A 75-year-old female with a history of rheumatic heart disease was admitted due to a syncopal episode. During the past 2 months, she reported 2 other sudden, brief episodes of syncope consistent with drop attacks. There were no premonitory symptoms suggestive of vasovagal syncope. Physical examination demonstrated an irregular rhythm and an apical diastolic murmur. Telemetry demonstrated her rhythm to be atrial fibrillation with a controlled rate. Electroencephalogram did not demonstrate seizure activity. Transesophageal echocardiography demonstrated severe mitral stenosis with a 5 x 5 cm, free-floating, left atrial thrombus intermittently obstructing the mitral valve orifice, which was bouncing off the mitral valve much like a pinball. These findings were confirmed on transesophageal echocardiography (Figures 1-4 and Video 1). The patient underwent removal of the thrombus along with mitral valve replacement, and was placed on chronic anticoagulation. She did not have any further syncopal episodes at 1-year follow-up exam.
