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.
