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 mild regurgitation of the mitral and tricuspid valves severe?

Mitral and tricuspid valve regurgitation with a small amount of reflux is generally not serious if it is not associated with any related organic diseases, nor will it lead to adverse consequences, and therefore does not require any corresponding treatment. If the minor reflux of the mitral and tricuspid valves is caused by an organic disease leading to an enlarged heart, the condition is then considered more severe. It is necessary to actively identify the specific related diseases and provide appropriate treatment for different diseases to effectively control the condition long-term. This is crucial to prevent further exacerbation of the disease, which could lead to further enlargement of the heart and increased severity of mitral and tricuspid valve regurgitation. When significant regurgitation occurs, it can cause a marked increase in the preload of the ventricles, promoting the occurrence of heart failure and thereby leading to severe adverse consequences.

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 mild mitral and tricuspid regurgitation be cured by taking medication?

If a patient frequently exhibits mild regurgitation of the mitral or tricuspid valve, it is advisable to go to the hospital for a cardiac echocardiogram, as this would help to further clarify the diagnosis. If the condition is related to heart valve disease, early stage treatment can involve using medications to improve ventricular rate, or to manage heart failure, thereby reducing the load on the heart. During this period, it is still necessary to actively monitor the patient's heart rate, blood pressure, and pulse changes. If the patient's heart rate is too fast or blood pressure is elevated, these symptoms need to be actively managed using medications. Because this disease can recur, medical treatment can only improve symptoms but is not curative; regular follow-ups are still required.

Why can't vasodilators be used for mitral stenosis?

Mitral stenosis primarily restricts the return blood volume to the left ventricle. If the stenosis is particularly severe, it can lead to a significant decrease in return blood volume, resulting in poorer pumping function. There are several main factors that affect return blood volume. The first is sufficient circulating blood volume, and the second is the degree of mitral stenosis. Therefore, after using vasodilators, a large amount of blood flows into the capacitance vessels. As a result, the return blood volume decreases, which can further reduce the return blood volume through the already narrowed mitral valve, leading to worsening breathing difficulties in patients, severe cases can cause fainting, or even sudden death.

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.
