Thanks so much for your reply! My Cardiologist didn't say anything about right heart enlargement, but a couple years ago I had an EKG that supposedly showed Biatrial Enlargement. Nothing was ever said about that.
I didn't hear anything about pulmonary stenosis either. He referred me to a Pulmonogist for testing but didn't say much beyond that.
Echos are not always ideal for measuring the pulmonary pressure. It is, in fact, an estimate based off of tricuspid insufficiency. Upwards of 60% of normal people have some degree of tricuspid insufficiency which would equate to a higher pressure estimate of the pulmonary artery.
The diagnosis of pulmonary hypertension is more of a disease of elimination. They need to find underlying causes, if any, before that diagnosis can be made. Furthermore, are they seeing any rt heart enlargement? Any pulmonary stenosis?
The gold standard is right heart cath since it is a direct measurement.
