Truncus Arteriosus (Truncus)

Our heart starts as a single tube that undergoes a complex series of changes that result in the usual four chambered heart with one big artery serving the lungs and one big artery serving the body. If those changes don’t occur properly, there may be only one big artery which sends blood to both the lungs and the body. These babies will always have a ventricular septal defect as well.
