title: [Results of coarctectomy in newborn and young infants].
abstract: Twenty infants underwent coarctectomy between 1972 and 1979, 12 were less than one month old at surgery. One infant died after the procedure (5% mortality). Seven underwent open heart surgery later in the first year of life for associated intracardiac defects; there were 3 early and one late death. Of the 15 survivors, 12 have been followed up for 6 months to 6 years (mean 3 years). All are actually asymptomatic. Arterial blood pressure is slightly higher in the leg than in the arm in 8 patients (as in normal children), equal in leg and arm in 2 and lower in the leg than in the arm in 2 (recoarctation). Postoperative catheterization was done in six patients. A pressure gradient across the anastomotic site was confirmed in two (32 and 28 mm Hg). In the other four, no pressure gradient was found, and the site of the anastomosis was hardly or not at all detectable on the angiogram. Coarctectomy in newborns and infants now carries a low operative mortality. With proper operative technique, normal growth of the anastomotic site is usually obtained.
