Effect of New Cerebral Ischemic Lesions on the Delirium Occurrence After Transcatheter Aortic Valve Replacement

Although only 2% to 5% of patients develop symptomatic stroke following transcatheter aortic valve replacement (TAVR), new cerebral lesions have been detected among the majority of these patients using diffusion weighted magnetic resonance imaging (DWI-MRI), irrespective of access site strategy(1). According to the published reports, new cerebral DWI lesions have been associated with future neurological and cognitive decline; however, the relationship between these lesions and post-operative delirium (POD) following TAVR remains unknown. By means of this study, we aimed to assess the impact of new cerebral DWI lesions on the occurrence of POD following TAVR.
