Resumen:
Introduction and objectives. This article reports the findings of the 2009 Spanish national Catheter Ablation Registry.
Methods. Data were collected in two ways: retrospectively using a standard questionnaire and prospectively from a central database. Each center chose its own preferred method of data collection.
Results. Data were collected from 59 centers. The total number of ablation procedures carried out was 8546, giving a mean of 145 101 procedures per center. The three most frequently treated conditions were atrioventricular nodal reentrant tachycardia (n=2341; 27%), typical atrial flutter (n=1859; 21.7%) and accessory pathways (n=1758; 20.5%). The fourth most common condition was atrial fibrillation (n=1188; 14%), the number of which has grown by 44% since the 2008 registry. The overall success rate was 93%, major complications occurred in 1.9%, and the mortality rate was 0.046%.
Conclusions. Data from the 2009 registry show that the number of ablations carried out continued to increase and exceeded 8000 for the first time. In addition, they show, in general, a higher success rate and a lower number of complications. Cavotricuspid isthmus ablation, as treatment for typical atrial flutter, continued to be the second most common procedure. There was a substantial increase in the number of catheter ablations performed for atrial fibrillation compared with previous years.
