Causes of Mitral and Tricuspid Regurgitation

The causes of mitral regurgitation usually include mitral valve prolapse, mitral valve insufficiency, cardiomyopathy, etc. The specific analysis is as follows:

1. Mitral valve

prolapse refers to the flaccidity or prolapse of the mitral valve leaflets, resulting in the failure of the leaflets to close normally, resulting in regurgitation.

2. Mitral valve insufficiency The

structural abnormality or damage of the mitral valve, causing it to fail to close completely, causing regurgitation.

3. Cardiomyopathy

If the patient has cardiomyopathy, it can lead to changes in cardiac structure and function, resulting in mitral regurgitation.

The causes of tricuspid regurgitation include pulmonary hypertension, atrial fibrillation, heart valve disease, etc., and the specific analysis is as follows:

1. Pulmonary hypertension

Pulmonary hypertension will increase the load on the right ventricle, resulting in changes in tricuspid valve structure and function, causing regurgitation.

2. Atrial fibrillation

Atrial fibrillation can cause atrial enlargement and contraction function weakening, affecting tricuspid valve closure, resulting in regurgitation.

3. Heart valve disease Heart valve

disease includes tricuspid stenosis, tricuspid valve prolapse and other valve structural abnormalities or damage, which can lead to tricuspid valve regurgitation.
