Classfication
The most well-known classification was the fourfold system developed by Collett and Edwards in 1949.[1] Collett/Edwards Types I, II, and III are distinguished by the branching pattern of the pulmonary arteries:[2][3]
- Type I: truncus -> one pulmonary artery -> two lateral pulmonary arteries
- Type II: truncus -> two posterior/posterolateral pulmonary arteries
- Type III: truncus -> two lateral pulmonary arteries
The “Type IV” proposed in 1949 is no longer considered a form of PTA by most modern sources.[3]
Another well-known classification was defined by Van Praaghs in 1965.[4][3]
