If the patient has a history of mitral valve regurgitation, this condition can lead to changes in heart function, particularly symptoms like palpitations and difficulty breathing. If the symptoms decrease during inhalation, this might be caused by abnormally low pressure in the left ventricle or left atrium. Since this is a pathological change, it is currently recommended that the patient actively use medication and control changes in heart function. If the condition worsens, sometimes surgical treatment is advised as it can also serve a therapeutic purpose.

Will mild mitral valve regurgitation worsen?

Because mitral valve insufficiency is a type of heart valve disease and also a form of rheumatic heart disease, mild mitral valve insufficiency can be actively managed with internal medicine, thereby alleviating the patient's symptoms. However, this disease can potentially worsen, especially in cases of mild insufficiency. When cardiac function becomes impaired, it can lead to severe insufficiency. In such cases, surgical treatment is sometimes recommended for the patient. If the patient's cardiac function is actively managed, infections controlled, and regular hospital check-ups are maintained, improvement can be achieved.

Why does the pulse pressure increase with mitral valve insufficiency?

Mitral valve regurgitation leading to an increased pulse pressure difference is a very common phenomenon, which is related to the condition of mitral valve regurgitation itself. This is because when the left ventricle is in systole, the incomplete closure of the mitral valve causes the blood in the left ventricle to flow back into the left atrium, significantly increasing the volume of blood in the left atrium. When the ventricle is in the diastolic filling phase, a large amount of blood from the left atrium enters the left ventricle. At the same time, the left ventricle receives blood from the left atrium as well as the blood remaining from the systolic phase of the ventricle, resulting in a significant increase in the volume of blood the ventricle pumps. This leads to a notable rise in systolic pressure, thereby increasing the pulse pressure difference.

Can mitral valve insufficiency be treated with interventional surgery?

If the condition of mitral valve regurgitation is not very severe, interventional surgery can be considered when the condition is under control. However, if the mitral valve regurgitation is accompanied by heart failure, especially chronic heart failure, and if cardiac function is not timely corrected, the patient may not tolerate the surgery, and there are certain risks associated with the operation. Because mitral valve regurgitation can lead to the formation of thrombi, particularly causing cerebral thrombosis or ischemic cerebrovascular diseases, it is important to actively monitor changes in the patient's heart rate, blood pressure, and pulse. If conditions such as tachycardia or elevated blood pressure occur, they need to be actively managed. If the disease is timely controlled, surgical treatment can be considered.

Is mitral valve regurgitation due to incomplete closure congenital?

If the patient has a history of mitral valve insufficiency accompanied by regurgitation, it may indicate congenital heart disease, but it does not rule out rheumatic heart disease caused by other illnesses. Because of this, it may indeed be a type of congenital heart disease, and some surgical treatments can be used, which are relatively safe. During this period, it is still necessary to actively monitor changes in the patient's blood pressure, pulse, and heart rate. If there is an increase in blood pressure or an overly rapid heart rate, it needs to be actively managed. Early intervention and treatment can alleviate the current condition of the patient. Based on this situation, it is recommended to just perform a cardiac echocardiogram.

Can mitral valve insufficiency be treated without valve replacement?

Mitral valve regurgitation is classified into mild, moderate, and severe categories. Generally speaking, patients with mild and some moderate regurgitation may not exhibit symptoms. However, a small proportion of patients with moderate or severe regurgitation might experience symptoms such as tightness after activity and difficulty breathing. If these conditions recur, there may be an indication for surgical intervention. Therefore, for patients with moderate to severe symptoms, or those with significant enlargement of the heart, it is recommended to consider surgery at an early stage. If patients with mild or some moderate mitral valve regurgitation are asymptomatic and do not show significant enlargement of the heart structure, medical treatment or observation without valve replacement can be considered.
