Modified Myers and coronary artery bypass grafting using free internal thoracic artery graft for complicated supravalvular aortic stenosis.

The left main trunk stenosis with Williams syndrome and supravalvular stenosis is a cause of sudden death and a serious disease. We performed modified Myers procedure with patch aortoplasty concomitant with coronary artery bypass grafting (CABG) using a free right internal thoracic artery (ITA) graft for a 2-year-old patient with this disease. The proximal cuff of the free right ITA graft was implanted in the posterior wall of the reconstructed aorta. The postoperative clinical course was uneventful, and aortic regurgitation and ischemic signs were not detected. CABG using this technique is useful for coronary artery stenosis in infants and young children, and favorable long-term outcomes are expected.
