Mitral valve prolapse (MVP) is a condition that occurs when the valve between the left atrium and left ventricle of the heart doesn’t close properly. This can cause blood to leak backward into the left atrium, a condition known as mitral regurgitation. MVP is a relatively common condition, affecting about 2-3% of the population. It is often benign and may not cause any symptoms or complications. However, in some cases, MVP can lead to serious complications such as arrhythmias, heart failure, or infective endocarditis.
The exact cause of MVP is not fully understood, but it is believed to be a combination of genetic and environmental factors. It is more common in women and tends to run in families. In most cases, MVP is diagnosed during routine physical exams or tests for other heart conditions. Treatment is not always necessary, but in some cases, medication or surgery may be required to manage symptoms or prevent complications.
MVP is often referred to as a “click-murmur” syndrome because it is characterized by a clicking sound and a murmur heard through a stethoscope during a physical exam. The clicking sound occurs when the valve leaflets bulge back into the left atrium during systole, while the murmur is caused by the backflow of blood into the left atrium. Other symptoms of MVP may include palpitations, chest pain, fatigue, and shortness of breath. It’s important for individuals with MVP to be aware of their condition and seek medical attention if they experience any concerning symptoms.

Symptoms and Risk Factors
Symptoms of mitral valve prolapse can vary widely from person to person. Some individuals may not experience any symptoms at all, while others may have severe symptoms that significantly impact their quality of life. Common symptoms of MVP include palpitations, which are sensations of rapid, fluttering, or pounding heartbeats. These palpitations may be triggered by stress, caffeine, or physical exertion. Chest pain or discomfort is another common symptom of MVP, although it is usually not related to coronary artery disease. Fatigue and shortness of breath, especially during physical activity, are also common symptoms of MVP.
There are several risk factors that may increase the likelihood of developing MVP. As mentioned earlier, MVP tends to run in families, so having a family history of the condition is a significant risk factor. Additionally, MVP is more common in women than in men, particularly women who have given birth multiple times. Other risk factors for MVP include certain connective tissue disorders, such as Marfan syndrome or Ehlers-Danlos syndrome, and prior chest trauma. It’s important for individuals with these risk factors to be aware of the signs and symptoms of MVP and to seek medical attention if they experience any concerning symptoms.
Diagnosing Mitral Valve Prolapse
Diagnosing mitral valve prolapse typically involves a combination of a physical exam, imaging tests, and possibly an electrocardiogram (ECG) or echocardiogram. During a physical exam, a healthcare provider may listen for a clicking sound and a murmur using a stethoscope. They may also ask about any symptoms the individual is experiencing and their medical history. If MVP is suspected, the healthcare provider may order an echocardiogram, which uses sound waves to create a moving picture of the heart. This test can show the structure and function of the heart, including the mitral valve and any regurgitation that may be occurring.
An ECG may also be used to check for any irregularities in the heart’s electrical activity. This test involves placing electrodes on the skin to measure the electrical impulses given off by the heart. In some cases, additional imaging tests such as a cardiac MRI or CT scan may be used to get a more detailed look at the heart’s structure and function. Once a diagnosis of MVP has been confirmed, the healthcare provider will work with the individual to develop a treatment plan based on their specific symptoms and risk factors.
Treatment Options for Mitral Valve Prolapse
Treatment for mitral valve prolapse is not always necessary, especially if the individual is not experiencing any symptoms or complications. In cases where treatment is needed, it may involve medication or surgery. Beta-blockers or calcium channel blockers may be prescribed to help manage symptoms such as palpitations or chest pain. These medications can help regulate the heartbeat and reduce the workload on the heart. In some cases, blood thinners may be prescribed to reduce the risk of blood clots forming in the heart.
Surgery may be recommended for individuals with severe mitral regurgitation or other complications related to MVP. The most common type of surgery for MVP is mitral valve repair, which involves repairing the existing valve rather than replacing it with an artificial valve. This type of surgery is often preferred because it preserves the natural anatomy and function of the heart. In some cases, however, mitral valve replacement may be necessary if the valve is too damaged to be repaired. The type of surgery recommended will depend on the individual’s specific condition and overall health.
Lifestyle Changes for Managing Mitral Valve Prolapse
In addition to medication and possibly surgery, lifestyle changes can also play a role in managing mitral valve prolapse. Regular exercise can help improve overall cardiovascular health and reduce symptoms such as palpitations and fatigue. However, individuals with MVP should avoid high-intensity or competitive sports that could put excessive strain on the heart. Eating a healthy diet that is low in saturated fat and cholesterol can also help reduce the risk of developing other heart-related conditions such as coronary artery disease.
Managing stress is important for individuals with MVP, as stress can trigger palpitations and other symptoms. Techniques such as deep breathing, meditation, or yoga can help reduce stress and promote relaxation. It’s also important for individuals with MVP to avoid excessive caffeine and alcohol, as these substances can exacerbate symptoms such as palpitations and chest pain. By making these lifestyle changes, individuals with MVP can help reduce their risk of complications and improve their overall quality of life.
Surgical Interventions for Mitral Valve Prolapse
In cases where medication and lifestyle changes are not sufficient to manage mitral valve prolapse, surgical intervention may be necessary. As mentioned earlier, mitral valve repair is often the preferred surgical option for MVP because it preserves the natural anatomy and function of the heart. During this procedure, the surgeon will make repairs to the existing valve to improve its function and reduce regurgitation. This may involve tightening or reshaping the valve leaflets or repairing any ruptured chordae tendineae that are causing the valve to leak.
In some cases, mitral valve replacement may be necessary if the valve is too damaged to be repaired. This involves removing the existing valve and replacing it with an artificial valve made of metal or tissue. There are different types of artificial valves available, each with its own benefits and drawbacks. The type of surgery recommended will depend on the individual’s specific condition and overall health. After surgery, individuals will need to undergo regular follow-up appointments with their healthcare provider to monitor their progress and ensure that the new valve is functioning properly.
Prognosis and Long-Term Management
The prognosis for individuals with mitral valve prolapse is generally good, especially if the condition is mild and not causing any symptoms or complications. With proper management and regular follow-up care, most individuals with MVP can lead normal, healthy lives. However, it’s important for individuals with MVP to be aware of their condition and seek medical attention if they experience any concerning symptoms such as palpitations, chest pain, or shortness of breath.
Long-term management of mitral valve prolapse may involve regular check-ups with a cardiologist to monitor the function of the heart and the mitral valve. This may include periodic echocardiograms or other imaging tests to assess any changes in the structure or function of the heart. Individuals with MVP should also continue to take any prescribed medications as directed by their healthcare provider and make any necessary lifestyle changes to reduce their risk of complications.
In conclusion, mitral valve prolapse is a relatively common condition that occurs when the valve between the left atrium and left ventricle of the heart doesn’t close properly. While MVP may not always cause symptoms or complications, it’s important for individuals with this condition to be aware of their risk factors and seek medical attention if they experience any concerning symptoms. With proper diagnosis and management, most individuals with MVP can lead normal, healthy lives without significant limitations.
