A new form of total anomalous pulmonary venous connection with double drainage

Totally anomalous "double drainage" of pulmonary venous confluence: case report with embryological aspects

Double drainage of the confluence of all four pulmonary veins is extremely rare. We present the image findings in a child with double drainage of the pulmonary venous confluence into the coronary sinus and left superior caval vein with co-existent right superior caval venous stenosis.

Dual Drainage of TAPVR—An Exquisite Connection

Dual drainage or double-connection total anomalous pulmonary venous return (TAPVR) is a rare variant in which all four pulmonary veins enter a common venous chamber that then drains into the systemic veins via two or more channels at the supracardiac, cardiac, or infra-cardiac levels. The traditional classification of total anomalous pulmonary venous connection (TAPVC) does not categorize dual drainage separately.

We present a case of TAPVR with dual drainage in a 6-year-old child with a rare variety of connection.

Double drainage of total anomalous pulmonary venous connection revealed after surgical repair of a supracardiac total anomalous pulmonary venous connection

Mixed type TAPVC with double drainage, where the second vertical vein enlarged rather than atrophied after surgery. If we did not recognize left-to-right shunting before surgery, it can be treated with catheterization as demonstrated by our case.

Double drainage of total anomalous pulmonary venous connection: A rare variant of mixed total anomalous pulmonary venous connection

Total Anomalous Pulmonary Venous Connection (TAPVC) is frequently classified based on the system proposed by Craig, Darling and Rothney. Occasionally variants are reported which do not fit into these classic forms. One such variant is the double drainage of TAPVC where the confluence has connections at two different levels. We report two infants with a double drainage pattern of TAPVC.

Asymptomatic Total Anomalous Pulmonary Venous Connection with Double Drainage in a Young Adult: A Case Report

Total anomalous pulmonary venous connection is an uncommon congenital anomaly in which all pulmonary venous return drains to the right atrium or one of its tributaries. Survival beyond infancy without surgical palliation is unlikely, so this anomaly is not encountered in the adult population with congenital heart disease. The patient presented here was 22 years old on admission and had no total anomalous pulmonary venous connection-associated symptoms. He underwent transthoracic echocardiographic examination for atypical chest pain. Transthoracic echocardiography along with cardiac catheterization favored the presence of a total anomalous pulmonary venous connection. Surgical correction of pulmonary venous confluence (draining to both the coronary sinus and right atrium) was performed successfully. This is a rare case of total anomalous pulmonary venous connection with no reported symptoms in contrast to the majority of patients who are symptomatic during the first year of life.
