Mild regurgitation of the mitral and tricuspid valves, if seen in healthy individuals without related organic diseases, mainly occurs due to the physiological aging of the mitral and tricuspid valves as age increases. This results in slight insufficiency during ventricular contraction, leading to mild regurgitation. This condition is not pathological and does not require treatment, nor does it lead to adverse consequences. However, if the mild regurgitation of the mitral and tricuspid valves is accompanied by an organic disease that causes ventricular enlargement, the cardiac enlargement and annular dilation result in relative regurgitation due to the organic disease. It is necessary to actively control the underlying disease to prevent further enlargement of the heart, which could worsen the insufficiency and cause more blood regurgitation.
