Can an echocardiogram show PH when a right heart catheterization doesn't?
This situation can happen because echocardiograms and right heart catheterizations measure pulmonary hypertension differently.
Echocardiograms are screening tests that estimate pulmonary artery pressure from outside the body. They can suggest PH, but they're not as precise as right heart catheterization.
Right heart catheterization is the gold standard for diagnosing PH because it directly measures the actual pressure inside your pulmonary arteries. If the catheterization didn't show PH, it means your direct pressure measurements were below the diagnostic threshold (typically 20 mm Hg or higher).
Sometimes echocardiograms can overestimate pressures or show indirect signs that suggest PH when it's not actually present. This is why doctors use right heart catheterization to confirm the diagnosis.
Regarding VA disability ratings, the VA typically relies on confirmed diagnoses using the most accurate testing available. Since right heart catheterization is considered the definitive test, they would likely give more weight to those results. However, VA decisions can be complex and depend on your complete medical record, symptoms, and how your condition affects your daily functioning.
You may want to discuss these conflicting results with your cardiologist or pulmonologist to understand what they mean for your specific situation and whether any follow-up testing is needed.
