Echocardiographic studies provide information useful in determining the etiology and location of aortic valvular lesions, but assessment of their severity remains difficult. We report the findings in two patients with surgically confirmed right (case 1) and noncoronary (case 2) flail aortic leaflets in whom dense echoes filled the aortic root in systole, only to move from this position into the left ventricular outflow tract during diastole. This echocardiographic finding is a clinically useful noninvasive indicator of rupture of the right or noncoronary aortic cusp and dictates a need for early surgery.
超声心动图研究为确定主动脉瓣病变的病因和部位提供了有用信息，但评估其严重程度仍然困难。我们报告了两名经手术证实分别为右冠瓣（病例1）和无冠瓣（病例2）连枷样主动脉瓣叶的患者的检查结果，这两名患者在收缩期主动脉根部充满密集回声，而在舒张期这些回声仅从该位置移动到左心室流出道。这种超声心动图表现是右冠瓣或无冠瓣破裂的一种临床上有用的非侵入性指标，提示需要早期手术。
