Key result
Late after intraoperative radiofrequency ablation of atrial fibrillation, sustained stable secondary arrhythmias were documented in 6.2% of patients during long-term follow-up.

What is the incidence and mechanism of stable secondary arrhythmias late after intraoperative radiofrequency ablation of atrial fibrillation?
Late after intraoperative RF ablation for atrial fibrillation, stable secondary arrhythmias occur in approximately 6% of patients, often due to noncontinuous or nontransmural linear lesions requiring further interventional therapy.
No takes yet. Share an insight, caveat, or question.
Long-term monitoring for secondary arrhythmias may be warranted after intraoperative AF ablation; leaves open optimal lesion strategies in this Level 3 cohort.
Kobza et al. (2004) conducted a cohort in Atrial fibrillation (n=129). Intraoperative radiofrequency (RF) ablation was evaluated on Sustained stable secondary arrhythmias. Late after intraoperative radiofrequency ablation of atrial fibrillation, sustained stable secondary arrhythmias were documented in 6.2% of patients during long-term follow-up.
