TMVR with balloon-expandable aortic valves in extreme surgical risk patients with severe MAC is feasible but associated with high 30-day and 1-year mortality. Most patients who survive the 30-day post-procedural period are alive at 1 year and have sustained improvement of symptoms and transcatheter valve performance. The role of TMVR in patients with MAC requires further evaluation in clinical trials.
This single-center series suggests that transfemoral THV implantation for deterioration of mitral bioprosthesis or surgical repair is feasible in selected patients and improves early hemodynamic and midterm functional status.
About one-third of patients discharged alive after TAVI were alive at 6-year follow-up, and the survivors exhibited good functional results assessed by NYHA class and quality-of-life standardised evaluation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
