Circumferential strain may offer greater dyssynchrony sensitivity; leaves open whether it improves CRT selection or outcomes.
Does circumferential strain analysis provide better sensitivity to cardiac dyssynchrony compared to longitudinal strain?
Circumferential deformation may offer a more sensitive noninvasive measure of cardiac dyssynchrony compared to longitudinal strain.
Helm et al. (2005) studied this question.
