Key result
Catheter ablation for long-standing persistent atrial fibrillation yields a single-procedure success rate of 20-60%, though multiple procedures can achieve 72-79% long-term control.
Why the study?
Restoring and maintaining sinus rhythm is difficult in long-standing persistent AF due to progressive electrical and structural remodeling, but technological and procedural advances are improving rhythm control outcomes.
This review highlights the evolving strategies and improving outcomes of rhythm control via catheter ablation in patients with long-standing persistent atrial fibrillation.

Requires careful patient selection; leaves open optimal strategies for randomized evaluation in long-standing persistent AF.
Long-standing persistent atrial fibrillation (L-PeAF) is a category in which rhythm control is attempted while atrial fibrillation (AF) is maintained for more than 1 year. Because AF is a progressive disease and L-PeAF accompanies significant electrical and structural remodeling of atria, it is difficult to restore and maintain sinus rhythm in patients with L-PeAF. Nonetheless, the rhythm outcome is being increasingly improved by the development of sophisticated mapping devices, highly efficient catheters, and evidence-based ablation strategies, and the rational choice of patient selection criteria. This review discusses the evolution of the rhythm control outcome of L-PeAF and its future direction of development.

Hui‐Nam Pak (2019) conducted a review in Long-standing persistent atrial fibrillation. Catheter ablation was evaluated. Catheter ablation for long-standing persistent atrial fibrillation yields a single-procedure success rate of 20-60%, though multiple procedures can achieve 72-79% long-term control.
