Invasive and echocardiographic gradients of self- and balloon-expandable valves in failing aortic bioprostheses

Abstract Background Transcatheter aortic valve implantation (TAVI) is an established treatment for a failing aortic bioprosthesis. The hemodynamics of TAVI in degenerated transcatheter or surgical aortic valves (TAV-in-TAV or TAV-in-SAV) are unknown. We aimed to investigate hemod...
