Abstract

Left atrial dissection is a rare complication of cardiac surgery. We present a case of left atrial dissection that occurred during a partial arch repair for Stanford acute type A aortic dissection. Because no entry was found in the left atrium by transesophageal echocardiography, and there were no issues weaning from cardiopulmonary bypass, we decided that no surgical intervention was necessary. Transthoracic echocardiography and computed tomography showed the remaining dissection on postoperative day 7; however, on postoperative day 14, it had completely disappeared.
