65-year-old man with a history of pulmonary emboli, atrial fibrillation, nonischemic dilated cardiomyopathy, and significant polysubstance abuse was admitted with dyspnea, new onset left-hand weakness, and a left-sided facial droop. An echocardiogram showed an estimated ejection fraction of 20% and an echogenic pedunculated mass in the left ventricle (LV) apex with minimal mobility consistent with an organized LV mural thrombus (A, Online Video 1). Low molecular weight heparin (LMWH) and warfarin were initiated; however, the patient developed a visual field deficit 9 days later. A second trial of anticoagulation therapy was attempted, and regular heparin was begun. An echocardiogram 3 days later showed a significant increase in the size and mobility of the thrombus (B, Online Videos 2 and 3). So as to avoid a potentially catastrophic embolic event, the patient underwent a thrombectomy via left ventriculotomy without complication (C).
