심방 중격과 승모판 전엽 양쪽에 동시에 부착된 좌심방 점액종 1예

Abstract

Myxoma is the most common primary cardiac tumor. It usually develops on the interatrial septum, and occurs in the left atrium in more than 75% of cases. Myxoma in the ventricle is much less common and aceunts for only 5% of cases. A myxoma arising from mitral valve is exceedingly rare and is normally located on the atrial side of valve, with an eqivalent distribution between the anterior and posterior leaflets. We report a case of myxoma that arose from both the interatrial septum and anterior coital leaflet, which has not been previously reported in the I iterature.
