What Are Common Vascular Rings and Slings?
Discussion
Vascular rings and slings are not that common a congenital heart problem (about 1% of all congenital heart defects), but do occur and arise from abnormal embryological development of the major vascular structures.
Embryologically the great vessels and their major branches arise from the aortic sac.
The aortic sac forms two horns – a right and a left. These horns then form aortic arches.
The aortic arches with their paired branches then course into the pharyngeal arches.
Initially these aortic/pharyngeal arches have symmetric vascular pairs, but as development progresses they become asymmetric (basically du...
