Interrupted Aortic Arch

The aorta is the main blood vessel that carries oxygen-rich blood to the body. If a patient is diagnosed with interrupted aortic arch, the first part of the aorta does not connect to the aorta in the lower part of the body. A hole in the bottom chambers allows for oxygen-rich blood to reach the lower half of the body. This occurs by shunting blood across the hole – commonly referred to as the Ventricular Septal Defect (VSD) – and into the pulmonary artery. At this point, blood can go to the lungs via the brand pulmonary arteries or the patent ductus arteriosus (PDA) to the lower half of the body.
