Right Ventricular Longitudinal Strain Reproducibility Using Vendor-Dependent and Vendor-Independent Software

•RVLS is a novel assessment of RV function. •There is little information on agreement on RVLS derived from different platforms. •We found no major systematic differences with vendor-specific imaging or algorithms. •Variability was acceptable (∼10%) for global but high (∼30%) for regional RVLS. •Global RVLS has good reproducibility for future clinical and research applications.
