hey,
I have a BAV, with regurg and insufficiency, as well as mitral stenosis with insufficiency (see signature). I think if he is symptomatic at all he should wear one. I thought about it, and put it off, and thought about it, and put it off, I was becoming more symptomatic this past summer, and finally decided to get one because of my symptoms. I ordered it one morning, and that night I passed out at work. it was freaky. nothing came of my spell, I came too within a minute or two. if I had been found by one of my co-workers I would have wanted them to know what to do, and would have wanted the EMS team, and the hospital to have the info that I have printed on my bracelet, and on my medical alert info in my wallet.
just food for thought
