A Study Comparing a New Dosing Regimen of Clot-dissolving Drug for Mechanical Heart Valves Which Show Clots

Summary

The optimal dosage and duration of administration of clot-dissolving medications for the treatment of patients with mechanical heart valves with clots is not known. We hypothesized that a large dose of the clot-dissolving medicine given initially (akin to the dose given in the treatment of heart attacks), might speed up the dissolution of the clot and rapidly restore the functioning of the mechanical heart valve.
