- It is an incredibly rare congenital heart defect
- 1 in 20,000 babies are born with it.
- The pulmonary veins do not drain into the LA but to the RA
- Survival requires an ASD or foramen ovale
- Supracardiac: where the pulmonary veins are connected to the Superior Vena Cava.
- Infracardiac is where the pulmonary veins join to the Inferior Vena Cava.
- Cardiac: where the pulmonary veins lead blood to the right atrium through the coronary sinus.
- Mixed: where the pulmonary veins are connected to various sites and so it is a mix between any or all of the previously mentioned forms of T.A.P.V.D
- Cyanosis and heart failure in the days after birth
- tachypnoea, murmurs, poor feeding
- CXR, ECG
- MRI of the heart
- Cardiac catheterisation
- Most of them require surgical repair in the newborn period.
