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. © 2017,professional medical publications. all rights reserved.
