Abstract
Background and Objectives: The risk factors are associated with surgical outcomes of cardiac surgery. This study was aimed to correlate the effect of preoperative risk factors in children with congenital heart diseases (CHDs) on the outcome of cardiac surgery. Materials and Methods: This 1-year prospective observational study was conducted in a tertiary referral hospital. A total of 200 children with congenital cardiac diseases undergoing cardiac surgery were studied pre- and post-operatively for 3 months. Results: Cyanotic and acyanotic CHDs were noted in 33% and 67%, respectively. The most common acyanotic CHD was ventricular septal defect (35%) and the common cyanotic CHD was tetralogy of Fallot (17%). Majority of the children (75.5%) presented with risk factors. 63% of the children were under risk-adjusted classification for congenital heart surgery (RACHS)-II category while 19% were in RACHS-IV. 7.5% of the children expired. Conclusion and Interpretation: Significantly high mortality was recorded in children aged
