Mitral valve regurgitation
This is turn balances out the cardiac system. Can mitral valve regurgitation heal on its own? No, It is a structural abnormality of the heart. The symptoms of this may be more or less severe, at times, but the defect doesn't heal on it's own. Below is an image, showing the structure a normal valve and the one with a prolapse or regurgitating valve.
Remember from last month’s blog that disease in multiple valves is assumed to be rheumatic. Those codes can be found in I08.
This month, we’ll look at coding for mitral valve disease. The mitral valve is located in the left side of the heart between the atrium and ventricle. This valve is generally considered the second most important valve, secondary to the aortic valve. When the left atrium contracts, the mitral valve opens allowing the contents to be pushed into the left ventricle. Contraction of the left ventricle causes the mitral valve to close, preventing backward flow of blood into the left atrium. A normal healthy mitral valve has two leaflets that when closed, meet together closing the opening between the two heart chambers.
Mitral valve prolapse can sometimes lead to blood leaking back through the valve leaflets into the left atrium. This condition is now called mitral valve insu fficiency or regurgitation. Additionally, mitral insufficiency can occur without prolapse. Stenosis of the mitral valve is a narrowing of the valve opening, which restricts blood flow through the valve. Prolapse, insufficiency and stenosis can occur separately or in combination with each other.
