Assessment of Right Ventricular Longitudinal Strain in Patients with Ischemic Cardiomyopathy: Head-to-Head Comparison between Two-Dimensional Speckle-Based Strain and Velocity Vector Imaging Using Volumetric Assessment by Cardiac Magnetic Resonance...
Background Longitudinal strain of right ventricle ( RV) can be used to determine RV systolic function. This study compared RV longitudinal strain values of two different speckle tracking software technologies, velocity vector imaging ( VVI) and two-dimensional speckle tracking echocardiography (2 DS...

This study compared RV longitudinal strain values of two different speckle tracking software technologies, velocity vector imaging ( VVI) and two-dimensional speckle tracking echocardiography (2 DSTE), and longitudinal strain by cardiac magnetic resonance ( CMR). Methods We studied 36 patients (28 men, 63 ± 11 years) with ischemic cardiomyopathy ( ICM) who underwent echocardiography with GE machines and CMR. Longitudinal strain of RV analyzed with 2 DSTE and VVI in same DICOM files. Longitudinal RV strain analyzed with 2 DSTE and VVI in same raw data. These values were compared with RVEF and longitudinal strain by CMR. Results VVI strain showed significant correlations with RVEF by CMR (global RV: r = −0.56, P < 0.01, free wall: r = −0.52, P < 0.01, and septum: r = −0.49, P < 0.01). 2 DSTE strain also revealed significant correlations (global RV: r = −0.40, P = 0.02, and septum: r = −0.35, P = 0.04). 2 DSTE strain had significant bias with wide limits of agreement in global RV and septum compared with CMR strain. 2 DSTE strain had significantly lower intra-observer variability than VVI (P = 0.03) or CMR strain (P = 0.04) in RV-free wall. Conclusions RV longitudinal strains by VVI and 2 SDTE demonstrated relatively good correlations with RVEF and longitudinal strain by CMR. However, when compared to CMR-derived strain, 2 DSTE-derived strain underestimates longitudinal strain of RV septum and of global right ventricle. 2 DSTE strain had significantly lower intra-observer variability compared with VVI or CMR strain analysis. pubtype: Academic Journal doctype: diagnostic images research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
