[Percutaneous balloon valvuloplasty in stenotic bioprosthetic valves]

There are only a few therapeutic indications that require implantation of bioprosthetic heart valves. To implant bioprosthesis is rare, because malfunction of the bioprosthesis occurs as a result of tissue degeneration in long-term follow up. The dysfunction is bioprosthesis insufficiency with or without stenosis. The degenerated bioprosthesis requires reimplantation, but every subsequent operation carries a higher risk. Stenotic bioprosthesis can be treated effectively by balloon valvuloplasty. The aim of the paper is to establish indications, coindications for the treatment, to present the complications and long-term follow up.
