Association of Implantation Depth With Hemodynamics and Mechanical Consequences in Small Valve-In-Valve TAVR
Background Valve-in-valve (ViV) transcatheter aortic valve replacement in small surgical bioprostheses is often limited by residual gradients and prosthesis-patient mismatch. Implantation depth is operator-controlled, but depth guidance for different valve combinations remains limited. Objectives The authors aimed to e...
