A case of isolated right subclavian artery and right patent ductus arteriosus successfully treated with catheter intervention in early infancy

In isolated subclavian artery, abnormal aortic arch development causes a loss of continuity with the aorta. Patent ductus arteriosus is a known cause of congestive heart failure. Herein, we present a rare case of congestive heart failure caused by isolated right subclavian artery and right patent ductus arteriosus associated with left-sided aortic arch treated by early closure.
