“…1,2 Approximately 60% of such patients have tetralogy of Fallot, double-outlet right ventricle, atrial and ventricular septal defects, or a combination of these. [3][4][5] Embryologically, the left 7th intersegmental artery migrates cephalad to the level of the ductal arch, after which the distal left dorsal aorta involutes, isolating the LSA from the aortic arch but maintaining its connectivity to the PA through the ductus arteriosus. 6,7 Thus, the LSA receives blood flow retrograde through the vertebral system, leading to a left-to-right shunt from the vertebrobasilar system to the PA. 8 After birth, a natural physiologic decrease in pulmonary vascular resistance occurs, and reversal of flow through the LSA results in subclavian steal, reversing blood flow from the brain and increasing blood flow into the lungs.…”

Isolated left subclavian artery is one of the rarer aortic arch anomalies. It has been associated with other congenital heart diseases, typically tetralogy of Fallot, double-outlet right ventricle, and atrial and ventricular septal defects. Its significant clinical implications include a left-to-right shunt from the vertebrobasilar system, which causes pulmonary overcirculation and subclavian steal. We present an unusual case of a premature infant who was diagnosed prenatally with congenital complete atrioventricular block and tricuspid atresia and was found to have an isolated left subclavian artery postnatally. The patient underwent implantation of a permanent single-chamber epicardial pacing system. To our knowledge, this combination of lesions has not been reported-and in our case, it influenced our surgical planning.

The angiocardiograms of 17 patients with aortic arch interruption are reviewed to emphasize the variations in arch interruption and origin of the brachiocephalic vessels, and collateral circulation to the descending aorta. Depending on the anatomical type and subtype of arch interruption, collateral flow to the descending aorta in the presence of a stenotic or closed ductus will be dependent on the development of intercostal collaterals and/or the presence of retrograde flow in all brachiocephalic vessels arising from the descending aorta. Familiarity with the potential pathways for collateral circulation may permit differentiation into types and subtypes on chest radiograph. Patients with Type I interruption may have bilateral rib notching if the right subclavian artery originates normally from the innominate artery, but will have rib notching confined to the left side if the origin of the right subclavian artery is aberrant. Type II or Type III interruption patients will have rib notching confined to the right side if the right subclavian has a normal origin, but no rib notching if the origin of the right subclavian artery is aberrant.
