Hello there @snocalfritz, and welcome to Mayo Clinic Connect.
Wow...you have a heart history for sure!
I am so sorry that you have now experienced yet another set of heart issues to deal with. No wonder you are so frustrated. There is only so much we can control, and doing your best by being active is so proactive...and now this!

I have posted a link above to an older discussion, but it may still be relevant to your seeking information.
I am curious...do you also have HCM? Hypertrophic Cardiomyopathy? This is the support group for all things HCM and HCM with obstruction.
When do you see your doctor again?
