The tricuspid valve, also called the right atrioventricular valve, gets its name because it is generally considered to have three leaflets: the anterior, posterior and septal leaflets. Of these, the anterior, also called the infundibular or anterosuperior, leaflet is typically the largest.
The atrioventricular valves of the heart are important in preventing backflow. The mitral valve prevents backflow into the left atrium, and the tricuspid valve prevents backfl â¦ ow into the right atrium.
