Moriyama等人；肺动脉高压右心室3D对疾病状况的误解。尽管右心室形态复杂，但二维右心室斑点跟踪超声心动图的实用性已被报道。3然而，它也有一些不可避免的局限性，包括由于通平面现象（一种在心动周期中横切面移动的现象）导致的心肌跟踪不准确，或者只能在纵向上测量应变。此外，其评价仅限于部分右心室游离壁和间隔壁。RV的形状很复杂。因此，三维分析被认为有利于RV功能分析。然而，传统的3D RV分析使用心脏磁共振成像或4D RV- function
Moriyama et al; Right Ventricular 3D in Pulmonary Hypertension to misunderstanding of the disease condition. The utility of 2D RV speckle-tracking echocardiography has been reported despite the complex RV morphology. 3 However, it has some inevitable limitations, including inaccurate myocardial tracking because of the throughplane phenomenon (a phenomenon in which the crosssection shifts during the cardiac cycle) or availability of strain measurement only in the longitudinal direction. Moreover, its evaluation was limited within a part of the RV free wall and septal wall. The RV has a complicated shape. Thus, 3D analysis has been considered favorable for RV functional analysis. However, the conventional 3D RV analyses using cardiac magnetic resonance imaging or 4D RV-Function
