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.

Why does mitral stenosis cause enlargement of the left atrium?

Because mitral stenosis can lead to changes in the mitral valve, particularly causing excessive pressure in the left ventricle, this excessive pressure can lead to enlargement of the left atrium, which are complementary conditions. During this period, it is still important to actively manage the condition, using medication treatment. If the area of stenosis is relatively large, surgical treatment is needed, as balloon dilation can currently be used to alleviate this condition. Early treatment is best to relieve clinical symptoms. At the same time, it is also important to actively monitor changes in heart rate, blood pressure, and pulse, so as to control the heart rate and reduce myocardial oxygen consumption.

Is mild mitral regurgitation a disease?

Mild mitral regurgitation can be caused by diseases or it can also be seen in healthy individuals. In healthy people, as age increases, the valve may experience some aging, leading to mild regurgitation. This mild mitral regurgitation is not considered a pathological condition and does not require treatment. Of course, mild mitral regurgitation can also be seen in some organic heart diseases, most commonly due to heart enlargement caused by various diseases leading to relative mild mitral regurgitation. For mild mitral regurgitation caused by diseases, it is important to effectively treat the related diseases to maintain stability of the condition, to prevent the disease from worsening and causing the heart to enlarge further, leading to more severe mitral regurgitation.

Why is the hemoptysis in mitral stenosis dark red?

Since mitral stenosis is a type of congenital heart disease, it could also be rheumatic heart disease. When mitral stenosis occurs, the patient mainly coughs up pink, frothy sputum because the blood at this time is dark red. Before gas exchange occurs, a person's arterial blood exhibits ischemia and hypoxia, so the blood coughed up in this state is definitely dark red. If these symptoms persist, I personally suggest going to the hospital for infusion therapy. If necessary, some hemostatic drugs should also be used to control the symptoms.

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.

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.
