Data are presented as mean ± standard deviation with r- and P-values reflecting correlation of TTE values with CMR-RVEF. Values in bold indicate a P-value <0.05. RV wall average LS calculated when lateral, anterior, and inferior walls all feasible to measure.

RV, right ventricle; TAPSE, tricuspid annular plane systolic excursion; RV S′, tissue Doppler imaging derived tricuspid annular peak systolic velocity.

*P < 0.01 vs. RV lateral wall LS.
