Summary

This is a prospective, randomized, multi-center trial that aims to investigate whether termination of atrial fibrillation can be used as an ablation endpoint for persistent atrial fibrillation (PersAF). Eligible patients who provided consent were randomly assigned to one of two groups: the AF-termination group (whose ablation endpoint was the pursuit of AF-termination) or the prespecified-ablation group (whose ablation endpoint was prespecified ablation followed by electrical cardioversion).

Conditions

Interventions

PROCEDURE

AF-termination Group

Each center completes the ablation according to the above ablation procedure. The choice of ablation strategy is not restricted, but efforts should be made to achieve termination of AF during the ablation procedure. If cannot terminate AF for safety or other reasons involving difficulties to remap AFEGM or creating a complete conduction block despite the operator's best efforts, then direct current conversion (DCCV) was performed.

PROCEDURE

Prespecified-ablation Group

Each center completes the prespecified ablation according to the above ablation procedure. Although there is no restriction on the choice of ablation strategy, Ablation must be performed following the PVI plus strategy, which can be combined with one or more additional ablation procedures, but each ablation must achieve its own endpoints, such as bidirectional block of linear damage, posterior wall isolation, etc. After completing the preset ablation steps, DCCV will be performed. If AF is terminated after or during ablation, it is also considered the endpoint of ablation in this group, but the preset ablation steps must be completed.
