title: Hemodynamic stabilization of acute prosthetic valve thrombosis using percutaneous catheter manipulation.
abstract: 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.
