Adult congenital cardiac surgery in Indonesia.

Background: Successful paediatric cardiac surgery and cardiology treatment has resulted in an increase in the use of surgery as a method of treatment of congenital cardiac disease in adult population. However, late detection and lower socio-economic condition in developing countries might change patients' characteristics by the time they come for treatment. This study aimed to elaborate the long-term surgical results of adult congenital cardiac disease in Indonesia as a developing country.

Methods And Results: We reviewed retrospectively all adult congenital cardiac disease patients with a mean age of 28 years plus or minus 9.5 years, who underwent surgery at National Cardiovascular Center. The types of procedures used were corrective in 338 patients (89.2%), palliative in 10 patients (2.6%), and re-operations in 31 patients (8.2%). The overall hospital mortality rate was 2.6% but as high as 20% with palliative surgery. Post-operative New York Heart Association class III-IV is the only independent predictor of death at 60 months (hazard ratio 61.48, 95% confidence interval 9.41-401.69, p<0.001). The survival rates were 96.3% and 95% for overall and non-atrial septal defect in patients at 60 months, which was highest in corrective procedures (97.6%). The percentage of patients free of re-operation at 5 years' follow-up was 85.4% and 42.7% at 10 years.

Conclusion: In developing countries, surgical treatment of adult congenital cardiac disease is effective and safe, with an overall survival rate of 96.3% at 60 months. Due to high mortality rate, palliative surgery of a non-atrial septal defect patient is recommended to be discontinued. The independent predictor of mortality was post-operative New York Heart Association functional class III-IV.
