The Cleveland Clinic performs some 5000 open heart surgeries per year and being a referral center, a fair amount of those surgeries are complicated, redo operations. There is no connection of the aneurysm with the defibrillator, but there is a probable connection between the aneurysm and the Tetrallogy as well as the hypertension. The defibrillator has no effect on your risk and or recovery from aneurysm repair, however your prior surgery does effect your risk of repair, but as implied above, the greater the experience of the surgeon performing your repair, the lower your risk. Good Luck and write back if you need anything further clarified, meanwhile I will attempt to seek out more US heart hospitals that have the kind of experienced surgeon that you will need. I hope this information is useful.
