ABSTRACT

BACKGROUND: Left ventricular assist device (LVAD) recipients undergoing heart transplantation have increased bleeding risk. We compared conventional warfarin reversal with fresh frozen plasma vs 4-factor prothrombin complex concentrate (PCC) and the effect on transfusion requirements, blood bank costs, and clinical outcomes. METHODS: A retrospective review identified 60 consecutive LVAD recipients undergoing heart transplantation divided into two groups: 30 (no PCC) received fresh frozen plasma and 30 (PCC) received PCC. Patient characteristics, intraoperative and postoperative transfusion requirements, short-term clinical outcomes, and blood bank costs were compared. PCC association with transfusion requirements was assessed by multivariate linear regression. RESULTS: Patients who received PCC were younger (50 ± 11 vs 57 ± 13 years, p = 0.02), fewer had ischemic cardiomyopathy (23% vs 60%, p = 0.01), had more than one prior sternotomy (7% vs 30%, p = 0.04), and had higher preoperative hemoglobin (11.8 ± 1.8 vs 10.4 ± 1.8 g/dL, p = 0.01). The PCC group had a significantly shorter bypass time (185 vs 217 minutes, p = 0.01), received less fresh frozen plasma (2 vs 5 units, p = 0.03), cryoprecipitate (0 vs 2 units, p = 0.05), and total blood products (9 vs 13.5 units, p = 0.03) intraoperatively, and was less likely to require delayed sternal closure (3% vs 23%, p = 0.05). On multivariate linear regression, PCC was significantly associated with decreased intraoperative transfusion (ß = -6.09, p = 0.02). There was no difference in thromboembolic events or in-hospital death. Total blood bank costs were $4,949 for PCC and $3,677 for no PCC (p = 0.01). CONCLUSIONS: Although more costly, PCC reduced transfusion requirements and delayed sternal closure in heart transplant recipients bridged with LVAD, justifying its use over traditional warfarin reversal.
