Hey there. I'm a survivor of a complete Type A ascending aortic arch dissection. You're going to be fine. Just stay on top of your cardiologist and get a second opinion from a thoracic surgeon who has done lots of aortic repairs. Look for someone with gray hair. Depending on the current size of the aneurysm, they may just watch and wait. Otherwise, if they recommend surgery do it. You won't get the chance to do it is you have a complete dissection. I dissected suddenly at 50 years old. I barely survived and it was a real personal, medical, and professional disaster. If I knew in advance what was coming I would have done the surgery 100 times out of 100. For you: Just relax. No smoking, drinking, heavy lifting or running for now until you know where you're at. I am 9 years post-surgery and I am thankful for every day I have had since June 28, 2015. You're in good hands, but make sure you push your doctors to get appointments and stay in the city--don't get on any long-haul flights or go to the Boundary Waters right now. Stay within 30 minutes of Mayo or a Mayo-like facility where you live. An aortic dissection is incredibly painful and feels like someone is peeling the skin off of your back. It's sudden and you cannot wait to call 911. In short, relax. You'll be fine, but don't wait to get in ot the doc and don't hesitate to call an ambulance if you feel chest pain/back pain. And, tell you spouse today. He/She needs to know so that they can prepare. It's super stressful, but better that they're looped in before anything happens. Peace.
