Assessing right atrial size in patients with tricuspid regurgitation: importance of the right ventricular-focused view
Authors' conclusion
In patients with STR, the use of RVF view improved the accuracy of 2DE RAV measurement as compared to the conventional 4Ch-derived measurements.
Study context
- Population
- Patients with secondary tricuspid regurgitation (STR)
- Participants
- 384 patients
- Comparison
- 2D echocardiography right atrial volume (RAV) in right ventricular focused (RVF) view vs apical 4Ch view, with 3D echocardiography as reference
- Outcome
- Accuracy of RAV measurement vs 3DE
Performance
As reported in the abstract
RAV underestimation vs 3DE
4Ch
−24%
RVF
−14%
