Optimizing Outcomes in Transcatheter Aortic Valve Replacement Addressing Cerebrovascular Complications and Enhancing...

Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of severe aortic stenosis, becoming the gold standard for many patients. Despite its advantages over surgical aortic valve replacement, TAVR is associated with significant complications, including paravalvular leakage, conduction disorders, and cerebrovascular events. This review focuses on the pathophysiology, incidence, and management of cerebrovascular complications following TAVR. We explore the mechanisms leading to these events, including embolization of debris from the calcified valve and aortic arch, and the role of procedural factors. The review also discusses the timing of cerebrovascular events, diagnostic approaches, and potential preventive strategies, including embolic protection devices. Understanding these complications is crucial for improving patient outcomes and refining TAVR techniques.
