Abstract:
An 80-year-old female patient underwent redo aortic valve replacement for haemolysis caused by moderate paravalvular leakage 1 year after a 21-mm Intuity Elite valve implantation. The elevatorium passed at the segment with paravalvular leakage. The frame was then bent inward using a hook and the peel around the sawing ring was shaved by an elevatorium. After explantation of the Intuity Elite valve, endoscopic examination showed no sign of annular or sub-annular damage. Conventional aortic valve replacement using a biological valve was performed. We introduce a safe alternative technique for explantation of a rapid deployed valve.
