title: Interrupted aortic arch in infancy: a 10-year experience.
abstract: Fifty infants with interrupted aortic arch (IAA), admitted between 1979 and 1988, were reviewed. They usually presented early in severe cardiac failure or shock. In the initial 5-year period, 17 of the 21 infants underwent diagnostic or confirmatory cardiac catheterization, in contrast with the latter 5 years when only eight of the subsequent 29 patients underwent catheterization. Since 1987, all patients underwent surgery after cross-sectional echocardiography. Fifteen infants had a type A IAA and 35 had type B. All had associated cardiac anomalies. Four infants were not operated on. In the initial 5-year period, of 17 infants who were surgically treated, four had a one-stage total repair, the remaining had a two-stage repair with initial reconstruction of the arch and pulmonary artery banding. There was an overall surgical mortality of 65%, reflecting the precarious state of many of these infants before surgery with a significant contribution from unrelieved subaortic stenosis. In the latter 5-year period, 29 underwent surgery, 22 had a one-stage total repair. There were three deaths, all in infants whose active treatment was withdrawn. The outcome of the survivors has generally been good, subsequent surgery being mainly related to the associated anomalies (e.g., recurrent subaortic stenosis, conduit replacement). Over this 10 year period the greater accuracy of noninvasive diagnoses, and perioperative intensive care, have led to an improvement in the preoperative state of these infants. Single-stage total repair is our procedure of choice.
