First of all I'm on an expert but having had mine repaired by a guy who was considered an expert in the field of aortic valve repair, Dr Joseph Bavaria, I asked him a lot of things and picked his brain pretty good. Plus like most people these days I did a lot of my own research. I guess the best answer is it's hard to say and depends on a lot of things mostly the condition of the valve and what kind of valve it is. I think there's another threat out of here that goes into detail on it but There are what they call Sievers 0 ,1,2 or unicuspid. And even within those categories there's differences with geometry, the positioning of the coronary arteries, the condition of the leaflets, calcification etc. I was 80% set on getting a mechanical because the cause for my surgery was an aneurysm and I wanted to have a one and done. However since I had no calcification and I had a pretty rare sievers 0 which means I have to equal size leaflets and my gradients were great and I only had trace leakage ( which somehow in my latest echo shows up as no leakage, which I'm okay with) I ended up getting my aneurysm replaced and the valve repaired. I specifically told him I didn't want him to do this if he wanted to as a challenge for himself and I only wanted a repair if once he was in there doing it he thought it might last a lifetime. I was 45 at the time of the surgery so I made it clear to him that I considered a lifetime at least another 40 years. Apparently he came out of the surgery very excited and animated and told my mom and wife that I would never need it operated on again. Now obviously I don't take that as a certainty in any way and I worry about the future surgery but having done my research and asked the questions and made clear how I felt I ended up going with the expert.For those who chose repair, what do the tell you is the likelihood that it will last (and how long) or need additional surgery down the road? Having gone through one OHS I can tell you that for me, I would not willingly do it again. So I have to think if I was forced to make that choice I would opt for replacement rather than repair. But thats only because I already know what its like to experience the surgery and recovery... whereas most in that scenario do not
I think it's important that for whoever is contemplating repair they have to ask themselves what they want out of it.
