The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
It is an anatomical area located at the base of the right atrium, and its boundaries are the coronary sinus orifice, tendon of Todaro, and the septal leaflet of the right atrioventricular valve (also known as the tricuspid valve). [2] It is anatomically significant because the atrioventricular node is located at the apex of the triangle. The ...

Tricuspid valve separates right chambers- atrium from ventricle. As its name suggest, it has 3 leaflets (anterior, posterior and septal), all attached at the annulus of the leaflet that notably lacks any fibrotic tissue. [37] Apart from the leaflets and annulus, it also consists of three papillary muscles and three sets of chordae tendineae. [38]
Tricuspid atresia is the complete absence of the tricuspid valve which can lead to an underdeveloped or absent right ventricle. Pulmonary atresia is the complete closure of the pulmonary valve. Ebstein's anomaly is the displacement of the septal leaflet of the tricuspid valve causing a larger atrium and a smaller ventricle than normal.
The mitral valve and the tricuspid valve are known as the atrioventricular valves because they lie between the atria and the ventricles. [1] In normal conditions, blood flows through an open mitral valve during diastole with contraction of the left atrium, and the mitral valve closes during systole with contraction of the left ventricle. The ...

It is located at the center of Koch's triangle—a triangle enclosed by the septal leaflet of the tricuspid valve, the coronary sinus, and the membranous part of the interatrial septum. [ 3 ] Blood supply
