Novel use of dynamic MR hydrography to rule out esophageal perforation post atrial fibrillation ablation in a patient with anaphylaxis to gadolinium.

Esophageal thermal injury is one of the most devastating complications of atrial radiofrequency ablation, and its diagnosis can be challenging. In this report, we highlight the novel use of free water as a contrast material to better visualize the esophageal lumen in a patient with anaphylaxis to Iodinated contrast media and Gadolinium who recently underwent atrial fibrillation ablation. This becomes particularly handy in patients with contrast allergy, and further emphasizes the role of multimodality imaging. [Display omitted] • MR hydrography is a novel technique that can be used for evaluation of esophageal perforation after RF ablation procedures. • This technique is useful in a subset of patients with contrast allergy in whom multimodality imaging evaluation is necessary. • This report forms the basis of a new imaging technique that could potentially be used in clinical practice in the future.
