Stroke after intraaortic balloon counterpulsation associated with mobile atheroma in thoracic aorta diagnosed using transesophageal echocardiography.

We describe a patient who developed embolic stroke after coronary artery bypass grafting (CABG) associated with intraaortic balloon pump (IABP) insertion. Intraoperative transesophageal echocardiography (TEE) revealed marked irregular mass and disruption of the intimal surface of the thoracic aorta with overlying shaggy echogenic material on the intimal surface of the descending thoracic aortic lumen. This case of stroke after IABP insertion suggested that the balloon inflation fragmented some mobile components on the inner surface of the aorta, and this floating debris entered the systemic circulation. TEE might be able to predict the risk of stroke in such a patient. (Chang Gung Med J 2002; 25:612-6)
