Truncus arteriosus is a rare congenital (present at birth) heart disease where a baby is born with a large hole between the two ventricles (ventricular septal defect) . The hole allows oxygenated blood to mix with blood that is low in oxygen. Some of this mixed blood goes to the lungs, and some goes to the rest of the body. Usually, more blood goes to the lungs. Over time, the blood vessels are permanently damaged and it becomes harder for the heart to pump blood to the lungs, resulting in pulmonary hypertension.
