Study summary

Pulmonary vein isolation emerged as an effective and safe strategy to treat atrial fibrillation patients. Atrio-oesophageal fistula (AOF) represents a rare but devastating complication of AF ablation procedure. This complication (0.016-0.07%) requires an international effort to allow for better understanding of the factors contributing to its occurrence and the best management strategies. A worldwide, retrospective, multicenter registry focusing on the incidence, diagnosis and management of this complication.

Read the detailed description

Data about the incidence, optimal management and outcome of AOF is sparse. The largest national and international surveys report on less than 50 AOF. The latest worldwide survey was conducted in 2015 and managed to include 31 patients who developed AOF after atrial fibrillation ablation procedure. In the meanwhile, the total number of AF ablation procedures increased significantly. Additionally, AF ablation technology changes significantly with e.g. increasing numbers of cryoballoon ablation and contact force guided radiofrequency ablation.

The study is designed as a worldwide, multi-centre, anonymised registry study to evaluate the incidence, optimal management and outcome of this AOF. More than 50 patients with AOF following percutaneous catheter ablation will be included in the register.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 19, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
