Misidentification of the True Aortic Annulus With 2-dimensional Echocardiography: A Critical Appraisal Using 3-Dimensional Imaging
Authors' conclusion
The study highlighted the limitations of 2D echocardiography in accurately identifying the true AV annulus in complex 3D structures like the aortic root.
Study context
- Population
- National Board of Echocardiography (NBE)-certified perioperative echocardiographers across 12 academic institutions; images from 11 patients with normal aortic valve (AV) and aortic root anatomies undergoing CABG
- Participants
- 45 qualified survey respondents
- Outcome
- Accuracy of identifying the true AV annulus using 2D echocardiography
