I think your statement implies if you are healthy 56 year old - as I am - that you'd be stupid not to get a mechanical valve. I am not a rocket scientist, but my no means am I stupid either.
So to me, going tissue make more sense and I can avoid coumadin - hopefully.
Sorry, I did sound a little blunt. But I did have a bad experience from AVR.
Warfarin was no big deal to me. My wife had been on warfarin for a year due to blood clots in her pelvic area. So I had no fear of warfarin.
The doctors were concerned about me going on warfarin due to having a severe bleeding duodenal ulcer the year before. But even with a history of a bleeding ulcer, they didn't want to use a pig valve. I hadn't gave it much thought as far as what kind of valve. Or much though about having to repeat surgery. (I wasn't on the internet back then)
At that time I didn't think valve surgery was too big a deal. From what I'd heard, most folks went home within 5 days. Heck, I felt could take anything for 5 days. Had I known then, how my surgery would go I would have
demanded a mechanical valve! Yes, I saw men 20 years older than me going home 5 days after AVR. Complications from valve surgery was rare, even 18 years ago. I spent a total of 7 days in ICU and 20 days in the hospital. It took a full year to get back where I was before surgery. But I feel very lucky to have been in a hospital that could deal with complications. I owe the doctors and hospital my life.
I also think anyone that has had complications during valve surgery will feel similar when it comes to type of valve.
I know those of you on ACT don't find it to be that much of an inconvenience, but I think with my passion for travel and eating different cuisines and local foods everywhere I go that doesn't fit well with my lifestyle.
As far as food, I eat the same food I did before warfarin. My INR swings, probably due to my eating but that's no big deal... the dosage can be adjusted. As far as travel... we were on the road in a motorhome before and after surgery for several years. Now days it's several cruises a year and road trips. We have 2 cruises booked in the next 4 months.
I can't think of taking more risk of another surgery due to food? But that's your choice and I wish you the very best and hope your valve last your lifetime.
