OBJECTIVE: To evaluate early and late results of aortic coarctation (CoAo) surgical repair in early months of life. MATERIAL AND METHODS: Between January 1994 and May 2001, 89 patients were submitted to CoAo repair by subclavian artery flap angioplasty (Group 1 - n=49) or resection with end-to-end anastomosis (Group 2 - n=40). We analyzed and compared the mean age at operation, associated cardiac malformations, pre and postoperative aortic pressure gradient, surgical complications and mortality, and actuarial freedom from events curve. RESULTS: Most of patients were male (n=60 - 68%) and underwent to aortic repair under than one month of age, with severe heart failure (n=62 - 70%). CoAo was associated with intracardiac defects in 66 cases (74%). The aortic pressure gradient before and after surgery was 42 mmHg and 4,5 mmHg, respectively. Postoperative complications were persistent arterial hypertension (n=27), residual stenosis (n=5) and bleeding (n=3), and operative mortality was 10,2% (n=9), markedly higher in patients with associated cardiac malformations (12% vs. 4% - p<0,05). There were no differences in complications and mortality in both groups. Late re-coarctation was 16% in group 1 and 15% in group 2 (NS) and actuarial freedom from events in 60 months was 76% and 81%, respectively (NS). CONCLUSIONS: Most of surgical repair in symptomatic CoAo during early months is a life-saving procedure, due to severe heart failure; operative mortality is significant in patients with others cardiac defects; there were no differences in morbidity, mortality and recurrent coarctation rate between two surgical techniques performed.
