Rare Fetal Case of Absent Ductus Venosus With Extrahepatic Drainage Into the Coronary Sinus

Abstract

Absent ductus venosus (ADV) is a rare anomaly that is often associated with significant fetal anomalies and chromosomal aneuploidies. Prognosis depends on the pattern of drainage of the umbilical vein and the associated anomalies. The ductus venosus carries oxygenated blood from the umbilical vein to the inferior vena cava and prevents fetal high output heart failure by providing a resistor against placental blood flow. This case demonstrates echocardiographic delineation of a rare variant of ADV, with extrahepatic drainage from the left superior vena cava into the coronary sinus.
