Fluoroscopic navigation to guide RF catheter ablation of cardiac arrhythmias

Area of Science:

• Cardiology
• Medical Imaging
• Electrophysiology

Background:

• Severe heart rhythm disorders can lead to syncope and sudden cardiac death (SCD).
• Radio-frequency (RF) catheter ablation is a primary treatment for these conditions.
• Precise localization of arrhythmogenic sites and catheter positioning are critical but challenging, often prolonging procedures.

Purpose of the Study:

• To improve the guidance of RF catheter ablation procedures.
• To enhance the efficiency and efficacy of treating severe heart rhythm disorders.
• To reduce the procedural time for RF catheter ablation.

Main Methods:

• Integration of fluoroscopic imaging data with electrical data from RF catheters.
• Development of a fused imaging approach for real-time visualization.
• Utilizing combined data to guide catheter placement and ablation targeting.

Main Results:

• The integrated imaging approach provides better visualization of arrhythmogenic sites.
• Improved catheter positioning accuracy was achieved.
• Demonstrated potential for reduced procedure duration and increased treatment success rates.

Conclusions:

• Integrating fluoroscopic and electrical data offers a promising strategy for guiding RF catheter ablation.
• This approach can lead to more efficient and effective treatment of cardiac arrhythmias.
• Enhanced visualization aids in overcoming current localization and positioning challenges in ablation procedures.
