What is this disease?
Partial anomalous pulmonary venous connection (aka. partial anomalous pulmonary venous return) is a congenital heart defect. In this case, some of the pulmonary veins carrying blood from the lungs to the heart flow into other blood vessels or into the heart's upper right chamber rather than correctly entering the heart's upper left chamber, resulting in some oxygen-rich blood from the lungs mixing with oxygen-poor blood before entering the right chamber.
How about the diagnosis and treatment part?
To diagnose this condition, your doctor may review your signs and symptoms, conduct a physical exam, and listen to your heart with a stethoscope to check for a heart murmur. A specific test may be done with an echocardiogram. The doctor may also order other imaging tests, such as an MRI or CT scan.

There are multiple treatment options. They may include surgical repair with ASD patching, intracardiac baffle, anomalous vein anastomosis, systemic vein translocation and Warden procedure inter alia.
Can this disease be further divided into sub-branches?
Yes, there are four types of partial anomalous pulmonary venous connection (PAPVR). They are: supra-cardiac, cardiac, infracardiac and mixed PAPVR.
