TRICUSPID ATRESIA Meaning and
Definition
-
Tricuspid Atresia is a congenital heart defect characterized by the absence or severe underdevelopment of the tricuspid valve, which separates the right atrium and right ventricle in the heart. The tricuspid valve is responsible for allowing blood flow from the right atrium to the right ventricle, and its absence or blockage disrupts the normal blood circulation in the heart.
In a healthy heart, blood flows from the body into the right atrium, passes through the tricuspid valve into the right ventricle, and then gets pumped into the lungs for oxygenation. However, in individuals with Tricuspid Atresia, the tricuspid valve does not form properly, causing blockage or complete closure. This leads to a series of malformations and abnormal connections within the heart, affecting the circulation of blood and oxygen delivery throughout the body.
Due to the absence or severe narrowing of the tricuspid valve, blood from the right atrium must find an alternative route to reach the lungs for oxygenation. This is achieved through the presence of abnormal connections known as "shunts" or "collateral vessels." The severity of Tricuspid Atresia can vary, depending on the exact anatomical abnormalities present in each case.
Tricuspid Atresia is typically diagnosed during infancy or early childhood, as affected individuals often present with cyanosis (bluish discoloration of the skin) due to decreased oxygen levels in the blood. Treatment options for Tricuspid Atresia depend on the specific anatomical abnormalities and may involve surgical procedures, such as the creation of shunts or the reconstruction of the heart's structures, to improve blood flow and oxygenation. Long-term management may require regular follow-up appointments and medication to ensure optimal

Etymology of TRICUSPID ATRESIA
The word "tricuspid" comes from the Latin "tri-" meaning three, and "cuspid" meaning point or cusp. It refers to the tricuspid valve, which is a heart valve in the right atrium that has three cusps.
The term "atresia" comes from the Greek word "a-" meaning without or not, and "tresis" meaning perforation or passage. In the medical context, "atresia" is used to describe the absence or closure of a normal opening or passage in the body.
Therefore, "tricuspid atresia" is a medical term that describes a congenital heart defect where the tricuspid valve is either malformed or completely absent, leading to a lack of blood flow between the right atrium and the right ventricle.
