Effects of mitral stenosis : Chest pain , shortness of breath when lying flat , with exertion and attacks during the night or morning ( cardiac asthma ) , possibly coughing up blood ; any complaints from law failure , such as ankle edema .
===Effects of mitral valve stenosis:===
Hartkkloppingen by atrial fibrillation , which can cause embolism , such as a stroke . The valve can be opened by balloon angioplasty or surgically treated by valve replacement .
Chest pain, of breath when lying flat, with exertion and attacks during the night or morning (cardiac asthma), possibly coughing up blood; any complaints from right valve failure, such as ankle edema. Palpitations by atrial fibrillation, which can cause embolism, such as a stroke.

===Treatment===
The valve can be opened by balloon angioplasty or surgically treated by valve replacement.

*Billowing
Mitral valvular insufficiency (MI ) may result in decompensation on the left side . An MI results in back flow of blood from the left ventricle into the left atrium. This may eventually result in pulmonary hypertension and pulmonary edema. Pulmonary edema is manifested by shortness of breath , initially with exertion , but later at rest , orthopnea and nocturnal dyspnea attacks . On physical examination, pulmonary edema can be detected by fine crackles with particular dorsobasale lung fields .
*Prolapse
A complication that may be the left atrium increases , the electrical stimulation that is chaotic , with as a result of atrial fibrillation .
