Hello- Please allow me to preface this topic that I'm not wanting a debate regarding tissue vs mechanical. I realize that there are lot of conversations (or should I say biased opinions) on this subject already and I believe it is a 'personal' decision for choosing a particular valve type over another. That said, I'm merely looking for additional feedback from those that have received or can provide additional insight regarding the Medtronic Mosaic or Edwards Resilia valves? Unfortunately, I have found limited information via the web for either one. Thanks in advance!
