Firstly, let me express my disappointment at you guys scaring off hevishot, rather than encouraging him to express himself openly.
Shah, the three biggies are St Jude Regent, ATS, and On-X.
The ATS has a rep for being quieter.
When I first met my surgeon in 2013 he told me he puts in a lot of Regents. He had only started using the On-x. When he operated on me 6 months ago, he had put in a few more On-X and liked them.
The On-X has a design feature that makes pannus (scar) growth less likely. You can read the blurb, by clicking on the banner on top of the forum. I still run on an inr between 2-3, despite the lower inr claims. I really see no added benefit running lower. Don't want to sound like a shill. There's lots of info online about the risk factors. Even wiki has some good info.
if YOU decide on a particular valve, ask your surgeon if he has experience installing your choice.
You will probably click, but after six months you won't even notice it. As we get older our ability to hear higher frequencies reduces, so my kids can hear it, my parents can't. Just letting you know, so there are no surprises. My clicking has become a 'meme' and has even featured in 'rap battles' (little fokkers trolling me).
You'll do well. Most people don't know what an ohs scar looks like, so they'll think you're a badass at the beach. Enjoy your youth. It only happens once.
