Mitral valve regurgitation is the most common type of heart valve disease. In this condition, the valve between the left heart chambers doesn't close fully. Blood leaks backward across the valve. If the leakage is severe, not enough blood moves through the heart or to the rest of the body.
30 kwi 2024 · Mitral regurgitation is a heart condition characterized by the incomplete closure of the mitral valve, leading to the backflow of blood from the left ventricle into the left atrium during systole. This results in a systolic murmur heard at the apex of the heart, often radiating to the left axilla.
If you have mitral valve regurgitation, a whooshing sound called a murmur may be heard. The mitral valve heart murmur is the sound of blood leaking backward through the valve. Tests may be done to confirm a diagnosis of mitral valve regurgitation or to check for other conditions that can cause similar symptoms.
24 maj 2024 · Mitral regurgitation is a heart valve problem that causes blood to flow backward into the left atrium. Learn how it affects the heart, lungs and veins, and what treatments are available from the American Heart Association.
In mitral valve regurgitation, the flaps don't close tightly. Blood flows backward when the valve is closed, making it harder for the heart to work properly. In mitral valve stenosis, the valve opening narrows. The heart now must work harder to force blood through the smaller valve opening.
Mitral valve (MV) regurgitation is the most common valvular heart disease in the United States and the second most common in Europe, with a prevalence of about 1.7%, which increases up to 9.3% in those ≥75 years of age.1,2 In the United States, mitral regurgitation (MR) incidence was >2 million adults in 2000 and is expected to double by 2030.3
Mitral regurgitation (MR) is the second-most frequent valvular heart disease in Europe. MR can be classified as primary (or organic) or as secondary (or functional). Primary MR is characterised by a primary lesion involving one or more components of the mitral valve (MV) apparatus.
