To estimate the severity of right ventricular hypertension noninvasively, the two-dimensional echocardiograms of 86 patients were examined--26 patients with atrial septal defect (ASD group), 22 with rheumatic valvular heart disease (VHD group), 12 with primary pulmonary hypertension (PPH group) and 26 with tetralogy of Fallot (Fallot group)--and data were compared with those of 20 normal persons. The interventricular septal (IVS) curvature index (delta r) from short axis view correlated well with the ratio of right to left ventricular systolic pressure (RVP/LVP). When IVS became convex towards the right ventricular cavity, the correlative coefficient between delta r and RVP/LVP was r = 0.75 in the ASD group, r = 0.83 in the VHD group, r = 0.71 in the PPH group and r = 0.77 in the Fallot group. The RVP/LVP approached a plateau when IVS became straight or convex towards the left ventricular cavity. Two-dimensional echocardiography provides a useful means to assess the right ventricular systolic pressure non-invasively.
为了无创评估右心室高压的严重程度，对86例患者的二维超声心动图进行了检查，其中26例患有房间隔缺损（ASD组），22例患有风湿性瓣膜性心脏病（VHD组），12例患有原发性肺动脉高压（PPH组），26例患有法洛四联症（法洛组），并将数据与20名正常人的数据进行了比较。短轴视图的室间隔（IVS）曲率指数（δr）与右心室与左心室收缩压之比（RVP/LVP）密切相关。当IVS向右心室腔凸出时，ASD组中δr与RVP/LVP之间的相关系数为r = 0.75，VHD组中为r = 0.83，PPH组中为r = 0.71，法洛组中为r = 0.77。当IVS变直或向左心室腔凸出时，RVP/LVP接近平台期。二维超声心动图提供了一种无创评估右心室收缩压的有用方法。
