Cerebral Protection Devices during Transcatheter Interventions: Indications, Benefits, and Limitations

Area of Science:

• Cardiovascular Interventions
• Neurology
• Medical Device Technology

Background:

• Stroke is a significant complication following various cardiovascular interventions.
• Cerebral protection devices (CPDs) are designed to mitigate stroke risk during these procedures.

Purpose of the Study:

• To review stroke rates and outcomes in different cardiovascular procedures.
• To evaluate the current evidence for the use of cerebral protection devices (CPDs).

Main Methods:

• Review of existing literature and clinical trial data.
• Analysis of stroke incidence and outcomes across diverse cardiovascular interventions.
• Assessment of the feasibility, safety, and potential impact of CPDs.

Main Results:

• Stroke rates vary significantly by procedure: up to 9.1% post-TAVI, 3.9% post-mitral clipping, 3.1% post-LAAO, 0.4% post-PCI, and 1.8% post-ablation.
• CPDs are technically feasible and safe but lack randomized controlled trial (RCT) data demonstrating clinical impact and stroke reduction.
• Current evidence primarily supports CPD use in high-risk TAVI patients, with the PROTECTED TAVI RCT pending.

Conclusions:

• Routine use of CPDs is not supported in procedures like mitral clipping, PCIs, and ablation based on current data.
• CPDs show potential, especially in TAVI, but further RCT evidence is crucial to confirm their efficacy in stroke reduction.
