Mitral valve prolapse is a very common heart valve abnormality. It is also known as “click murmur syndrome” and “Barlow’s syndrome”. Women are more susceptible to this condition than men. A normal mitral valve is composed of two thin leaflets that are located between the heart’s left atrium and left ventricle.
During mitral valve prolapse, as the heart muscles contract during each beat, the lids (leaflets) of the heart’s mitral valve bump (prolapse) like a parachute into the heart’s left upper chamber (left atrium).
Click-murmur syndrome is yet another term for mitral valve prolapses. When a physician uses a stethoscope to listen to your heart, they may hear a clicking sound as the valve leaflets droop back, preceded by a whooshing sound (murmur) as blood flows back into the atrium.
Mitral prolapses occur when the mitral valve tissues are abnormally large or damaged, causing the valve to slip backwards. The mitral valve prolapse causes are unknown in the majority of cases.
Prolapse of the mitral valve can run in families. Conditions that cause aberrant cartilage might also cause it.
Mitral valve prolapse is more prevalent in women between 20 and 40, but it can also affect men. Although the exact mitral valve prolapses cause is unknown, it has a strong hereditary tendency. Family members who are affected are typically tall, thin, and have long arms and fingers, as well as straight backs.
Mitral valve prolapse is a lifelong health condition that may be asymptomatic. However, when blood leaks backwards, you can experience mitral valve prolapse symptoms due to mitral valve regurgitation. The signs can be different and show up over a long time. They might be
Even though most people with mitral prolapses have no problems, complications can occur. Mitral valve regurgitation is one of them. The most common complication is when the valve leaks blood back into the left atrium. Mitral valve regurgitation is more likely if you’re a man or have high blood pressure. To avoid heart failure, you may need surgery to repair or replace the valve if regurgitation is severe.
Irregular heart rhythms are most common in the heart’s upper chambers. They can be inconvenient, but they are rarely life-threatening. Those with severe mitral valve regurgitation or deformity are at a greater risk of developing rhythm problems, which can impair blood flow through the heart.
The endocardium is a thin lining on the inner side of the heart chambers. An abnormal mitral valve increases the risk of bacterial infection in the inner lining of the heart, which further damages the mitral valve.
Before determining a diagnosis, your doctor will usually do several tests to understand more about your heart.
Most of the time, your doctor will first notice Mitral Valve Prolapse when they detect a heart murmur or other abnormal sound with a stethoscope.
Other tests used to diagnose Mitral Valve Prolapse include:
Most people have no mitral valve prolapse symptoms, so treatment is rarely required. But if you have noticeable symptoms, your doctor may decide to treat you.
Medications are often used as part of the treatment to help relieve symptoms. Some of the drugs your doctor might give you are:
Surgery is done for severe regurgitation or heart failure. If the valve is not repaired, it is replaced with a mechanical or biological valve manufactured from cow, pig, or human tissue. Before the treatment, your doctor will review the advantages and disadvantages of both valves.
Mitral regurgitation can cause heart failure, enlargement, and abnormal rhythms in patients with mitral valve prolapse. This is why patients with mitral valve prolapse and regurgitation are recommended to get frequently evaluated on an annual basis.
Most people who suffer from mitral valve prolapse have a good prognosis and do not require mitral valve prolapse treatment. Routine examinations, including echocardiograms every few years, are the best preventive measure for people dealing with mitral valve prolapse.
