PROCESSED EEG AND NON-INVASIVE CEREBRAL OXIMETRY (Cerebral rSO2) MONITORING IN TRANSCATHETER AORTIC VALVE IMPLANTATION (TAVI)
Raquel Caetano, Ana Veiga de Sá, Joana Moreira, Manuel Campos.
Background: 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.
Case description: 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.
Conclusions: 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.
