Well, you know you've got my vote. My original cardio wasn't even considering a surgical option. Then, when the interventional cardio did my cath on Monday, he advised against the surgery set for Tuesday. The surgeon stuck by me, although it put him out on a limb a bit. Results of the surgery were that the valve was in extremely bad shape, and absolutely needed to come out. All that would have happened from waiting would have been further collateral damage to my heart.
By the way, it was my second surgery, too. If you've had it before, you know what you're up against. You're already more informed about the surgery than your cardiologist.
Again, nothing else in your heart can improve until the basic problems are corrected. There is no prescription or monitoring that can fix or even slow the progression of your valve problem. As far as surgical chances, the better condition you're in to start with, the more successful the outcome is likely to be.
Cardiologists are almost always negative on surgery. They somehow seem to think that, 1) it means they failed to "manage" your heart issues and that, 2) a 2% chance of something going wrong is somehow better next Thursday than this Tuesday, and that, 3) if something goes wrong in the surgery someone will somehow blame them for it.
Most cardiologists are dealing with many upper 70s to mid-80s patients, and they tend to just manage their heart issues until the patient dies of something else. However, when you're younger, you actually want the problems fixed, so you can hopefully enjoy the rest of your life. I fully believe my original cardiologist would have kept "monitoring" my heart until it was desperately weak, then would have said something like, "Well, I'd refer you to a surgeon for a valve replacement, but I'm afraid your heart might not be strong enough for the surgery."
Frankly, trying scare tactics about surgery on a patient who will obviously have to have the surgery later anyway is cowardly. And how handy, should something go wrong, to later be able to say, "I tried to talk him out of it."
You may wind up needing to wait until either your valve is less than 1 cm² or your aneurysm is greater than 5cm. Those are general guidelines in the US for surgery. But it looks like you are very close to that anyway.
I wish you good fortune with moving ahead, and success with your surgery.
Best wishes,
