it was discovered 10 weeks ago that i had a aneurysm on my ascending aorta 6.4 with a bicuspid aorta vavle. i had surgery 7 weeks ago st jude aorta valve dacron graft for ascending aorta. Four days after surgery i need a pacemaker due to the surgery. My question is there any long term risk or dangers of this that i should look out for. I take amiodarone (200mg) for a-fib that i developed after pacemaker surgery and celexa 20mg, zocor 20 mg. norvasc 5mg. coumadin 7.5mg m & w 5 mg. the other days of the week. I started rehab tues. and blood preasure went up during exercise 190/83, but went back down to 150/80 afterward. St jude valve is very loud most of the time. pulse runs around 80.
