Atypical Heart Defect in One of the Twins with Trisomy 21

Abstract

Twin gestations are higher risk pregnancies for fetal mortality especially when associated with genetic disorder and congenital heart defect which significantly increases the complication risk in the co-twin including fetal loss, premature delivery, and organ damage. In this report, we present a case of dichorionic twins in 41 years old woman. A trisomy 21 was diagnosed in one twin associated with uncharacteristic congenital heart defect resulting in single twin demise in mid-gestation . The effect of regular care and proper management was delivery of healthy surviving twin.
