Abstract:
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.

The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
