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.
