2017 AF Symposium: Preventing Esophageal Fistula
The Problem: During an ablation, doctors take great precautions to not heat or injure the esophagus which lies behind the posterior wall of the left atrium. Injuring the esophagus can, in very rare cases, cause an atrial esophageal fistula which can be fatal.
Fear of causing esophageal injury can cause the EP to modify the ablation lesion set delivery, thereby reducing ablation success.
New Solution: an Esophagus displacement tool.
The EsoSure Esophageal Retractor allows doctors to re-position a section of the esophagus away from the nearby heart tissue and avoid the heat generated during ablation.
Live streaming ablation: In this re-do ablation, entrainment (pacing) mapping was used to identify non-PV triggers.
Since they had to ablate in the posterior of the left atrium next to the esophagus, they simply moved the EsoSure Retractor up and down to displace the esophagus. The EPs remarked they could now ablate at a higher wattage without fear of harming the esophagus. …continuing reading my report…
