In the past years a substantial shift away from mechanical heart valves occurred and bioprosthetic heart valves claimed majority of market shares irrespective of patients' age.This indicates that population with failed surgical bioprostheses requiring ViV-TAVI will grow significantly and therefore, meticulous prospective data collection is necessary for future analyses in order to better understand potential limitations of this procedure.


The study is a prospective multicenter evaluation of transcatheter aortic valve-in-valve implantations in Polish health centers.

Duration of this study is expected to be 6 years to ensure that all of the enrolled patients will complete at least 2 years of follow-up.
