RV strain and Tei index merit testing in larger animal PH models; leaves open human validation and clinical adoption.
Do echocardiographic indices of RV function correlate with right heart catheterization variables in dog models of mild RV pressure overload?
Free wall RVLS, RV-SD, and Tei index are useful echocardiographic parameters for assessing hemodynamic changes under mild RV pressure overload conditions.
Morita et al. (2017) studied this question.
