Premature opening of the aortic valve in late diastole has been demonstrated by echocardiography in a patient with severe aortic regurgitation. Valve opening coincided with the end of the diastolic murmur and equalization of aortic and left ventricular diastolic pressures. Echocardiography of the aortic valve in severe aortic reflux may, therefore, provide valuable information about the underlying haemodynamic disturbance.
超声心动图已证实，在一名严重主动脉瓣反流患者中，舒张期末期主动脉瓣过早开放。瓣膜开放与舒张期杂音的结束以及主动脉和左心室舒张压的平衡同时发生。因此，严重主动脉反流时主动脉瓣的超声心动图检查可能会提供有关潜在血流动力学紊乱的有价值信息。
