Twenty-eight patients from a single surgeon and center underwent atrial fibrillation surgery using a diode-pumped laser. A left-sided modified (pulmonary vein encircling with connecting lesions) or a complete modified Cox-Maze III operation was employed. Of the 28 patients, 23 were available for retrospective evaluation and Holter monitoring, and 21 patients elected to participate in a follow-up study. The Society for Thoracic Surgeons database was used for in-hospital experience. All 21 patients were studied >6 months after surgery and received a 24-hour Holter monitor and an SF-36v2 quality of life survey. The mean follow-up time was 18.1 months. Among this group, one patient was in atrial fibrillation and four experienced atrial tachyarrhythmias at the time of Holter monitoring. Five patients (24%) underwent cardioversion after operation, and nine patients (43%) were on warfarin. No patients were treated with repeat ablation. One patient required a pacemaker postoperatively. We observed 95% freedom from atrial fibrillation and 76% freedom from all atrial tachyarrhythmias in the study group. No complications or deaths were device related. In conclusion, the use of a diode-pumped laser appears to be safe and effective for the treatment of atrial fibrillation.
来自单一外科医生和中心的28名患者接受了使用二极管泵浦激光的房颤手术。采用了左侧改良术式（环绕肺静脉并连接病变）或完整的改良Cox-Maze III手术。28名患者中，23名可进行回顾性评估和动态心电图监测，21名患者选择参加随访研究。使用胸外科医师协会数据库获取住院经验。所有21名患者在术后6个月以上接受研究，接受了24小时动态心电图监测和SF-36v2生活质量调查。平均随访时间为18.1个月。在该组中，1名患者在动态心电图监测时处于房颤状态，4名经历了房性快速性心律失常。5名患者（24%）术后进行了心脏复律，9名患者（43%）服用华法林。无患者接受重复消融治疗。1名患者术后需要起搏器。我们观察到研究组中95%的患者无房颤，76%的患者无所有房性快速性心律失常。无与器械相关的并发症或死亡。总之，使用二极管泵浦激光治疗房颤似乎是安全有效的。
