[Surgical treatment of coarctation of the aorta in the infant less than a year old].

Between 1972 and 1984, 141 infants of less than 12 months of age were operated upon for coarctation of the aorta. The abnormality was isolated in 41 cases (29 p. 100) and associated with ventricular septal defect (VSD) in 58 cases (41 p. 100), with transposition of the great vessels with or without VSD in 16 cases (11.3 p. 100), with cardiac valve disease with or without VSD in 11 cases (7.8 p. 100) or with miscellaneous intracardiac lesions in 15 cases (10.6 p. 100). Resection-anastomosis (Crafoord) was performed in 89 cases (63 p. 100), subclavian flap aortoplasty (Waldhausen) in 36 cases (26 p. 100) and dacron aortoplasty in 16 cases (11 p. 100). Cerclage of the pulmonary artery was combined with one or another of these operations in 65 cases (46 p. 100). Twenty-five patients (17.5 p. 100) died within 30 days of the operation, and 28 patients (24.7 p. 100 of those who survived surgery) died at a later stage. Three infants were lost sight of. Follow-ups ranged from 1 to 13 years (mean: 4.01 years). Fifteen infants (13.3 p. 100 of those who survived surgery) were reoperated upon for recurrence of the coarctation. Four infants (3.5 p. 100) now present with clinical signs of recoarctation and are awaiting treatment.
