সংজ্ঞা
Mitral valve prolapse (MVP) is a common, usually benign heart disorder. The mitral valve controls blood flow between the upper and lower chambers on the left side of the heart. Normally, blood should only flow from the upper chamber into the lower chamber. In MVP, the valve flaps don’t work properly. Part of the valve balloons into the atrium, which may be associated with blood flowing in the wrong direction or leaking back into the atrium.
কারণসমূহ
In most cases, the cause of MVP is unknown. In some cases, it appears to be an inherited genetic condition.
ঝুঁকির কারণ
Factors that may increase your chance of getting mitral valve prolapse include:
- Family history of mitral valve prolapse
- লিঙ্গ: মহিলা
- Age: 14 to 30
- স্কোলিওসিস
- Thin chest diameter
- Low body weight
- নিম্ন রক্তচাপ
- Chest wall deformities
- মারফান সিন্ড্রোম
- Grave’s disease
- Ehlers-Danlos syndrome
- Ebstein’s anomaly
লক্ষণ
People with mitral valve prolapse often do not have symptoms. If symptoms do occur, they may include one or more of the following:
- ক্লান্তি
- বুক ব্যাথা
- Panic attacks or anxiety
- অনিয়মিত হৃদস্পন্দন
- নিঃশ্বাসের দুর্বলতা
- হালকা মাথাব্যথা
রোগ নির্ণয়
Mitral valve prolapse can be heard through a stethoscope. A small blood leakage will sound like a murmur. When the mitral valve balloons backward, it may produce a clicking sound. Both murmurs and clicks are signs of MVP. An echocardiogram can confirm the diagnosis. You may also be asked to wear a Holter monitor for a day or two to record the electrical activity of your heart.
চিকিৎসা
In most cases, no treatment is necessary. Although no longer routinely recommended, you may need to take antibiotics prior to some দাঁতের and medical procedures. This is to prevent infections. Ask your doctor if you will need to take antibiotics.
If symptoms include chest pain, anxiety, or panic attacks, a beta-blocker medication can be prescribed. Ask your doctor whether you may continue to participate in your usual physical activities.
In very rare cases, the blood leakage may become severe. In these few cases, the mitral valve may need to be surgically repaired or replaced.
প্রতিরোধ
There are no guidelines for preventing MVP of unknown or genetic origin.
You may be able to prevent symptoms, through certain lifestyle changes:
- Limit your intake of caffeine.
- Avoid medications that speed up your heart rate, including decongestants.
- Exercise regularly, following your doctor’s recommendations.
