Question
Is it always necessary to undergo surgery for mild mitral regurgitation, whether it’s organic or physiological?
Answer
Mild mitral regurgitation can be categorized into organic and physiological types. For physiological mitral regurgitation, if the patient shows no symptoms and there is no change in heart size, long-term follow-up observation is required. However, if the patient experiences worsening of mitral valve insufficiency, cardiac function weakening to 3-4 levels, or no significant improvement in cardiac function after internal medicine treatment, accompanied by obvious clinical symptoms, and the echocardiogram shows continuous expansion of the left ventricle, decreased ejection fraction, such as when the left ventricular end-diastolic diameter exceeds 50mm or the end-systolic diameter exceeds 70mm, and the ejection fraction is below 50%, then active consideration should be given to surgical treatment.
