Epicardial Ablation via Arterial and Venous Systems

Area of Science:

• Cardiology
• Electrophysiology
• Vascular Interventions

Background:

• Ventricular and atrial arrhythmias pose significant clinical challenges.
• Current mapping and intervention strategies have limitations in accessing certain cardiac regions.
• Epicardial surface vessels offer unique anatomical access points.

Purpose of the Study:

• To describe the utility of intracoronary artery and venous routes for cardiac arrhythmia mapping and interventions.
• To highlight the advantages of these routes for accessing intramural cardiac regions.
• To present the tools and techniques employed for intracoronary interventions.

Main Methods:

• Utilizing intracoronary artery and venous routes for anatomical mapping.
• Employing multipolar catheters and wires for local electrogram recording in smaller vessels.
• Performing site-specific mapping and interventions within intramural regions.
• Considering adjunctive endocardial/epicardial ablation when necessary.

Main Results:

• Intracoronary routes provide direct access to epicardial surfaces, bypassing the pericardial space.
• These routes enable interventions in intramural areas not reachable by endocardial or epicardial approaches.
• Multipolar tools facilitate detailed electrogram mapping within small vessels.
• Successful outcomes can be enhanced by combining intracoronary techniques with ablation.

Conclusions:

• Intracoronary artery and venous routes represent a valuable strategy for complex arrhythmia management.
• These approaches expand the возможности for targeted interventions in challenging cardiac anatomies.
• The described tools and techniques enhance the precision and efficacy of intracoronary procedures.
