Is there intervendor consistency and reproducibility of left ventricular 2D global and regional strain with two different high-end ultrasound systems?
Despite improvements following standardization initiatives, significant wide limits of agreement persist between vendors, particularly for regional strain, necessitating consistent vendor software for serial measurements.
Intervendor agreement in GLS and regional strain measurements have significantly improved after the EACVI/ASE Task Force Strain Standardization Initiatives. However, significant wide LOA still exist, especially for regional strain measurements, which remains relevant when considering vendor-specific software for serial measurements.
Shiino et al. (Mon,) studied this question.
