    Abstract:
    Between 1980 and 1986, 80 infants (less than or equal to 3 months old) with symptomatic aortic coarctation and associated severe tubular hypoplasia of the transverse aortic arch underwent surgical treatment. Extended end-to-end aortic arch anastomosis was used in an attempt to correct both the isthmic stenosis and the hypoplasia of the transverse arch. After complete excision of the coarctation tissue, a long incision was made in the inferior aspect of the aortic arch, which was then anastomosed to the obliquely trimmed distal aorta. Pure coarctation was present in 17 patients (group I); 24 infants had an additional ventricular septal defect (group II), and 39 patients had associated complex heart disease (group III). The overall early mortality rate was 26% (confidence limits 21% to 32%) (18% in group I, 17% in group II, and 36% in group III). The early risk declined with time and was 18% (confidence limits 12% to 26%) for the last 2 years (seven deaths in 39 patients). Follow-up was 100% for a mean of 19 months. Actuarial survival rate at 3 years was 82% for group I, 78% for group II, and 32% for group III. Recurrent coarctation (gradient greater than or equal to 20 mm Hg) occurred in six operative survivors (10%, confidence limits 6% to 16%) and necessitated reoperation in three. Freedom from recoarctation at 4 years was 88%. Because extended end-to-end aortic arch anastomosis provides adequate correction of the aortic obstruction and entails a low risk of restenosis, it is our procedure of choice in infants with coarctation and severe hypoplasia of the aortic arch.
