Balloon percutaneous valvuloplasty for stenotic bioprosthetic valves in the mitral position

Percutaneous balloon valvuloplasty is useful for treatment in some patients with valvular stenosis, including those with severe calcification of the valve.^1–4 One case of dilatation of a tricuspid bioprosthetic valve was reported,⁴ but none at other positions has been reported. We report the performance and the angiohemodynamic effects of in vivo dilatation in 2 patients with stenotic bioprosthetic valves in the mitral position.
