Excerpt
Congenital discontinuous central branch pulmonary arteries, a conotruncal cardiac anomaly, can be an isolated finding [

4], whereas the right pulmonary artery normally is connected to the main pulmonary artery. The bilateral PDA or ductlike collateral vessels connect directly to the central branch pulmonary arteries, unlike major aortopulmonary collateral arteries, which connect indirectly. …
