RESUMO
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.

Mitral valve replacement with preservation of chordae tendineae and papillary muscles is a well-known technique which has proved beneficial by reducing postoperative left ventricular remodeling and preserving left ventricular function. This advantage has been demonstrated in functional mitral valve regurgitation as well as mitral valve regurgitation due to rheumatic disease. Regarding complications of this technique, several of them have been reported, papillary muscle rupture being one of them. We describe a clinical case of this weird but possible kind of complication.
