摘要
目的 分析三维超声心动图量化评价射频消融术治疗心房颤动的效果.方法 选取郑州市第七人民医院2021年1月至2023年6月收治的40例心房颤动患者,入院时接受射频消融术治疗,选取同期健康体检者40例(对照组)作为研究对象,通过三维超声心动图检测,评价手术前后患者的左心、右心功能.结果 心房颤动患者术前肺静脉收缩期S波流速(PVS)、舒张期D波流速(PVD)、左室射血分数(LVEF)、左心房主动射血分数(LAAEF)、左心房被动射血分数(LAPEF)均低于对照组,右室心肌做功指数(RMPI)、右室收缩末期容积(RVESV)、右室舒张末期容积(RVEDV)均高于对照组,右心室射血分数(RVEF)低于对照组,差异有统计学意义(P<0.05),术后3个月时PVS、PVD、LVEF、LAAEF、LAPEF、RVEF均高于术前,E/A、收缩末期左心房最大容积(LVAmax)、最小容积(LVAmin)、RMPI、RVESV、RVEDV值均低于术前,差异有统计学意义(P<0.05).结论 采用实时三维超声心动图,可准确测量患者术后心功能改善情况,为临床治疗评估提供参考依据.
Abstract
Objective To analyze the clinical efficacy of real-time three-dimensional echocardiography for quantitative evaluation of radiofrequency ablation in patients with atrial fibrillation.Methods Forty patients with atrial fibrillation admitted to Zhengzhou Seventh People's Hospital from January 2021 to June 2023 were treated with radiofrequency ablation upon admission.Forty healthy individuals who underwent physical examinations during the same period(control group)were selected as the study subjects.Three dimensional echocardiography was used to evaluate the left and right heart function of the patients before and after surgery.Results Preoperative pulmonary vein harvesting S-wave velocity(PVS),diastolic D-wave velocity(PVD),left ventricular ejection fraction(LVEF),left atrial active ejection fraction(LAAEF),and passive ejection fraction(LAPEF)in patients with atrial fibrillation were all lower than those in the control group.Right ventricular myocardial performance index(RMPI),right ventricular end systolic volume(RVESV),and right ventricular end diastolic volume(RVEDV)were all higher than those in the control group.Right ventricular ejection fraction(RVEF)was lower than that in the control group,and the differences were statistically significant(P<0.05).Three months after surgery,PVS,PVD,LVEF,LAAEF,LAPEF,RVEDV were all higher than preoperative values,while E/A,end systolic left atrial maximum volume(LVAmax),minimum volume(LVAmin),RMPI,RVESV,RVEDV values were lower than preoperative values,with statistically significant differences(P<0.05).Conclusion Real time three-dimensional echocardiography can accurately measure the postoperative cardiac function improvement of patients,providing a reference basis for clinical treatment evaluation.
