[Mitral valve myxoma that was resected with valve plasty].

Cardiac myxomas arising from the mitral valve are extremely rare. We describe the case of an asymptomatic 47-year-old male patient with a myxoma measuring 11 mm in diameter originating from the anterior leaflet of the mitral valve as observed by transthoracic echocardiography. The tumor was excised, and a defect in the anterior leaflet of the mitral valve was patched with autologous pericardium. Mitral valve regurgitation was observed and partial annuloplasty was performed. Following this, mitral valve regurgitation was observed to be diminished.
