Novel valve-in-surgical bioprosthetic transcatheter aortic valve replacement: Undermining iatrogenic coronary obstruction with radiofrequency needle (UNICORN)

Catheter Cardiovasc Interv. 2024 May;103(6):1069-1073. doi: 10.1002/ccd.31038. Epub 2024 Apr 8.

Abstract

An 86-year-old female with history of surgical aortic valve replacement presented with clinical signs of heart failure. Echocardiography revealed a reduction in left ventricular systolic function and severe bioprosthetic aortic valve dysfunction. This is the first reported case of valve-in-valve transcatheter aortic valve replacement with concomitant undermining iatrogenic coronary obstruction with radiofrequency needle procedure in a surgical bioprosthetic valve.

Keywords: bioprosthetic valve dysfunction or prosthetic valve stenosis; leaflet laceration; leaflet modification; valve‐in‐valve transcatheter aortic valve replacement.
