Outcomes
The primary endpoint was a composite of
stroke, all-cause mortality, and
cardiovascular hospitalization. The secondary endpoint was AF recurrence
after single ablation. Stroke was defined as sudden neurologic
dysfunction caused by brain ischemia attack. Cardiovascular
hospitalization was defined as hospitalization caused by heart failure,
AF, and other cardiovascular conditions. However, scheduled admission
for a redo procedure was not included. The recurrence of AF was defined
as any symptomatic or asymptomatic documented atrial tachyarrhythmia
(AF, atrial tachycardia, atrial flutter) lasting for >30
seconds after a 3-month blanking period of the ablation.
