Paediatrics: Total anomalous pulmonary venous connection

All blood returning to the heart (systemic and pulmonary) returns to the right atrium, and an obligatory patent foramen ovale or ASD is necessary for survival.

Total anomalous pulmonary venous connection

 

All blood returning to the heart (systemic and pulmonary) returns to the right atrium, and an obligatory patent foramen ovale or ASD is necessary for survival. The pulmonary veins form a single channel and join the sys-temic venous circulation through either a supracardiac superior vena cava (SVC), intra- or infracardiac IVC connection.

 

Clinical features

 

Infants usually present in the first few days of life with varying degrees of obstruction, cyanosis, and congestive cardiac failure. Presentation will depend on the degree of obstruction to the pulmonary venous return.

 

Treatment

 

This is often a surgical emergency and anastomosis of the common pulmo-nary channel to the left atrium, with closure of ASD, and interruption of connections to the systemic venous circuit are required.
