    BackgroundThe initial experience with left atrial esophageal fistula (LAEF) secondary to atrial fibrillation (AF) ablation procedures revealed a near-universal mortality. A comprehensive description of the principles of LAEF repair in the modern era and its resulting impact on morbidity and mortality are lacking in the literature.ObjectiveTo describe the presentation, surgical management, and outcomes of patients with LAEF.MethodsA retrospective cohort analysis of 29 patients was performed, including previously unpublished cases of surgically repaired LAEF from 4 institutions (n = 6), and all published cases of surgically repaired (n = 16) or stented (n = 7) LAEF.ResultsThe mean age was 55 ± 13 years, and 75% were men who were undergoing radiofrequency energy catheter ablation (n = 26), cryoablation (n = 1), high-intensity focused ultrasound ablation (n = 1), and surgical mini-MAZE procedure (n = 1) and presented 30 ± 12 days postablation procedure. Overall, 55% of the patients receiving an intervention for LAEF died (41% surgical repair; 100% stent). Patients who did not receive primary esophageal repair were more likely to experience postoperative complications, including mediastinitis, need for percutaneous endoscopic gastrostomy (PEG) feeds, esophageal stent, or death (P = .05). In addition, interposing tissue between the repaired esophagus and the left atrium resulted in fewer postoperative complications (P = .02).ConclusionsWhile improved relative to initial reports, mortality associated with LAEF remains high after corrective intervention. Primary esophageal repair with the placement of tissue between the repaired esophagus and the left atrium may result in lower morbidity and mortality.© 2013 Heart Rhythm Society.
