Mitral valve auscultation

 

This is the valve which controls flow of blood between the lleft atrium and left ventricle. It has two cusps and hence its name is also bicuspid.

The left atrium is separated from the left ventricle by the left atrioventricular opening which is guarded by the mitral valve. This valve is connected to two papillary muscles which are further attached to the chordae tendinae at their free margins just as in the right ventricle.

The papillary muscles are called the anterior and posterior papillary muscles.

The sound of the mitral valve is best heard at the mitral area. This is the same as the apex beat of the heart.
