背景：开发了一种新型的全自动右心室（RV）软件，用于RV体积和功能的三维定量。软件性能与心脏磁共振（CMR）的直接比较有限。因此，本研究的目的是测试全自动RV定量软件的可行性、准确性和再现性，以CMR成像作为参考。方法：共纳入170例同时进行CMR和三维超声心动图检查的患者。使用全自动三维RV定量软件获得RV舒张末期容积（RVEDV）、RV收缩末期容积（RVESV）和RV射血分数（RVEF），并与CMR参考进行比较。对于技术间一致性，使用斯皮尔曼相关性和Bland-Altman分析。结果：全自动RV定量软件在149例患者中是可行的。与CMR值相比，RVEDV和RVESV被低估，RVEF被高估。通过手动编辑方法获得的RV测量值与CMR值的相关性优于未经手动编辑的RV测量值（RVEDV，0.924 vs. 0.794; RVESV，0.955 vs. 0.854; RVEF，0.941 vs. 0.781，均p < 0.0001），偏倚更小，一致性限（LOA）更窄。在RV功能严重受损或低帧速率的患者中，使用自动软件（无手动编辑和有手动编辑）测量RV容积和EF的偏差和LOA大于RV功能正常和轻度受损或高帧速率的患者。全自动RV三维测量具有高度可重复性。结论：新的全自动RV软件显示出良好的可行性和重现性，测量值与CMR值有很高的相关性。这些发现支持新型3D自动RV软件在临床实践中的常规应用。
Background: A novel, fully automated right ventricular (RV) software for three-dimensional quantification of RV volumes and function was developed. The direct comparison of the software performance with cardiac magnetic resonance (CMR) was limited. Therefore, the aim of this study was to test the feasibility, accuracy, and reproducibility of a fully automated RV quantification software against CMR imaging as a reference. Methods: A total of 170 patients who underwent both CMR and three-dimensional echocardiography were enrolled. RV end-diastolic volume (RVEDV), RV end-systolic volume (RVESV), and RV ejection fraction (RVEF) were obtained using fully automated three-dimensional RV quantification software and compared with a CMR reference. For inter-technical agreement, Spearman correlation and Bland–Altman analysis were used. Results: The fully automated RV quantification software was feasible in 149 patients. RVEDV and RVESV were underestimated, and RVEF was overestimated compared with CMR values. RV measurements obtained from the manual editing method correlated better with CMR values than that without manual editing (RVEDV, 0.924 vs. 0.794: RVESV, 0.955 vs. 0.854; RVEF, 0.941 vs. 0.781 respectively, all p < 0.0001) with less bias and narrower limit of agreement (LOA). The bias and LOA for RV volumes and EF using the automated software without and with manual editing were greater in patients with severely impaired RV function or low frame rate than those with normal and mild impaired RV function, or high frame rate. The fully automated RV three-dimensional measurements were highly reproducible. Conclusion: The novel fully automated RV software shows good feasibility and reproducibility, and the measurements had a high correlation with CMR values. These findings support the routine application of the novel 3D automated RV software in clinical practice.
