The mitral valve is located on the left side of the heart between the left atrium and left ventricle. The purpose of the mitral valve is to form a seal between these two chambers of the heart to prevent the back flow of blood. When blood enters the left side of the heart, it is oxygenated and enters through the pulmonary veins. The blood then travels through the left atrium; the bicuspid (mitral) valve then opens to let the blood flow down to the left ventricle. The left ventricle contracts, causing the mitral valve to close (preventing the backflow of blood).When the left ventricle contracts it is pumping the blood out to the remainder of the body. (Jenkins, 2007)
The mitral valve is made up of two thin leaf like structures that resembles the look of a parachute. The valve is attached to the wall of the left ventricle by a stringy structure called chordae tendineae. When a patient is affected by mitral valve prolapse, the structure of the valve and the chordae tendineae are affected by myxomatous degeneration. An abnormal thickening of the valve flaps is caused by a build-up of small collagen tumors. (American Heart Association, 2013) The prolapse is caused by the inability for the chordae tendineae to pull the valve tight during the late stages of systole. As the left ventricle decreases in size the chordae fails to maintain tension on the mitral valve, therefore causing regurgitation into the left atrium. (Systolic Murmurs- Mitral Valve Prolapse)
When the valve does not close properly it can cause mitral regurgitation. Mitral regurgitation is the leaking of blood from the left ventricle back into the left atrium. Mitral regurgitation can cause the heart to enlarge and over work to compensate for the blood that has traveled back into the atrium. (National Heart, Lung, and Blood Institute, 2011) This in return can lead to the development of heart failure. Regurgitation can also cause an

    Heart valve replacements are more common than most people think. In the United States it is said that over 99,000 heart valve surgeries are performed yearly. The majority of the valve replacement surgeries are to replace or repair the mitral or aortic valve, since the left side of the heart works harder than the right. There are several types of valve disease, the two most common are valvular stenosis and valvular insufficiency. Valvular stenosis occurs when the opening of the valve is smaller…

    most common is a mitral heart prolapse. More of a defect than a disease, but equally as troublesome, mitral heart prolapse afflicts as many as 8 million people in the United States alone. Essentially it is a faulty heart valve, particularly the mitral valve (hence the name). Because of this valve’s malfunction, when the heart normally contracts to pump blood through the body, the mitral valve slips back into place too fragile. In direct opposition to this condition is mitral valve stenosis that is…

    MITRAL VALVE DISEASE MITRAL STENOSIS Mitral stenosis is almost always rheumatic in origin, although in the elderly it can be caused by heavy calcification of the mitral valve apparatus. There is also a rare form of congenital mitral stenosis. In rheumatic mitral stenosis, the mitral valve orifice is slowly diminished by progressive fibrosis, calcification of the valve leaflets, and fusion of the cusps and subvalvular apparatus. The flow of blood from left atrium to left ventricle…

    Mitral Valve aka Bicuspid Valve Human Anatomy & Physiology II The left atrioventricular valve, with two cusps, is called the mitral valve because it resembles the two-sided bishops miter or hat. It is sometimes called the biscuspid valve. (Marieb & Hoehn, 2007). This valve separates the left atrium of the heart from the left ventricle of the heart. It prevents the back flow of oxygenated blood to the pulmonary circuit. Heart valves are simple devices, and the heart – like any…

The chordae tendinae, or heart strings, support the atrioventricular valve because the heart strings connects the papillary muscles to the tricuspid and mitral valve. 7.

    Uterine prolapse is one of an assemblage of conditions jointly referred to as pelvic organ prolapse in which loss of pelvic support leads to the protrusion of pelvic organs (uterus, bladder, or bowel) into the vagina. Uterine prolapse is a common issue for females and might befall alongside with bladder prolapse, bowel prolapse or both. Support of the pelvic organs is provided by an overlying system of ligaments, fascia and muscles. There might be many reasons for loss of this support. A blend of…
