Multimodality Imaging of Caval and Coronary Sinus Venous Anomalies.

• Abnormal fetal development can produce several anomalies of the caval venous system. • We present multimodality imaging of the most common caval venous anomalies. • Each imaging modality provides incremental value when identifying these anomalies. • Even normal variants may impact pacing lead or central venous catheter placement. • Pathologic variants may lead to intracardiac shunting.
