对离体心脏和在体心脏进行了三维超声心动图对右心功能评价的研究.发观:三维超声心动图所测离体心室容量与实测值高度相关(r=0.92);对8例肺心病病人用三维超声心动图和单光子计算机断层仪测定RVEF.两者相关亦较好(r=0.86);对94名正常人,21 例肺心病人及5例房缺病人的研究发现,肺心病人的收缩末期容量增大,每搏输出量及右室射血分数降低.房缺病人的舒张末期容量、收缩末期容量,右室射血分数均降低(P<0.05).认为三维超声心动图是研究右心功能的可靠方法.

To assess the value of 3DE for measuring RV function We measured with 3DE in Porcine hearts and in patients. The results show that RV volume measured with 3DE in porcine hearts is nore closely to the real volume directly measured(r=0.92).Comparing the results of RVEF assessed by 3DE and that by SPECT, a correlation coefficient of 0.86 was found. The RV ESV of cor pulmonale was increased as compared with normals(P<0.001),while the mean RV SV and EF are decrcased. The RVESV, RVEDV,and RVEF of patients with atrial septum. Defects were increased as compared with normals(P<0.05).
