Narrowing the valve between the left upper and lower chambers of the heart is known as\u00a0<em>mitral stenosis<\/em>.

Degeneration of valve structures by age can lead to narrowing of the aortic valve causing aortic stenosis. As time goes by, these valves can get calcified, with deposit of compounds containing calcium. Then it is called\u00a0<em>calcific aortic stenosis<\/em>. Birth defect of the aortic valve in which it has only two cusps instead of the normal three is known as\u00a0<em>bicuspid aortic valve<\/em>. Bicuspid aortic valve can degenerate earlier than normal aortic valve causing aortic stenosis. Valves can also get narrowed due to deposition of other materials in certain diseases (<em>infiltrative disorders<\/em>).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What causes narrowing of heart valves?
