Can mild mitral valve insufficiency heal itself?

If the patient is younger,

mild mitral insufficiency

may be caused by incomplete mitral valve development. With the passage of time, the mitral valve gradually develops and can generally heal itself. If the patient is older, this condition may be caused by leaflet abnormality, annular enlargement, chordae tendineae rupture, papillary muscle abnormality, etc. Over time, the above causes cannot disappear by themselves, so the mitral valve cannot return to normal by itself.
