Ani,
? If the anatomy was favorable, I wouldn't mind having an ATS band.? You've been reading HSF long enough to realize that my views have evolved a bit.? 
? I appreciate your opinion of my approach to questioning experts at meetings.? Number one, I'm generally respectful but not afraid of them.? Frankly, now that I'm getting to be in the early stages of "old fartism", I've got as much or more experience than a lot of them.
? I'm really looking forward to the Leipzig meeting, though it will be a bit intimidating talking about AF surgery right after Jimmy Cox's presentation.? I'll let HSF know how it goes.? It'll be great to see Roberto, hopefully Prasanna, as well as your boss, Dave Adams.

Hal

I take it by extension that if you needed a mitral today you would vote for an 
ATS band....mmm

Looking forward to hearing your views in Leipzig - hope you give the 
single-theme evangelists and dinosaurs a hard time as you usually do. I have 
heard you question the experts and evangelists several times and have no doubt 
that you always speak for what you see as the best regardless of which direction 
it comes from. I have also seen your views change over the years as new 
understanding and experience emerges. The meeting has some weird stuff on as 
usual - thankfully no mitrofast this year, but by your analogy would anyone 
really want a sutureless AVR placed open in their loved ones? Well hopefully 
someone will stand up and ask the ethics of such demonstration!

Just to complete my thoughts.? For those who might think my previous posts 
indicate I'm some kind of shill for Edwards, do know that I haven't implanted an 
Edwards mitral, either porcine or pericardial, in years.? For mitral 
bioprostheses, I prefer the SJM Biocor due to its low profile.? I use ATS bands 
for my mitral robotic cases.? In my opinion, the best policy to use in 
determining what you use is what you would prefer to have implanted in you or 
one of your loved ones.> > Hal> > > -----Original Message-----> From:
