This mitral regurgitation is a fairly common health problem. Symptoms include heart murmurs, shortness of breath when lying down, fatigue, light-headedness, cough and swollen feet. Basically, any time you notice any change in your body you should see a doctor.

Mitral regurg is more commonly known as mitral valve regurgitation. When a person is diagnosed with mitral valve regurgitation it means that the mitral valve does not close as tightly as it should.

The mitral valve is located between your heart's two left chambers, and allows blood to flow forward through your heart during a normal heartbeat. Mitral valve regurgitation is also called mitral insufficiency or mitral incompetence.

Sometimes people may have only a mild case of mitral regurg. Other times, it may be very severe, even requiring heart surgery or a valve replacement. Symptoms may include heart murmur, fatigue, frequent urination, swelling inthe feet and ankles, and shortness of breath. It is very important to see a doctor when these symptoms are present. There may be many different reasons why a person may have mitral regurg. It may be caused by mitral valve prolapse, damaged tissue cords, rheumatic fever, endocarditis, heart defects, and previous heart conditions such as heart attack.

Mitral regurg. is an abbreviated form of mitral regurgitation. The mitral valve or bicuspid valve is an AV valve between the left atrium and left ventricle of the heart. Mitral regurgitation can be acute or chronic in nature. Chronic mitral regurg. is much more common, etiologies are many and can include rheumatic fever as a child or calcification of the mitral valve as an adult.

When the mitral valve is incompetent, blood back flows into the left atrium causing the atrium to dilate and hypertrophy to accommodate the increased volume of blood. The left ventricle also dilates in an attempt to maintain normal cardiac output.

Keep in mind that there are varying degrees of mitral regurgitation, this can be quantitated on echocardiogram. Many people have some degree of the problem but are unaware of it because it has never produced clinical symptoms. Other people of course have more extensive disease that chiefly results in pulmonary congestion and pulmonary edema.

The mitral valve's function is to prevent backflow of blood from the left ventricle to the left atrium on ventricular contraction.  In mitral regurg the valve does not perform this function at 100% efficiency thus allowing some back flow to occur.

Mitral regurg is a short name for the term mitral valve regurgitation. In general regurgitation, also called insufficiency, is the term used for disorder for any of the valves in the heart that do not close properly, resulting in blood leaking back into the chamber of heart from which it came. Thus mitral valve regurgitation is a disorder of mitral valve of the heart.

The mitral valve regulates the blood flow between the left ventricle of the heart. The most common cause of mitral valve regurgitation is the mitral valve prolapse (MVP). While small leaks in mitral vale do not present serious health problems, more serious cases can lead to heart failure over a period.
