Right Ventricular Global Longitudinal Strain Is an Independent Predictor of Right Ventricular Function: A Multimodality Study of Cardiac Magnetic Resonance Imaging, Real Time Three-Dimensional Echocardiography and Speckle Tracking Echocardiography

Objectives Accurate assessment of right ventricular (RV) systolic function is important, as it is an established predictor of mortality in cardiac and respiratory diseases. We aimed to compare speckle tracking–derived longitudinal deformation measurements with traditional two‐dimensional (2D) echoca...

Description
Summary:Objectives Accurate assessment of right ventricular (RV) systolic function is important, as it is an established predictor of mortality in cardiac and respiratory diseases. We aimed to compare speckle tracking–derived longitudinal deformation measurements with traditional two‐dimensional (2D) echocardiographic parameters, as well as real time three‐dimensional echocardiography (RT3DE) and cardiac magnetic resonance imaging (CMR)‐derived RV volumes and ejection fraction (EF). Method Subjects referred for CMR also underwent echocardiography. On both RT3DE and CMR, we measured RV volumes and EF. On 2D echocardiography, we analyzed RV fractional area change, RV internal diastolic diameter, tricuspid annular plane systolic excursion, tricuspid annular tissue Doppler–derived velocity, myocardial performance index, and RV global longitudinal strain (RV GLS). Results Sixty subjects were recruited (mean age = 45 ± 10 years; 60% male). RV GLS (R = −0.69, P
