Cerebrovascular accidents (CVA), mainly stroke, are still one of the Achilles’ Heels of transcatheter aortic valve implantation (TAVI) procedures; however, clinically evident strokes are not the only concern. TAVI procedures have also been associated with covert cerebral emboli captured on transcranial Doppler as high-intensity transient signals (HITS) and ultimately defined as silent brain infarcts, as documented on diffusion-weighted imaging magnetic resonance imaging (DWI-MRI)1,2. Notably, the incidence of silent brain infarcts is very much higher (up to 90%)1 than that of clinically evident strokes, which ranges from 0%3 to 2.3-2.5% at 30 days4.
