Despite current valve guidelines recommending both transcatheter and surgical aortic valve replacement (TAVR and SAVR, respectively) in patients with symptomatic severe aortic stenosis (AS), TAVR has recently become the preferred treatment over SAVR, driven by its minimal invasiveness, faster recovery and earlier improvement in quality of life. However, several limitations and unresolved issues remain with TAVR, including stroke, conduction system disorder, durability, bicuspid anatomy, coronary reaccess and lifetime management with aortic valve reintervention. Our review aims to highlight the above issues and discuss them in depth, to demonstrate the complementary role of TAVR and SAVR in the treatment of AS., (Copyright © 2022 Elsevier Inc.

In the past two decades, transcatheter aortic valve replacement (TAVR) has transformed the management of aortic stenosis and has become the standard of care regardless of surgical risk levels. Advances in transcatheter valve design across newer generations, improved imaging, greater operator expertise, and technical enhancements have collectively contributed to increased safety and a decline in procedural complications over this timeframe. The application of TAVR has progressively expanded to include younger patients with lower risks, who have longer life expectancies. This article offers an up-to-date review of the latest innovations in transcatheter delivery systems, devices, and its possible future indications. [ABSTRACT FROM AUTHOR]

Transcatheter aortic valve replacement (TAVR) has become the treatment option for symptomatic severe aortic stenosis patients across all risk profiles. Despite remarkable advancements in technology and operator experience, the occurrence of periprocedural stroke remains a significant concern, predominantly attributed to thromboembolic events in the immediate postprocedural period. To optimize patient outcomes, various strategies have been developed to minimize the risk of stroke, encompassing comprehensive preprocedural planning, effective management of comorbidities, utilization of cerebral embolic protection devices, and tailored medical therapy. This comprehensive review summarizes the currently available strategies for mitigating periprocedural stroke post‑TAVR and provides insights into future directions. [ABSTRACT FROM AUTHOR]
