Video 31.12 Right aortic arch with a left descending aorta and a left ductus arteriosus - Color Doppler box positioned more leftwards
Right aortic arch with a left descending aorta and a left ductus arteriosus. This is similar imaging sweep to that in Video 31.11 but with the color Doppler box positioned more leftwards. The proximal descending aorta is positioned to the left of the trachea and the ductus arteriosus arises from it and courses to the left of the trachea to drain into the main pulmonary artery.
