Truncus Arteriosus

Truncus Arteriosus

is a rare form of congenital heart disease that presents at birth. In this condition, the embryological structure known as the truncus arteriosus fails to properly divide into the pulmonary trunk and aorta. This results in one arterial trunk arising from the heart and providing mixed blood to the coronary arteries, pulmonary arteries, and systemic circulation.

Treatment is with neonatal surgical repair, with the objective of restoring a normal pattern of blood flow.
