Oesophageal injury following magnetically guided single-catheter ablation for atrial fibrillation: insights from the MAGNA-AF registry

Magnetically guided CA for AF with careful energy titration at the posterior LA wall and no oesophageal temperature monitoring is not associated with an increased incidence of oesophageal thermal injury. The routine use of periprocedural TOE may cause a low rate of mechanical oesophageal lesions but reliably prevents major complications like transient ischaemic attack, stroke, or cardiac tamponade. An observed high prevalence of upper digestive system inflammation (63%) may further support the recommendation for a routine post-interventional treatment with a proton-pump-inhibitor.
