I have a enlarged right ventricle with no known cause. I just had an echo and a stress test and ct of the heart and doppler of my legs.

I was now requested to take the tee exam is this really going to be beneficial. I know on the echo is where they found my enlargement. The ct scan showed a hoe on the top of my heart with a small shadow they could not identify.

I experienced some chest pressure then I could not breath to the point where I thought I was going to pass out. I've had some smaller episodes in the er.

Can anyone give me some sound advice...

Take the test. Confirm the diagnosis and work on a treatment plan with doctor. That is the best course of action that will have the best outcome. Relying on the advice of internet people can be a little dodgy.
