Early Surgical Outcome for Tetralogy of Fallot in an African Setting; A Tanzanian Experience Using Retrospective Analysis of Hospital Data

Tetralogy of Fallot (TOF) is typically treated in infancy but often done late in many resource-limited countries, jeopardizing surgical outcomes. This study examined the early results of children undergoing primary complete TOF repair at the Jakaya Kikwete Cardiac Institute (JKCI) in Tanzania, an emerging cardiac center in Eastern Africa. A retrospective cohort study of children ≤ 18 years undergoing primary TOF complete repair between 2019 and 2021 was conducted. Patients with complex TOF and those with obvious genetic syndrome were excluded. Data on socio-demography, pre-and postoperative cardiac complications, Intensive Care Unit (ICU) and hospital stay, and in-hospital and 30-day mortality were analyzed. Logistic regressions were employed to find the factors for mortality, ICU, and hospital stays. The I02 children underwent primary TOF complete repair were majority male (65.7
