The human heart comprises four chambers separated by valves. These tiny valves allow blood to flow in and out of the heart in a designated direction. One of them, the mitral valve, keeps blood moving from the left atrium to the left ventricle without a backflow. However, some blood leaks backward when this valve doesn’t close properly. This condition is referred to as Mitral Valve Regurgitation (MR).
Read on to know more about mitral valve regurgitation causes to stay informed.
Causes of mitral valve regurgitation
There are several potential causes of mitral valve regurgitation, and ongoing studies continue to explore them. Some possible causes include:
1. Mitral Valve Prolapse (MVP)
This is one of the most common causes of MR and often occurs with age. In this condition, the valve’s flaps (leaflets) become weak and don’t close properly, leading to leakage.
2. Heart attack (Myocardial infarction)
A heart attack puts immense pressure on the heart and can damage the muscles supporting the mitral valve, leading to improper valve closure. Heart attack is one of the leading causes of mitral valve regurgitation.
3. Rheumatic fever
This is a rare but serious complication of untreated strep throat. It can scar the mitral valve, making it stiff or weak, leading to leakage.
4. High blood pressure (Hypertension)
Long-term high blood pressure can enlarge the heart, affecting the function of all valves. It often puts extra strain on the valve, increasing the risk of regurgitation.
5. Ageing
As humans age, the heart valves may naturally wear out. Over time, the mitral valve may weaken or become stiff, leading to leakage.
6. Congenital heart defects
Some people are born with abnormalities in their mitral valve. These defects can cause regurgitation from an early age or develop later in life.
Conclusion
Knowing about mitral valve regurgitation causes can help with early detection and treatment. Regular heart check-ups can detect MR early, even before symptoms appear. Managing high blood pressure, infections, and heart health can lower the risk of this illness, but you must get yourself checked. Having health insurance will help cover the cost of surgeries related to mitral valve problems and hospitalisation.
