Hi and thanks for the query,
The results of the echocardiogramme showing a mild leakage, with normal clinical and electrocardiographic findings is actually very reassuring. Even asymptomatic or normal individuals could have mild leakages. It becomes a problem only when the leakage becomes relatively too much and when clinical signs and symptoms set in.
The main thing you got to now is follow directives of your treating physician and do regular annual control cardiac ultrasound
. Any unusual feeling like tiredness/cough/chest pain/breathlessness or whatever should cause you to indicate this to your family doctor.
Thanks and best regards,
