Atrial fibrillation (AF) ablation has been shown to be possible using minimal or no fluoroscopic imaging for guidance. However, the techniques previously described focus on radiofrequency ablation or rely on the use of resource-heavy technology such as intra-cardiac echocardiography. We describe the first reported case in the literature of successful fluoroscopy-free AF cryoablation guided solely by transoesophageal echocardiography (TOE).

Case summary:

A 65-year-old gentleman underwent cryoablation of paroxysmal AF using TOE guidance only with no use of fluoroscopy. Transoesophageal echocardiography was used in all stages of the procedure including guidance for transseptal puncture, ensuring balloon position in the pulmonary veins, and checking for post-procedure pericardial effusion. After 5 months of follow-up, the patient remains in sinus rhythm and has discontinued all antiarrhythmic and anticoagulant medication.


This case demonstrates for the first time the feasibility of fluoroscopy-free cryoablation using only TOE for guidance.
