Abstract
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.

Isolation of Left Subclavian Artery (LSCA) from the right sided aortic arch is a very rare congenital anomaly and the least common type of Right Aortic Arch (RAA)

Summary
Isolation of Left Subclavian Artery (LSCA) from the right sided aortic arch is a very rare congenital anomaly and the least common type of Right Aortic Arch (RAA). The LSCA originates from the Left Pulmonary Artery (LPA) rather than the Aortic arch through the ductus arteriosus whether closed or patent [1]. We discuss a case of Tetralogy of Fallot (TOF) having sub aortic ventricular septal defect (S/A VSD), right ventricular outflow tract obstruction (RVOT) and pulmonary stenosis with isolated LSCA, who underwent successful Intra Cardiac Repair (ICR) for TOF and re-implantation of LSCA to Left Common Carotid Artery (LCCA)
