A 34-year-old man visited our institution for an abnormal chest radiograph with greatly enlarged cardiac silhouette (Panel A) found before his wedding. Detailed medical history revealed a febrile episode and a strawberry-like tongue and some flu-like symptoms for >1 week when he was 5 years old. Diagnostic workup including computerized tomography demonstrated a huge right coronary artery aneurysm (Panel B). Intra-operative transesophageal echocardiography showed a large orifice of right coronary artery with a huge aneurysm (Panel C). The right coronary artery aneurysm was resected (Panel D) under hypothermic cardiopulmonary bypass with cardioplegic arrest. The diameter of the orifice of the right coronary artery was >20 mm, which was closed with Dacron patch, and the saphenous vein was used to bypass the right coronary artery to its two major branches. The patient had an uneventful recovery and was discharged 6 days after the operation.
Panel A. Chest X-ray shows an enlarged cardiac silhouette.
Panel B. Thorax CT-scan shows the right coronary artery aneurysm (white arrows) and its connection (black arrow) with the aorta. MPA, main pulmonary artery.
