I wish I could afford to come to the Mayo Clinic. My doctors are frustrating me. I have difficulty breathing on exertion and my heart goes fast. My pulmonologist says it’s not my asthma or COPD because it is too mild to cause that. My Cardiologist says it’s not my heart (even though the echo shows I have moderate/severe calcification of the aortic valve but only mild/moderate regurgitation). I have a normal thallium treadmill test. So I am frustrated. They both say it’s the other one.!! I’m at loss as to what to do.
