Why the study?
Does radiofrequency catheter ablation improve the maintenance of sinus rhythm in symptomatic patients with longstanding permanent atrial fibrillation?
Does radiofrequency catheter ablation improve the maintenance of sinus rhythm in symptomatic patients with longstanding permanent atrial fibrillation?
Catheter ablation is feasible for longstanding permanent AF, achieving sinus rhythm in 76% of patients at 8.4 months, but often requires multiple procedures and carries a significant complication rate.
No takes yet. Share an insight, caveat, or question.
May support ablation feasibility in longstanding permanent AF; leaves open need for randomized confirmation of efficacy and safety.
