So I'm going to tip toe in here. I've been watching this site since I was diagnosed with severe Aortic Stenosis, about 6 weeks ago. It was difficult trying to translate all the acronyms and medical jargin, but I've slowly started to catch on. My initial perceptions here were that "mechanical good...bio bad" and I this only served to confuse me more. It's been recommended to me to seriously consider bio because of my 71 years on this planet. But then comes the "they're only good for 5 years", and other negative feedback.
Duffy, Paleowoman, john b, MartinF, Et Al, has given me great hope and helped greatly to settle my fears and confusion; it means a great deal to me. Tomorrow, I meet (for the 1st time) my referred heart surgeon; and I'm praying for God's guidance on what to ask and how come away confident in what my next steps should be. But the main takeaway from all this is, now, I feel I can give bio an honest consideration; you've all given me great confidence on judging both mechanic and bio equally.
PS To EVERYBODY who posts in here, I've learned soooo much, with the links to medical reports, personal experiences, etc.; thanks to all of you for helping me wade into this with more knowledge.
