OBJECTIVE: To report the institution experience with the surgical treatment of adults with congenital heart disease due to the increasing number of these patients and the need for a better discussion of the subject. METHODS: Retrospective analysis describing demographic data, risk factors and results. RESULTS: 191 patients between 16 and 74 years old were operated on. Primary correction was done in 171 cases, 93 (55%) for atrial septal defect repair. Among 20 (12%) reoperations, pulmonary valve replacement was done in six cases. The mean intensive care and hospital stay were 2.7 and 8.5 days respectively, significantly greater for the reoperated cases (P=0.001). The mean bypass and clamping times were 68.6 and 44.7 minutes respectively, greater for the reoperated cases (P<0.0001 and P=0.0003 respectively). Hospital mortality was 4.2% and male sex, functional class III-IV and older age at operation were predictive risk factors. Significant complications were more frequent in the reoperated cases (P<0.003), mainly atrial flutter and fibrillation. Among 183 patients discharged, 149 (82%) are being followed and atrial flutter and fibrillation are common. The mean functional class value improved significantly after operation (1.66 to 1.11; P<0.0001). The estimated survival was 96.2% in six years. CONCLUSION: Heart surgery in adults with congenital heart disease can be accomplished with low mortality and functional class improvement. Immediate and late complications are frequent. Multicenter studies are important to better characterize this patient population in the country.
