ANATOMY

Detailed explanation-1: -The mitral valve (/ˈmaɪtrəl/), also known as the bicuspid valve or left atrioventricular valve, is one of the four heart valves. It has two cusps or flaps and lies between the left atrium and the left ventricle of the heart. The heart valves are all one-way valves allowing blood flow in just one direction.

Detailed explanation-2: -The AV valves allow blood to flow from the atria to the ventricles, but not in the reverse direction. The right AV valve is called the tricuspid valve, the left is called the mitral valve.

Detailed explanation-3: -The mitral valve (MV) is an AV valve and connects the left atrium (LA) to the left ventricle (LV). The MV consists of an annulus (A, blue line), leaflets and chordae tendineae (CT) that insert into papillary muscles (PM) in the myocardial wall.

Detailed explanation-4: -The mitral valve gets its name from the resemblance to a bishop’s mitre (a type of hat). It is on the left side of the heart and allows the blood to flow from the left atrium into the left ventricle.

Detailed explanation-5: -The tricuspid valve opens and closes to ensure that blood flows in the correct direction. It’s also called the right atrioventricular valve.
