Thrombotic obstruction of bileaflet valves: surgical management and fiberoptic thrombectomy.
Three patients underwent emergency operation for thrombotic obstruction of a bileaflet mechanical prosthesis (two St. Jude and one Duromedics) in the mitral position. The three valves were successfully thromboectomized with return to normal function. In 2 patients removal of the thrombus at the valve hinges was assisted by the use of a flexible fiberoptic choledochoscope. All 3 patients remain well 2 years after the procedure, maintained on a regimen of warfarin and dipyridamole.
