Total Anomalous Pulmonary Venous Drainage at Cardiac Level
In 6 patients with total anomalous pulmonary venous drainage at cardiac level, differentiation between pulmonary veins entering the right atrium and those entering the coronary sinus was possible after selective angiocardiography into the pulmonary artery.
The principal feature of the angiocardiogram of the coronary sinus variety is an egg-shaped opacification over the spine within the right atrial contour. In the direct connection of pulmonary veins to the right atrium, the latter chamber may fill promptly after pulmonary venous return, sometimes starting as a circular shadow with the right atrium but never having the ovoid appearance of the coronary sinus variety.
