ABSTRACT
A 70-year-old man received a mitral valve replacement (MVR) using a Mosaic valve for mitral regurgitation with valve tethering due to ischemic cardiomyopathy a year previously. Echocardiogram demonstrated mitral prosthetic valve regurgitation due to fixed leaflet 6 months ago. Despite medical treatment, he complained of dyspnea and renal function worsened. Therefore, he underwent re-MVR in the first year of MVR. We replaced the mitral valve with mechanical valve via right thoracotomy. Severe pannus growth was found in a non-coronary cusp corresponding to the posterior leaflet of the mitral valve. The bioprosthetic valve leaflet was folded and compacted by the pannus that covered the outflow surface of the leaflet.
