Preoperative Levosimendan therapy reduces postoperative right ventricular failure in patients undergoing left ventricular assist device implantation.

ABSTRACT:

Objectives

Perioperative mortality and complications still remain high after left ventricular assist device (LVAD) implantation, especially in highly compromised patient cohorts. Here, we evaluate the effects of preoperative Levosimendan therapy on peri- and postoperative outcomes after LVAD implantation.

Methods

We retrospectively analysed 224 consecutive patients with LVAD implantation for end-stage heart failure between November 2010 and December 2019 in our centre with regard to short- and longer-term mortality as well as incidence of postoperative right ventricular failure (RV-F). Out of these, 117 (52.2%) received preoperative i.v. Levosimendan therapy within 7 days before LVAD implantation (Levo group).

Results

In-hospital, 30-day and 5-year mortality was comparable (in-hospital mortality: 18.8% vs 23.4%, P = 0.40; 30-day mortality: 12.0% vs 14.0%, P = 0.65; Levo vs control group). However, in the multivariate analysis, preoperative Levosimendan therapy significantly reduced postoperative RV-F but increased postoperative vasoactive inotropic score ([RV-F: odds ratio 2.153, confidence interval 1.146-4.047, P = 0.017; vasoactive inotropic score 24 h post-surgery: odds ratio 1.023, confidence interval 1.008-1.038, P = 0.002). These results were further confirmed by 1:1 propensity score matching of 74 patients in each group. Especially in the subgroup of patients with normal preoperative RV function, the prevalence of postoperative RV-F was significantly lower in the Levo- group as compared to the control group (17.6% vs 31.1%, P = 0.03; respectively).

Conclusions

Preoperative Levosimendan therapy reduces the risk of postoperative RV-F, especially in patients with normal preoperative RV function without effects on mortality up to 5 years after LVAD implantation.

Project description:IntroductionAlthough anticoagulation therapy is mandated after implantation of a left ventricular assist device (LVAD), postoperative bleedings and reoperations occur relatively frequently and are associated with worse outcomes. We evaluated the use of a conservative postoperative anticoagulation protocol in patients implanted with a HeartMate 3 (HM3) LVAD.MethodsIn a single-centre retrospective analysis of postoperative outcomes after HM3 LVAD implantation, a standard (old) anticoagulation protocol (i.e. early, full-dose anticoagulation with low-molecular weight heparin and overlapping vitamin K antagonist) was compared with a new conservative anticoagulation protocol (i.e. slow initiation of vitamin K antagonists without overlapping heparin). Main outcomes were changes in international normalised ratio (INR), lactate dehydrogenase (LDH), bleeding and/or tamponade events requiring reoperation, length of stay and adverse events.ResultsIn total, 73 patients (48 in old vs 25 in new protocol group) were evaluated. Mean age was 56 years (standard deviation 13) and most patients (78%) were males. Changes in INR and LDH in the first 14 days were similar in both groups (p = 0.50 and p = 0.997 for interaction, respectively). Number of bleeding/tamponade events requiring reoperation was lower in the new than in the old protocol group (4% vs 33%, p = 0.005). Postoperative 30-day mortality was similar, and we observed no thromboembolic events. Median (25th-75th percentiles) total length of postoperative hospital stay (27 (25-41) vs 21 (19-27) days, p < 0.001) and length of intensive care unit stay (5 (2-9) vs 2 (2-5) days, p = 0.022) were significantly shorter in the new protocol group.ConclusionThese retrospective data suggest that conservative slow initiation of anticoagulation therapy after HM3 LVAD implantation is associated with less bleeding/tamponade events requiring reoperation, a similar safety profile and a shorter duration of stay than the currently advised standard anticoagulation protocol.
