Abstract
This study examined left-ventricular assist device (LVAD) patients with pre-LVAD ventricular arrhythmias (VAs) to determine the rate of recurrent post-LVAD VAs and the impact of pre-LVAD atrial fibrillation (AF) on recurrent post-LVAD VAs. Medical records of 195 consecutive LVAD patients were reviewed. Descriptive statistics were generated and Cox proportional hazard models were used to assess the association of clinical variables with the time to recurrent VA. Forty-seven percent of 195 CHF patients who received LVAD-manifested significant VAs prior to LVAD implant (82% Heartmate II, 14% HVAD, 4% other; median follow-up = 17months), 41% of whom manifested recurrent post-LVAD VAs. Pre-LVAD AF was associated with recurrent VAs (hazard ratio = 3.73; 95% CI 1.33, 10.48; p = 0.012). Recurrent VAs were associated with increased mortality (hazard ratio = 3.06; 95% CI 1.17, 7.98; p = 0.023). A history of AF is prevalent in over half of LVAD patients with recurrent VAs and is associated with time to recurrence of VA.
