Just my thoughts...
The symptoms often aren't easy to spot on yourself. Most people who have them don't accurately recognize them. Fatigue, arrhythmias, shortness of breath earlier than you used to get it are all easy to ignore or to put down to age or a need to exercise more. The problem is that they creep in slowly, rather than just showing up (except maybe for the arrhythmias). Sometimes, people don't realize they had symptoms until they go away after the surgery. The arrhythmias tend to be PACs and PVCs, that are relatively harmless, but scary and sometimes somewhat painful.
Angina is also tricky. From TV and the movies, we have a vision of someone clutching their heart and collapsing in agony. Well, the pain often isn't at the heart - it may be in the arm or back, or more commonly like a sudden lump at the top of the throat, or the feeling at the top of your lungs that you've been running in freezing weather (when you haven't). In women, it's not uncommon for it to show up as jaw pain - dentists are fairly aware of it. It doesn't show up every time you exercise, and it doesn't always require exercise to show up. And it doesn't usually cause people to collapse. It often hurts a bit, but in ways you could ascribe to something else. You can generally walk and do normal things while you're having angina. It doesn't mean you're going to die right then (or even soon), but it's your heart's way of talking to you.
The "moral limit" for aortic opening size is 1 cm². Anything below that size is defensible for surgery. More recently, a percentage of cardiologists have been holding people to much lower limits: .8, .7, even .6. While this may be acceptable in many cases for much older patients, my personal bent is that it's not appropriate for a younger, more active patient. Such a small opening could potentially be more detrimental to someone of your age and activity level, and be responsible for more damage and enlargement to the heart, perhaps even some level of heart damage that remains after the surgery. The better the condition of your heart before surgery, the better the likely condition of it afterwards, and the more likely a swifter recovery. As cardiologists don't often treat younger patients for this, I think they get the mindset that you're older and less active than you may actually be. You will find much of the information and even the recovery instructions tend to be geared to the more common, elderly patient.
Many cardiologists are also reluctant to send patients for surgery because they are uncertain of the risk of waiting, but they are certain that the risk of surgery runs 1%-2% in a good, but untried patient. They seem particularly reticent to send a younger patient to the table, even as the risk of collateral heart damage from waiting too long begins to rise.
That's not to say at all that you should get surgery as soon as you're below 1 cm². First off, echoes aren't that accurate, and it may not be a correct reading (they're often off by a point or even two). Also, most people seem to tolerate smaller sizes than that (.8 cm² sounds like a good compromise) without any permanent damage. It just means you should be very aware of your left ventrical size and any other abnormalities that your heart displays, and if you become truly concerned, you know you're in the moral ballpark for a thoracic surgeon. If you become truly concerned with the delay, and feel that you seem to be headed for permanent heart damage, you should be talking to a surgeon for another opinion. Your body will likely be sending signals (symptoms) if this is the case.
As far as the Ross Procedure, there seem to be excessive issues with bicuspid hearts getting RPs, as the self-donated valve often has some of the same tissue issues as the original, and has a higher percentage of failure than a valve from a non-bicuspid RP recipient. Surgeons with a great deal of experience are more apt to make a good choice. However, the younger the patient presents, the more likely it is that tissue problems exist at some level. The risk, as stated earlier, is that you wind up with an extra surgery, more scar tissue and two valves that need to be monitored, instead of one. You should discuss the RP option very carefully with your surgeon.
Best wishes,
I'm not waiting to "pass" out. Sorry. She did assure me that the rest of my heart looked good so I am guessing that it's not enlarged or damaged.
