Thoracic Aorta Measurements Using Intraoperative Transesophageal Echocardiography: Validation via Cardiac Magnetic Resonance
Authors' conclusion
This study demonstrates the feasibility of intraoperative TEE to accurately measure aortic diameters in patients with ascending aortic aneurysms.
Study context
- Population
- Patients with ascending aortic aneurysm undergoing ascending aortic repair with a prosthetic (Dacron) graft, without severe aortic valve disease
- Participants
- 30 patients
- Exposure
- Intraoperative 2D and 3D transesophageal echocardiography (TEE) vs preoperative CMR for aortic diameter measurement
- Outcome
- Association and agreement between TEE and CMR aortic diameter measurements

Main finding
As reported in the abstract
Correlation and agreement of TEE with CMR
- Correlation TEE vs CMR, root
- r = 0.94-0.97; p < 0.001 for all
- Correlation TEE vs CMR, ascending
- r = 0.95-0.98; p < 0.001 for all
- Correlation TEE vs CMR, arch
- r = 0.88; p < 0.001
- Correlation TEE vs CMR, descending
- r = 0.91; p < 0.001
- Bland-Altman mean differences, 2D TEE vs CMR (range)
- 0.05-0.22 cm
- Bland-Altman mean differences, 3D TEE vs CMR (range)
- 0.04-0.18 cm
