I am 33 with Australian ATPL, I have held a Class 1 medical since I was 18, and I have a bicuspid aortic valve (BAV).
You need to have a cardiologist check it out, as there are some other genetic defects that occur with the BAV. The worst one is a weaker arterial wall material, which allows your major vessels (particulalrly your aorta) to dilate. This causes aneuysms, which of course can kill you near-instantly.
If your valve needs replacement you will have restrictions put on your licence - in Australia you will be limited to "As or with a co-pilot"
I had my ascending aorta replaced 2 years ago this week, and I still have my own BAV. I am working as a Chief Flying Instructor and I will start with a small airline in September. Life's good!
