摘要: 目的 评估心房颤动(房颤)患者导管消融术中将活化凝血时间(ACT)维持于略低于指南建议范围的安全性。方法 连续纳入行房颤射频消融术的1065例患者,单次房间隔穿刺成功后根据体重给予100 U/kg的首剂肝素,之后每15~20 min测量1次ACT,根据ACT测值每次追加1000~2000 U肝素,ACT目标范围为220~270 s。应用冷盐水灌注消融导管进行肺静脉隔离和左房消融。结果 术中的ACT均值为(234.6±30.4) s,平均手术时间(145.8±36.7) min,术中平均肝素用量为(11 092.0±2297.6) U。在并发症方面,1例(0.09%)发生了围术期症状性脑栓塞,10例(0.9%)发生了急性心脏压塞。结论 在应用单次房间隔穿刺和冷盐水灌注消融导管的条件下,房颤射频消融术中ACT均值维持于低于指南建议的范围并不增加围术期血栓栓塞事件。Abstract: Objective To evaluate the perioperative safety of maintaining a lower active coagulation time (ACT) compared to the guidelines recommendation during the catheter ablation for patients with atrial fibrillation(AF).Methods The 1065 consecutive patients with AF underwent catheter ablation using an irrigatedtip catheter with a single left atrial long sheath. After an atrial septal puncture, a weight-based heparin bolus of 100 U/kg was given. Then, the ACT was checked every 15-20 min and additional 1000-2000 U heparin was infused if needed. The target ACT range was 220-270 s.Results he total heparin dose and the mean intra-procedural ACT were (11 092.0±2297.6) U and(234.6±30.4) s, respectively, with the mean procedure time of (145.8±36.7) min. Severe complications included 1(0.09%) symptomatic cerebral embolism and 10(0.9%) acute cardiac tamponades.Conclusion A intra procedural ACT target that is lower than the guidelines recommendation may not increase the peri-procedural thromboembolic events for patients who underwent catheter ablation in AF.
