That would be valvular heart disease which includes aortic stenosis, aortic regurgitation, mitral stenosis, mitral regurgitation, in any combination, either pre- or post-operative.
I would like to hear of your experience with it.
No links please. I have the pertinent literature ensconced on my iPad. And no medical advise, either. As my cardiologist said, "I'm sorry, your days of competitive cycling are over". "Doc, my days of competitive cycling never started".
But I would love for you to share your travails, if you would.
