Figure 2: Distal branch pulmonary artery stenosis. Axial computedtomographic image of a patient with a degenerated bioprosthetic valve (a) implanted for pulmonary regurgitation after truncus repair with absent left pulmonary artery shows stenosis between the pulmonary trunk and the lone right pulmonary artery. A second patient (b) after initial left modified Blalock–Taussig shunt followed by conduit repair for tetralogy has stenosis of origin of left pulmonary artery near the shunt insertion. PA: Pulmonary artery, LPA: Left pulmonary artery, SVC: Superior vena cava, RPA: Right pulmonary artery
