Aortic valve replacement for paraprosthetic leak after transcatheter implantation.

Author information

Cardiac Surgery Unit, Istituto Clinico Humanitas IRCCS, Rozzano, Italy.


Conversion to surgical aortic valve replacement (AVR) has been described as a complication following transcatheter aortic valve implantation. This complication occurs in up to 8% of cases and, to the best of our knowledge, preoperative data and surgical outcomes of such patients have not been properly evaluated. Mild paraprosthetic regurgitation is commonly observed after transcatheter aortic valve implantation and usually leads to a benign clinical course. Unequal distribution of valve calcifications is described as a potential mechanism. We report a case of a perioperative paraprosthetic regurgitation that underwent successful urgent surgical AVR and review the incidence and results of paraprosthetic leaks following transcatheter implantation.
