A patient with primary pulmonary hypertension showed unusual echocardiographic findings. These included echoes arising from an intracavitary right ventricular muscle band mimicking a divided interventricular septum. The hemodynamic study excluded subvalvular right ventricular obstruction. Severe right ventricular hypertrophy was also present. Both findings were probably related and may possibly be found in similar cases with severe right ventricular hypertrophy, especially due to primary pulmonary hypertension. The right ventricular muscle band possibly represented hypertrophied moderator band.
一名原发性肺动脉高压患者表现出异常的超声心动图表现。这些表现包括源自心腔内右心室肌束的回声，类似室间隔分隔。血流动力学研究排除了瓣膜下右心室梗阻。同时还存在严重的右心室肥厚。这两种表现可能相关，并且在类似的严重右心室肥厚病例中，尤其是原发性肺动脉高压导致的病例中可能会发现。右心室肌束可能代表肥厚的节制索。
