Heart murmur???? what to do?

A heart murmur is caused by a faulty valve that allows blood to flow back into one of the chambers. I understand that. but why is this two-way flo so bad and why would it Create problems?

Mitral stenosis is a heart valve disorder that involves a narrowing or blockage of the opening of the mitral valve, which separates the upper and lower chambers on the left side of the heart.
In adults, mitral stenosis most commonly occurs in people who have had rheumatic fever. Since rheumatic fever rates are declining in the United States, the rate of mitral stenosis is also decreasing. Only rarely do other disorders cause mitral stenosis in adults.
Acute mitral regurgitation is a disorder in which the heart's mitral valve suddenly does not close properly, causing blood to flow backward (leak) into the upper heart chamber when the left lower heart chamber contracts.
Aortic stenosis is the narrowing or obstruction of the heart's aortic valve, which prevents it from opening properly and blocks the flow of blood from the left lower chamber of the heart to the aorta. The aorta is the main artery leaving the heart.
Aortic insufficiency is a heart valve disease in which the aortic valve weakens or balloons, preventing the valve from closing tightly. This leads to backward flow of blood from the aorta (the largest blood vessel) into the left ventricle (the left lower chamber of the heart).

Pneumatic Water Separator - Pneumatic Mist Remover From Nex Flow™

Newly developed "Liquid Super Separator" is a new concept of a pneumatic mist remover without filter element. The "Element Free Pneumatic Water Separator" uses a special centrifugal technique with "radial multi-nozzles" that is world patent pending and makes it possible to reject liquid mist (water and oil) to 99.9%! This pneumatic mist separator is virtually maintenance free, as there is no need to replace any filter element. A standard traditional filter with an element and automatic drain may be placed downstream to control micron size but the high liquid and mist removal of the separator will keep it clean and it may not require element replacement for an extended period of time. Maintains extremely low pressure drop.

Using The Super Separator

Very large water separators sometimes used upstream to remove liquid but it does not prevent downstream condensation due to the temperature difference between the inside and outside of the compressed air line.

The X-Stream™ Super Liquid Separator is installed at the end of a compressed air main line before a branch line, or just before the outlet of air use for the complete rejection of the mist due to the condensation inside the pipe and also remove any oil mist to 99.9%. This makes it possible to get an essentially maintenance free operation in the control of water and moisture in air line. The only possible part change would be the replacement of the auto drain valve giving the unit a semi permanent life time.

5-year warranty (except for auto drain)
