We are headed to S. America. Not sure about insurance, but anywhere in the world is probably less expensive than the US, where I live. I'd have to work that out after the fact, but I did see a cardiologist yesterday and he was very unconcerned about my aorta. He said it isn't an aneurysm yet, just a dilation that should be monitored. He looked at my EKG and history (I have no other cardiac issues, zero calcium, non-smoker, exercise daily, low cholesterol, and low/normal BP with a small amount of medication). He said to go enjoy my trip, the chance of rupture is very low and to keep exercising as usual, even higher intensity cardio, just no heavy lifting that requires strain or breath holding. I feel much better about everything now.
