DISCUSSION There are two types ofright-sided aortic arch, type I and type II, each resulting
from abnormalities in the complex embryologic development of the aorta. At an early fetal …

Right aortic arch may occur as an isolated anomaly or in combination with congenital heart
disease, its course under these two circumstances being generally quite different. With …

A little over 100 cases of right-sided aorta have been reported in the literature, but only
about 20 or 25 of these have been diagnosed during life. To this short list we wish to add …

1. Right aortic arch can be divided into 3 sub-groups according to the branching of the arch
vessels. 2. Right aortic arch and an aberrant left subclavian artery is the most common type …

Right aortic arch is a rare anomaly, the diagnosis of which is seldom established during life.
Paradoxically, it is the easiest of all the congenital anomalies of the circulatory system to …

Right aortic arch has long been known in the anatomical literature as a rare congenital
defect of the aorta. Maude Abbott (1) lists 13 instances of this abnormality in her collection of …

IN THIS paper we discuss the anatomic types of right aortic arch in terms of their relative
incidences, their significance, and how each can be recognized by simple roentgenographic …

THE aorta and its main branches develop from six pairs of branchial arches, which, during
the fourth week of pregnancy, conjoin the primitive ventral and dorsal aortas in the embryo. 1 …

The term “right aortic ar* ch” is used by Blackford et al.('32) for those cases in which the aorta
has arisen from a heart in normal position and arches over the right bi* onchus. Rprong and …

Discussion The aorta arises embryologically from six paired arches connecting the ventral
aorta and aortic sac with the right and left dorsal aortas. With caudal migration of the heart …
