Abstract
Impending paradoxical embolism is a rare but potentially life-threatening complication of venous thromboembolism that is usually associated with acute pulmonary embolism and a right to left atrial shunt. Patients may have associated right ventricular pressure or volume overload with subsequent failure. Transesophageal echocardiography is the preferred diagnostic test of choice in this patient group. Definitive management has yet to be clearly defined. However, emergent surgical removal of the entrapped intracardiac blood thrombus may be necessary. In this article, we review a case of impending paradoxical embolism managed surgically and describe the perioperative anesthetic considerations in this patient population, along with the role of intraoperative transesophageal echocardiography.
