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

ABSTRACT: BACKGROUND:Right ventricular peak systolic longitudinal strain (RVLS) has emerged as an approach for quantifying right ventricular function in diseases such as pulmonary hypertension and congenital heart disease. A major limitation in applying RVLS is that strain imaging and analysis are proprietary, which may result in systematic differences from vendor to vendor. The goal of this study was to test the reproducibility of right ventricular strain analysis among selected vendor-specific software (VSS) and vendor-independent software (VIS) on images obtained from different ultrasound scanners, as would be common in clinical practice or in a multicenter clinical trial. METHODS:In this prospective, single-center study, 35 patients (5 healthy subjects and 30 with pulmonary hypertension) each un
