【 摘 要 】

Transcatheter aortic-valve implantation (TAVI) has been suggested as a less invasive treatment for high-risk patients with aortic stenosis. Ischemic events remain a troublesome risk following TAVI. The use of neuromonitoring with cerebral rSO2 and Processed EEG may contribute to detect and correct imbalances in the oxygen demand-to-delivery ratio. We describe two clinical cases of TAVI procedure-related complications with cerebrovascular repercussions that reflected on cerebral oximetry and electrical activity as detected by NIRS and processed EEG. Cerebral rSO2 and processed raw EEG monitoring is relevant and useful in this setting, enabling clinicians to identify and possibly take preventive/corrective actions on the peri-operative setting, in order to minimize secondary damage due to ischemic/hypoxic events.
