Figure 1: (a) Two-dimensional and color flow echocardiographic image in parasternal short axis view showing perpendicular orientation of branch pulmonary arteries (left pulmonary artery is in long axis and right pulmonary artery is in short axis). (b) Two dimensional and color flow echocardiographic image in parasternal short axis view after probe manipulation showing the two branch pulmonary arteries in long axis. Please note that only the origin of right pulmonary artery from main pulmonary artery is clearly visualized and left pulmonary artery origin is not clear. (c) Two-dimensional and color flow echocardiographic image in suprasternal long axis view showing both pulmonary arteries imaged below arch of aorta (right pulmonary artery in short axis and left pulmonary artery in long axis). There is associated interrupted aortic arch with patent ductus arteriosus continuing as descending aorta. Color flow image assists in separating left pulmonary artery flow from patent ductus arteriosus
