RESUMO
AIM: To assess the prevalence and postprocedural evolution of cognitive impairment (CI) in patients undergoing transcatheter aortic valve implantation. METHODS: 62 patients were enrolled. Mini Mental state examination (MMSE), verbal memory test (VMT), visual search test (VST) and phonemic verbal fluency (PVF) were used to evaluate the cognitive status. CI was considered when a pathological result of MMSE was confirmed by VMT, VST and PVF. RESULTS: A total of 26.2% patients had CI at baseline. MMSE, VMT, VST and PVF were pathologic in 39, 16.1, 8.1 and 22.6% of the patients, respectively. Overall, no significant differences in cognitive function in any dimension were observed from baseline up to 1-year follow-up. CONCLUSION: CI is frequent in patients undergoing transcatheter aortic valve implantation, though the procedure does not forge cognitive status.
