RESUMO
Tetralogy of Fallot (TOF) is a congenital disorder comprised of four heart defects. It is considered a critical condition that requires surgical repair. TOF may be complicated by pulmonary valve atresia (PA) and the development of major aorticopulmonary collateral arteries (MAPCA). A 15-year-old girl from Jimma, Ethiopia, was admitted to the pediatric cardiology unit through the "Save a Child's Heart" organization. She was diagnosed at the age of four years with TOF but had not yet received treatment for the condition. Echocardiography prompted a diagnosis of TOF with PA and MAPCA. It is recommended that TOF be treated shortly after birth, thus observing this condition in 15-year-old highlights the complications that may accompany delayed repair. This report details the course of diagnosis and treatment for this patient.
