Abstract

Objective: To evaluate the factors affecting the early results of surgery to correct all tetralogy of Fallot in children under 1 year of age. Results: There were 115 patients with the mean age of 8.2 ± 2.7 months, the lowest was 1 month old and the highest was 12 months old. The mean aortic cross clamp (ACC) time cardiopulmonary bypass (CPB) time were 73,4 ±22,4 minutes and 99,3 ± 26,9 minutes. Z-value of the pulmonary annulus < -2, transannular patch is a factor affecting the time aortic cross clamp and cardiopulmonary bypass (CPB). Mean time of mechanical ventilation 48,4±69,1 hours, factors affecting the duration of mechanical ventilation include the group of children under 6 months of age, weighing less than 5kg, transannular patch, time aortic cross clamp more than 90 minutes and time cardiopulmonary bypass more than 120 minutes. After surgery, low cardiac output syndrome 26.1%. Factors that increase the risk of low cardiac output are  aortic cross clamp time > 90 minutes and weight < 5 kg. There was 1 death in the context of heart failure, pneumonia, sepsis. Conclusion: Total surgical repair of tetralogy of Fallot in children under 1 year of age has positive results and low mortality. Factors affecting the surgical outcome are the length of aortic cross clamp time and low weight.
