ABSTRACT
BACKGROUND:
In complex operations surgeon volume may impact outcomes. We sought to understand if individual surgeon volume affects left ventricular assist device (LVAD) outcomes.METHODS:
We reviewed primary LVAD implants at an experienced ventricular assist devices (VAD)/transplant center between 2013 and 2019. Cases were dichotomized into a high-volume group (surgeons averaging 11 or more LVAD cases per year), and a low-volume group (10 or less per year). Propensity score matching was performed. Survival to discharge, 1-year survival, and incidence of major adverse events were compared between the low- and high-volume groups. Predictors of survival were identified with multivariate analysis.RESULTS:
There were 315 patients who met inclusion criteria-45 in the low-volume group, 270 in the high-volume group. There was no difference in survival to hospital discharge between the low (91.9%) and high (83.3%) volume matched groups (p = .22). Survival at 1-year was also similar (85.4% vs. 80.6%, p = .55). There was no difference in the incidence of major adverse events between the groups. Predictors of mortality in the first year included age (hazards ratio [HR] 1.061, p < .001), prior sternotomy (HR 1.991, p = .01), increasing international normalized ratio (HR 4.748, p < .001), increasing AST (HR 1.001, p < .001), increasing bilirubin (HR 1.081, p = .01), and preoperative mechanical ventilation (HR 2.662, p = .005). Individual surgeon volume was not an independent predictor of discharge or 1-year survival.CONCLUSION:
There was no difference in survival or adverse events between high and low volume surgeons suggesting that, in an experienced multidisciplinary setting, low-volume VAD surgeons can achieve similar outcomes to their high-volume colleagues.Palavras-chave
