May support ablation for late atrial tachycardia after AF surgery; leaves open need for randomized confirmation.
What are the mechanisms of late postoperative atrial arrhythmias after atrial fibrillation surgery, and is radiofrequency catheter ablation effective for their management?
Late postoperative arrhythmias after atrial fibrillation surgery occur in approximately 15% of patients, are typically reentrant, and can be highly effectively managed with radiofrequency catheter ablation.
McElderry et al. (2007) studied this question.
