Introduction: Ventricular arrhythmias (VA) are a common complication after left ventricular assist device (LVAD) implantation and contribute to increased mortality. The VT LVAD Score was created to help stratify patients into four risk categories: Low Risk, Moderate Risk, High Risk, and Very High Risk.Hypothesis: We sought to assess the performance of the VT LVAD score at our institution.Methods: Consecutive patients who underwent LVAD placement from 2015-2019 were reviewed. VT LVAD scores were correlated with VA free survival (VA-FS). Only 1 patient was in the low-risk group and was excluded from analysis.Results: A total of 237 patients who underwent LVAD implant (age 57.9 ± 14.6 years, 180 male, 89 ischemic cardiomyopathy, 102 with prior VAs, 102 Heartmate 3) were included. Of the 5 variables included in the VT LVAD score, only prior VA was associated VA-FS (HR 3.09[1.89-5.03], p<0.001 (Figure 1A), log rank p=0.003, Figure 1D). There was a significant difference in VA-FS between moderate versus both high and very high-risk groups (p=0.033 and p=0.029 respectively) as well as moderate vs high/very high-risk combined (p=0.041, Figure 1B). The significant difference in VA-FS between moderate vs high/very high-risk score groups persisted among all patients with prior VA (p=0.04, Fig 1C). No other between-group differences in VA-FS were seen (Figure 1B and 1C, p>0.05 for all).Conclusions: Patients with a VT LVAD score of high or very high-risk had worse survival free from VA than patients with moderate-risk score, no other between group differences were noted. History of VA is a simple and powerful risk factor for late VA post LVAD.
