Short-Term Outcome of Tetralogy of Fallot Repair: A Single Center Experience    in A Developing Country

Abstract

Objective: To note short-term outcome of patients undergoing tetralogy of fallot repair. Study Design: Retrospective longitudinal study. Place and Duration of Study: Department of Pediatric Cardiology, National Institute of Cardiovascular Disease, Karachi Pakistan, from Sep 2020 to Feb 2021. Methodology: A total of 113 patients under 25 years of age who underwent tetralogy of fallot correction were included. Pre-operative information, echocardiography, investigations and history of the patient were noted. Intra-operative and post-operative information and surgical procedure were also noted. Short-term outcome included data up to discharge or death of the patients enrolled. Results: Mean age was noted to be 9.40+5.01 years, with 59(52.2%) of the patients undergoing tetralogy of fallot repair were male. Mean saturation of peripheral Oxygen (SpO2) at the time of surgery was noted to be 79.27±.34. There were 76(67.3%) patients without history of previous surgery. Mean cardiopulmonary bypass time was noted to be 106.04±40.59 minutes. Mean aortic cross-clamp time was recorded to be 58.79±27.90 minutes. Additional procedures were required in 68(60.2%) patients. Mean duration of hospital stay was 13.96±8.68 days while mean duration of ICU stay was 87.04±69.37 hours. Mortality was reported in 3(2.7%) patients. Conclusion: Low mortality and low post-operative morbidity were noted among patients undergoing tetralogy of fallot repair.
