An occluder which intermittently became stuck in the open position with concomitant aortic regurgitation was encountered in a patient subjected to an aortic valve replacement with a 23 Omniscience prosthetic valve. The patient was intermittently aware of the complete momentary disappearances of the valve sounds, the etiology of which could not be discerned. During fluoroscopic examination, the occluder became stuck for a few cardiac cycles in what appeared to be the fully open position before finally moving. Prosthetic valve malfunction was thus diagnosed. The emergency operation was successful. Operative findings revealed that a thin thrombus had developed in a curtain-like fashion on the left ventricular face of the prosthesis with mild tissue overgrowth along the perimeter of the valve. The Omniscience prosthesis was replaced with a 19-mm St. Jude Medical prosthesis, and the patient's postoperative course has been uneventful.
在一名接受23号Omniscience人工心脏瓣膜主动脉瓣置换术的患者中，发现一个封堵器间歇性地卡在开放位置，并伴有主动脉瓣反流。患者间歇性地感觉到瓣膜声音完全瞬间消失，但其病因无法查明。在荧光透视检查期间，封堵器在似乎完全打开的位置卡住了几个心动周期，最终才移动。由此诊断为人工心脏瓣膜故障。急诊手术成功。手术结果显示，在假体的左心室表面形成了一层薄血栓，呈帘状，瓣膜周边有轻度组织过度生长。将Omniscience假体换成了19毫米的圣犹达医疗假体，患者术后恢复顺利。
