Thanks for your help and your best wishes.
With your history I don't think so ,,,,, you are evidently in quite good health and this may well prevent another problem in the future at which time you will be older and perhaps not as good a candidate for the preferred treatment. You seem to have a problem about every 10-12 years .... you'll be in your 80s should you have another problem and perhaps not able to tolerate what is required. I'd certainly "go for it"; this could mean "no more worries". Best wishes for a speedy and uneventful recovery !!
