Spanish catheter ablation registry. 22nd official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2022).

INTRODUCTION AND

OBJECTIVES

This article presents results of the Spanish catheter ablation registry for the year 2022.

METHODS

Data were retrospectively entered into a REDCap platform using a specific form.

RESULTS

A total of 103 centers participated (75 public, 28 private), which reported 23 360 ablation procedures, with a mean of 227±173 and a median of 202 [interquartile range, 77-312] procedures per center. Activity significantly increased (+5419 procedures,+30.2%) with more centers participating in the registry (10 more than in 2021). The most common procedure continued to be atrial fibrillation ablation (35%, 8185 procedures) followed by cavotricuspid isthmus ablation (20%, 4640 procedures), and intranodal re-entrant tachycardia (17%, 3898 procedures). There was an increase in all reported substrates, especially atrial fibrillation ablation (+40%), with slightly higher global acute success (96%) and lower complication rates (1.8%) and mortality (0.04%, n=10). In total, 525 procedures were performed in pediatric patients (2.2%)

CONCLUSIONS

The Spanish catheter ablation registry systematically and continuously collects the national trajectory, which experienced a significant activity increase in 2022 in all of the reported substrates but especially in atrial fibrillation ablation. Acute success increased, while both complications and mortality decreased.
