ePLAR = TRV/E/e′. Post-capillary pulmonary hypertension (PHT) is characterised by a lower ePLAR given E/e′ will be higher in these groups. Pre-capillary PHT with lower E/e′ has a higher ePLAR ratio. (A cut off value of < 0.28 m/s for post-capillary PH yielded 83% sensitivity and specificity, AUC 0.87) [12]. TRVmax tricuspid regurgitation maximum velocity, m/sec.
