Mitral Valve Replacement

Topics: Cardiology
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 than normal causing the valve to work harder to push blood often resulting in heart failure and other serious conditions. Valvular stenosis can occur in any of the four heart valves, called tricuspid stenosis, pulmonic stenosis, mitral stenosis, and aortic stenosis. Valvular insufficiency, also called regurgitation or “leaky valve”, occurs when the valve does not close all the way. As the leak gets worse over time the heart has to then work harder to make up for the valve that is leaking also causing less blood to flow to the rest of the body. Valvular stenosis can occur in any of the four heart valves, called tricuspid regurgitation, pulmonary regurgitation, mitral regurgitation, and aortic regurgitation.

Sometimes the causes of valve disease are unknown. Some can develop before birth or a person can develop the condition over one’s lifetime. Congenital valve disease often affects the aortic or pulmonic valve from the valve being the wrong size, having malformed cusps, or having cusps that are not attached properly to the annulus. Bicuspid aortic valve disease is a congenital valve disease that affects the aortic valve, instead of the three normal cusps of the tricuspid the bicuspid aortic valve only having two and not having the third cusp causes the valve to become stiff or leaky with this disease. Acquired valve disease is when the problems develop with valves that were once normal. This disease can involve changes in the structure from a variety of diseases or

    Mitral Valve Prolapse Human Anatomy and Physiology II Kristen Ammen 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…

    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…

    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 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.
