Video 31.8 Right aortic arch, mirror image branching, and a left-sided ductus arteriosus from the innominate artery
Right aortic arch, mirror image branching, and a left-sided ductus arteriosus from the innominate artery. Echocardiogram in a transverse orientation from a suprasternal notch window demonstrating the transverse aortic arch coursing to the right of the echo-bright trachea and the left innominate artery bifurcating into the left common carotid and left subclavian arteries. The ductus arteriosus can be faintly seen coursing from the base of the left innominate artery to the proximal left pulmonary artery.
