An abnormal diastolic indentation of the mitral valve has been noted on short-axis two-dimensional echocardiograms in patients with aortic insufficiency. In order to assess the clinical usefulness of this finding, we reviewed the echocardiograms of 18 patients with this lesion who had undergone cineaortography. Results were compared with those of a control group of 100 patients. Initial diastolic indentation of the anterior mitral leaflet occurred in 8 of 12 patients with 3+ to 4+ aortic insufficiency. None of the patients with lesser regurgitation and no patients from the control group demonstrated this pattern. The presence of this abnormality appears to be a specific indicator of critical aortic insufficiency.
在主动脉瓣关闭不全患者的短轴二维超声心动图上，已观察到二尖瓣舒张期异常压迹。为了评估这一发现的临床实用性，我们回顾了18例患有该病变且已接受主动脉造影的患者的超声心动图。结果与100例对照组患者的结果进行了比较。在12例主动脉瓣反流为3+至4+的患者中，有8例出现二尖瓣前叶初始舒张期压迹。反流较轻的患者以及对照组患者均未出现这种模式。这种异常的存在似乎是严重主动脉瓣关闭不全的一个特异性指标。
