Left ventricular thrombus with a normal heart.

A 44-year-old man was found to have a left ventricular mass by transthoracic echocardiography. He had had multiple events of systemic embolization over the last few years. The heart was not dilated, and heart function was normal. Surgical excision was recommended to avoid further embolization. A transverse aortotomy was carried out under cardioplegic cardiac arrest with standard cardiopulmonary bypass. A transaortic video-assisted endoscopic procedure was performed. The mass was resected endoscopically without left ventriculotomy. Pathologically, the excised mass was an organized thrombus with a fibrous stalk connected to endocardium. We thus report a case of left ventricular thrombus with a normally functioning heart.
