Abstract | OBJECTIVES: METHODS: The institutional ventricular assist device database was searched for the period from March 2012 to March 2016. The primary end-point was the need for early (<7 days) surgical re-exploration due to persistent haemorrhage or cardiac tamponade postoperatively. The secondary clinical end-points were delayed chest closure, stroke, intracranial bleeding, re- thoracotomy >7 days and mortality up to 1 year. Unadjusted comparison was used for the entire groups. Because of non-random group assignment, propensity score matching was also performed to compare treatment effects. RESULTS: Twenty-one patients were treated with bivalirudin and 36 patients with heparin. INTERMACS levels were lower, inotropic score was higher and the prevalence of mechanical ventilation and preoperative ECLS implants was also significantly higher in the heparin group than in the bivalirudin group (P-values <0.05). The primary end-point was reached by 19% in the bivalirudin group and 16.7% in the heparin group ( bivalirudin group: odds ratio 1.18, 95% confidence interval 0.29-4.76; P = 0.820). The propensity score-matched groups also showed no difference in this regard (P = 0.455). All secondary clinical end-points were comparable between groups, both in the unadjusted analysis and in the propensity score-matched groups. CONCLUSIONS:
