PROTHROMBIN COMPLEX CONCENTRATE FOR RAPID REVERSAL OF WARFARIN-INDUCED ANTICOAGULATION AND INTRACEREBRAL HEMORRHAGE IN PATIENTS SUPPORTED BY A LEFT VENTRICULAR ASSIST DEVICE

Background: Intracerebral hemorrhage (ICH) is one of the most serious complications in patients supported by a left ventricular assist device (LVAD). We evaluate the efficacy of prothrombin complex concentrate (PCC) for rapid reversal of warfarin-induced anticoagulation in this population. Methods: A total of 38 consecutive ICH events in patients supported by an LVAD between 1996 and 2007 were retrospectively reviewed. Fourteen ICH events were treated with fresh frozen plasma (FFP) (Group FFP) and 24 ICH events were treated with PCC (Group PCC). The efficacy and outcome of PCC administration versus FFP were evaluated. Results: The proportion of patients surviving after an ICH event was significantly smaller in Group FFP than Group PCC (35.7% vs. 75.0%, p<0.05). None of the patients in Group FFP were able to undergo heart transplantation, whereas 21.4% patients in Group PCC successfully underwent heart transplantation. Conclusion: Patients on LVAD are in need for intensified anticoagulation and are at high risk of ICH; therefore, adequate use of PCC in the event of ICH could be of importance for survival and allow subsequent heart transplantation.
