Severity of esophageal injury predicts time to healing after radiofrequency catheter ablation for atrial fibrillation

摘要: Background The delivery of radiofrequency (RF) energy to the posterior left atrium creates a risk injury adjacent esophagus. Esophageal endoscopy (EGD) is used screen patients at for esophageal thermal after RF ablation. Objective purpose this study was analyze macroscopic features severity injuries induced by ablation as seen EGD and evaluate association these descriptions with time elapsed until complete healing. Methods This analyzed 219 undergoing atrial fibrillation. temperature probes were during each ablation, performed in cases intraesophageal ≥39°C. Repeat obtained 10 days healing all demonstrating injury. Serial endoscopies repeated every 2 weeks documented. Lesions classified according superficial or deep ulceration; size shape also noted. Results We found 37.4% (82 219) intraluminal temperatures Of these, 22 (27%) identified injury, 68% being ulcerations 32% deep. On repeat days, only 29% healed, compared 87% (P = .0136). No difference when shape. Conclusions lesions detected on day can predict resolution, severe, requiring longer heal.
