The first Latin American Catheter Ablation Registry

Area of Science:

• Cardiology
• Electrophysiology
• Medical Informatics

Background:

• Cardiac arrhythmias represent a significant global health burden.
• Transcatheter ablation has emerged as a primary treatment modality for various arrhythmias.
• Limited data exists on the outcomes of transcatheter ablation in Latin America.

Purpose of the Study:

• To evaluate the efficacy and safety of transcatheter ablation procedures for cardiac arrhythmias in Latin America.
• To establish the inaugural Latin American transcatheter ablation registry.

Main Methods:

• Retrospective analysis of 15,099 transcatheter ablation procedures performed in 2012.
• Data collected from 120 centers across 13 Latin American countries.
• Included analysis of center characteristics and ablation outcomes for 17 arrhythmia types.

Main Results:

• Accessory pathway ablation was most common (31%), followed by atrio-ventricular node reentrant tachycardia (29%).
• Overall procedural success rate was 92%.
• The global complication rate was 4%, with a mortality rate of 0.05%.

Conclusions:

• Transcatheter ablation for cardiac arrhythmias in Latin America demonstrates favorable outcomes.
• The findings support the effectiveness and safety of ablation procedures in the region.
• Establishment of the registry provides a foundation for future research and quality improvement.
