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.

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 causes mitral regurgitation in young people?

Mitral regurgitation is a phenomenon caused by incomplete closure of the mitral valve. From a medical perspective, when the left ventricle contracts, the mitral valve should be closed to prevent blood from flowing back into the left atrium, ensuring that the blood in the left ventricle can be fully pumped into the aorta to meet the needs of the body's tissues and organs. If there is incomplete closure of the mitral valve, the blood in the left ventricle will flow back into the left atrium, affecting the pumping efficiency of the left ventricle. If it is a mild closure insufficiency, generally it is not a big problem, but if it is moderate to severe, it often easily triggers the onset of heart failure.

Can mitral stenosis be repaired?

Mitral stenosis sometimes requires surgical treatment to achieve repair standards, but it cannot be repaired solely through medication, as medications only relieve symptoms and cannot serve the purpose of treatment. This disease can cause ischemic and hypoxic changes, leading to heart failure. Patients typically present with a rumbling murmur in the precordial area, and may also experience palpitations, difficulty breathing, and other symptoms. It is sometimes crucial to actively monitor changes in the patient's blood pressure, heart rate, and pulse. The treatment primarily focuses on symptomatic relief, improving heart function, and may include the administration of low-flow oxygen inhalation to help alleviate the current condition of the patient.

Why is there a murmur during diastole in mitral stenosis?

The mitral valve is a one-way piston valve between the left atrium and the left ventricle. Generally, once the ventricle completes a contraction and ejects blood, it immediately begins to relax, at which time the mitral valve opens to allow blood from the atrium into the left ventricle. When the mitral valve is severely narrowed, the blood from the atrium cannot pass through the mitral valve into the left ventricle in a timely manner. At this time, the blood flow speed at the mitral orifice increases, forming turbulence, which results in the appearance of diastolic murmurs.
