Atrial Fibrillation
Conditions
Interventions
1. To apply a high density mapping catheter (64 poles) on the epicardial side of the atrium, facing the endocardial catheter routinely used for electrophysiological exploration of AF
2. To compare offline the corresponding tracings.

Eligibility
Inclusion criteria
Inclusion criteria: All patients who have signed an informed consent and who are admitted for RF ablation of AF in the "hybrid Operating Room" (HOR). Ablation of AF in HOR require an endocardial and epicardial approach through thoracoscopy, allowing concommittant access to endo and epicardial side of the atrial wall
Exclusion criteria
Exclusion criteria: 1. Patients that didn't give their consent; 2. Patients that don't speak Dutch; 3. Patients that are not will competent.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. To demonstrate endo-epicardial electrical dissociation (EED) in human atrial fibrillation by recording simultaneously endocardial and epicardial surface; 2. To study epicardial conduction pattern in areas overlaying endocardial CFAE’s. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. To study the relationship between EED and CFAE’s; 2. To study the difference in occurrence of EED and CFAE’s between patients with paroxysmal AF (PAF-group) and patients with persistent/longstanding persistent AF (AF-group); 3. To discriminate different types of CFAE and identify those who most likely contribute to AF perpetuation. | — |
