Impact of Length Indexing of Deformation in Echocardiographic Evaluation of Right Ventricular Function.

ABSTRACT:

Background

When assessing right ventricular (RV) function by echocardiography, some discordance between the deformational indices is predicted on the basis of the influence of RV length. RV free wall longitudinal strain (RVFWS) is relatively independent of RV length, whereas tricuspid annular plane systolic excursion (TAPSE) reflects the strain-length product. Systolic annular velocity (s'; distance over time) is also likely to be influenced by length. The aim of this study was to test the hypothesis that indexing TAPSE and s' to RV length would lead to better congruency with RVFWS.

Methods

Two separate cohorts were identified from retrospective data: (1) subjects with normal cardiac function (n = 75) and (2) a cohort with high likelihood of potential RV dysfunction determin
