Abstract
Tetralogy of Fallot (TOF) is the leading cyanotic congenital heart disease. We commenced open-heart surgery at the Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife, Nigeria in 2016. To review the incidence, pattern, management and treatment outcomes of TOF at the OAUTHC. A retrospective audit was undertaken of hospital records, including echocardiograms of patients with TOF seen from January 2016 to February 2020 at the Paediatric Cardiology Unit, OAUTHC. Seventy-two patients (37 boys and 35 girls) aged 0.17-22 years had TOF. Thirty-three (45.8%) had surgery; 31 (93.9%) corrective surgery and two (6.1%) a modified Blalock-Taussig shunt. Complications following surgery included cardiac dysfunction, post-transfusion malaria, pulmonary regurgitation, pericardial effusion and death (15%). Thirty-nine (54.2%) patients had conservative medical management. Complications included polycythaemia and thrombotic stroke, and 14 (35.9%) patients died. TOF is associated with significant morbidity and mortality in developing countries. Early and safe corrective surgery is desirable.
