Does a right atrium dilated, rv pressure of 25-30 mhg, ivc dynamics 5-10 mmhg subjective possibly of pulmonary hypertension or heart failure?

If accurate, only: mildly ↑ed. RA ~5 mmHg, RV systolic ~25 mmg Hg generally ~optimally healthy; similar to the values stated. Thus RA enlargement likely: mismeasurement (common, not rare; study image data yourself), marked tricuspid regurgitation, congenital variant, atrial muscle problem [eg advanced arterial disease in RA arteries; (lumens too small to see by angiography) producing RA ischemia/fibrosis], etc.
