I am so very sorry that your thread got so off topic! You did not start anything, but apparently no one here at that time was able to offer any insight to the myocardial resection, including myself, as I've never had that procedure done.
Please accept my apology and perhaps we'll hear from someone else. This is a fairly rare procedure from what I'd read, so maybe it will take a while to hear from anyone.
I wish both you and your husband all the best and hope this procedure has helped offer him more quality of life.
Much good luck and best wishes, Teri
