TRUNCUS ARTERIOSUS Meaning and
Definition
-
Truncus arteriosus is a congenital heart defect characterized by the abnormal development of the major blood vessels leaving the heart during embryonic development. It is a rare condition where the pulmonary artery and the aorta, which are usually separate in a healthy heart, arise from a single vessel, known as the truncus arteriosus.
In a normal heart, the left ventricle pumps freshly oxygenated blood into the aorta, which supplies oxygen to the body's tissues. Simultaneously, the right ventricle pumps deoxygenated blood into the pulmonary artery, which carries it to the lungs for oxygenation.
However, in the case of truncus arteriosus, there is only one main blood vessel emerging from both ventricles, resulting in mixed blood flow. This defect causes oxygen-rich and oxygen-poor blood to mix together, leading to reduced oxygen supply to the body's tissues. Additionally, the excessive blood flow to the lungs can cause increased pressure in the lungs, leading to further complications.
Truncus arteriosus is typically diagnosed in infants shortly after birth or during prenatal ultrasound examinations. Surgical intervention is necessary to correct the problem and improve blood flow. The surgery involves separating the pulmonary artery and the aorta from the truncus arteriosus and creating a connection between the right ventricle and the pulmonary artery. This procedure allows for separate circulation of oxygen-rich and oxygen-poor blood.
Regular follow-up care is crucial for individuals with truncus arteriosus to monitor their heart health and manage any potential complications. With proper medical care and surgical intervention, many people with this condition can lead relatively normal lives.

Etymology of TRUNCUS ARTERIOSUS
The term "truncus arteriosus" is derived from two Latin words: "truncus", meaning "trunk" or "stem", and "arteriosus", meaning "arterial". "Truncus" refers to the fact that this condition involves a single arterial trunk arising from the heart, instead of the usual two separate arteries (the aorta and pulmonary artery). "Arteriosus" indicates that it is related to the arteries.
