Considering Radvitch Proceedure at 79

Background from a previous comment: I have a Haller Index of 3.4-3.7, 79 years, a long history of breathing impairment and lack of endurance. I also have a dilated ascending aorta at 4.6mm that seems pretty stable and a myocardial bridge.

I visited with Dr Richard Shemin cardiac surgeon this week and asked his opinion regarding complications that may arise in the event of needing heart surgery for my dilated ascending aorta if performed either before or after a Radvitch procedure. He didn’t seem to think it made too much difference...if anything he expressed that the surgery would be easier operating without bars or prior surgery.
His opinion was that all my tests were testing out satisfactorly and I should not go ahead with the pectus surgery. He referred to my notes from my visit woth Dr Cameron’s as being ambivalent about the benefits of surgery and expecting only a 10-20% gain.

I brought up the point that led me to consider surgery in the first place, namely a very noticeable difficulty with normal breathing and concern about the progression of this difficulty. I was reminded that my stress test was good as was my pulmonary test.

After a great deal of consultation and research, I’m still on the fence. I had a ventral hernia repair around two years ago with an easy recovery so I would feel comfortable with the benefit of Dr Cameron’s expertise even at my age. If anyone else reading this has knowledge of anyone's advanced age recovery from Radvitch, I'd be very grateful to hear.
