Hi there,
It depends on which valve is leaking.
The Aortic valve needs replacement, sooner than any of
the other
valves. Normally valves takes a long time to deteriorate and moderate regurg should still be checked with annual echo's.
You become a candidate for surgery when your heart function deteriorates, heart enlarges, low LVEF, signs of heart failure or pulmonary hypertention. The leak is graded from 1-6. That is the amount of blood pumping back into the Atrium.
