SELF EXPANDABLE VALVES HAVE LOWER PARAVALVULAR LEAK TWO YEARS AFTER TRANSCATHETER AORTIC VALVE REPLACEMENT COMPARED WITH BALLOON VALVES: RESULTS FROM THE MARSHFIELD AORTIC VALVE EXPERIENCE PILOT SUBSTUDY

Abstract

There are few studies comparing paravalvular leak (PVL) rates by valve types in patients with severe aortic stenosis following Transcatheter Aortic Valve Repair (TAVR); and none over the years. We hypothesized that self-expandable valves (SEV) were associated with a lower PVL over the years than
