Hi, My son has had 5 OHS and a few other heart related surgeries, his 3rd was when he was 10 and 5th when 19 he is now 25 so I spoke with quite a few surgeons about the risks etc, especially since we knew going into both his 4th and 5th OHS that his heart was fused to his sternum, (luckily for you most people who have higher risk of that and opening problems are people like Justin who have a pulmonary conduit because it is on top of the heart, right below the sternum) so would be even more riskier than the normal REDO, but we discussed stats, safest ways to open him, back up plans, stats on MULIPLE REDOS in general (In the hands of experienced surgeons who operate on multiple (over 3rd) REDOS daily if not weekly.
The surgeons and centers that have the most experience in multiple REDOS are of course the CHD and adults with CHD surgeons since thousands of children are born every year who need 3 OHS before they are in grade school. They now have over 25 years experience in the best ways to open and operate on the most complex surgeries needing 3 or more surgeries.. so even tho there IS risks, in their hands the risks of morbidity and mortality is about the same for 3rd and 4h OHS as first. REDOs ARE tougher for the surgeons, but for the most part IF they run into a problem they know with out stopping to think the best way to proceed both in the OR and during recovery. Justin had a few bigger problems post op, but even from the 2nd surgery in 89 to the third in 98 I saw so much better outcomes and problems that were common in the 80s, like the bad pericardial fluid Justin was in and out of the hospital for 6 months after his 2nd surgery, was treated much quicker then. Things got even better by his surgery in 2005. After he recovered even when he had complications, things are great. OF Course there is always a risk to any surgery and there will always be people who don't survive or have life long complications, luckily the chances are VERY good for a full recovery.
There are quite a few articles/ studies like this one

I know you live in Kuwait but had your baby in Boston I believe, where are you considering having your valve replacement? Who /where did you have your first 2 surgeries? IS that surgeon still operating? I think it is always good to have the surgeon who did earlier surgeries so knows exactly what they did do the next IF possible. BUT as long as you go to a surgeon who specializes in CHD and adults with CHD (for the most part they are in Childrens Hospitals) the chances of not only surviving but having a complete recovery and thriving are very very good.
The top Hospitals in the US (and maybe the world?) for Congenital Heart defect surgery are Boston Children hosp and CHOP (Childrens philly) There are a few other very good CHD centers in the US, but Boston and CHOP usually rank 1 and 2. Not only do the surgeons operate on Children and young adults having 3rd or more OHS a few times a week but the dedicated staff know what to watch for and how to take care of any post op problems. When Justin needed his 4th OHS we went to both centers and the surgeons had no doubts he would have a full recovery and altho Im sure they would prefer not to have to operate on a chest that has been opened multiple times, they pretty much said they would just go slow and careful opening him and removing his older conduit (graft) as well as other things like possibly putting him on the heart lung machine before they had his chest fully open since they knew his heart was fused to his sternum. None of them said they wouldnt operate or the risks were too high etc. We eventually chose CHOP over Boston mainly because it was 20 min from home and Boston was 5 hours. Since Justin had a history of running into problems after he was home, we felt better being closer to the surgeon and staff who operated and took care of him if he had to go back.
Here is a link to one of the well respected rankings of hospitals , this is for CHD
http://health.usnews.com/best-hospitals/pediatric-rankings/cardiology-and-heart-surgery FWIW the top ranking for aduls heart hospitals is different, even tho 'adult" heart hospials do many AVRs and repeat AVRs, for the most part they are not the surgeons who have the MOST experience w/ people having multiple REDOs.
I'm sorry I dont know which hospitals or surgeons in other parts of the world have the most experience w/ Congenital heart patients. Are you being seen by a cardiologist that specialises in Adults w/ CHD? If so they would probably be able to reccommend the best centers. Also beside the forums here you might want to look into the ones at the Adults with CHD org
http://www.achaheart.org/ Quite a few members there have had multiple REDOs there is also an org in the UK that has a good forum I dont know the link off he top of my head but I believe it is GUCH or growing up w/ chd, they could let you know more about hospitals there.
I understand why you would choose a mech valve for your 3rd heart surgery at your age, the one thing I would consider is if you plan on or want any more children. Even tho it IS possible to get pregnant and carry a healthy baby w/ a mechanical valve and coumadin, or other anticoagulants, it usually is recommended to get a tissue valve if you plan on having more children, since it IS a higher risk pregnancy with risks to both the mother and baby. YES if you did choose a tissue valve it will need replaced. and at your age the chances of it lasting 15-20 years is probably close to 0. Even tho there are pretty good chances when you did need that valve replaced, in probably 10 or so years, since it would be your 4th OHS, you most likely would be a candidate to have it replaced by cath, since they are succesfully doing them on high risk patients right now. You still are signing up for at least 1 more OHS and the risks that go along with that. On the other hand, you most likely would have another 10 plus years w/ out Coumadin or other anticoagulant and the risks that DO go along with that.. even today with the best valves and home testing there still ARE risks of clots and bleeds.
Saying all that, since this will be your third surgery and you are in your 20s, unless you do plan on having more children almost everyone would reccomend getting a mechanical valve now. I just wanted to bring up children incase it is something you have to think about
I forgot to answer in Justin's case as far as time in the hospital post op and complications his 3rd and 4th were the best, he was home 5 days or less for his last 3 and didn't have any post op complications for his 3rd and 4th surgery. His 5th he was also home in 4-5 days post op but was readmitted 10 days post op for an infection, which could have happened after any surgery.
Good Luck with everything and take this time to enjoy being a new mom.
