Abstract

The presence of atrial fibrillation (AF) is associated with a 5-fold increase in the risk of stroke, the development of heart failure, and a decrease in the quality of life. Muscle sleeves located in the mouths of the pulmonary veins are a source of ectopic activity that causes and maintains AF. The posterior wall of the left atrium has electrophysiological properties similar to the sleeves, which can cause and maintain AF. Thus, isolation of the posterior wall of the left atrium may improve the results of catheter treatment for AF. There are several strategies for performing catheter ablation aimed at achieving isolation of the posterior wall of the left atrium (single ring, box lesion set, debulking), each of which has its own advantages and disadvantages, which are discussed in this review. It also provides data on possible complications associated with the anatomical features of the relationship between the posterior wall of the left atrium and the esophagus. There is conflicting evidence of the clinical efficacy of
