Minimal forward mitral-valve area was calculated from the hydraulic formulas of Gorlin and Gorlin. 9 The roentgenograms were evaluated by the roentgenologist, and mitral regurgitation was graded ...
Mitral valve stenosis, shown in the heart on the right, is a condition in which the heart's mitral valve is narrowed. The valve doesn't open properly, blocking blood flow coming into the left ventricle, the main pumping chamber of the heart.
Your mitral valve sits between your upper and lower left heart chambers. It opens and closes to ensure blood flows in the correct direction at the right time.
In abnormal conditions, blood may flow backward through the valve (mitral regurgitation) or the mitral valve may be narrowed (mitral stenosis). Rheumatic heart disease often affects the mitral valve; the valve may also prolapse with age and be affected by infective endocarditis.
When the left ventricle contracts, the mitral valve’s two leaflets close to prevent blood from flowing backward. The mitral valve also has a series of supporting fibers (chords) and muscles attached to the leaflets. These structures prevent the leaflets from bulging back into the atrium (prolapsing).
Mitral Valve Disease Mitral valve disease includes conditions that affect the mitral valve—one of the heart’s four valves responsible for regulating blood flow between the left atrium (which receives blood from the lungs) and left ventricle (which pumps blood to the body).

Mitral valve disease can slow blood flow to/from the heart, but together, we can evaluate your risks,causes and symptoms associated with mitral disease and review the treatment options available.
