Anaesthetic considerations in a patient with right heart thrombi-in-transit.

Abstract

This is a case report of a patient with underlying pulmonary thromboembolism who was diagnosed as having a large, mobile right heart thrombi while undergoing treatment with low-molecular weight heparin. She underwent emergency embolectomy with exploration of the right heart under a cardiopulmonary bypass (CPB). Soon after induction of anaesthesia, the patient had an episode of severe hypotension, which responded to inotropes. Large, serpiginous thrombi were found in the right atrium extending into the right ventricle and pulmonary arteries, which were evacuated. She was weaned off CPB on inotropic support and was extubated uneventfully on the 4th POD. Postoperatively, she was started on anticoagulant therapy and also underwent placement of a Greenfield inferior vena caval (IVC) filter to prevent further thromboembolic episodes.
