Abstract

Background: A novel pressure-regulated deployment method for balloon-expandable transcatheter heart valves (THVs) has been developed(1) to improve clinical outcomes by regulating maximal annular wall tension during prosthesis expansion – to both optimise prosthesis-annulus apposition and diminish annular injury. The previous feasibility study(1) showed that THV deployment at wall tensions between 3-3.5 MPa may be associated with reduced paravalvular-leak (PVL) severity and avoidance of annular rupture.
