Figure 6.

Association of the RV systolic pressure differential obtained during routine RHC with a non-invasive surrogate of RV-pulmonary arterial coupling (TAPSE/PASP) in a retrospective pulmonary arterial hypertension cohort from the Giessen Pulmonary Hypertension Registry (n = 113; Spearman correlation). BSP, beginning-systolic pressure; ESP, end-systolic pressure; PASP, pulmonary arterial systolic pressure; RHC, right heart catheterization; RV, right ventricular; TAPSE, tricuspid annular plane systolic excursion.
