Current status of transcatheter aortic valve replacement.

Abstract

The advent of transcatheter aortic valve replacement (TAVR) has modified the treatment of severe aortic stenosis (AS). Large randomized trials and multicenter registries have endorsed the efficacy of TAVR in improving outcomes in patients with severe AS who are inoperable or high surgical risk. There has been a noticeable shift in using TAVR in patients with AS who are not at a high surgical risk. Appropriate diagnosis, patient selection, and referral remain cornerstones to achieving optimal outcomes after TAVR or SAVR (surgical aortic valve replacement).
