Procedure
All patients were in AF before the procedure. Acute PVI was achieved in all patients. Two of them also had a history of common isthmus-dependent atrial flutter, so cavotricuspid isthmus ablation was also performed. Ablation lines were performed in three patients who presented atypical left atrial flutter during the procedure.
Median procedure time (from femoral venous puncture to removal of all catheters) was 169.3±29 minutes and median fluoroscopy time was 5.6±2.5 minutes.
The only complication derived from the procedure was one case of cardiac tamponade (4.3%) that was solved by pericardiocentesis.
