Effects of mitral stenosis : Chest pain , | ===Effects of mitral valve stenosis:=== | ||
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. | |||
Click for mitral stenosis quantification . | ===Treatment=== | ||
The valve can be opened by balloon angioplasty or surgically treated by valve replacement. | |||

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 | ||
