Transcatheter heart valve implantation into degenerated bioprosthetic valves (ViV-THV implantation) has become an established procedure for high risk patients. In general, paravalvular leak (PVL) is a contraindication for valve-in-valve-TAVR (ViV-TAVR). Herein, we report on a 81-year-old patient presenting with acute heart failure for a failing aortic bioprosthesis (Medtronic Mosaic 27 mm). Intraoperative transesophageal echocardiography during urgent ViV-TAVR revealed a PVL previously not detected. After transfemoral implantation of a 26 mm-Evolut-R, balloon-fracturing of the bioprosthetic ring was performed using a 24 mm True Dilatation balloon for treatment of the PVL. Afterward, left ventricular to aortic peak-to-peak pressure gradient measured 2-4mmHg. Transesophageal echocardiography merely revealed trace PVL. Aortic root angiography showed no PVL. At discharge, echocardiography measured a transprosthetic mean gradient of 5mmHg detecting no PVL. Intentional ring-fracturing of an aortic valve prostheses may prove not only to be effective in lowering transvalvular gradients after valve-in-valve-TAVR, but may also be a tool to treat PVL alongside degenerated surgical aortic bioprostheses in certain patients.
