Right Aortic Arch with Isolated Left Subclavian Artery in Association with Double Outlet Right Ventricle and Cor Triatriatum Sinister: Hitherto Unreported Association

Right-sided aortic arch with isolation of left subclavian artery (LSCA) is associated with a spectrum of congenital heart diseases, most commonly tetralogy of Fallot (TOF). However, to the best of our knowledge, its association with cor triatriatum has not been reported in literature so far. Moreover, present case highlights the rare concomitant presence of double outlet right ventricle (DORV) and cor triatriatum sinister with vertebral segmentation anomalies in association with isolation of LSCA.
