Case Report: A forty year-survivor of Tetralogy of Fallot with pulmonary atresia and chronic pediatric shunt thrombosis; findings from cardiac CT scan

Here we illustrate a rare case of Tetralogy of Fallot (TOF) with pulmonary atresia in a 40-year-old survivor patient, despite a chronic pediatric shunt thrombosis. The patient became symptomatic at 38-years-old with progressive dyspnea on exertion and short cyanosis spells. The clinical findings were unspecific except for sinus tachycardia . To reassess cardiac abnormalities and associated intrathoracic malformations, a cardiac CT-scan was performed. Here we explain the mechanism for prolonged survival as an expansion of several and huge major aortopulmonary collateral arteries. This case predicts an exceptional late outcome of untreated TOF.
