Because mild regurgitation of the mitral and tricuspid valves is a type of heart valve disease, if it is not very severe, it can be observed for the time being, and some medications can be used to alleviate the symptoms.

Currently, the treatment of this disease is mainly symptomatic. It is also important to monitor changes in the patient's heart rate, blood pressure, and pulse. If the patient experiences chest tightness, palpitations, or difficulty breathing, some cardiotonics and diuretics can be used to reduce the cardiac load and thus improve the patient's symptoms.

If it is a mild regurgitation, regular cardiac echocardiography checks are sufficient. During this period, it is still important to actively prevent upper respiratory tract infections.

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.

Mild regurgitation of the mitral and tricuspid valves, what's the cause?

Mild regurgitation of the mitral and tricuspid valves, if seen in healthy individuals without related organic diseases, mainly occurs due to the physiological aging of the mitral and tricuspid valves as age increases. This results in slight insufficiency during ventricular contraction, leading to mild regurgitation. This condition is not pathological and does not require treatment, nor does it lead to adverse consequences. However, if the mild regurgitation of the mitral and tricuspid valves is accompanied by an organic disease that causes ventricular enlargement, the cardiac enlargement and annular dilation result in relative regurgitation due to the organic disease. It is necessary to actively control the underlying disease to prevent further enlargement of the heart, which could worsen the insufficiency and cause more blood regurgitation.

Lifespan after mitral valve surgery

Mitral valve surgery includes mitral valve repair and mitral valve replacement repair. The life expectancy after mitral valve surgery is directly related to the patient's preoperative heart function. Patients with poor heart function or poor physical condition have worse prognoses after surgery. If the preoperative heart function and cardiac quality are good and the surgery is timely, the prognosis can be good, even reaching normal life expectancy. Conversely, if the preoperative heart function is poor and the overall physical condition is not good, the prognosis tends to be worse due to the patient's physical state. In general, the earlier the detection and the more timely the surgery, the better the prognosis. Therefore, if there is any growth, it is necessary to seek medical attention promptly.

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 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.
