Tetralogy of Fallot repair in patients presenting after Infancy: A single surgeon experience
Objective: To determine the early surgical outcomes of Tetralogy of Fallot (TOF) repair in children and young adults operated after the age of one year.
Methods: In this retrospective study, 307 cases of primary repair of Tetralogy of Fallot were done between September 2012 to February 2017, at CPE Institute of cardiology, Multan. Out of 307 operated patients, 4 (1.3%) patients had previous modified Blalock Taussig shunts, 2 (0.6%) associated ASD with TOF, 3 (0.9%) co-association of TOF with PDA, 2 (0.6%) had large conal arterial branch crossing the annulus, 3 (0.9%) had dextrocardia with situs inversus, 12 (3.9%) TOF with double outlet right ventricle (DORV), 2 (0.6%) were associated with complete AV canal defect, 8 (2.60%) with absent pulmonary valve syndrome, 15 (5.5%) with left pulmonary artery stenosis. Data of post-operative complications and operative parameters was recorded for all patients.
Results: Mean age of operated patients was 9.56±4.89 years. Post-operative complications occurred in 7.8% of patients. Most common post-operative complications were pleural effusion with a frequency of 12(3.9%) patients, and complete heart block in one patient. Insignificant small residual VSD was diagnosed in 8 (2.6%) patients. One moderately large VSD was closed surgically after one year of 1st surgery. Moderate to severe pulmonary valve regurgitation was diagnosed in 114 (37.1%) patients. Mild to moderate tricuspid regurgitation in 15 (4.8%) patients and moderate right ventricular outflow tract obstruction (RVOT) in 16 (5.2%) patients. Thirty-day mortality was only four (1.3%).
Conclusion: Surgical correction of Tetralogy of Fallot (TOF) in children after one year carries good operative outcomes with minimum morbidity and mortality.
