Abstract

Cardiopulmonary bypass is typically required for coronary artery bypass surgery, valve repair or replacement, congenital heart defect correction and cardiovascular operation. However, difficulty in weaning from cardiopulmonary bypass can increase mortality, which makes difficulties for the physicians. The cause of difficult weaning should be found, but sometimes it is difficult. The assessment by transesophageal echocardiography plays a central role in diagnosing and managing the cardiac operations patients. The early principal goal is the assessment of any findings that indicate a structural problem, which may require immediate surgical intervention. Herein, we presented a case of difficulty in weaning from cardiopulmonary bypass. A 53-year-old woman was admitted to our hospital due to fatigue and lower limb edema. The patient planned to undergo tricuspid bioprosthetic valve replacement under cardiopulmonary bypass due to the dysfunction of the tricuspid mechanical valve and the anticoagulant drugs being ineffective. During the cardiopulmonary bypass weaning process, hemodynamic instability occurred. Abnormal tricuspid regurgitation displayed by transesophageal echocardiography. After reopening the right atrium for testing, it was found that the mitral valve was occluded by gauze. Removing the gauze from the right atrium, it was successfully separated from cardiopulmonary bypass. Transesophageal echocardiography is important to accurately understand the clinical course of such complications.
