Balloon valvuloplasty of stenosed Carpentier-Edwards bioprosthesis at pulmonary position.

Bioprostheses frequently become calcified and stenosed, especially when implanted in younger patients. The general recommendation in such cases is to repeat surgery. Balloon valvuloplasty has hitherto been attempted with mixed success. Calcification and limitation of the balloon size due to the valve ring can lead to suboptimal long-term results. We report a case where balloon dilation of the stenosed bioprosthesis at pulmonary position was successfully performed with good immediate result. Cardiac catheterization after 3 years showed only a minimal increase (5 mmHg) in the gradient. (Indian Heart J 2004; 56: 147–149).
