Acute and chronic mitral regurgitation, as well as the severity of the symptoms of different treatments, mainly including follow-up, drug treatment, surgical treatment and so on. 1. Acute mitral regurgitation: When acute mitral valve insufficiency leads to regurgitation, vasodilators such as sodium nitroprusside are generally applied to control symptoms, and mitral valve repair or replacement is performed urgently or on an elective basis. If the regurgitation is accompanied by hemodynamic instability, intra-aortic balloon counterpulsation is feasible. 2. Chronic mitral regurgitation: If there are no obvious symptoms, regular follow-up can be done to prevent rheumatic fever and infective endocarditis. If symptoms are present, angiotensin-converting enzyme inhibitors such as captopril can be used to relieve symptoms, and mitral valve repair or mitral valve replacement can be performed if necessary. Patients are advised to consult a specialist to choose the appropriate treatment according to their condition, and medications need to be used under the guidance of a physician.
