Tricuspid valve

Tricuspid valve

The tricuspid valve (lat. valva tricuspidalis) is one of the valves of the human heart, located between the right atrium and the right ventricle. The name is due to the fact that the valve consists of three leaflets (Latin cuspis), which open during diastole (relaxation of the heart), allowing blood to pass from the atrium into the ventricle, and close during systole (contraction of the heart), preventing the reverse flow of blood.

The leaflets of the tricuspid valve are attached by chordae, tendon strands, to the muscular protrusions in the cavity of the right ventricle. The leaflets are divided into anterior, posterior and septal (facing the interventricular septum). The anterior leaflet is the most mobile and most often damaged during pathological processes.

The tricuspid valve performs an important function - it regulates blood flow from the right atrium to the right ventricle, ensuring that blood flows in one direction. Damage to the valve leaflets or chords can lead to valve insufficiency and regurgitation (backflow) of blood, which impairs the functioning of the entire heart.



The tricuspid valve is one of the main components of the cardiovascular system and is a valve located between the right atrium and the right ventricle of the heart. It consists of three valves, each of which opens with the help of tendon threads. The valves close the opening, preventing blood from flowing back from the ventricle into the atrium.

The tricuspid valve is located at the bottom of the right side of the heart and projects into the right atrium from it. Tendon threads are attached to the top of the valve, which serve as its fixator. These threads connect to tendons attached to cartilage
