NCT05086861

Brief Summary

Patients undergoing hybrid AF ablation second stage catheter ablation have the posterior left atrium mapped to see it if is electrically isolated. This is done via a standard electrophysiogical study in accordance with routine clinical practice. Investigators propose to check left atrium posterior wall isolation via oesophageal pacing and compare this to findings from invasive study

Study Arms (1)

Oesophageal Pacing Arm

EXPERIMENTAL

Patients undergoing atrial fibrillation ablation to isolate the left atrial posterior wall via catheter or staged hybrid ablation.

Device: Oesophageal pacing after left atrial posterior wall isolation

Interventions

Following AF ablation with the aim of isolating the left atrial posterior wall oesophageal pacing and sensing is performed to check for left atrial posterior wall. entrance and exit block.

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female
  • Aged between 18 and 80 years
  • Undergoing ablation under general anaesthetic with planned isolation of the left atrial posterior wall or who have previously undergone either catheter or surgical ablation for AF with LA posterior wall isolation

You may not qualify if:

  • Unable or willing to give fully informed written consent
  • Turned down for general anaesthetic
  • Pregnancy
  • Terminal illness
  • Any other significant disease or disorder which, in the opinion of the investigator, may either put the participant at risk because of participation in the study, or may influence the result of the study, or the participant's ability to participate.
