[Coarctation syndrome in infancy and its outcome: surgical results and long-term follow-up].
Between 1972 and 1983, 29 newborns and infants were treated surgically for coarctation of the aorta. The mean age at operation was 2 months 7 days. 76% of the patients (22/29) had an associated intracardiac malformation, 8 requiring correction. The early mortality rate (due to coarctation repair) was 7% (2/29). The total mortality rate was 31% (7/29). Four of the 7 late deaths occurred during surgical correction of an intracardiac malformation. Twenty children were followed up for 1 to 10 years (mean 4 1/2 years) after surgery. Four patients (20%) had a recoarctation. All 4 recurrences occurred within 2 years after surgery, and in patients operated on during the first month of life. Blood pressure at the latest outpatient visit was above the 97th percentile in 6 children, 4 of whom had recoarctation. Among the patients with no evidence of recurrence, 86% had a blood pressure between the 50th and the 97th percentile or just above the 97th. Five patients underwent a maximal exercise test: none developed excessive elevation of systolic blood pressure, and no pressure difference appeared between arm and leg during the exercise test in those who had none at rest. Thus, early surgical correction improves the prognosis of infantile coarctation syndrome, but recoarctation may occur; long term follow-up is advisable.
