Why the study?
Does duty-cycled phased-radiofrequency ablation increase the incidence of cerebral embolism compared to cooled-radiofrequency during atrial fibrillation ablation?

While PVAC Gold ablation for atrial fibrillation increases asymptomatic cerebral emboli and microembolic signals compared to cooled-radiofrequency, it does not appear to cause measurable neuropsychological deficits.

PVAC Gold raises silent emboli during PVI; challenges its safety versus cooled RF and leaves clinical relevance of ACE unresolved.
PVI with the new PVAC Gold was associated with a higher incidence of ACE/cerebral infarcts and number of MES. Both catheters induced a comparable procoagulant state. Because there were no measurable differences in neuropsychological status, the clinical significance of ACE remains unclear.
