I get an echo every 6 months since being diagnosed with an ascending aneurysm almost 11 years ago at Mayo Clinic in Jacksonville, FL. I have all records of my previous echoes dated all the way back to 2005 at Mayo and they always measured my R. side heart at normal size. I live in another state in a small town and I had a Ct scan here in 2009 and 2012 and they also showed my R. side heart as normal in size. I have a few benign lung scars from possibly past infections or pleurisy...Never did smoke. Now the echo I had a few weeks ago says my R. side heart is in the upper limits of normal...I asked my doc if having the scar tissue would make my right side heart work harder and make it larger? She said, yes....but the scar tissue has remained the same since it was discovered back in 2005. Located on top of both lungs and not very large....also have a 5 mm benign nodule on one lung as well..has not changed either. So that is my history. Now I AM WORRIED as to what is going on...or maybe did the echo just mis-measure slightly and everything is really normal???? Very scared here....I also have cats and have for years taken care of their litter boxes and have breathed in cat litter dust I would imagine from time to time....I can take clear long breaths.....with no pain...no coughing, etc. Hard to get back in with my Cardio doc to show her my past medical records, scan results and echo results. I would have to wait another 4 months...Small town and lack of doctors...make it hard to get in...Wondering if I should see a Pulmonary doc??? Or, should I wait for my next echo in 6 months like the Cardio doc said to do when I left her office. After all my research, now I know what I should have asked her, but, cannot get in to see her...WHAT DO I DO IN THE MEANTIME? Thank you....
