The Use of Contrast May Improve Aortic Valve Assessment During Transesophageal Echocardiography
Authors' conclusion
This discrepancy is significant and could affect the decision to replace the aortic valve.
Study context
- Population
- Patients undergoing surgical aortic valve replacement for a stenotic valve, tertiary hospital
- Participants
- 30 consecutive patients
- Exposure
- Contrast vs noncontrast transesophageal echocardiography (TEE) Doppler assessment of the aortic valve
- Outcome
- Aortic valve area
Methodological detailssingle-centre, retrospective review, consecutive patients, Bland-Altman analysis
- Single-centre
- Retrospective review
- Consecutive patients
- Bland-Altman analysis
Main finding
As reported in the abstract
Without contrast agent, aortic valve area overestimated vs TTE
0.26 cm²
Observational data: associations, not effects.
Further findings
Peak and mean aortic valve gradients without contrast
- Peak gradient underestimated (mmHg)
- 19
- Mean gradient underestimated (mmHg)
- 11
- p value <0.001
Pulse-wave Doppler V1 velocity of the left ventricular outflow tract (LVOT)
- Not affected by contrast
