Background: Cerebral O saturation (ScO ) reflects cerebral perfusion and can be measured noninvasively by near-infrared spectroscopy (NIRS).
Objectives: In this pilot study, we describe the dynamics of ScO during TAVI in nonventilated patients and its impact on procedural outcome.
Methods And Results: We measured ScO of both frontal lobes continuously by NIRS in 50 consecutive analgo-sedated patients undergoing transfemoral TAVI (female 58%, mean age 80.
