Patient's question:
Mitral valve regurgitation can be classified as either organic or functional. Does mitral valve regurgitation require surgery?Doctor's answer:
Mitral valve mild regurgitation is classified as either organic or physiological. If it is physiological, the mitral valve exhibits chronic, long-term mild regurgitation, with the patient remaining asymptomatic and no changes in heart size. Long-term follow-up is required. Additionally, some patients may experience worsening mitral valve insufficiency, while others may develop declining cardiac function to the 3-4 grade level. In some cases, despite active medical treatment, cardiac function does not show significant improvement, or there are prominent clinical symptoms. Auxiliary examinations, particularly echocardiography, may reveal progressive left ventricular enlargement, reduced ejection fraction, and if the left ventricular end-systolic diameter is >50 mm or the end-diastolic diameter is >70 mm, and the patient's ejection fraction is <50%, surgical intervention should be actively pursued.
