Double-balloon valvuloplasty of calcified bioprosthetic pulmonary valve twenty-three years after implantation.

Balloon valvuloplasty to dilate stenotic bioprosthetic valves is rarely used, but has been applied successfully to dilate bioprosthetic mitral, aortic, tricuspid and, to a lesser extent, pulmonary valves. The case is reported of a 45-year-old male patient with right-sided heart failure who underwent a successful dilatation of a stenotic, calcific bioprosthetic pulmonary valve using double-balloon valvuloplasty.
