[Advances in stroke after transcatheter aortic valve replacement]

Area of Science:

• Cardiology
• Neurology
• Interventional Cardiology

Background:

• Transcatheter aortic valve replacement (TAVR) is increasingly common.
• TAVR-related stroke is a significant concern, affecting patient prognosis and quality of life.
• Inconsistent diagnostic criteria lead to varied reported incidence rates of TAVR-related stroke.

Purpose of the Study:

• To review current research on TAVR-related stroke.
• To focus on epidemiology, risk factors, and preventive measures.
• To provide clinical guidance for managing stroke in TAVR patients.

Main Methods:

• Literature review of TAVR-related stroke.
• Analysis of stroke classification by onset time (acute, subacute, early, late).
• Identification of surgical and non-surgical risk factors.

Main Results:

• TAVR-related stroke incidence varies due to diagnostic inconsistencies.
• Stroke causes differ based on onset time.
• Surgical factors (e.g., valve type, access) and non-surgical factors (e.g., calcium burden, atrial fibrillation) contribute to stroke risk.

Conclusions:

• Effective prevention strategies include postprocedural monitoring, antithrombotic therapy, and embolic protection devices.
• Understanding risk factors is crucial for mitigating TAVR-associated cerebrovascular events.
• This review offers insights for optimizing clinical management and improving patient outcomes after TAVR.
