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.
本报告描述了4例患者在左心房房颤射频导管消融术期间对食管采用的不同成像技术。一种新型的硫酸钡乳膏和钆双谷氨酸混合物的应用，使得在左心房和肺静脉磁共振血管造影期间能够对食管进行成像。在左心房和肺静脉计算机断层血管造影成像期间使用硫酸钡乳膏可实现食管成像。食管也通过电解剖标测系统进行成像。食管和左心房成像有助于避免在与食管重叠的左心房组织中进行导管消融。
