A Case of Iatrogenic Chordal Rupture after Transcatheter Aortic Valve Implantation Procedure Requiring a Second Valve.

Transcatheter aortic valve implantation (TAVI) has emerged as a therapeutic option for high-risk aortic stenosis. Malposition of the prosthesis and severe residual aortic regurgitation are known complications of the procedure, which might require a second valve implantation. Although the implantation of a second valve seems to be an effective method, very few data are available describing this technique. Herein is reported a case of iatrogenic chordal rupture in a TAVI procedure which required a second valve implantation due to dislodgment of the first prosthesis.
