Key result
A fetus presented with right ventricular hypertrophy secondary to an S-shaped ductus arteriosus with distal constriction diagnosed by pulsed Doppler imaging.
Case Report (n=1)
Highlights a rare case of idiopathic constriction of the fetal ductus arteriosus diagnosed by pulsed Doppler imaging.
Prompts consideration of ductus arteriosus anomalies in fetal RV hypertrophy; single case leaves open prevalence and outcomes.
Constriction of the ductus arteriosus in the fetus is well studied, but mostly secondary to maternal exposure to indomethacin or other non-steroidal anti-inflammatory medications, or structural cardiac lesions. We present a case of a fetus presenting with right ventricular hypertrophy secondary to an S-shaped ductus arteriosus with distal constriction diagnosed by pulsed Doppler imaging. A review of the recent English literature of similar cases is presented.

Trevett et al. (2004) conducted a case report in Idiopathic constriction of the fetal ductus arteriosus (n=1). Idiopathic constriction of the fetal ductus arteriosus was evaluated on Right ventricular hypertrophy. A fetus presented with right ventricular hypertrophy secondary to an S-shaped ductus arteriosus with distal constriction diagnosed by pulsed Doppler imaging.
