Thank you for your help. It is new in the US. I have many questions aboout the benefits and recovery. I live near the Houston Texas Medical Center and referred to a physician there. I am hopeful that my exercise tolerance will increase. I am still quite young with lots to do. Let me know if you see a good website for info.
I haven't had the procedure done, but I do have to correct you on something. The procedure is not really new, it has been performed in Europe since 2002. The USA basically watched the progress with anticipation before adopting it, and after trials in 2010 with over 300 patients, they found there was a 20% improvement after 1 year over surgery. I suppose the procedure could be called new in the USA, but the people doing it would have had very good training.
