Introduction: Along with advances occurring in cardiopulmonary bypass (CPB) including improved anesthesia intubation and early surgical interventions, it has become possible to correct life-threatening congenital heart anatomic abnormalities in patients. Our study aimed to collect information from one of the most important centers of pediatric cardiac surgery in Iran since there is limited information in this field in our country.

Methods: In this study, the results of  pediatric cardiac surgery and mortality were studied for two years. A retrospective, descriptive study was carried out on 789 patients   within two years. 401cases were excluded as they had congenital heart disease complexity. The patients were referred from other pediatric cardiac medical centers. Information related to kinds of surgical operation and deaths were collected from patients' documents and questionnaire. The data were analyzed by descriptive statistical tests in SPSS version-16.

Results: The age range of patients varied from three days to 18 years. The male/female ratio was 53.4%. CPB was not applied for 21.1% of patients. The frequency of operations included PDA (Patent Ductus Arteriosous) [D&L] (%8.5), total correction for TF (Tetralogy of Fallot) (%16.7), systemic to pulmonary shunt (%26.5), ASD (Atrial Septal Defect) and VSD (Ventricular Septal Defect) closure (%5.4) and (%28), respectively as well as coarctationrepaire (%14.6). Total mortality rate was 8.6%. Analysis of the operated population showed that outcome of patients has improved in recent years.

Conclusions: Compared with other studies, the results of our investigation showed that children's congenital heart surgery is on the rise.
