The Current Perspectives in Valve-in-Valve Transcatheter Aortic Valve Replacement

The increased use of bioprostheses in aortic valve replacement has led to increased number of patients with structural valve degeneration. Since reoperation for failed bioprostheses carries a high risk, a valve-in-valve transcatheter aortic valve replacement has become an attractive alternative treatment. However, there remains technical challenges and controversies in this field. Herein, we discuss the current perspectives in valve-in-valve transcatheter aortic valve replacement.
