Cerebral regional oxygen saturation as a predictive parameter for preoperative heart failure and delayed hemodynamic recovery in transcutaneous aortic valve implantation: a retrospective cohort study
Authors' conclusion
Baseline cerebral rSO2 is associated with preoperative variables related to cardiac failure and function, and a significant decline during valve deployment may indicate a risk of prolonged hypotension during TAVI.
Study context
- Population
- Patients undergoing transfemoral transcatheter aortic valve implantation (TAVI) under GA with left-hemisphere cerebral rSO2 monitoring (near-infrared spectroscopy) at five time points60 balloon-, 31 self-expandable valves
- Participants
- 91 patients
- Exposure
- Cerebral rSO2 by speed of SBP recovery after valve deployment and valve type
- Group Cn = 31
Main finding
As reported in the abstract
- Baseline cerebral rSO2 correlated with B-type natriuretic peptide, hemoglobin, fractional shortening, ejection fraction, left ventricular mass index, left ventricular end-systolic diameter, STS risk of mortality, and STS morbidity or mortality
- Group B had lower cerebral rSO2 during valve deployment vs groups A and C
Observational data: associations, not effects.
