Key result
New and developing ablation catheter technologies and mapping systems may improve outcomes and lower recurrence rates for persistent atrial fibrillation compared to standard pulmonary vein isolation.
Why the study?
Catheter ablation outcomes for persistent AF remain consistently lower than for paroxysmal AF, potentially due to non-durable lesions or non-PV targets.
This review highlights emerging ablation catheter technologies and mapping systems aimed at improving outcomes for persistent atrial fibrillation.
Should not yet change practice for persistent AF ablation; leaves open need for RCTs confirming lower recurrence with novel technologies.
Catheter ablation is commonly used for treatment of persistent atrial fibrillation (AF). Pulmonary vein isolation (PVI) is still the cornerstone for the procedure, however, outcomes are consistently lower compared to paroxysmal AF. It is hypothesized that it could be due to lack of durable lesions or the presence of non-PV targets that remain after PVI. Numerous advances in ablation catheter technologies and mapping systems may potentially achieve lower recurrence rates in the future. Ongoing research is required to discover the best technique for persistent AF ablation. The purpose of this review is to describe the new, developing technologies that may improve the outcome of this procedure in the persistent AF population.
