Detailed analysis of the relationship between the left atrium and esophagus in patients prior to catheter ablation of atrial fibrillation: an analysis using 3D computed tomography

Original language description

Background. Damage to the esophagus during radiofrequency ablation of atrial fibrillation can result in fatal atrioesophageal fistula. Our aim is to describe the relationship of the left atrium (LA) and esophagus with a focus on contact of the posterior wall (PW) of the LA and the esophagus. Methods. From 9/2011 to 8/2012, CT of the heart was performed in 56 patients undergoing catheter ablation of atrial fibrillation using CT GE Lightspeed VCT 64 by nongated standard protocol. Positions of the esophagus to the LA, width of the esophagus and contact with the PW of the LA were determined. Results. The most frequent position of the esophagus was behind the left side of the LA. The average width of the esophagus was 16.0 +- 4.1 mm, and the average distance between the PW and esophagus was 4.8 +- 1.6 mm. On average, 50 +- 4.11 mm of the PW was in close contact with the esophagus. The average length of the fat pad between the esophagus and LA was 9.1 +- 5.5 mm in the upper part of the LA and 15.8 +- 7.3 mm at the bottom. Significantly longer contact occurred behind the right part of the LA. Conclusions. The most common esophageal position is behind the left side of the LA. The esophagus is located in close contact by approximately 2/3 of the length and 1/4 of the width of the PW of the LA. The esophagus is more adjacent to the upper part of PW of the LA
