2024 Update on Cerebral Embolic Protection After Transcatheter Aortic Valve Replacement

Abstract

Cerebral embolic protection (CEP) during transcatheter aortic valve replacement (TAVR) has emerged as an important tool in reducing stroke risk associated with this intervention. With the recent expansion of TAVR into lower-risk populations, the role of preventive strategies gained greater significance. Despite advancements in TAVR technologies, peri-procedural stroke remains a significant complication, with rates ranging between 2 and 5%. CEP devices, introduced at the time of the procedure, have been developed to capture embolic debris and reduce the risk of neurological events. However, while MRI-detected embolic debris is commonly captured by these devices, the clinical benefit in reducing stroke remains debated. This review provides a comprehensive analysis of recent advances in relevant clinical research and CEP device development, offering recommendations for future studies to improve patient outcomes.
