Operative repair of coarctation of the aorta in infancy: results with and without ventricular septal defect.
Coarctation of the aorta (CA) presenting in infancy is a life-threatening condition, especially if associated with intracardiac left-to-right shunts. Between 1971 and 1980, 51 infants with symptomatic CA have been diagnosed and treated. Ventricular septal defect (VSD) was present in 18 patients and patent ductus arteriosus in 24. End-to-end repair was performed in 20 patients, 17 (85%) of whom were long-term survivors. Subclavian flap angioplasty repair was used in 28 patients, of whom 25 (89%) were long-term survivors. During long-term follow-up 6 patients (35%) who underwent end-to-end repair had recurrent CA, whereas only 3 patients (12%) who underwent subclavian flap angioplasty had recurrent CA (p less than 0.05). The mortality rate in patients with associated VSD was higher (4 of 18, 22%). Pulmonary trunk banding with subsequent VSD repair was associated with a better survival (13 of 14 patients, 90%) than when banding was not performed (2 of 5 patients) (p less than 0.05). These results suggest subclavian flap angioplasty is the preferred treatment for symptomatic CA occurring in infancy. Concomitant pulmonary trunk banding in patients with VSD can be performed with the expectation of a lower mortality at subsequent VSD repair.
