| 目的 应用单心动周期实时三维超声心动图(sRT-3DE)技术分析房间隔缺损(ASD)的分流量及其影响因素。方法 选取30例不合并轻度以上瓣膜反流的单纯继发孔型ASD患者为研究对象,应用sRT-3DE技术获得左、右心室的实时三维图像,采用Va15a分析软件自动测量出右心室及左心室每搏量即肺循环血流量(QpRT-3DE)、体循环血流量(QsRT-3DE),采用TEE测量ASD面积(S),分析Qp/QsRT-3DE、Qp－QsRT-3DE与二维频谱多普勒法所测肺、体循环血流量之比(Qp/Qs2D)、之差(Qp－Qs2D)及S的相关性。结果 ①Qp/QsRT-3DE与Qp/Qs2D呈正相关(r=0.832,P<0.05),Qp－QsRT-3DE与Qp－Qs2D呈正相关(r=0.668,P<0.05)。②Qp/QsRT-3DE、Qp－QsRT-3DE、Qp/Qs2D、Qp－Qs2D与S呈正相关(r=0.873、0.861、0.801、0.822,P均<0.01)。结论 sRT-3DE能够快速、简单、准确地估测ASD的分流量。 |

| Objective To assess shunt volume in patients with atrial septal defect (ASD) by single cardiac cycle real- time three-dimensional echocardiography (sRT-3DE). Methods Thirty simple secundum ASD patients without middle or severe valvular regurgitation were enrolled. The sRT-3DE was used to obtain images of left and right ventricle. Left and right ventricular stroke volume (systemic, pulmonary blood flow QsRT-3DE, QpRT-3DE) were automatically measured with Va15a analytic software. The correlation among Qp/QsRT-3DE, Qp－QsRT-3DE and the area of the defect, the ratio of pulmonary flow to systemic blood flow (Qp/Qs2D) and their difference (Qp－Qs2D) measured by Doppler echocardiography were analyzed. Results ①Qp/QsRT-3DE was positively correlated with Qp/Qs2D (r=0.832, P<0.05), Qp－QsRT-3DE was positively correlated with Qp－Qs2D (r=0.668, P<0.05). ②Qp/QsRT-3DE, Qp－QsRT-3DE, Qp/Qs2D, Qp－Qs2D were positively correlated with the area of the defect (r=0.873, 0.861, 0.801, 0.822, all P<0.01). Conclusion sRT-3DE can easily and accurately estimate the shunt volume in patients with ASD. |
