Background-We surveyed the national experience of coronary artery bypass grafting (CABG) for coronary sequelae of Kawasaki disease (kDa) in 2002. Methods and Results-A questionnaire was returned from 323/552 (59%) institutions. Two hundred forty-four patients (188 male 56 female) since 1975 were identified. The mean number of grafts was 1.8 and the age at operation ranged from 1 to 44 years (median 11 years). The interval from the onset of kDa to operation ranged from 1 month to 42 years (median 8 years), whereas the follow-up period was from 7 days to 25 years (median 5 years). Previous myocardial infarction was found in 70 patients (28%). When the age at operation was older than 12 years, patency rates for internal thoracic artery grafts (ITA) at 1, 5, and 15 years were 95%, 91%, and 91%, respectively (nϭ156). When the age at operation was younger than 12 years, the corresponding values were significantly lower, with 1, 5, and 15 years being 93%, 73%, and 65%, respectively (nϭ146) (PϽ0.05). Reoperation was performed in 14 patients (6%
