Thrombosis of a tilting-disk prosthetic heart valve can be an acute and potentially life-threatening problem. Surgical thrombectomy, valve replacement, or systemic thrombolytic agents have been successfully employed in the management of such cases. Some patients, however, may not survive the acute episode long enough to receive definitive surgical therapy. For such patients, temporary hemodynamic stabilization might be achieved by re-establishing partial valve disk mobility. This report describes a technique for re-establishing valve disk mobility in an acutely compromised patient by using a percutaneously introduced "rigid" catheter to manipulate an entrapped tilting-disk valve in the aortic position.
倾斜盘式人工心脏瓣膜血栓形成可能是一个急性且潜在危及生命的问题。手术取栓、瓣膜置换或全身溶栓药物已成功用于此类病例的治疗。然而，一些患者可能无法在急性发作中存活足够长的时间以接受确定性手术治疗。对于此类患者，通过重新建立部分瓣膜盘的活动度或许可以实现临时血流动力学稳定。本报告描述了一种通过经皮插入“刚性”导管来操纵主动脉位置的卡瓣倾斜盘式瓣膜，从而在急性病情严重的患者中重新建立瓣膜盘活动度的技术。
