Three patients with aortic valve endocarditis were studied. The single beam M-mode echocardiographic findings comprised the appearance in diastole of a cluster of shaggy echoes at the aortic valve in all three patients. Mitral flutter was seen in two patients and premature closure of the mitral valve in one patient. At multiple beam two-dimensional echocardiography, the echo cluster could in all three patients be seen to move perpendicular to the sound beams, ascending into the aorta in systole and descending in diastole. At valve replacement, vegetations were found that explained the abnormal echo cluster. The multiple beam echocardiography facilitated the interpretation of the single beam findings and increased the confidence therein. By applying the non-invasive modality of echocardiography in these patients with their high risk of embolism, cardiac catheterization may possibly be avoided.
对3例主动脉瓣心内膜炎患者进行了研究。单束M型超声心动图检查结果显示，所有3例患者在舒张期主动脉瓣处均出现一束粗糙回声。2例患者出现二尖瓣扑动，1例患者出现二尖瓣过早关闭。在多束二维超声心动图检查中，所有3例患者的回声束均可见垂直于声束移动，在收缩期升入主动脉，在舒张期下降。在瓣膜置换时，发现了赘生物，解释了异常回声束的原因。多束超声心动图有助于解释单束检查结果并增加对此的信心。通过对这些有高栓塞风险的患者应用无创性超声心动图检查方法，有可能避免进行心导管检查。
