Caseous calcification of mitral annulus is a rare disease characterized by tumors of the mitral cusps. Operative case reports, however, are rare because this lesion seldom negatively affects hemodynamics. We encountered a 67-year-old female case of mitral regurgitation with caseous calcification of mitral posterior annulus due to ischemic heart disease and performed mitral valve replacement and CABG. The excision of the mitral thickened lesion resulted in a defect of the mitral annulus, which needed to be repaired with an autologous pericardial patch. We mainly report the intraoperative findings of this case.
