Progressive narrowing at the entrance and exit of coronary artery aneurysm can develop at late phase of Kawasaki disease (KD). Evaluation and prediction of progressive coronary lesions remain a challenge in the treatment of post-KD coronary artery disease. We aimed to elucidate long-standing issues imposed on the patients who underwent coronary artry bypass grafting (CABG) for coronary artery lesions associated with KD. Between January, 2000 and December, 2013, CABG for coronary artery lesions associated with KD were performed in 6 patients (male/female: 5/1, mean age 14.5±10.0). There was no operative mortality. Follow-up for the 6 patients has been performed with the average period of 5 years (1~9 years). Cardiac events occurred in 2 patients during follow-up. In 1 patient, left internal thoracic artery (LITA) occluded due to flow competition between the native artery and LITA graft after LITA to LAD bypass grafting. The other patient required a re-do CABG using the free right internal thoracic artery to the circumflex branch because of occlusion at the coronary artery aneurysms after 4 years postoperatively. Meticulous preoperative diagnostic evaluations of coronary artery aneurysm may further improve the long-term outcome after surgical intervention for coronary lesions in conjunction with an aneurysm.
