I had the most fantastic diagnosis and care at Stanford for cerebral aneurysm surgery. Literally the best in the world. When I was diagnosed with a root and assending aorta aneurysm, I got a second opinion at Mayo PHX because I felt not the same urgency. Mayo ran a whole battery of tests in a week, then scheduled my surgery. It's July 8th. Take control of you own health. You are your best advocate. All of these Doctors are amazing, but it your life. Best of luck!
