We describe 5 adults with tetralogy of Fallot and pulmonary atresia who developed lung abscesses, including some infected with atypical microbial pathogens, with important morbidity. We hypothesize that patients with such anatomy are at risk for chronic pulmonary infection due to hypo-perfusion of the pulmonary parenchyma. This previously unreported clinical association should be considered in the differential diagnosis of patients with tetralogy of Fallot and pulmonary atresia who alter their respiratory state.
