All of the following statements regarding total anomalous pulmonary connection are true except ?
**Core Concept**
Total anomalous pulmonary venous connection (TAPVC) is a rare congenital heart defect where the pulmonary veins do not connect normally to the left atrium. Instead, they connect to the right atrium or one of its tributaries. This condition can lead to pulmonary congestion and cyanosis due to the abnormal flow of oxygenated blood.
**Why the Correct Answer is Right**
In TAPVC, the pulmonary veins connect to the right atrium through a common chamber or separately to the superior vena cava, inferior vena cava, or coronary sinus. This abnormal connection leads to a decrease in oxygen saturation in the systemic circulation, resulting in cyanosis and potential cardiac failure. The connection can be supracardiac, cardiac, infracardiac, or mixed, depending on the location of the anomalous veins.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that TAPVC can present with a wide range of symptoms, from asymptomatic to severe cyanosis and cardiac failure. The diagnosis is often made through echocardiography, and surgical correction is necessary to restore normal pulmonary venous connection.
