Moderate mitral regurgitation is mainly caused by diseases such as mitral valve prolapse, infective endocarditis, and rheumatic heart disease. Patients may experience symptoms such as chest pain and dyspnea, which can usually be treated by using medication and surgery.
1. Mitral valve prolapse: Prolapse of the mitral valve to the atria or ventricles, and misalignment of the valve leaflet closure can lead to regurgitation. Generally, beta-blockers such as metoprolol can be used to relieve symptoms such as chest pain and dyspnea, and it can also be treated by mitral valve replacement.
2. Infective endocarditis: Bacteria attached to the mitral valve will destroy the valve tissue and lead to regurgitation. Patients can be treated with antibiotics such as amoxicillin, cephalosporin, gentamicin, etc. Valve replacement can be chosen for those who are not effective in drug treatment.
3. Rheumatic heart disease: Inflammation caused by rheumatism can lead to thickening of the valve and relaxation of the valve ring, thus leading to regurgitation. Patients need to rest more, intramuscular injection of penicillin to control streptococcal infection, severe symptoms can choose heart valve repair or valve replacement.
It is recommended that patients seek treatment as early as possible and actively cooperate with doctors to prevent the development of the disease and affect the treatment effect.
