Correction of aortic coarctation in neonates: mortality and late results.

To determine those factors that affect mortality and to analyze long-term results, the records of 44 infants who underwent repair of aortic coarctation at less than 90 days of age were examined. There were 14 operative and 8 late deathes (mean, 4.3 months postoperatively). Subsequent operation, generally to repair or palliate associated anomalies, was required 22 times in 20 patients and was a source of considerable mortality. There is evidence that earlier total repair of associated anomalies might improve survival. Sufficient data were available on 17 of the 22 survivors to assess long-term results. The outcome was considered excellent in 8 patients, fair in 4, and poor in 5. Revision of the coarctation repair due to growth failure of the anastomosis was required in 1 patient. Aggressive surgical management is recommended in these infants because, despite a high early mortality, a considerable proportion of excellent results can be anticipated in what is otherwise a hopeless situation.
