Abstract:
With the clinical generalization and popularization of transcatheter aortic valve replacement (TAVR), cerebrovascular events related to TAVR occur more frequently, which significantly impairs neurocognitive function, increases mortality, and seriously affects prognosis and quality of life in these patients. However, the reported incidence rates of TAVR-related stroke differ in literature due to inconsistent diagnostic criteria. According to the onset time, TAVR-related stroke can be divided into acute (≤24 h), subacute (24 h-30 d), early (31 d-1 year) and late (>1 year) types, and the cause of stroke generally varies according to the onset time. Both surgical (balloon aortic valvuloplasty, types of transcatheter heart valve, alternative access) and non-surgical (valvular calcium burden, bicuspid aortic valve, subclinical leaflet thrombosis, postoperative new-onset atrial fibrillation) can be related to the occurrence of TAVR-related stroke. Postprocedural monitoring, postprocedural antithrombotic therapy, and cerebral embolic protection devices are important for the prevention of TAVR-related stoke. This article reviews the research progress on TAVR-related stroke, focusing on its epidemiology, risk factors and preventive measures, aiming to provide reference for the clinical management of stroke in TAVR.
