Stroke in Transcatheter Aortic Valve Implantation (TAVI): A Comprehensive Review.

Transcatheter Aortic Valve Implantation (TAVI) has revolutionized the treatment of severe aortic stenosis in high-risk and inoperable patients. Despite significant advancements in patient selection, techniques, and the evolution of TAVI devices, stroke persists as a consistent adverse event over time, presenting a devastating complication of TAVI procedures and exerting a significant negative prognostic impact. Both acute and subsequent strokes following TAVI continue to pose significant challenges, with substantial implications for patient morbidity and mortality. This paper reviews the incidence, mechanisms, risk factors, and preventive strategies for stroke in TAVI, highlighting recent advancements, particularly in current protective devices, and ongoing challenges in minimizing this adverse outcome.
