Clinical outcomes of self-expandable vs. balloon-expandable TAVI for severe aortic stenosis

Abstract

Background: Transcatheter aortic valve implantation (TAVI) is an established therapy for patients with severe aortic stenosis (AS). There is limited data exploring differences in outcomes post-TAVI SEV vs. BEV. This study compared procedural success and 30-d clinical outcomes self-expandable valves (SEV), vs. balloon-expandable valves (BEV) for patients with severe AS. Methods: Retrospective analysis was undertaken of patients receiving TAVI at St Vincent’s Hospital, Melbourne between August 2009 and May 2018. The primary endpoints included procedural success, clinical outcomes and complication rates at 30-d. Results: Out of 151 patients undergoing TAVI, 70 received (46.3%) SEV (Medtronic Co..
