The Impact of Preoperative Right Ventricular Dysfunction and Ventricular Arrhythmias on Left Ventricular Assist Device Outcomes.

Ventricular arrhythmias (VA) are common in patients being evaluated for left ventricular assist devices (LVADs) but the impact of comorbid right ventricular dysfunction (RVD) on outcomes after LVAD is not known. We performed a single-center, retrospective cohort study of patients undergoing LVAD implantation from 2005 to 2021. Patients were stratified by VA history before LVAD into no VA, low burden VA (LBVA), or clinically significant VA (CSVA) groups.
