case_images: Cross-sectional echocardiogram (parasternal short axis view) showing (a) the LPA at its typical location (arrow) and absence of the RPA and (b) large left side PDA (asterisk). LPA: left pulmonary artery. RPA: right pulmonary artery.

case_images: A large PDA with bidirectional shunt was noted with a typical insertion to the LPA (Figure 1).
case_images: 3D reconstruction CT imaging from right posterior view shows the origin of the right pulmonary artery from the right subclavian artery (white arrows) and the left-sided PDA (asterisk). The stenosis of the RPA is also seen.

case_images: Since we could not see the right pulmonary artery on the echocardiogram, cardiac CT angiography was performed which demonstrated an isolated right pulmonary artery arising from the right subclavian artery (Figure 2).
case_images: Angiogram showing (a) a large size patent ductus arteriosus (asterisk), and (b) the right pulmonary artery originates from the right subclavian artery with a significant stenosis at the origin point (arrow).

case_images: The origin of the right pulmonary artery was demonstrated from the right subclavian artery with a significant proximal stenosis at the origin from the right subclavian artery (Figure 3).

case_images: Intraoperative images: (a) large size patent ductus arteriosus was obvious (arrow); (b) ligation of the PDA was performed.
