Nine patients with anatomically documented vegetations on one or more cusps of the aortic valve had echocardiograms in which abnormal echoes were associated with the aortic leaflet echoes. The motion of the abnormal echoes during systole correlated well with the anatomic location of vegetations: a vegetation on the right coronary cusp moved anteriorly with systole while a vegetation on the noncoronary cusp moved posteriorly during systole. Our data, although inconclusive, suggest that echoes from a vegetation on the left coronary cusp maintain a mid-aortic position throughout the cardiac cycle. The echocardiographic appearance of vegetations is not specific, but in the setting of septicemia, dense mobile echoes in the region of the aortic valve are strongly suggestive of vegetation. A normal echocardiographic appearance of the aortic valve does not exclude the possibility that vegetation is present, especially if the growth is less than 5 mm in size.
9例经解剖证实主动脉瓣一个或多个瓣叶有赘生物的患者进行了超声心动图检查，其中异常回声与主动脉瓣叶回声相关。收缩期异常回声的运动与赘生物的解剖位置密切相关：右冠状动脉瓣上的赘生物在收缩期向前移动，而非冠状动脉瓣上的赘生物在收缩期向后移动。我们的数据虽然尚无定论，但表明左冠状动脉瓣上赘生物的回声在整个心动周期中保持在主动脉中部位置。赘生物的超声心动图表现并不具有特异性，但在败血症情况下，主动脉瓣区域密集的可移动回声强烈提示赘生物的存在。主动脉瓣超声心动图表现正常并不能排除存在赘生物的可能性，特别是当赘生物大小小于5mm时。
