Do novel esophageal imaging techniques help avoid ablation in left atrial tissue overlapping the esophagus during atrial fibrillation ablation?
Novel esophageal imaging techniques using barium cream with gadolinium during MRA or CTA, as well as electroanatomic mapping, can help avoid ablation in left atrial tissue overlapping the esophagus during AF ablation.
This report describes different imaging techniques of the esophagus in four patients during radiofrequency catheter ablation of atrial fibrillation in the left atrium. A novel use of a mixture of barium cream and gadolinium diglutamate allowed esophageal imaging during magnetic resonance angiography of the left atrium and pulmonary veins. Barium cream used during computer tomography angiographic imaging of the left atrium and pulmonary veins allowed esophageal imaging. The esophagus was also imaged with an electroanatomic mapping system. Esophageal and left atrial imaging helped to avoid catheter ablation in left atrial tissue overlapping the esophagus.
Pollak et al. (Mon,) conducted a case report in Atrial fibrillation (n=4). Esophageal imaging techniques (barium cream, gadolinium diglutamate, electroanatomic mapping) was evaluated on Avoidance of catheter ablation in left atrial tissue overlapping the esophagus. Novel esophageal imaging techniques using barium cream and gadolinium diglutamate during MRA, CTA, and electroanatomic mapping helped avoid ablation in left atrial tissue overlapping the esophagus.
