Truncus arteriosus

Truncus arteriosus is a congenital heart defect. At birth, the heart has only one blood vessel and one valve, instead of the usual two arteries and two valves. It is always associated with a ventricular septal defect, which is a hole in the partition that separates the two ventricles.

The single output vessel from the heart means that oxygenated blood is mixed with unoxygenated blood and then enters the lungs and the rest of the body. The arteries that supply the whole body and the lungs originate from this single vessel. The subsequent increased volume of blood that enters the lungs may result in congestive heart failure and lung damage.
