Mild aorta regurgitation on echo. Norm leaflets no stenosis. LV norm size and function. No symptom. Can I go back to aero. Exercise? Cause of regurg?

Aortic valve. In these situations unless there is any other reason we do not limit aero type exercise, but I recommend against very heavy exercise such as weight lifting, most other sports are OK, reason is calcification in aortic valve in most cases at your age, but you should ask that to your doc .
