Tetralogy of Fallot in the nascent open-heart surgical era in a tertiary hospital in south-west Nigeria: lessons learnt
Open accessAbstract
BACKGROUND: 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. OBJECTIVES: To review the incidence, pattern, management and treatment outcomes of TOF at the OAUTHC. METHODS: 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. RESULTS: 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. CONCLUSIONS: TOF is associated with significant morbidity and mortality in developing countries. Early and safe corrective surgery is desirable.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
