Interrupted aortic arch occurs when the first part of the aorta does not connect to the aorta in the lower part of the body.  The aorta comes from the left ventricle and stops between the left carotid and left subclavian arteries, casing the gap or interruption. The arch starts again and travels the normal path down to the lower body.

An interrupted arch often occurs in ventricular septal defects(VSD), a hole that is between the two ventricles.
