ANATOMY

Detailed explanation-1: -The chordae tendinae (CT) are strong, fibrous connections between the valve leaflets and the papillary muscles . These are attached to the leaflets on to the ventricular side and prevent the cusps from swinging back into the atrial cavity during systole.

Detailed explanation-2: -Mitral/bicuspid valve: The mitral/bicuspid valve is the AV found between the left atrium and the left ventricle. It has two cusps and allows blood to flow from the left atrium to the left ventricle while preventing any back flow.

Detailed explanation-3: -The papillary muscles attach to the lower portion of the interior wall of the ventricles. They connect to the chordae tendineae, which attach to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle. The contraction of the papillary muscles closes these valves.

Detailed explanation-4: -The chordae tendineae known as the heartstrings are tendon resembling fibrous cords of collective tissue that connects the papillary muscles to the tricuspid valve and the tricuspid valve in the heart.

Detailed explanation-5: -Because the annulus resides in the left atrio-ventricular groove, and the chordae tendinae are connected to the ventricle via the papillary muscles, mitral valve function is integrally related to the ventricle.
