Summary

We aimed to assess the benefit of epicardial mapping and ablation in patients with recurred atrial tachyarrhythmias after single procedure for atrial fibrillation. We hypothesize that both endocardial and epicardial approach is superior to only endocardial approach with regards to clinical recurrence. Participants are randomized into a hybrid approach or an endocardial approach.

Conditions

  • Persistent Atrial Fibrillation

Interventions

PROCEDURE

hybrid approach

Before transseptal puncture, epicardial puncture is performed through subxyphoid approach. Atrial epicardial potentials are recorded using multi-electrode catheter, leading an activation map for atrial tachycardia and map for continuous fractionated atrial electrograms during atrial fibrillation. Endocardial potentials are also recorded in the same fashion. Procedural endpoint is a tachycardia termination or a noninducibility of tachycardia.

PROCEDURE

conventional endocardial approach

Atrial endocardial potentials are recorded using multi-electrode catheter, leading an activation map for atrial tachycardia and map for continuous fractionated atrial electrograms during atrial fibrillation. Procedural endpoint is a tachycardia termination or a noninducibility of tachycardia.
