Key result
MRI-assessed TAPSE correlated well with volumetric quantification of right ventricular ejection fraction (r=0.72, p<0.001), with a multiplication factor of 2.5 providing a close estimation of RVEF.
Why the study?
Does MRI-TAPSE correlate with volumetric quantification of RVEF in patients with normal to impaired right ventricular function?

Does MRI-TAPSE correlate with volumetric quantification of RVEF in patients with normal to impaired right ventricular function?
Effect estimate: r=0.72
p-value: p=<0.001
MRI-TAPSE is a fast and easily obtainable parameter that correlates well with volumetric quantification of RVEF, and multiplying it by 2.5 provides a reliable semi-quantification of right ventricular function.

Supports quick RV assessment on MRI; extends echo correlations but leaves open outcome validation before routine use.
Speiser et al. (2012) conducted a cross-sectional in Normal to severely impaired right ventricular ejection fraction (n=76). MRI-assessed tricuspid annular plane systolic excursion (MRI-TAPSE) vs. MRI volumetric quantification of RVEF was evaluated on Correlation between MRI-TAPSE and volumetric RVEF (r=0.72, p=<0.001). MRI-assessed TAPSE correlated well with volumetric quantification of right ventricular ejection fraction (r=0.72, p<0.001), with a multiplication factor of 2.5 providing a close estimation of RVEF.
