ABSTRACT

In the 60-70 years of last century began the systematic study of complex congenital heart disease. The group of Dr. de la Cruz at the National Heart Institute of Mexico, based the segmental analysis of these heart in experimental study of embryological development. We could include exceptions to the complex cadiopathies, adding to the segmental classification, atrial situs, ventricular loop pedicle of the great arteries, the infundibular analysis. This presentation describes for the first time as a separate entity in the segmental analysis cadiopathies with great arteries side by side as a group with a different developmental mechanism to transposition and normally related or crossed great arteries.
