Abstract
Systemic venous anomalies can occur in isolation or in association with other congenital heart disease. A left superior vena cava draining to a roofed coronary sinus represents the most common venous variant and is usually inconsequential. Embryologic or acquired disruptions in systemic veins can be problematic due to shunting and/or venous obstruction. In this case series, we report four systemic venous anomalies in patients with atrial and ventricular situs solitus. Each case demonstrates how clinically significant right to left shunts can occur from a systemic vein to the left atrium. Diagnosis in each of these patients was delayed due to suboptimal diagnostic testing. Accurate diagnosis can be made by thorough anatomic evaluation of the presence, patency, and drainage of all systemic veins and supported with proper planning and interpretation of bubble studies.
