Unusual cause of an ejection murmur: myxoma in the left ventricular outflow tract.

We present the case of a healthy, asymptomatic 50-year-old woman with a systolic ejection murmur who was found to have an obstructive left ventricular outflow tract mass. Transthoracic echocardiography revealed a large mobile mass attached to the basal anterior septum of the left ventricle. Surgical resection was performed and a benign left ventricular outflow tract myxoma was diagnosed. The patient's postoperative course was unremarkable. We describe the clinical presentation and role of 2- and 3-dimensional transthoracic and transesophageal echocardiography in surgical management.
