A Mitral Valve Myxoma: Case Report

Myxoma is the most common type of primary tumors of the heart. It is a rare tumor with an estimated incidence of 0.5 per million population per year. Most cardiac myxomas originate in the atrial septum in the area of the fossa ovalis and 75% occur in the left atrium. Valvular myxomas are very rare: the tricuspid valve is the most frequently involved location, followed by the mitral, pulmonic, and aortic valves. Our case was a 24-year-old male with mitral valve myxoma and a history of progressive dyspnea. After diagnosis was confirmed by 2-dimensional echocardiography, he underwent cardiac surgery, the tumor was successfully excised from the posterior leaflet of the mitral valve, and the mitral valve defect was repaired with direct suture (Iranian Heart Journal 2006; 7 (2):44-47).
