This infection causes swelling and muscle damage to the heart. It can also damage the heart valves in a way that keeps the blood from moving through the heart normally. The infection can cause heart valve leaflets to stick together, which narrows the valve opening. Also, the infection can scar the valves.
Heart attacks that damage the structures that support the mitral valve are a common cause of mitral valve insufficiency. Myxomatous degeneration can cause a "floppy" mitral valve that leaks.
Mitral valve
To correct damage to the mitral, aortic, pulmonary, or tricuspid heart valves caused by a systemic infection, endocarditis, rheumatic heart disease, a congenital heart defect, or mitral and/or aortic valve disease.
Having a mechanical mitral valve is considered a condition affecting the heart, but it is not a primary heart condition. Rather, it is a treatment for a different underlying heart condition, such as mitral valve disease or regurgitation. The mechanical valve is a prosthetic device used to replace a malfunctioning or damaged natural mitral valve.
Mitral Valve Insufficiency
Mitral regurgitation is backflow of blood through the mitral valve.
Generally healthy but are prone to mitral valve heart disease: a deterioration in one of the four sets of mitral valve's in a dog's heart. When it strikes, the mitral valve atrophes. The valve doesn't fully close after each pumping action, allowing blood to float backwards from the ventrical into the adrium. This can lead to valve collapse and ultimatley, heart failure.
The mitral valve is closed when the left ventricle is contracting.
left atrioventricular valve and left mitral valve
Mitral stenosis is the medical term meaning narrowing of the mitral valve.
The left atrioventricular valve is also known as the mitral valve.
