Echocardiography provided excellent insight into the altered hemodynamics in a patient with acute, severe aortic regurgitation due to bacterial endocarditis. The most notable echographic findings were premature closure of the mitral valve and diastolic opening of the aortic valve. At surgery, the patient proved to have a large perforation in the base of the noncoronary cusp.
超声心动图能很好地洞察因细菌性心内膜炎导致急性重度主动脉瓣反流患者血流动力学的改变。最显著的超声心动图表现是二尖瓣提前关闭和主动脉瓣舒张期开放。手术时发现，该患者无冠瓣基部有一个大穿孔。
