Does right ventricular longitudinal strain (RVLS) using speckle tracking echocardiography (STE) provide prognostic value in patients with heart failure?
Right ventricular longitudinal strain using speckle tracking echocardiography is a promising and sensitive imaging technique for evaluating RV function and prognosis in heart failure patients.
Patients with heart failure (HF) have high morbidity and mortality. Accurate assessment of right ventricular (RV) function has important prognostic significance in patients with HF. However, conventional echocardiographic parameters of RV function have limitations in RV assessments due to the complex geometry of right ventricle. In recent years, speckle tracking echocardiography (STE) has been developed as promising imaging technique to accurately evaluate RV function. RV longitudinal strain (RVLS) using STE, as a sensitive index for RV function evaluation, displays the powerfully prognostic value in patients with HF. Therefore, the aim of the present review was to summarize the utility of RVLS in patients with HF.
