of an extensive revascularization and the implementation of shock teams and networks are key factors for improving clinical outcomes.

Aims Cardiac complications are a leading cause of mortality after orthotopic liver transplantation (LT) and pre-operative risk stratification is challenging. We evaluated whether coronary artery calcium (CAC) score calculated on a standard (non-thin layer, non-ECG gated) chest computed tomography (CT) predicted cardiac outcome after LT. Methods We included a consecutive series of LT recipients who underwent pre-operative cardiac evaluation including stress-testing or cardiac catheterization in high-risk patients. Patients with a history of coronary artery disease or coronary revascularization were excluded. The CAC score was calculated from the chest CT routinely performed before LT. CAC values were not available at the time of pre-transplant cardiac evaluation and did not affect LT eligibility. The primary end-point included peri-operative arrhythmic cardiac arrest and sustained ventricular arrhythmias; heart failure, myocardial infarction and cardiac death within 1-year after LT. Results The study population consisted of 301 patients (median age 56 years, 76% males). At chest CT, 49% had CAC = 0; 27% had CAC = 1–99, 15% had CAC = 100–399 and 9% CAC > 400. The primary end-point incidence increased from 7% in patients with CAC = 0 to 27% in patients with CAC > 400 (p = 0.007). At multivariable analysis including traditional risk factors, CAC remained an independent predictor of cardiac events (p = 0.01). Conclusions CAC score calculated on a standard chest CT stratified the risk of cardiac events in patients who underwent LT after negative pre-transplant cardiac evaluation. These findings suggest that evaluation of CAC from a standard chest CT performed for other reasons can be used as an early cardiac risk stratification tool before LT.

Background: Conduction disturbances after transcatheter aortic valve replacement (TAVR) are often transient. Limited data exist on anatomic factors predisposing to pacemaker dependency after TAVR. We sought to assess the rate and the possible predictors of pacemaker dependency after TAVR. Methods: Consecutive patients undergoing pacemaker implantation up to 30 days after TAVR between May 2014 and September 2019 were included. Baseline electrocardiographic, computed tomography, and procedural characteristics were collected, including valve implantation depth and membranous septum length, an anatomic surrogate of the distance between the aortic annulus and the His bundle. Pacemaker dependency at 30 days and 1 year and all-cause mortality during follow-up were evaluated. Results: Of 728 TAVR patients, 112 (53.5% men; median age, 81 years) underwent pacemaker implantation after TAVR. Of these, 44.6% (50 of 112) were pacemaker dependent at 30 days and 46.7% (36 of 77) at 1 year. By multivariate analysis, independent predictors of 30-day pacemaker dependency included left ventricular outflow tract calcifications under the left coronary cusp (odds ratio, 5.69 [95% CI, 1.45–22.31]; P =0.013) and a difference between membranous septum length and implantation depth (ΔMSID) ≥3 mm (odds ratio, 7.58 [95% CI, 2.07–27.78]; P =0.002). Conversely, membranous septum length and implantation depth alone were not associated with pacemaker dependency (odds ratio, 0.79 [95% CI, 0.60–1.05]; P =0.11 and odds ratio, 1.11 [95% CI, 0.99–1.24]; P =0.08). At a median follow-up of 28.1 (11.7–48.6) months, pacemaker-dependent patients did not show a worse survival ( P =0.26). Conclusions: Less than half of the patients undergoing pacemaker implantation after TAVR are pacemaker-dependent at midterm follow-up. ΔMSID ≥3 mm and the presence of left ventricular outflow tract calcifications under the left coronary cusp, but not membranous septum length nor implantation depth alone, are predictive of long-term pacemaker dependency after TAVR, thus influencing device selection and programming.

Background Incidence of coronary access (CA) after transcatheter aortic valve replacement (TAVR) at long-term follow-up remains unknown. CA and percutaneous coronary intervention (PCI) after TAVR might present technical challenges, particularly with supra-annular devices. Methods Patients undergoing CA after being treated with TAVR at our institution were included in the study. Coronary interventions for coronary obstruction during TAVR procedure were excluded. Incidence, feasibility and outcomes of CA after TAVR were analyzed. Results Out of 912 patients aged 80 ± 7 years treated with TAVR at our institution between 2007 and 2018, 48 (5.3%) underwent CA at a median follow up of 769 [363-1,471] days. Twenty-one had received a SAPIEN XT, 15 a SAPIEN 3, 6 Corevalve, 2 Evolut Pro, 2 JenaValve, and 2 Lotus valve. PCI was indicated in 26 (54%) cases. Seventeen (35%) procedures were performed for acute coronary syndromes (ACS). Independent predictors of CA after TAVR were younger age, previous PCI, and CABG. CA of both vessels was feasible in all patients with an intra-annular device, while the right coronary artery was not engaged in two patients with a supra-annular valve. PCI was successful in all but one case. All-cause mortality was similar between patients needing CA for ACS and those who had other clinical indications. Conclusions In this high-risk AS population, incidence of CA after TAVR at long-term follow-up was rather low. CA and PCI were safe and successful in most cases, with a lower rate of selective CA for supra-annular devices.

Transcatheter aortic valve implantation (TAVI) has been a revolution in the treatment of severe aortic stenosis evolving to a high procedural success rate and low rate of complications. Embolization of the percutaneous device is a rare but potentially life-threatening complication. The spectrum of clinical manifestations ranges between incidental finding on cardiac imaging to cardiogenic shock or cardiac arrest. Data about predictors and management of transcatheter heart valve embolization are scarce and mostly anecdotical. Management strategies are related to the type, the size, the location of the embolized device, the timing of diagnosis, and the clinical presentation of the patient. According to recent data from TRAVEL registry, device embolization and migration occur in approximately 1% of the patients and is responsible for increased morbidity and mortality. However, in a considerable proportion of cases it could have been prevented, hence structural interventionalists should plan the procedures carefully and know thoroughly the risk factors for device embolization. Increased awareness of predisposing factors, preventive measures, and appropriate bail-out options and techniques are strongly advisable. This paper is a review of the incidence, and outcomes of percutaneous prosthesis embolization during TAVI. It also suggests an integrated algorithmic approach for the management of device embolization incorporating both percutaneous and surgical techniques.

AIMS Identification of silent cardiovascular diseases by preparticipation evaluation (PPE) and disqualification from competitive sports have the potential to prevent sudden death but may induce adverse psychological consequences, particularly for exercise addicted athletes. We investigated the relationship between exercise addiction, attitude towards PPE and reaction to cardiovascular disease diagnosis. METHODS We invited Italian competitive athletes to participate in an online questionnaire investigating exercise addiction, opinion about mandatory PPE and potential reaction to both sports disqualification and hypothetical diagnosis of different cardiovascular diseases. RESULTS The survey was completed by 1011 athletes (75% men, median age 30 years) encompassing a wide range of sports disciplines and competition levels. According to the 'Exercise Dependence Scale-21', 6% were classified as exercise addicted. The vast majority of both exercise addicted and nonexercise addicted athletes agreed that PPE should be mandatory (92 and 96%, P = 0.17) and that the eligibility decision should be left to the sports medicine physician (82 and 89%, P = 0.08). In case a cardiovascular disease is identified, a higher proportion of exercise addicted athletes would undergo 'open-heart' surgery if this would allow resuming high-intensity sport (54 versus 31%, P
