| 目的 观察利用实时三维超声心动图(RT-3DE)评估、比较成年人正常心脏左右心室的可行性,并探讨左右心室之间的关系。 方法 应用RT-3DE全容积成像采集58名心脏正常成年人的心脏三维数据,在TomTec工作站中分析获得右心室舒张末期容积(EDV)、收缩末期容积(ESV)、每搏输出量(SV)和射血分数(EF);在Qlab工作站中分析获得左心室舒张末期容积(EDV)、收缩末期容积(ESV)、每搏输出量(SV)和射血分数(EF)。 结果 右心室EDV[(85.84±20.82)ml]、ESV[(41.87±10.48)ml]分别大于左心室EDV[(69.37±17.83)ml]、ESV[(26.46±8.26)ml] (P均<0.001),而右心室EF[(50.94±5.57)%]小于左心室EF[(61.97±6.48)%,P<0.001]。左心室SV[(42.91±11.72)ml]与右心室SV[(43.96±12.15)ml]差异无统计学意义(P=0.273)。左右心室的对应参数均有相关性。 结论 RT-3DE是评估左右心室容积和功能的可行方法,且其相应参数在左右心室间是相关的。 |

| Objective To assess the feasibility of real-time three-dimensional echocardiography (RT-3DE) in evaluation on the right and left ventricle of normal heart in adult, and to observe the relationship between the two ventricles. Methods Full-volume imaging of RT-3DE was performed in 58 adults with normal heart to collect 3D database of the heart. Then the database was transmitted to the workstation and analyzed. The right ventricular end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV) and ejection fraction (EF) were obtained in TomTec workstation, while the left ventricular end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV) and ejection fraction (EF) were obtained in QLab workstation. Results The right ventricular EDV([85.84±20.82]ml) and ESV ([41.87±10.48]ml) were higher than left ventricular EDV ([69.37±17.83]ml and ESV ([26.46±8.26]ml), respectively (P<0.001), but right ventricular EF ([50.94±5.57]%) was lower than left ventricular EF ([61.97±6.48]%, P<0.001). There was no significant difference between left ventricular SV ([42.91±11.72]ml) and right ventricular SV ([43.96±12.15]ml, P=0.273). Correlations were found among the corresponding parameters of right and left ventricle. Conclusion RT-3DE is a feasible method to evaluate the volume and function of right and left ventricle. The corresponding parameters of right and left ventricle are all related. |
