  Perspective: Despite multiple limitations of the study, including small sample size, selection bias in terms of surgeon determination as to operative candidacy after failed TAVR, exclusion of patients who might have undergone more complex re-operations after TAVR (e.g., multivalvular surgery, concomitant coronary revascularization, or aortic procedure), missing day status for 15% of the. Conclusions: Technically successful aortic valvuloplasty alters left heart valvar growth in fetuses with aortic stenosis and evolving hypoplastic left heart syndrome and, in a subset of cases, appeared to contribute to a biventricular outcome after birth. Fetal aortic valvuloplasty carries a risk of fetal by: Background— We sought to define patient characteristics, outcomes, and associated risk factors after aortic valve replacement (AVR) in children. Methods and Results— Clinical records from children undergoing AVR from to at our institution were reviewed. Competing-risks methodology determined the time-related prevalence of 3 mutually exclusive end states: death, repeated. Prior studies of stroke and transient ischemic attack (TIA) after transcatheter aortic valve replacement (TAVR) are limited by reporting and follow-up variability. This is a comprehensive analysis of time-related incidence, risk factors, and outcomes of these events.

Background: A significant proportion of patients undergoing transcatheter aortic valve implantation (TAVI) have concomitant peripheral arterial disease (PAD), which plays a crucial role in the preinterventional selection process of determining an optimal vascular access site. The aim of our study was to determine the impact of PAD on clinical outcome after TAVI in a real-world setting. Objectives This study sought to determine the risk factors for post-transcatheter aortic valve replacement (TAVR) dialysis and to determine the impact of pre-TAVR or post-TAVR dialysis on mortality. Background TAVR is now established as an alternative treatment to surgical aortic valve replacement. Data examining the impact of dialysis on outcomes after TAVR are lacking. Coexisting coronary artery disease negatively impacts procedural outcomes and long-term survival in patients undergoing TAVI, and implies that risk assessment and anticipated outcomes might be inaccurate due to stratification as isolated aortic valve replacement rather than AVR+CABG. Comparison of . Given the shared risk factors, PAD is a frequent comorbidity in patients referred for transcatheter aortic valve replacement (TAVR). 4 In clinical trials, the prevalence of PAD in patients undergoing TAVR ranged from % in the PARTNER B (prohibitive risk) trial (Placement of Aortic Transcatheter Valves, Cohort B) to % in the CoreValve US.

Objectives: To investigate the influence of body mass index (BMI) on short- and midterm outcomes following transcatheter aortic valve implantation (TAVI). Background: Although obesity is a major risk factor for cardiovascular mortality, numerous studies reported a beneficial effect of obesity on survival in patients with cardiovascular disease and in patients after cardiac interventions.   The heritability of AD was estimated to be % for genetic factors, and % and % for shared and nonshared environmental factors, respectively. After excluding individuals with Marfan syndrome or bicuspid aortic valve, a family history of AD was associated with a RR of (95% confidence interval [CI], ) for AD.   Bioprosthetic aortic valve calcification density (AVCd) is associated with subsequent hemodynamic valve deterioration, and with increased risk of mortality and re-intervention. The combination of AVCd and echo/Doppler mean gradient progression identified patients at high risk for adverse outcomes.   Among patients with bicuspid aortic valve undergoing TAVR, raphe calcification and leaflet calcification were markers of worse clinical outcomes. The two calcific markers contributed separately and together to worse outcomes, with progressively higher 2-year all-cause mortality associated with neither, with one, or with both.
