Background: This report describes the findings of the 2019 Italian Catheter Ablation Registry of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC). Methods: Data collection was retrospective. A standardized questionnaire was completed by each of the participating centers. Results: A total of 15 201 ablation procedures were performed by 91 institutions. Most (78%) of the centers has one electrophysiology laboratory, and 17% of them has a hybrid cardiac surgery laboratory. Almost all (98%) centers have a 3D mapping system. The median number of electrophysiologists and nurses involved in the electrophysiology laboratory was 3 and an electrophysiology technician was involved in 30% of all centers. In 88.4% of cases, ablations were performed for supraventricular arrhythmias, and among these the most frequently treated arrhythmia was atrial fibrillation (32.9%), followed by atrioventricular nodal reentrant tachycardia (23.9%), and common atrial flutter (11.7%). In 10 256 (67.4%) patients catheter ablation was performed by means of a 3D mapping system, with a "near-zero" fluoroscopic approach in 4626 (30.4%) of all patients. Conclusions: The 2019 Italian Catheter Ablation Registry confirmed that atrial fibrillation is the most commonly treated arrhythmia in the ablation centers with an increasing number of procedures performed with a 3D mapping system and a "near-zero" approach.
