Feasibility of Repeat TAVR After SAPIEN 3 TAVR: A Novel Classification Scheme and Pilot Angiographic Study

Transcatheter aortic valve replacement (TAVR) is expanding to younger patients, but feasibility of TAVR in failing transcatheter aortic valves (TAVs) remains unknown. We determined the feasibility of TAV-in-TAV after Edwards SAPIEN 3 (S3) (Edwards Lifesciences, Irvine, California) TAVR by evaluating
