| 目的 应用实时三维超声心动图(RT-3DE)定量评价冠心病、扩张型心肌病患者左心室、左心房、右心室和右心房容积及收缩功能。方法 在24例正常人、16例扩张性心肌病和27例心肌梗死患者中,应用实时三维超声心动图获取各房室全容积三维图像,分别应用2、4、8平面方法测量各房室收缩末期容积(ESV)、舒张末期容积(EDV)和射血分数(EF),并与二维超声心动图(2DE)Simpson法和声学定量(AQ)技术测值比较。结果 在扩张性心肌病和心肌梗死患者中,2DE、AQ技术和RT-3DE 2平面法测量的左、右心房和左、右心室ESV、EDV明显低于RT-3DE 4平面法、8平面法测值(P＜0.05);各种方法检测的EF值差异无统计学意义(P＞0.05)。2DE、AQ技术和RT-3DE检测结果均显示扩张性心肌病、心肌梗死患者各房室ESV、EDV均明显大于正常组(P＜0.05),EF明显低于正常组(P＜0.05)。结论 应用实时三维超声心动图能显示心腔立体结构,测量各心腔容积,评价心脏功能。 |
| 英文摘要: |
| Objective To quantify the volumes and ejection fractions of left atrium (LA), right atrium(RA) and left ventricle(LV), right ventricle(RV) in patients with coronary artery disease and cardiomyopathy by using Real-time three-dimensional echocardiography (RT-3DE). Methods RT-3DE data of 24 normal controls, 27 patients with coronary artery disease and 16 patients with cardiomyopathy were acquired using RT-3DE. End diastolic volume (EDV) and end systolic volume (ESV) of LV, LA, RV and RA were measured using RT-3DE 2-, 4-, 8-plane methods, 2DE Simpson method and AQ technique. Results The volumes of LV, LA, RV, RA measured by 3DE 2-plane, 2DE, AQ were significantly smaller than those of 3DE 4-and 8-planes (P＜0.05). ESV, EDV of LV, LA, RV, RA in the patients with coronary artery disease and cardiomyopathy were significantly larger than those of the controls, and EF was smaller(P＜0.05). Conclusion RT-3DE could display heart space frame all-round and measure atrial and ventricular volumes and ejection fractions accurately. |
