In a selected subgroup of patients with baseline echo-derived PVR > 5.45 Wood Units, deterioration in echo-derived PASP at follow-up predicts deterioration in repeat RHC-derived with 73% sensitivity, 91% specificity, 73% positive predictive value and 91% negative predictive value. (PASP: Pulmonary Artery Systolic Pressure, RHC: Right Heart Catheterization).

		RHC-Derived PASP
		Deteriorated ≥ 10%	Stable or Improved ≥ 10%	Total
Echo-derived PASP	Deteriorated ≥ 10%	11	4	15
	stable or improved ≥ 10%	4	39	43
	total	15	43	58
