ABSTRACT
BACKGROUND:
Continuous-flow left ventricular assist device (CF-LVAD) substantially improves survival in endstage heart failure patients. However, bleeding complications are common after CF-LVAD implantation and in some cases, re-exploration for bleeding is needed. We aimed to investigate the incidence, timing, and risk factors of bleeding requiring re-exploration after CF-LVAD implantation.MethodsâandâResults:
We retrospectively reviewed 162 consecutive patients (age 43±13 years, 71% men) who underwent CF-LVAD implantation (HeartMateII 119, Jarvik2000 15, HVAD 13, EVAHEART 10, DuraHeart 5) from January 2012 to June 2019. During follow-up [median 662 days, interquartile range (IQR) 364-1,116 days], 35 (21.6%) experienced re-exploration for bleeding. The median timing of re-exploration was 6 (IQR 1-10) days. In the multivariate logistic regression analysis, postoperative platelet count was an independent predictor for re-exploration for bleeding after CF-LVAD implantation (per 104/µL odds ratio 0.83, 95% confidence interval 0.74-0.93, P=0.002). Patients who experienced re-exploration for bleeding had a significantly worse survival rate than patients who did not (at 4 years, 73.6% vs. 90.1%, P=0.039).CONCLUSIONS:
Re-exploration for bleeding is prevalent after CF-LVAD implantation, especially in patients with low postoperative platelet counts. As bleeding requiring re-exploration is associated with poor prognosis, risk stratification using the postoperative platelet count may be beneficial for these patients.Palavras-chave
