The mitral valve is one of the four gates that are inside heart. Its function is to make the blood flowing in the same direction during the cardiac cycle.
The mitral valve is a complex structure that consists of different parts:
- Two veils, the anterior and posterior: Are the gates that open and close. They are implanted in a fibrous ring and its opening and closing movements are regulated by a chordal.
- A fibrous ring: It is a rigid structure that is part of the skeleton of the heart and works as a fulcrum of veils for movement. It is in continuity with the aortic and tricuspid valve separates the atrium and the left ventricle.
- Chordal: on one side they are inserted in the papillary muscles and the other on the edge of the veils. They are critical to maintaining the internal architecture of the heart and its ability to contract and to the closing of the valve is correct.
- Two papillary muscles: muscular projections are inside the left ventricle and are the supporting pillars of chordae.
- LV: left ventricle on all structures are built.
Mitral valve operation
The valve opening and closing is performed by a synchronous movement of all its components. Synchrony is that which minimizes wear structures as fragile as the mitral leaflets and allows them to withstand million cardiac cycles throughout life.
Therefore, when mitral valve repair, it is necessary to act on all components in order to restore the original balance.
