Abstract

We report a case of cardiac sarcoidosis associated with mitral valve regurgitation. A 62-year-old woman with cardiac sarcoidosis was admitted for the treatment of an intractable mitral regurgitation. She had been treated for cardiac sarcoidosis with prednisolone, and she had undergone pacemaker implantation because of advanced complete A-V block 5 years before. However, her hemodynamics deteriorated, and echocardiography revealed severe functional mitral regurgitation, thinning of the ventricular septum, and left ventricular dysfunction. The patient underwent mitral valve replacement with a mechanical prosthetic valve, and her postoperative course was uneventful. She is currently well without exacerbation of heart failure at 2 years after operation. Functional mitral regurgitation is a relatively common complication in patients with cardiac sarcoidosis. Mitral valve replacement should be considered in patients with medically intractable mitral valve dysfunction due to cardiac sarcoidosis.
