Overinflation of balloon-expandable valves for transcatheter treatment of pure noncalcified native aortic regurgitation: How much oversizing is needed and achievable?

Transcatheter aortic valve implantation (TAVI) in noncalcified pure aortic valve regurgitation is challenging as dedicated valves are not widely available. We present a case series of four inoperable patients who underwent compassionate TAVI for this indication at our institution with a balloon-expandable valve. In this context, we analyzed the relevant technical aspects such as the need for larger oversizing of the transcatheter prosthesis and the safety and limits of valve overexpansion.

Keywords: aortic valve disease; percutaneous intervention; transcatheter valve implantation.
