Why the study?
Is there intervendor consistency and reproducibility of left ventricular 2D global and regional strain with two different high-end ultrasound systems?
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.
No takes yet. Share an insight, caveat, or question.
Supports consistent vendor use for serial GLS monitoring; leaves open whether further standardization narrows regional strain LOA.
Shiino et al. (2016) studied this question.
