Estenosis mitral con calcificación severa del anillo mitral. Reemplazo mitral con prótesis OnX Conform en posición supraanular

Abstract

Mitral stenosis with severe annular calcification. Mitral valve replacement with an OnX Conform prosthesis in a supra annular position. A 68-year-old man previously subjected to radiotherapy had a prior aortic valve replacement due de radiation induced calcification of the aortic valve. Presently the patient developed severe calcification of the mitral valve ring leading to critical mitral valve stenosis. A supra annular implantation of an On X Conform valve was successfully achieved. The clinical course was uneventful, and the echocardiographic evaluation demonstrated a normal function of the valve. Different alternatives for the surgical management of this complication are discussed.
