Karen,
Welcome to VR.com and RUN LIKE HELL from the doctor who recommended Xanax. While my aortic disease is only 2+, I have small vessel disease which causes a "coronary flow deficit" and angina-like symptoms.
It took TWO YEARS to be diagnosed and treated properly with an ACE-inhibitor and diuretic which help keep my pressures low and arteries open.
I'm in much better shape today than I was two years ago after a very, very difficult pregnancy in which my OB and then-cardio recommended Xanax which put me in the ER with pre-term contractions. (The cardio was subsequently suspended for alcoholism after showing up in the ER intoxicated while on-call).
I'm also a small woman and wonder if the chamber "standards" are a good fit. My LV is 5.4, and the RV is technically enlarged, but the word is that it could be due to the pregnancy, small vessel disease or running, not valve disease. (I was a runner for 15+ years, not during the pregnancies, of course).
Bottom line, my cardio has me taking meds which should hopefully reverse the dilation in a year, but only time will tell.
If you're feeling symptomatic, then why not press for a trial run of a low-dose vasodilator like an ACE-inhibitor? When I started taking one, the pulsations decreased.
More importantly, I would also seek another opinion from a large tertiary center like Georgetown. Cynthia M. Tracy, MD Professor of Medicine and Chief of Cardiology is an excellent cardio there. (I used to live in suburban DC).
Seven children? I am not worthy! I am not worthy! I only have three, and lots of child care help!
All the best,
