Supra-annular Valve-in-Valve Implantation Reduces Blood Stasis on the Transcatheter Aortic Valve Leaflets

Dr. Ali Azadani

Leaflet thrombosis following transcatheter aortic valve replacement (TAVR) and Valve-in-Valve (ViV) procedures has been increasingly recognized. This study aimed to investigate the effect of positioning of the transcatheter aortic valve (TAV) in ViV setting on the flow dynamics aspect of post-ViV thrombosis by quantifying the blood stasis in the intra-annular and supra-annular settings.
