![]() Primary repair of interrupted aortic arch and coarctation plus hypoplastic arch compares favorably with a staged approach and is recommended even when complex intracardiac anatomy is present. An infant with an interrupted aortic arch needs heart. This part of the blood vessel is vital because it helps send oxygenated blood to the lower part of the body. It occurs when the curved arch-shaped section of the aorta (an important blood vessel) doesn't completely form. Actuarial freedom from recurrent arch obstruction was 69% (confidence limits 48% to 85%) at 46 months' follow-up. An interrupted aortic arch is a very rare congenital heart condition. This should not be confused with an interrupted aortic. Actuarial survival was 75% (confidence limits 65% to 83%) at 12 months, with no subsequent deaths over 1294 patient-months (mean 28 months) of follow-up. The subclavian artery is reconstituted from either the vertebral artery or the ductus arteriosus (36). The mortality in the isolated myocardial perfusion group was 0% (confidence limits 0% to 14%), which may be related to reduced myocardial ischemic time (p less than 0.05). For arch repair plus biventricular intracardiac repair, the operative mortality was 9% (confidence limits 5% to 15%), and for arch repair plus palliative intracardiac repair, 40% (confidence limits 22% to 60%). The operative mortality overall was 14.5% (confidence limits 10% to 22%). A complete intracardiac (biventricular) repair was performed except in patients expected to require a Fontan operation as definitive treatment. When severe, SAO must be addressed in surgical. Isolated myocardial perfusion was used in 13 patients during arch repair. Abstract Interrupted aortic arch (IAA) is often related developmentally to subaortic obstruction (SAO). All operations were performed via sternotomy with core cooling and circulatory arrest. All patients had significant congestive cardiac failure, and the majority required prostaglandin E1 resuscitation and inotropic support (with or without ventilation) before the operation. Associated severe intracardiac anomalies were the rule. ![]() ![]() Median age at operation was 6 days and median weight 3.1 kg. Herein we describe our experience with repair of interrupted aortic arch and coarctation plus hypoplastic aortic arch in 55 consecutive infants (1984 to 1990). ![]()
