Introduction
Results
Right ventricular function (RVF) is a key prognostic factor in pulmonary arterial hypertension (PAH). While cardiac MRI is the gold standard for assessment of RVF, quantitative measurement is effort-intensive. Measurement of tricuspid annular plane systolic excursion (TAPSE) using echo is a simplified measure of RVF that correlates well with invasive hemodynamics, RVF, and predicts outcomes in PAH.
TAPSE TV was moderately well correlated with echo (r = 0.46, p = 0.02) and RVEF (r = 0.54, p < 0.01). TAPSE Cor was similarly correlated with RVEF (r = 0.49, p = 0.01) and nonsignificantly correlated with Echo TAPSE (r = 0.38, p = 0.06).
Purpose We tested the hypothesis that MR measured TAPSE correlates with echo measured TAPSE and with invasively measured hemodynamics.
All methods performed well to detect moderately depressed (
