"Hanging by a thread" left ventricular thrombus in an asymptomatic soldier.

A mobile and pedunculated left ventricular mass was incidentally detected on transthoracic echocardiography in a 32-year old asymptomatic soldier. Because of the mobility of the mass and the uncertainty of its nature, the risk of embolization was considered to be high, and hence surgical removal was recommended but the patient opted for anticoagulation therapy. The mass resolved within 6 weeks without any embolic or bleeding complications. No recurrence of the thrombus was observed during a 12-month follow up period.
