Echocardiographic features of acute aortic regurgitation resulting from bacterial endocarditis have been well documented (Nathan et al., 1980; Weaver et al., 1977; Wray, 1975a), and include thick shaggy echoes from aortic valve in diastole, fine diastolic flutter of aortic valves suggestive of rupture of cusps, and premature closure of mitral valves. Echocardiography being a sensitive noninvasive technique for detecting aortic valve vegetations is heavily relied on for earlier diagnosis and prompt therapy of these patients. Prognosis of echocardiographically positive endocarditis is known to be worse than for echo-negative patients. The following case is being presented because of an unusual echocardiographic manifestation with mid-diastolic aortic valve opening secondary to flail aortic valve from staphylococcal endocarditis of the aortic valve.
由细菌性心内膜炎导致的急性主动脉瓣反流的超声心动图特征已有充分记载（内森等人，1980年；韦弗等人，1977年；雷，1975年a），包括舒张期主动脉瓣上粗大杂乱的回声、提示瓣叶破裂的主动脉瓣舒张期细微扑动以及二尖瓣提前关闭。超声心动图作为一种检测主动脉瓣赘生物的敏感非侵入性技术，对于这些患者的早期诊断和及时治疗至关重要。已知超声心动图检查呈阳性的心内膜炎患者的预后比检查呈阴性的患者更差。之所以呈现以下病例，是因为该病例有不寻常的超声心动图表现，即由于主动脉瓣葡萄球菌性心内膜炎导致连枷样主动脉瓣，出现舒张中期主动脉瓣开放。
