Paradoxical interventricular septal motion with right ventricular dilatation has been considered the hallmark of right ventricular volume overload. We report a 43-year-old woman with severe pulmonary hypertension due to pulmonary veno-occlusive disease who exhibited these echocardiographic abnormalities. Right ventricular volume overload was excluded by physical examination, echocardiography with saline contrast study and by cardiac catheterization, angiography, and shunt study. These echocardiographic findings are thus not pathognomonic of right ventricular volume overload and can be seen with pressure overload as well.
矛盾性室间隔运动伴右心室扩张一直被认为是右心室容量负荷过重的标志。我们报告一名43岁因肺静脉闭塞性疾病导致严重肺动脉高压的女性，其超声心动图表现出这些异常。通过体格检查、盐水造影超声心动图以及心导管检查、血管造影和分流研究排除了右心室容量负荷过重。因此，这些超声心动图表现并非右心室容量负荷过重所特有，在压力负荷过重时也可见到。
