Mitral valve insufficiency leads to left ventricular hypertrophy. This occurs because when the mitral valve does not close fully, the contraction of the ventricles often causes the blood in the left ventricle to flow back into the left atrium, resulting in a significant increase in the blood volume of the left atrium. When the ventricles relax the next time, the left ventricle receives a large amount of blood from the left atrium, as well as the remaining original blood. This causes a significant increase in the capacity and load of the left ventricle, and over time leads to enlargement and hypertrophy of the left ventricle. This condition eventually leads to the appearance of symptoms of heart failure, causing the patient to repeatedly experience difficulty in breathing.

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 regurgitation be detected by imaging?

Mitral stenosis is a type of heart valve disease. It may be congenital heart disease or rheumatic heart disease, depending on individual differences. It is recommended that patients go to the hospital for a cardiac ultrasound to confirm the diagnosis, as X-rays cannot differentiate between mitral regurgitation and mitral stenosis. This condition requires a cardiac ultrasound for diagnosis. If patients experience symptoms like palpitations, chest tightness, or difficulty breathing during this period, these issues need to be actively managed. Generally, positive inotropic agents are used to alleviate the current condition of the patient and achieve relief, while also ensuring regular follow-up visits at the hospital.

Mild to moderate mitral valve regurgitation treatment

"Mild to moderate mitral valve regurgitation has been detected, and treatment should be given based on the specific circumstances. If it is simply mild to moderate mitral valve regurgitation without related structural heart disease, it can be temporarily observed without special intervention, and regular follow-up echocardiograms should be scheduled. If mild to moderate mitral valve regurgitation is accompanied by structural heart disease, active treatment of the related heart disease should be pursued to effectively control it. If heart failure occurs, active treatment for heart failure should be initiated to prevent the worsening of mitral valve regurgitation due to aggravated heart failure. Therefore, if mild to moderate mitral valve regurgitation is present, the cause should be further investigated and treated accordingly based on the different causes."

Is mild mitral valve regurgitation serious?

Mild mitral valve regurgitation, as the name implies, is mild and not severe. From a medical perspective, most cases of mild mitral valve regurgitation are normal physiological phenomena in the human body, which do not cause symptoms, do not affect health, and do not require treatment. Therefore, there is no need to overly worry about this condition in daily life. Of course, maintaining good lifestyle habits is necessary, such as exercising regularly with activities like running and practicing yoga, not smoking, not drinking alcohol, ensuring good sleep, and keeping a pleasant mood. Regarding diet, eat less spicy and greasy food and consume more vegetables and fruits. Good lifestyle habits can effectively prevent the worsening of mitral valve regurgitation.

Why does mitral regurgitation decrease during inspiration?

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.
