Key result
Transthoracic echocardiography for mitral regurgitation quantification showed fair to moderate interobserver agreement, with senior cardiologists achieving substantial agreement for EROA (0.61).
Why the study?
Poor reproducibility in the assessment of mitral regurgitation has been reported, prompting investigation into the robustness of echocardiographic MR assessment in 2019 given technological improvements and echocardiographer skills.
What is the interobserver reproducibility of transthoracic echocardiography for assessing mitral regurgitation severity among junior and senior cardiologists?
Cross-Sectional (n=25)
Yes
What is the interobserver reproducibility of transthoracic echocardiography for assessing mitral regurgitation severity among junior and senior cardiologists?
Effect estimate: Agreement 0.61 (95% CI 0.45-0.75)
Reproducibility of echocardiographic quantification of mitral regurgitation remains challenging, with only fair overall agreement that improves slightly with reader experience.
No takes yet. Share an insight, caveat, or question.
Echocardiographic MR grading requires multiparametric caution in decisions; leaves open whether standardized training or adjunct imaging can reduce persistent interobserver variability.
Coisne et al. (2020) conducted a cross-sectional in Mitral regurgitation (n=25). Transthoracic echocardiography was evaluated on Interobserver agreement for effective regurgitant orifice area (EROA) in senior physicians (Agreement 0.61, 95% CI 0.45-0.75). Transthoracic echocardiography for mitral regurgitation quantification showed fair to moderate interobserver agreement, with senior cardiologists achieving substantial agreement for EROA (0.61).
