Fig. 4From: Evaluation of the bronchial arteries: normal findings, hypertrophy and embolization in patients with hemoptysisCongenital causes of BAH—Tetralogy of Fallot and pulmonary agenesis. Significant bronchial artery hypertrophy (white arrows) in a patient with tetralogy of Fallot (a–c) and in a patient with pulmonary artery agenesis (d)—“image b” shows a ventricular septal defect, overriding aorta and right ventricular hypertrophy, features of tetralogy of Fallot. The black arrow in “image d” depicts the absence of the pulmonary artery. RV, right ventricle; LV, left ventricle; AA, ascending aortaBack to article page
