Was ist eine mitralstenose?
Bei der Mitralklappenstenose kommt es zu einer Verengung der Mitralklappenöffungsfläche. Dadurch ist die Füllung der linken Herzkammer gestört. Als Ursache für die Stenosierung sind degenerative und entzündliche Veränderungen der Segelklappen mit ihren Chorda tendinae anzusehen.
Wie funktioniert die Mitralklappe?
Die Mitralklappe funktioniert wie ein Ventil zwischen linker Herzvorkammer und linker Herzkammer. Sauerstoffreiches Blut fließt aus den Lungen in die Vorkammer und durch die Mitralklappe in die linke Herzkammer. Von dort fließt das Blut weiter in den Körperkreislauf.
What is mitral stenosis and what are the symptoms?
Mitral stenosis is a narrowing of the mitral valve opening that blocks (obstructs) blood flow from the left atrium to the left ventricle. Mitral stenosis usually results from rheumatic fever, but infants can be born with the condition. Mitral stenosis does not cause symptoms unless it is severe.
What are the risk factors for mitral valve stenosis?
Risk factors for mitral valve stenosis include untreated strep infections and a history of rheumatic fever. Older adults are at increased risk of mitral valve stenosis. As you age, calcium deposits can build up around the mitral valve, which may lead to mitral valve stenosis.
What is the difference between mitral valve stenosis and RHD?
Mitral stenosis resulting from RHD is called rheumatic mitral stenosis. Although most mitral stenosis is caused by RHD, it can also result from a calcium build up on the heart valves. This is more common in older patients and is called calcific mitral stenosis. Is mitral valve stenosis treatable?
Can rheumatic fever cause mitral stenosis?
Rheumatic fever can damage the heart valves leading to rheumatic heart disease. Mitral stenosis resulting from RHD is called rheumatic mitral stenosis. Although most mitral stenosis is caused by RHD, it can also result from a calcium build up on the heart valves. This is more common in older patients and is called calcific mitral stenosis.
