Abstract
|
|
|
|
A 77-year-old woman was scheduled for a coronary artery bypass graft. Her preoperative transthoracic echocardiographic (TTE) examination revealed an enlarged left atrium with reduced systolic dysfunction (ejection fraction: 38%), moderate global hypokinesia of the left ventricle, and moderate mitral and tricuspid regurgitation. No thrombus was visualized on the preoperative TTE. However, the intraoperative transesophageal echocardiography performed before the cardiopulmonary bypass revealed a thrombus of approximately 1.3 × 1.8 cm in the left atrial appendage (LAA). The LAA thrombus was removed, an internal suture was placed on the LAA before the coronary artery bypass grafting, and the main operation was performed successfully. The patient was transferred to the intensive care unit to receive postoperative care. She was extubated 4 h after the surgery and was transferred to the general ward on postoperative day 3 without any neurological sequelae.
