Pulmonary Vein Isolation Using a Circular Multielectrode Pulsed Field Ablation Catheter via a Jugular Vein Approach

Area of Science:

• Cardiology
• Electrophysiology
• Medical Devices

Background:

• Catheter ablation is a common treatment for atrial fibrillation.
• Pulmonary vein isolation (PVI) is a key strategy in catheter ablation.
• Superior approaches for PVI can present technical challenges.

Purpose of the Study:

• To evaluate the feasibility of using a circular multielectrode pulsed field ablation (PFA) catheter for PVI.
• To assess the efficacy of a superior jugular vein approach for PVI in atrial fibrillation.

Main Methods:

• Utilized a circular multielectrode PFA catheter.
• Performed PVI via a superior jugular vein approach.
• Assessed technical feasibility and procedural outcomes.

Main Results:

• The circular multielectrode PFA catheter demonstrated feasibility for PVI.
• The superior jugular vein approach was found to be a viable route for PVI.
• This technique offers a potential solution for challenging PVI cases.

Conclusions:

• Catheter-based PVI using PFA via a superior jugular vein approach is technically feasible.
• This approach may overcome challenges associated with superior access for PVI.
• PFA offers a promising alternative for atrial fibrillation ablation.
