A rare presentation of cardiac myxoma: left ventricular outflow cyst

Abstract

A 10-year-old boy presented with syncope. Echocardiography identified a freely mobile, multiple cystic tumor attached to the membranous septum of the left ventricular outflow tract underneath the right coronary sinus area (Figure 1). Transaortic excision of this cystic mass was performed (Figure 2). The postoperative course was uneventful. Histologically, the mass proved to be a cardiac myxoma.
