Once you get the Bicuspid Valve(I'm assuming the Aortic Position) replaced you will have so much more energy. At 50 mine was all stiffened and not opening or closing completely. They called this condition Stenosis. Ask your Doctors about the condition status of the valve. I had and Aneurysm too but when that happened and needed surgery there was no time to do the valve. They did the valve 10 years later. I bet with you they will probably do both at the same time.
