What is mitral regurgitation?

The causes of mitral regurgitation include leaflet injury, valve annulus enlargement, chordae tendineae rupture, etc. The specific analysis is as follows:

1. Leaflet injury

will affect the normal physiological structure of mitral valve, resulting in abnormal mitral valve function, affecting the direction of blood flow, resulting in mitral regurgitation phenomenon.

2. Valve annulus enlargement and valve

annulus enlargement will cause mitral valve insufficiency. During cardiac contraction, blood will flow back to the left atrium, affecting cardiac hemodynamics, resulting in the above conditions.

3. chordae tendineae

rupture may also lead to mitral valve insufficiency, thus affecting heart valve function, resulting in change of blood flow direction, resulting in mitral regurgitation.
