What causes heart valve insufficiency?

Heart valve insufficiency may be caused by congenital factors, infection factors, myocardial tissue degeneration and other reasons.

1. Congenital

factors in patients with congenital heart tissue development abnormalities, leading to local structural abnormalities, easy to cause heart valve insufficiency.

2. Infection factors

If the patient's myocardial tissue infection bacteria, viruses and other pathogens appear inflammatory reaction, due to inflammatory stimulation to damage the heart valve leaflets, resulting in heart valve insufficiency.

3.

Myocardial tissue degeneration in patients with myocardial tissue degeneration can cause calcification of the mitral annulus, aortic degeneration, etc., leading to atrioventricular conduction block-induced heart valve insufficiency.
