High-frequency diastolic oscillation of the anterior mitral leaflet is a common echocardiographic feature in aortic regurgitation. We have studied a group of 56 patients with aortic regurgitation in whom oscillation of the anterior mitral leaflet was present. Thirty-one of these had similar diastolic oscillation of the posterior leaflet; occasional patients demonstrated oscillation of the interventricular septum or chordae tendineae. The presence of these diastolic oscillations did not correlate with the presence of the Austin-Flint murmur. We conclude that diastolic oscillation of left ventricular structures other than the anterior mitral leaflet can be recorded on echocardiograms of patients with aortic regurgiationmthe mechanism responsible for these oscillations is not known; several possibilities are discussed.
二尖瓣前叶高频舒张期振荡是主动脉瓣反流常见的超声心动图特征。我们研究了一组56例存在二尖瓣前叶振荡的主动脉瓣反流患者。其中31例后叶有类似的舒张期振荡；偶尔有患者表现出室间隔或腱索振荡。这些舒张期振荡的存在与奥斯汀·弗林特杂音的存在无关。我们得出结论，在主动脉瓣反流患者的超声心动图上可以记录到二尖瓣前叶以外的左心室结构的舒张期振荡；这些振荡的机制尚不清楚；文中讨论了几种可能性。
