i had a CT scan and was told I had an enlarged heart. I then had an Echo Cardiagram and showed normal sized heart, both venticals normal, but a small leak in Pulmonary valve. Also measures your Pulmonry artery pressure, it was higher than normal, but mildly so. Second one, 3 yrs later, said moderate!
I went to NJH because I didn't like that it was not being checked each year. Also have MAC, and Bronchiestasis. I had an Echo Cardiagram while in Denver, but I went to Rose Medical. They specialize in Cardiac problems. I needed to go there straight from airport for another problem, so they did it there. My numbers, although lower than the one I had at home, still indicate mild PH, not moderate
The gold standard, they say, is to have a Cardiac Cath.. But the Cardiologist, and Pulmonologist in Denver thought mild, with no heart involement, was very good. I trust them much more than my old Pulmonologist that asked me; "who told you that you had Pulmonary Hypertention!" Thats when I made appoiuntment with NJH. I trust NJH. They helped me before, when doctors here didn't. Once a patient there, always a patient.
I know they do Echos at NJH, but I was just in Rose Medical so they called NJH and did some of my testing there.
I have no symptoms, and my right side of heart is normal. I hope I have helped you some.

I had a similar call from a Radiologist after a CT and had an Echocardiogram last spring.
Then 6 months later, NJH ordered a Echocardiogram with bubbles. The bubbles test for a hole between heart chambers. Both tests were negative.
