Video 21.21 Type B interruption in a neonate scanned shortly after delivery
Type B interruption in a neonate scanned shortly after delivery. The short interruption between the left carotid artery and the descendent thoracic aorta distal to the arterial duct is demonstrated on this 2D color Doppler echocardiogram. Note the left subclavian artery is not visualized because its origin is more posterior to the scan plane.
