It is possible that the main title of the report Truncus Arteriosus is not the name you expected. Please check the synonyms listing to find the alternate name(s) and disorder subdivision(s) covered by this report.
Truncus arteriosus is a rare type of heart disease that is present at birth (congenital) in which there is a single main blood vessel, rather than the normal two, carrying blood away from the heart. Instead of having a separate pulmonary artery, to carry blood to the lungs, and aorta, to carry blood to the rest of the body, a baby with truncus arteriosus has just one blood vessel leaving the heart which then branches into other blood vessels. Blood from both ventricles of the heart is mixed, resulting in a situation in which some oxygen-rich blood travels needlessly back to the lungs and some oxygen-poor blood travels to the rest of the body. Babies with this condition may have a bluish tint (cyanosis) to their skin, lips, and fingernails. In most cases, truncus arteriosus occurs in conjunction with a missing upper portion of the wall between the ventricles of the heart (ventricular septal defect).
