The criteria for judging mitral valve regurgitation mainly depend on the percentage of the regurgitation area in relation to the left atrial area. If the area of mitral regurgitation exceeds 40% of the left atrial area, it is medically termed as severe regurgitation. If it is below 20%, it is considered mild regurgitation. Generally, patients with severe regurgitation require surgical treatment. This treatment can be conducted through mitral valve replacement surgery or mitral valve repair surgery. Surgical treatment can effectively prevent the occurrence of heart failure, thereby improving the quality of life and extending the patient's lifespan.

Is severe mitral valve regurgitation serious?

Mitral valve regurgitation can be mild, moderate, or severe, with severe mitral valve regurgitation being the most serious. Over time, severe mitral valve regurgitation can cause enlargement of the heart and a decreased heart pumping function, eventually leading to symptoms of heart failure. Patients may experience difficulty breathing, shortness of breath, fatigue, and other symptoms. Additionally, there may be swelling in both lower limbs. When such symptoms occur, it is necessary to take diuretic medications under the guidance of a doctor to reduce heart strain, such as furosemide or spironolactone. If necessary, digoxin may be taken to strengthen the heart and improve symptoms of heart failure. After stabilization, a mitral valve replacement or repair surgery may be scheduled.

Mitral stenosis increases the load on which ventricle?

If a patient exhibits symptoms of mitral stenosis, it primarily leads to an increased load on the left atrium and left ventricle, resulting in palpitations, chest tightness, and difficulty breathing. The current treatment mainly involves symptomatic therapy, using cardiotonic and diuretic medications to improve the patient's condition. Currently, medications are used in treatment to control symptoms like palpitations and chest tightness. It is advised that the patient should undergo a cardiac echocardiography to further confirm the diagnosis. In treatment, it is still necessary to control blood pressure, heart rate, and pulse changes. If there is a rapid heart rate or increased blood pressure, these should also be actively managed to reduce the cardiac load. Dietarily, it is recommended that patients adopt a light diet, particularly eating smaller, more frequent meals and avoiding spicy and irritating foods. It’s important to keep warm and avoid catching cold.

What to do with mild mitral and tricuspid regurgitation?

The appearance of mild regurgitation in the mitral and tricuspid valves requires further clarification of the specific causes leading to the regurgitation, and treatment should be based on these causes. In healthy individuals, mild regurgitation of the mitral and tricuspid valves may be considered physiological degeneration, which is not considered a disease and does not require special treatment. However, mild regurgitation of these valves can also occur due to related organic diseases causing ventricular enlargement and annular dilation, leading to relative mild regurgitation of the mitral and tricuspid valves. In such cases, effective treatment of the underlying disease is necessary to keep it stable in the long term, preventing further enlargement of the ventricle that could worsen valve regurgitation and adversely affect the patient.

Why does mitral stenosis cause enlargement of the left atrium?

Because mitral stenosis can lead to changes in the mitral valve, particularly causing excessive pressure in the left ventricle, this excessive pressure can lead to enlargement of the left atrium, which are complementary conditions. During this period, it is still important to actively manage the condition, using medication treatment. If the area of stenosis is relatively large, surgical treatment is needed, as balloon dilation can currently be used to alleviate this condition. Early treatment is best to relieve clinical symptoms. At the same time, it is also important to actively monitor changes in heart rate, blood pressure, and pulse, so as to control the heart rate and reduce myocardial oxygen consumption.

The cause of thromboembolism in mitral stenosis

The mitral valve is an important part of the left heart system, located between the left ventricle and the left atrium. When the heart is in diastole, the mitral valve opens, allowing blood from the atrium to be transferred into the ventricle. However, when the mitral valve is narrowed, blood from the left atrium cannot flow into the left ventricle in a timely manner. This leads to an increased load on the left atrium. Over time, this can cause severe enlargement of the left atrium and lead to atrial fibrillation, a type of cardiac arrhythmia. Once atrial fibrillation occurs, it can cause thrombosis in the left atrium, particularly in the part called the atrial appendage. If a thrombus forms, it may dislodge during the heart's contractions, potentially causing systemic embolism with serious consequences, including paralysis or even sudden death.
