Will a right heart cath give my doctor information about my breathing issues?

My oxygen levels drop upon exertion.  After having many other heart related tests, doctors are recommending a right heart catheterization. Is this safe and will it give the doctors more information about breathing issues? I have previously had two left heart caths along with a heart MRI, echoes, and EKG's.

The drop in oxygen saturation is either heart or lung related. An echocardiogram should help more than a heart cath. A chest CT scan and chest x-ray may also help. Good luck!
