Key result
RV fractional area change (RVFAC) correlated best with MRI-derived right ventricular ejection fraction (RVEF) with r = 0.80, P < 0.001.
Why the study?
Which commonly used 2D echocardiographic measure of right ventricular function correlates best with MRI-derived right ventricular ejection fraction?

Right ventricular fractional area change (RVFAC) is the most accurate 2D echocardiographic parameter for estimating right ventricular ejection fraction when compared to cardiac MRI.
No takes yet. Share an insight, caveat, or question.
RVFAC may best approximate RVEF on 2D echo; leaves open prospective validation in larger cohorts.
Anavekar et al. (2007) studied this question. RV fractional area change (RVFAC) correlated best with MRI-derived right ventricular ejection fraction (RVEF) with r = 0.80, P < 0.001.
