A natural systemic to pulmonary artery shunt

We report a case in which this subclavian artery was supplying the pulmonary circulation in a patient with tetralogy of Fallot (TOF) which effectively acted as a natural systemic to pulmonary artery shunt. The patient had good room air saturation and no features of vertebrobasilar insufficiency or left upper limb ischemia. She underwent a total correction of TOF and ligation of the aberrant left subclavian artery.
