Noninvasive Estimation of Pulmonary Vascular Resistance Using Right Ventricular Outflow Doppler Analysis

Noninvasive Estimation of Pulmonary Vascular Resistance Using Right Ventricular Outflow Doppler Analysis

Background: Right heart catheterization (RHC) is the gold standard for measuring pulmonary vascular resistance (PVR). Current noninvasive methods lack accuracy, especially in moderate to severe pulmonary arterial hypertension. Objectives: The objective of the study was to develop and validate a nove...
