title: Diagnosis by intraoperative transesophageal echocardiography of acute thrombosis of mechanical aortic valve prosthesis associated with the use of biological glue.
abstract: Mechanical aortic valve thrombosis is an uncommon complication of valve replacement. Inadequate anticoagulation is observed in 45% of patients presenting with this complication and it occurs as close as 15 days postoperation (1). Failure to wean from cardiopulmonary bypass (CPB) after aortic valve replacement may be because of a multitude of pathologies. We present a case where easy access to transesophageal echocardiography (TEE) allowed a rapid diagnosis of acute mechanical aortic valve occlusion with subsequent successful surgical management.
