Giant Left Atrial Thrombus Successfully Treated with Anticoagulation

A giant left atrial mass (6 cm × 4 cm) was visualised on a transoesophageal echocardiogram in an elderly woman who had a history of nonvalvular atrial fibrillation. The surgical removal of the mass, presumed to be a thrombus, was declined by the patient, and oral anticoagulation with warfarin was initiated. After eight weeks of anticoagulation, a repeat echocardiogram demonstrated complete resolution of the mass, without systemic embolisation.
