Mechanical Tricuspid Valve Thrombosis Successfully Treated With Tissue Plasminogen Activator.

Prosthetic mechanical valve thrombosis has traditionally been managed with urgent surgical intervention. However, the risk of redo sternotomy can be prohibitively high in some patients. Thrombolytic therapy as a noninvasive treatment of mechanical valve thrombosis is a well-recognized alternative, but optimal dosing and patient selection remain incompletely characterized for right-side mechanical valves.
