At 12 months, the bi-atrial cohort (median follow-up 609 days; monitoring: 75% implantable loop recorder, 25% Holter) demonstrated 85% freedom from persistent atrial arrhythmias, whereas the left-atrial cohort (median follow-up 1,348 days; monitoring: 15% implantable loop recorder, 45% transtelephonic monitoring, 35% Holter) demonstrated 60% freedom; favoring the bi-atrial strategy but this did not reach statistical significance (p=0.081).
