目的为进一步提高心房颤动(简称房颤)导管消融手术成功率并降低并发症,分别对比使用SmartTouch压力感应导管与普通冷盐水灌注NaviStar导管进行房颤导管消融。方法共纳入100例房颤患者,分为对照组(NaviStar,n=50)和研究组(SmartTouch,n=50),两组均在Carto三维标测系统下进行双侧肺静脉隔离。采集两组患者的一般资料、手术时间、X光曝光时间,观察术后窦性心律维持率,比较两组之间的差异。结果两组患者总手术时间、左房建模时间、并发症发生无统计学差异。研究组X线曝光时间较短[(25.4±5.3)min vs(38.7±7.5)min]、肺静脉隔离时间较短[(59±13)min vs(72±16)min],术后3个月(47/50vs 44/50)、术后半年(46/50vs37/50)、术后1年(46/50vs 32/50)窦性心律维持率均优于对照组(P均<0.05)。结论 SmartTouch压力导管能提高手术成功率。
Objective To further improve the success rate of catheter ablation and reduce the complications of atrial fibrillation (AF), we compared the catheter ablation of atrial fibrillation with the SmartTouch pressure-sensing catheter and the ordinary saline-infused NaviStar catheter respectively. METHODS: A total of 100 patients with atrial fibrillation were enrolled and divided into control group (NaviStar, n = 50) and study group (SmartTouch, n = 50). Both groups were subjected to bilateral pulmonary vein isolation under the Carto 3D mapping system. The general data, operation time and X-ray exposure time of two groups of patients were collected, and the maintenance rate of sinus rhythm after operation was observed. The differences between the two groups were compared. Results There was no significant difference in total operation time, left atrium modeling time and complications between the two groups. The X-ray exposure time was shorter in the study group [(25.4 ± 5.3) min vs (38.7 ± 7.5) min), shorter pulmonary vein isolation time (59 ± 13) min vs (72 ± 16) min, and postoperative 3 months (47/50 vs 44/50), half a year postoperatively (46/50 vs 37/50), and one-year postoperative 46/50 vs 32/50 (all P <0.05). Conclusion SmartTouch pressure catheter can improve the success rate of surgery.
