An extremely rare cause of Eisenmenger syndrome

Abstract

Persistent Truncus Arteriosus (PTA) is an extremely rare defect accounting for under 1% of all congenital heart disease, and over 85% of patients succumb to heart failure in infancy. We report a case of van Praagh type A3 PTA, which represents its rarest variant and accounts for only 8–10% of all patients with PTA. The presence of ductal stenosis in such cases is further exceedingly rare.
