@ontogenyx, Although I recommend checking with your cardio, I don't see singles tennis being a problem. The wood cutting and chopping might be a concern because of the weight of the saw and the maul.

I understand your impatience to just get this done, get back to "normal. But I think with your aneurysm so small, any cardio surgeon worth their salt would say NO in no uncertain terms. Cardiac surgery is serious stuff and things can go wrong -- and that is why responsible surgeons will not take a chance when the surgery is not yet necessary. If you find a surgeon who is willing to do this surgery, run the other way.

I wish you peace and continued good health.
Donna
