Abstract

Introduction: Since 1954, after the first surgical repair of tetralogy of Fallot (TOF), several innovations have occurred in cardiac surgery, especially in children. One stage complete repair of TOF is currently possible even in infancy; however, complications such as hypoxemia, arrhythmia, cardiac dysfunction, sudden death, and valvular disorders may happen. In this study, we evaluated the results of complete surgical repair of TOF with pulmonary stenosis.
Material and Methods: We assessed 74 cases of TOF with pulmonary stenosis that underwent surgery in Cardiac Surgical Ward of Imam Reza Hospital, Mashhad, Iran from 2008 to 2010.
Results: Mean age was 5.74±3.31 years and more than half of the patients were male. Mean perfusion and cross-clamping times were 55.45±15.06 and 42.63±9.07 min,respectively. The most common coexisting anomaly was atrial septal defect. Further, 83.7% of the patients were symptomatic, and history of spell attacks was positive in 24.3% of the cases. Arrhythmia was reported in 28.4% of the patients. Mortality rate was 12.2% in our study, which was higher in younger patients (P=0.022) or those with lower weight (P=0.008), longer perfusion time during cardiac surgery (P=0.009), or presence of associated cardiac anomalies (P=0.030).
Conclusion: Outcomes and mortality rate of one-stage surgical repair of TOF with pulmonary stenosis was acceptable in our center, and arrhythmia was the most common postoperative complication
