Estenosis mitral con calcificación severa del anillo mitral: reemplazo mitral con prótesis OnX Conform en posición supraanular / Mitral stenosis with severe annular calcification: mitral valve replacement with an OnX Conform prosthesis in a supra annular position

ABSTRACT

Abstract 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.
