NOVILLO, Romina et al. Mitral stenosis with severe annular calcification. Mitral valve replacement with an OnX Conform prosthesis in a supra annular position. Rev Chil Cardiol [online]. 2020, vol.39, n.2, pp.159-164. ISSN 0718-8560.  http://dx.doi.org/10.4067/S0718-85602020000200159.

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.
