Mitral stenosis – early stages
Balloon dilatation or (BMV).
Mitral valve lies between left atrium & left ventricle & its function is to open & close.
Oxygenated blood comes from lungs to left atrium, & then via two leaflets of mitral valve blood passes to left ventricle for distribution to body organs by contraction of left ventricle. When left ventricle contracts at that time Mitral valve closes & aortic valve opens to allow blood to go to body.
Normal mitral valve function is to regulate blood flow in right direction to body & not backwards to lungs. With each heart beat two leaflets of Mitral valve come together & close to prevent backward flow of blood. When heart relaxes leaflet of Mitral valve also relax & open the valve and blood comes to left ventricle. This cycle continues as normal heart function.
The disease
Mitral valve may get damaged by
-
Congenital
Congenital malformations / genetic disease.
-
Infections
Mostly rheumatic infection, bacterial endocarditis, fungal infections or others.
-
Degenerative
Degenerative valvular calcifications.
-
Muscle damage
Supporting muscle system damage following heart attacks.
-
Other causes
Tumors etc., IHSS / HOCM.
These diseases damage mitral valve & cause either narrowing (stenosis) or leakage (regurgitation).
Condition
Mitral stenosis
It is narrowing of mitral valve opening due to various causes which leads to accumulation of blood in left atrium & later on in lungs as back flow resulting in dilatation of left atrium then right ventricle which results into right sided heart failure.
Mitral incompetence / regurgitation
Mitral valve does not close adequately due to disease, blood regurgitates from left ventricle to left atrium every time when left ventricle contracts. This ultimately leads to heart failure.
Treatment options
Stage-wise treatment pathway
Later stage
When valve is still not significantly damaged then – CMV or open mitral valvotomy.
Last stage
1) Mitral valve repair
2) Mitral valve replacement
Mitral regurgitation
Non surgical: Mitra clip device.
Open heart surgery: 1) Mitral valve repair 2) Mitral valve replacement.
Mitral valve surgery
Choosing the right operation
Mitral valve surgery is usually considered with all investigations like Echo / cardiac MRI show the stages of mitral valve damage. Surgeon takes appropriate option of surgery depending on these findings. Mitral valve surgery may be performed as minimally invasive procedure / key hole, robot assisted surgery or full open heart surgery depending upon extent of disease, comorbidities, risk factors, feasibility & long term successful results.
