摘　　要：目的探讨心腔内超声技术(ICE)在心房颤动中的应用。方法选取临汾市人民医院2022年2月至2023年2月收治的阵发性心房颤动患者60例为研究对象,按照术中是否使用ICE分为2组,研究组(采用ICE导管)和对照组(不采用ICE导管),每组30例。研究组使用ICE导管进行房间隔穿刺,对照组在传统X线下行房间隔穿刺。对两组的房间隔穿刺时间、手术整体时长、X线曝光时间以及消融成功率等进行比较。结果共60例随机分配的患者被纳入采用意向治疗人群,按1∶1比例随机分为研究组及对照组各30例。研究组对比对照组的X线曝光计量明显减少[(16.2±6.2)mGy比(80.7±8.2)mGy,P<0.05],在总体手术时间上研究组有所减少[(150.3±5.4)min比(168.3±4.9)min,P<0.05];两组1年维持窦性心律比率以及术后并发症的差异无统计学意义(P>0.05)。结论ICE导管在阵发性心房颤动的射频消融手术中可以降低X线曝光时间以及曝光计量,取得较好的临床效果,而且大大减少手术时长且不增加并发症。Objective To explore the application of intracardiac echocardiography(ICE)in radiofrequency ablation surgery for patients with atrial fibrillation.Methods Sixty patients with paroxysmal atrial fibrillation admitted to the Linfen People’s Hospital from February 2022 to February 2023 were selected as the study subjects.They were randomly divided into two groups based on whether ICE catheters were used during the surgery:the study group(using ICE catheters)and the control group(not using ICE catheters),with 30 patients in each group.ICE catheter was used in the research group for atrial septal puncture,while traditional X-ray was used in the control group for atrial septal puncture.The atrial septal puncture time,overall surgical duration,X-ray exposure time,and ablation success rate between the two groups were compared.Results A total of 60 randomly assigned patients were included in the intention-to-treat population.They were randomly divided into the study group and the control group at a 1∶1 ratio,with 30 patients in each group.The X-ray exposure measurement in the study group was significantly reduced compared to the control group[(16.2±6.2)mGy vs.(80.7±8.2)mGy,P<0.05],and the overall surgical time in the study group was reduced[(150.3±5.4)min vs.(168.3±4.9)min,P<0.05].There was no statistically significant difference in the 1-year maintenance of sinus rhythm ratio and postoperative complications between the two groups(P>0.05).Conclusion ICE can reduce X-ray exposure time and exposure dose in radiofrequency ablation surgery for patients with paroxysmal atrial fibrillation,achieve good clinical results and greatly reduce surgical duration without increasing complications.
