[Spanish Catheter Ablation Registry. Fifth official report of the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias (2005)].
OBJECTIVE
The findings (i.e., success and complication rates) of the 2005 Spanish Catheter Ablation Registry, as prepared by the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias, are presented.


METHODS
As in previous years, data were collected in two ways: retrospectively using a standardized questionnaire sent to electrophysiology laboratories by the Working Group on Electrophysiology and Arrhythmias, and prospectively from a central database. Each participating center selected its own preferred method of data collection.


RESULTS
Forty-seven centers contributed data to the registry. A total of 6162 ablation procedures were analyzed, averaging 131 (88) per center. As in previous reports, the three main conditions treated were atrioventricular nodal reentrant tachycardia (n=1795, 29%), accessory pathways (n=1591, 26%), and typical atrial flutter (n=1378, 22%). Atrial fibrillation was the fourth most common condition treated (n=480, 8%). The overall success rate was 93%, major complications occurred in 1.05%, and the mortality rate was 0.03%.


CONCLUSIONS
With more than 6000 ablation procedures recorded and with the participation of a greater number of centers throughout the country, the Spanish Catheter Ablation Registry is becoming increasingly representative and is consolidating its value as a point of reference. The number of catheter ablations carried out for atrial fibrillation in Spain is continuing to grow.
