Hi hx77 John - I can give a comment on this because I have been seeing a cardiac surgeon (seen two over the past few months actualy) since I had my bicuspid aortic valve replaced just under four years ago. Because of the small size of my replacement valve I have "moderate patient prothestesis mismatch", which has resulted in me developing some symptoms and never getting back to how fit and well I was prior to surgery. The question of doing redo surgery to do various things to put in a bigger valve at this point in time has been discussed. Both surgeons have said that to do so now would carry a high risk of mortaility, particularly due to scar tissue I understand. I don't think that the mortality risk gets less leaving it, I think the mortality risk might get greater due to increasing age, but they would wait until the risk of not doing redo surgery is greater than the risk of doing it.hx77;n880531 said:Better to do second OHS in 15 years than in 5 years after first OHS. (I am thinking the other way around. Could someone explain to me the logic?)...<snip>...Could someone comments on the risk of second OHS? Specifically is it riskier to do it early vs late?
PS the new generation of Inspiris Resilia valve should last as long as a mech valve so more than 15 years (your last paragraph above) - that's why in the UK they have inserted that one in a patient in her 20s and another in her 40s and they expect the valve to last. Of course only time will tell but that's how it is being marketed by Edwards.
