Emergent pulmonary thromboembolectomy and atrial septal aneurysmectomy for intracardiac impending paradoxical embolism: An en bloc approach to prevent clot embolism and facilitate repair.

Abstract

Although a patent foramen ovale (PFO) is relatively common, confirmed reports of thrombus entrapped within a PFO are uncommon. Management of impending paradoxical embolism (IPE), also called a thrombus in transit, lacks consensus but includes systemic anticoagulation (e.g., heparin), systemic thrombolysis, or surgical thrombectomy. We present a case of IPE diagnosed with intraoperative transesophageal echocardiography (TEE) as well as a novel en bloc approach to atrial septal aneurysmectomy to minimize embolism and facilitate repair of the interatrial septum. Timely use of intraoperative TEE may aid in diagnosis and help guide the surgical approach to minimize embolic risk with an IPE.
