Visual Right Ventricular Assessment in ICU: A Multicenter International Study
Authors' conclusion
Visual assessment of RV function by experienced raters shows satisfactory concordance with guideline-based FAC
Study context
- Population
- Transthoracic echocardiography recordings from critically ill patients, rated by raters from five countries73 raters
- Participants
- 115 recordings
- Comparison
- Visual grading of right ventricular (RV) systolic function, size and septal motion vs quantitative echocardiographic parameters (2025 guideline thresholds)
- Outcome
- Agreement of visual RV systolic function grading with fractional area of change (FAC)
