Mitral valve diseases
The heart is a pump consisting of 4 chambers:2 atria and 2 ventricles and 4 valves one of them is mitral valve which is located betweenthe left atrium and the left ventricle and prevents the backward flow of blood.Ithas several unique features: Mitral annulus, two leaflets, the chordae tendineaeand papillary muscles. The mitral valve may become stenotic or may regurgitate. Regurgitation(or leakage of the valve): When the valve (s) do not close completely. Stenosis (or narrowing of the valve): When the valve (s) opening becomes narrowed. Mitral stenosis is categorized as mild, moderate or severe it is typically causedby (Rheumatic fever, A congenital heart, Calcium deposits .....) and it caused severalsymptoms such as: dyspnea, hemoptysis, fatigue, Chest pain and others Where as the Signs and symptoms of mitral valve regurgitation, can include: Abnormal heart sound, Shortness of breath, Heart palpitations, Fatigue, edma, Coughing.
Aortic valve disease
Your heart has four valves to keep blood flowing in the direction. These valves include the mitral valve, tricuspid valve, pulmonary valve and aortic valve. Each valve has flaps (epiphysis or leaflets) that opens and close once during each heartbeat sometimes the valve do not open or close completely; this interferes with the flow of blood inside the heart, and may lead to impaired ability to pump blood to your body. In aortic valve disease, the aortic valve between the lower left chamber (left ventricle) and the primary artery that delivers blood from the heart to the body (the aorta) does not work completely. It may not close completely; This causes blood to leak back into the left ventricle (regurgitation), or possibly narrowing of the valve (stenosis).
