Background:Although intra-aortic balloon pump (IABP) is sometimes used before cardiac surgery to achieve better outcome in high-risk patients, the clinical impact of prophylactic IABP support before left ventricular assist device (LVAD) implantation in patients with worsening hemodynamics was unknown.Methods and Results:We enrolled 22 patients with worsening hemodynamics who had received IABP support before LVAD (IABP group), and also enrolled 22 patients receiving neither IABP nor extracorporeal membrane oxygenation before LVAD, who were selected on propensity score matching (non-IABP group). Although both groups had similar preoperative background, the IABP group had shorter postoperative intensive care unit (ICU) stay, and more improved hemodynamics (P<0.05 for all). Serum total bilirubin and creatinine decreased significantly in the IABP group compared with the non-IABP group during 1 month after LVAD implantation (P<0.05 for both). Medical expenses during perioperative ICU stay were significantly lower in the IABP group compared with the non-IABP group, even including the cost of preoperative IABP support (P<0.05).Conclusions:Prophylactic IABP support in heart failure patients with worsening hemodynamics improves post-LVAD clinical course and reduces perioperative medical expenses.
