Heart Device Carries High Risk of Thrombosis

HVAD, a device manufactured by HeartWare to assist the heart in those waiting for a heart transplant may increase the risk of thrombosis, the formation of life-threatening blood clots. Of the 250 patient who had the device implanted that totaled 174 years, 16 developed clots which is a 9.2 percent risk. Although smaller and quicker to put in than its competitor the HeartMate II, concerns about blood clots have had a negative impact. Aurora St. Luke’s Medical Center in Milwaukee, WI has not implanted a device since a patient was treated for a clot that stopped it from working. HeartWare is changing its product in hopes of reducing thrombosis and some doctors feel that drug management may be a factor in what most cardiac experts acknowledge is a high rate of thrombosis.
