The branches are lopped away, leaving literally the 'truncus' as the part of the tree out of which log and rafter can be cut.
This condition is known as truncus arteriosus or persistent truncus arteriosus (the trunk "persists").
In almost all cases, children with truncus arteriosus also have a large hole between the bottom chambers of the heart.
If fetal development progresses normally, the truncus divides into two arteries that carry blood out of the heart: the pulmonary artery, which is attached to the right bottom chamber (ventricle) of the heart and divides into two arteries carrying oxygen-poor ( "blue") blood to each side of the lungs the aorta, which is attached to the left bottom chamber (ventricle) of the heart and carries oxygen-rich ( "red") blood to the body.
A number of children with truncus arteriosus also have a genetic syndrome called 22q11 deletion syndrome (also known as DiGeorge, velocardialfacial or conotruncal anomaly face syndromes).
A child who has had surgical repair of truncus arteriosus will require life-long care by a cardiologist.
