Key result
Surgical removal of an embolized left ventricular thrombus from the abdominal aorta using Fogarty catheters under deep hypothermic circulatory arrest was successful in a 1-year-old girl.
Case Report (n=1)
Intraoperative whole body angiography under low-flow cardiopulmonary bypass can successfully locate and guide the removal of a migrated left ventricular thrombus in a pediatric patient.
A 1-year-old girl with severe left ventricular dysfunction presented with large floating thrombi in the left ventricle. Surgical thrombectomy was urgently required. During cannulation, transesophageal echocardiogram detected that the thrombus had vanished from the left ventricle. Whole body angiogram under very low-flow cardiopulmonary bypass successfully obtained the exact site of embolization with reducing total amount of contrast media in the operating room. Consequently, under deep hypothermic circulatory arrest, the obstructive thrombi at the abdominal aorta were successfully removed using Fogarty catheters from ascending aortotomy. Although delayed sternal closure was postoperatively required, no complication including thromboembolic events were observed for a 1.5-year follow-up period.

Nagashima et al. (2009) conducted a case report in Severe left ventricular dysfunction with left ventricular thrombus and abdominal aortic embolism (n=1). Surgical thrombectomy with whole body angiogram and Fogarty catheter removal was evaluated on Complications including thromboembolic events. Surgical removal of an embolized left ventricular thrombus from the abdominal aorta using Fogarty catheters under deep hypothermic circulatory arrest was successful in a 1-year-old girl.
