I have one of these. It was picked up during a medical examination when I was 27, although, according to my cardiologist, I´ve had it since I was born and nobody noticed it up until then.

Ask your cardiologist if there are any reasons to be cautious and anything to be aware if in your particular case. Mine told me to do anything and everything that I usually do and just to go to her for a checkup every few years.
