Key result
Stroke after TAVR occurs in three distinct phases (early procedure-related, day 2-30, and late hazard), each driven by different etiologies requiring specific management strategies.

This review outlines the distinct phases and etiologies of stroke following TAVR to guide appropriate management strategies.
Transcatheter aortic valve replacement (TAVR) has become the default treatment option for high-risk patients with aortic stenosis and an alternative to surgical aortic valve replacement in intermediate-risk patients. There are, however, concerns regarding strokes during TAVR. Reported stroke rates vary strongly depending on the type of study, stroke definition, cohort and study period. Furthermore, stroke after TAVR occurs in three distinct phases: 1) early high-risk, directly procedure related; 2) elevated risk interval between day 2 and day 30; 3) late hazard interval. Each of these phases is caused by the different aetiologies of stroke. This review summarises the different aetiologies and potential strategies for managing stroke during TAVR.

Hecker et al. (2017) conducted a review in Aortic stenosis. Transcatheter aortic valve replacement (TAVR) was evaluated. Stroke after TAVR occurs in three distinct phases (early procedure-related, day 2-30, and late hazard), each driven by different etiologies requiring specific management strategies.
