Comparison of features of different echocardiographic modalities

	TAPSE	S′	RVFAC	RV strain	3D RV volumetry
Angulation	Angle dependent 87 , 88 , 89	Angle dependent 87 , 89	Independent of angulation	Independent of angulation 73 , 88 , 89 , 90	Independent of angulation
Application	Simple and reproducible 89	Simple and reproducible	Complex; correct tracking of RV endocardial border required	Complex; correct endocardial tracking required 88 , 89	Complex; precise imaging with adequate frame rate required
RV regions covered	Basal free wall and lateral tricuspid valve insertion 40	Basal free wall 87	Entire RV section in apical 4‐chamber view	Global and regional analysis of 6 segments 40	All RV regions; accounts for complex RV anatomy
Shortening axis	Longitudinal 64 , 75	Longitudinal 64 , 75	Longitudinal and radial 64 , 73 , 75	Longitudinal 64	Longitudinal, radial, and anteroposterior

3D, three‐dimensional; RV, right ventricular; RVFAC, right ventricular fractional area change; TAPSE, tricuspid annular plane systolic excursion.
