Heart health is vital to overall health, and learning about mitral valve regurgitation symptoms can help people become aware of the early signs of a potentially major health issue. Mitral valve regurgitation is a medical condition where the mitral valve, which is located in the heart, is not functioning correctly, allowing blood to leak backward instead of flowing forward. This means that the heart has to work harder to pump blood throughout the body. This can, over time, lead to fatigue, respiratory issues, and other major complications related to heart health. Learning about the symptoms, causes, and treatments can help people receive medical care and maintain heart health.
Understanding Mitral Valve Regurgitation
The human heart is composed of four valves that control the flow of blood through the heart and ensure that the blood is pumped in only one direction. The mitral valve is the fourth valve located between the left atrium and the left ventricle. The main purpose of the mitral valve is to ensure that the oxygenated blood is pumped forward during each heartbeat from the left atrium into the left ventricle and then to the rest of the body.
The mitral valve disease occurs when the mitral valve fails to close properly, causing the blood to leak backward into the left atrium instead of pumping forward into the left ventricle. This prevents the normal functioning of the circulation of blood through the heart, causing the heart to work harder than normal.
The mitral valve disease can occur at various levels, ranging from mild to severe. The mild mitral valve disease will not show any symptoms for many years, while the severe mitral valve disease will have a significant influence on the functioning of the heart, leading to heart failure or abnormal heart rhythm.
How Mitral Valve Regurgitation Affects the Body?
When this blood flows back into the left ventricle, the heart has to work harder to pump the blood to the body. This will eventually cause the left ventricle to enlarge. This condition will eventually cause pressure to build up in the lungs, leading to breathing problems.
The condition may occur gradually over a long period or suddenly as a result of an injury, infection, or a heart attack. Since the condition develops gradually over time, people are not aware that they are suffering from the condition until the symptoms interfere with their daily activities.
Mitral Valve Regurgitation Symptoms and Signs
Early identification of the signs and symptoms of mitral valve regurgitation is important to prevent complications. The signs and symptoms differ depending on how severe they are and how quickly they occur.
The signs and symptoms include:
- Difficulty breathing, especially when exercising or lying down
- Fatigue, which makes it difficult to exercise
- Rapid and irregular heartbeats
- Heart palpitations, which is a sensation of fluttering in the chest
- Swelling of the legs, ankles, and feet
- Pressure or discomfort in the chest
- Dizziness
- A persistent cough, especially at night
Doctors can identify signs and symptoms through physical examinations, which include hearing a murmur. A murmur is a swishing sound made by blood flowing backward through the valve.
Mild Mitral Valve Regurgitation Symptoms
There are instances where people with mild symptoms of mitral valve regurgitation may not have any serious health issues. In some instances, the condition may remain steady for a number of years, and the patient may only be diagnosed with the condition during a routine check-up.
Some of the common symptoms of severe mitral valve regurgitation include:
- Fatigue after engaging in some level of physical activity
- Shortness of breath
- Heart palpitations
- Low level of endurance during exercises
Due to the low level of severity, some people may think that the symptoms are a normal part of the aging process or that the person is just stressed.
Severe Mitral Valve Regurgitation Symptoms
When the condition deteriorates, severe mitral valve regurgitation symptoms will manifest and significantly affect the quality of life. The severe leakage will put a strain on the heart and the lungs, resulting in more pronounced health issues.
Some of the severe mitral valve regurgitation symptoms include:
- Severe shortness of breath, even at rest
- Severe fatigue and weakness
- Swelling of the legs, feet, and abdomen
- Rapid breathing or difficulty breathing at night
- Arrhythmias, including atrial fibrillation
- Chest pain or discomfort
- Passing out or feeling dizzy
In severe mitral valve regurgitation, the condition will eventually lead to heart failure, pulmonary hypertension, or a stroke.
Causes of Mitral Valve Regurgitation
There are several medical conditions or structural issues that can cause mitral valve regurgitation. The most common causes of mitral valve leakage are:
Mitral Valve Prolapse: In this condition, the mitral valve leaflets will bulge backward into the left atrium instead of closing properly. This is one of the most common causes of mitral valve leakage.
Rheumatic Heart Disease: Rheumatic fever is caused by strep throat infections that are left untreated. This condition can damage the mitral valve, leading to leakage.
Heart Attack: During a heart attack, the muscles that support the mitral valve can be damaged, resulting in leakage.
Cardiomyopathy: In this condition, the heart muscle is enlarged or weakened, thus preventing the valve from closing properly.
Infective Endocarditis: In this condition, the infection in the valve will cause damage to the structure of the valve.
Congenital Heart Defects: Some people may have congenital heart defects that make the valves between the heart chambers leak.
Risk Factors: There are various risk factors that make someone prone to mitral valve leakage. The risk factors include:
- Age over 60 years
- Family history of heart valve problems
- High blood pressure
- Diabetes
- Smoking
- Obesity
- Previous heart attack
- Previous rheumatic fever
People with the mentioned risk factors should be cautious about symptoms of heart problems and visit their doctors regularly.
Complications of Untreated Mitral Valve Regurgitation
If left untreated, severe mitral valve regurgitation may result in serious health complications, such as:
- Heart Failure: The heart may become too weak to pump blood, resulting in heart failure.
- Atrial Fibrillation: Irregular heart rhythms may result from the enlargement of the left atrium.
- Pulmonary Hypertension: Increased pressure in the lungs may result from blood backing up into the pulmonary circulation.
Stroke - Stroke: Irregular heart rhythms may cause blood clots, which may travel to the brain and cause a stroke.
It is, therefore, essential to diagnose and treat the condition to prevent such complications.
Diagnosis of Mitral Valve Regurgitation
Several tests are conducted by doctors to diagnose this condition and assess the severity of the problem.
The common tests conducted for diagnosis of this medical condition are as follows:
- Physical Examination: It is possible for doctors to diagnose abnormal heart sounds with the help of a stethoscope.
- Echocardiogram: The echocardiogram is an ultrasound test, and the results show detailed images of the heart valves and blood flow.
- Electrocardiogram: The electrocardiogram is a test for abnormal heart rhythms, and the results show the heart’s activity and abnormal rhythms.
- Chest X Ray: The results of the chest X-ray show an enlarged heart or fluid accumulation in the lungs.
- Stress Testing: Exercise tests are conducted to assess how the heart responds to such exercises.
Treatment Options
The treatment depends upon the severity of the condition and the presence of symptoms.
Lifestyle Management
In mild cases, the condition may not need to be treated, but lifestyle changes are necessary.
The lifestyle changes that are recommended are:
- Heart-healthy diet
- Healthy body weight
- Physical activities
- Blood pressure control
- No smoking
Medications
Doctors may prescribe medications to help manage the symptoms and ease the workload of the heart. The medications that are prescribed are:
- Diuretics to help the body lose water
- Blood pressure medications
- Blood thinners to prevent the formation of blood clots
- Medications to control the heartbeat
Surgical Treatment
In severe cases, the damaged valve may need to be repaired or replaced.
The surgical treatments that are used are:
Mitral Valve Repair: In this procedure, the surgeon will repair the original valve to function properly.
Mitral Valve Replacement: In cases where the valve is not repairable, it is replaced with an artificial valve, either mechanical or biological.
