title: Percutaneous double balloon valvotomy for bioprosthetic tricuspid stenosis.
abstract: We report two cases of percutaneous balloon valvotomy of porcine tricuspid valves and review the brief literature. Both procedures were successful, but "restenosis" resulted in tricuspid valve replacement in patient 2. The explanted valve showed leaflet thickening and calcified cuspal nodules. Patient 1 is improved 10 months later.
