Description

<p>　A 67-year-old man underwent surgery for combined valvular disease. We did not identify the coronary sinus on transesophageal echocardiography (TEE) performed before cardiopulmonary bypass. Intraoperatively, following the insertion of a cannula for retrograde cardioplegia, we observed coronary sinus orifice atresia together with an unroofed coronary sinus. Preoperative contrast-enhanced computed tomography (CT) revealed that the coronary sinus opened into the left atrium. We cut the left atrium to insert the cannula for retrograde cardioplegia, and successfully performed cardioplegic perfusion. We did not modify the surgical procedure and did not repair the coronary sinus because we did not detect any other cardiovascular deformities. TEE performed after cardiopulmonary bypass revealed that the coronary sinus opened into the left atrium. However, it did not significantly affect the method and convalescence from the disorder. This case report highlights the importance of accurate preoperative CT and perioperative TEE.</p>
