Predictive Value of the Venous Excess Ultrasound Score for Acute Kidney Injury After Transcatheter Aortic Valve Replacement: A Retrospective Cohort Study
Authors' conclusion
Venous congestion appears to contribute to AKI in patients undergoing TAVR.
Study context
- Population
- Patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR) at two cardiovascular centres
- Participants
- 101 patients
- Exposure
- Preprocedural vs postprocedural Venous Excess Ultrasound Score (VExUS) for prediction of acute kidney injury (AKI) after TAVR
- Outcome
- AKI (KDIGO criteria) within 7 days after TAVR or before hospital discharge
- Follow-up
- Within 7 days
Methodological detailsregister study, two centres

Main finding
As reported in the abstract
Discrimination of VExUS for AKI
| Group | AUC |
|---|---|
| Preprocedural VExUS | 0.62 (95% CI, 0.49-0.75) |
| Postprocedural VExUS | 0.97 (95% CI, 0.95-1.00) |
AUC
Preprocedural VExUS0.62 (95% CI, 0.49-0.75)
Postprocedural VExUS0.97 (95% CI, 0.95-1.00)
- AKI after TAVR (whole cohort)
- 18%
- VExUS grade ≥2: sensitivity for AKI
- 100%
- VExUS grade ≥2: specificity for AKI
- 88%
- Association of VExUS grade ≥2 with AKI, p
- P < 0.0001
Observational data: associations, not effects.
