Truncus Arteriosus

3D Model

Truncus arteriosus (1) is a congenital heart defect in which the two major arteries of the heart – the aorta (2) and the pulmonary artery (3) – fail to separate during development. Instead, they are joined to create one large vessel coming from the heart (1) instead of two separate arteries.
