Hi,
I had double valve replacement with aortic root replacement 5+ yrs ago. I have been riding since that time off and on.
I had a cadaver valve put in the pulminary spot and my pulminary valve put in my aortic valve spot.
The procedure was called the ross procedure. (My aortic valve was faulty).
My cardiologist and surgeon supported my riding.
I was back on my bike 2 months after my surgery.
be safe keep in touch with you cardiologist as you progress.
Good Luck.
