Abstract

An antenatal referral for fetal echocardiography at 20 weeks of gestation with the suspicion of a cyst in the right atrium led to the diagnosis of an aorta to right atrial communication in a fetus. It was considered to be right coronary to right atrial fistula by fetal echocardiography. There was no other fetal anomaly and the cardiac hemodynamics remained stable throughout pregnancy. Postnatally, there was a progressive enlargement of the tunnel that led to a decision for intervention. Aortography showed an anterior aorta to right atrial tunnel, which was occluded in the catheterization laboratory. We describe in this report, the antenatal findings noted in ultrasound imaging along with the postnatal presentation and management of this rare congenital anomaly.
