Three-Dimensional Echocardiographic Approach to Mitral Valve After Transcatheter Edge-to-Edge Repair
Authors' conclusion
In this retrospective cohort study, we demonstrated excellent agreement between TEE-3DOA-derived MVA under GA and TTE PHT-derived MVA in awake patients, but not between TEE versus TTE PHT.
Study context
- Population
- Adults with severe mitral regurgitation undergoing transcatheter edge-to-edge repair (TEER) (MitraClip, Abbott)
- Participants
- 20 adults
- Exposure
- Transesophageal echocardiography (TEE) 3DOA and TEE pressure half-time (PHT) under general anesthesia (GA) vs TTE PHT in awake patients for post-TEER MVA
- Outcome
- Agreement of MVA measurements (Bland-Altman 95% limits of agreement and Lin's concordance correlation coefficient)
Methodological detailsmethod-agreement study
- Method-agreement study
Main finding
As reported in the abstract
Agreement of post-TEER MVA measurements with TTE PHT
- TEE 3DOA · excellent
- concordance correlation coefficient 0.95 (95% CI 0.86–0.98)
- TEE 3DOA
- Bland-Altman upper limit of agreement 0.26 (95% CI 0.12–0.4)
- TEE PHT · weak
- concordance correlation coefficient 0.46 (95% CI 0.02–0.75)
- TEE PHT · much broader limits of agreement
- Bland-Altman lower limit of agreement −1.6 (95% CI −2.19 to −1.02)
- TEE PHT
- Bland-Altman upper limit of agreement 1.43 (95% CI 0.84–2.01)
Observational data: associations, not effects.
