Manufacturer was informed of the following event through publication "a case of a transcatheter valve-in-valve implantation using balloon expandable valve for failed solo smart stentless bioprosthetic valve" by tamura h.Et.Al.Reportedly, a patient who had undergone surgical aortic valve replacement with the solo smart stentless bioprosthetic valve 25 mm and mitral valve replacement with mosaic 29 mm 4 years ago, was diagnosed with congestive heart failure.Echocardiography revealed severe aortic regurgitation caused by degraded bioprosthetic valve.As reported, patient required continuous dobutamine administration to maintain hemodynamics.It was decided to perform transcatheter valve-in-valve implantation (viv-tavi) using balloon expandable valve (edwards sapien 3).Since solo smart stentless valve was placed to valsalva sinus at the supra-annular level with continuous sutures, it was planned to anchor tavi valve 4 mm to the left ventricular side from the bottom of the failed stentless valve.Two pigtail catheters were placed at the bottom of the failed stentless valve leaflet to mark the nadir of stentless valve.After viv-tavi, the patient no longer required catecholamine administration and was discharged home one month later.
