Truncus Arteriosus is a rare congenital heart defect. Instead of a baby having two main arteries (the aorta and pulmonary artery) they have only one large one. Their oxygen levels will usually be slightly lower than normal, and congestive heart failure (CHF) usually develops within the first week of life. Some of the symptoms of CHF are shortness of breath, wheezing, rapid and/or noisy breathing and restlessness.
In frogs, the truncus arteriosus gives rise to three main divisions in each branch: the systemic arch, the pulmocutaneous artery, and the dorsal aorta. The systemic arch supplies blood to the body, the pulmocutaneous artery delivers blood to the lungs and skin, and the dorsal aorta carries oxygenated blood to the rest of the body.

Patent Ductus Arteriosus
In fetal circulation, the ductus arteriosus is a connective vessel between the pulmonary artery and aorta. It works as to bypass the lungs, which are collapsed in the womb. After birth, the ductus arteriosus normally closes.
Ductus arteriosus
The conus arteriosus is a single, wide arterial vessel leaving the ventricle and passing ventrally over the right atrium.
Patent ductus arteriosus, or PDA, is a type of heart murmur that radiates to the back. It occurs when an infant's ductus arteriosus does not close after birth.
The function of the ductus arteriosus in unborn animals is to sent through the pulmonary artery to the aorta via the ductus arteriosus.
