Moderate mitral regurgitation can be treated medically without surgery. If medication is not effective, people who meet the indications for surgery should have timely surgery. Moderate mitral regurgitation has a regurgitation fraction of 30-50%, at which time symptoms such as chest tightness, chest pain and shortness of breath can occur. Moderate regurgitation can be treated with appropriate medications according to the cause of the disease. If it is caused by infective endocarditis, you can follow the doctor’s instructions to take penicillin, cefdinir, and other medications to fight infection. If accompanied by heart failure, you can choose spironolactone, furosemide and other diuretics to correct heart failure. If it is combined with arrhythmia, digitalis can be used as prescribed by the doctor to fight against arrhythmia. However, if mitral regurgitation is accompanied by chest pain, shortness of breath, and coughing up pink foamy sputum, timely surgery is recommended. Currently, the surgical procedure for most cases of simple mitral regurgitation is mitral valvuloplasty. Mitral valve replacement is considered when the mitral valve fails to form, or when the mitral valve fails to form, or when there are serious complications such as hemolysis. Such cases should be treated promptly and in accordance with medical advice.
