“…11,13,14,17,19,29,35 The risk is greater (over 90%) with the mirror-image branching type than with the right arch and aberrant left subclavian artery (10%). 1,36 A good-although not recentreview on the prevalence of right aortic arch in a large series of patients with CHD (3,500 patients) was published in 1966 by Hastreiter et al 21 A right aortic arch (usually the mirror-image branching pattern) has been reported in 13-34% of subjects with tetralogy of Fallot (Fig. 6), and the association with double-outlet right ventricle (20%) or truncus arteriosus (15-35%) was not rare.…”

“…It originates from the homolateral Pulmonary artery through a patent or closed ductus arteriosus. It is the least common type of RAA, occurring in 0.8% of a series of 298 RAA, reported by Stewart and associates [2] [3]. The embryological development of such a malformation can be explained by using the concept of "hypothetical double aortic arch plan" first given by Edwards in 1948 [4] [5].…”

Background: Isolation of Left Subclavian Artery (LSCA) is a rare subset of Right Aortic Arch (RAA). It is diagnosed as nonvisualization of LSCA in catheterization study. Case Presentation: Here we report an unusual case of Tetralogy of Fallot (TOF) with right aortic arch with isolation of left subclavian artery (LSCA). Here LSCA originated from left pulmonary artery (LPA) through an atretic patent ductus arteriosus (PDA). There was nonvisualization of LSCA in catheterization study and it was confirmed by Computed Tomography (CT) angiography. Re-implantation of LSCA was done to left common carotid artery (LCCA) so that the left upper arm maintains a better flow in the future. Conclusion: Isolation of LSCA especially with TOF is a very rare entity. Re-implantation of LSCA to LCCA was done in view of weak pulses in left upper limb. Results were satisfactory in the follow up period.

“…Stewart et al 1) classified the RAA into three types: (1) RAA with mirror-image branching of the major arteries (59.3%), (2) RAA with an aberrant left subclavian artery (39.5%), and (3) RAA with an contra-lateral side via the anterior communicating artery (AcomA). The left subclavian-and left external carotid artery were supplied from the right vertebral artery (VA) via reverse flow in the left VA.…”
