Technical considerations of coarctation stenting in double-barreled aorta – A persistent fifth arch mimic

Abstract

The double-barreled aorta connecting the ascending aorta and descending aorta caudal to the normal fourth aortic arch has fascinated the interests of cardiac morphologists for over a century. This condition is commonly associated with coarctation. While the controversies surrounding the embryology of the double-barreled aorta have settled down, we present a case-based illustration of the technical aspects of coarctation stenting peculiar to this condition.
