What causes a small amount of regurgitation in the second and third mitral valves of the heart
VerifiedDedicated to your well-being.
The causes of small amount of mitral and tricuspid regurgitation include leaflet disease, valve annulus enlargement, chordal disease, etc.
1. Leaflet disease such
as rheumatic damage, infectious endocarditis, etc., can damage the structure and function of leaflets, resulting in mitral and tricuspid valve insufficiency, resulting in small amount of mitral and tricuspid regurgitation.
2. Valve annulus enlargement such
as chronic pulmonary heart disease, pulmonary stenosis, pulmonary hypertension, etc., can lead to left ventricular and right ventricular dilatation, and then cause mitral and tricuspid valve annulus enlargement, resulting in small amount of mitral and tricuspid regurgitation.
3. chordal disease such
as congenital abnormality, spontaneous rupture, secondary infection, etc., can also affect leaflet function, resulting in small amount of mitral and tricuspid regurgitation.
