This study presents a novel technique for the treatment of a deep esophageal ulcer after ablation of paroxysmal atrial fibrillation (AF). Pulmonary vein isolation was performed using a radiofrequency irrigated tip catheter. On Day 5 of follow-up, a deep esophageal ulcer was observed. No significant visual improvement was observed after conventional treatment. Endoscopic negative pressure therapy in the esophagus was then applied for 5 days. A significant decrease in diameter and depth of the lesion was observed, possibly preventing perforation. Endoscopic negative pressure therapy can be used to heal thermal lesions after AF ablation procedures.
本研究提出了一种新的技术，用于治疗阵发性心房颤动（AF）消融后深部食管溃疡。使用射频灌流导管进行肺静脉隔离。在随访的第 5 天，观察到深部食管溃疡。常规治疗后未见明显改善。随后对食管进行内镜下负压治疗 5 天。观察到病变的直径和深度明显减小，可能防止了穿孔。内镜下负压治疗可用于治疗 AF 消融术后的热损伤。
