During a routine chest x-ray and confirmed through a echo-cardio gram, I have been told I have a thoracic aortic aneurysm. My doctor has indicated that it's no big deal at this time and we will watch my blood pressure and have a cat scan every 6 mths. I asked him about my diving and he said he would consult the thoracic surgeon who looked at my echo. I've not been told to limit my excersizing. How do I find out more about any diving considerations?
