室间隔缺损封堵术后左心功能的超声评价

目的应用超声心动图评价Amplatzer封堵器治疗室间隔缺损(VSD)患者于封堵术前后左心功能的变化。方法观察28例VSD患者封堵术前、术后1个月和术后6个月左室舒张末期内径(EDD)、舒张末期容积(EDV)、收缩末期容积()ESV、每搏输出量()SV、射血分数()和短轴缩短率()大小及变化。结果封堵术后1个月较术前差异具有显著性意义,EDDEFFS(P<0.05),EDV(P<0.001)ESV(P<0.05)SV(P<0.001)EF,FS无明显变化;封堵术后6个月,6项指标均恢复正常,较,,,术前差异具有显著性意义(P<0.001)。结论超声引导下VSD封堵术能够有效的改善VSD患者的左心功能。

Evaluation on the left ventricular funcion in transcatheter closure of ventricular septal defects with echocardiography

Objective To compare the change of left ventricular function before and after closure of ventricular septal defects(VSD) in transcatheter.Methods The inner diameter of left ventricular end-diastole(EDD),left ventricular end-diastolic volume(EDV),end-systolic volume(ESV),stroke volume(SV),ejection fraction(EF)and fraction shortening (FS) in 28 patients with VSD were measured before,after 1 month and 6 months transcatheter closure of ventricular septal defects(TCVSD) by color echocardiography.Results TCVSD after 1 month compared with before,the figures of EDD (P< 0.05),EDV(P< 0.001),ESV(P< 0.05),SV(P< 0.001)were significant difference,but there no significant difference in EF and FS.After 6 months,all figures decreased to normal(P< 0.001).Conclusion TCVSD is an effective treatment in patients with VSD and can improve left ventricular function.
