Background: Recurrent ventricular tachyarrhythmias (VTA) are “A factor” modifiers in the Interagency Registry for Mechanically Assisted Circulatory Support profile. The effect of recurrent VTA on clinical outcome, however, is controversial. We evaluated the impact of recurrent VTA on outcome in Japanese heart transplant candidates with a left ventricular assist device (LVAD). Methods and Results: Sixty-six adult patients with advanced heart failure who were listed for heart transplantation between January 2005 and October 2017 were enrolled in the study. Recurrent VTA (modifier A status) was defined as a sustained ventricular tachycardia or fibrillation that required implantable cardioverter defibrillator shocks or an external defibrillator more than twice weekly. The primary outcome was death from any cause. The secondary outcomes were the first occurrence of VTA and recurrent VTA after LVAD implantation. Sixteen patients (24%) met the criteria for modifier A status, and 15 patients had an LVAD implanted. During a median follow-up of 1,124 days, 21 of 60 patients with an LVAD died. There was a significantly higher mortality rate in LVAD patients with modifier A status than in those who did not meet the modifier A criteria. On multivariate analysis, patients with modifier A status had an increased risk of mortality (HR, 3.43; 95% CI: 1.30–8.61, P=0.001). Conclusions: Recurrent VTA might be a marker for worse outcome in Japanese heart transplant candidates with an LVAD.

Background:Hemocompatibility-related adverse events (HRAEs) are substantial issues in patients with left ventricular assist devices (LVADs). Atrial fibrillation (AF) is associated with worse prognosis in patients with heart failure (HF), but its effect on HRAEs following LVAD implantation remain uncertain.Methods and Results:Data from the Japanese Mechanically Assisted Circulatory Support registry of consecutive patients who received HeartMate II LVADs and were followed for 1 year were retrospectively reviewed. Among 190 patients, 23 had AF and 167 had sinus rhythm. The AF group had comparable baseline characteristics with the non-AF group except for their higher age (53 vs. 42 years, P<0.001). Following LVAD implantation, most cases of AF (73%) persisted. Antiplatelet therapy, anticoagulation therapy, and LVAD speed following LVAD implantation were comparable between groups (P>0.05 for all). The 1-year survival free from HRAEs was comparable between groups (83% vs. 76%, P=0.52). Event rates of the breakdown of HRAEs were comparable between groups except for a relatively higher rate of surgically managed pump thrombosis in the AF group (0.16 vs. 0.04, incidence rate ratio 3.75, 95% confidence interval 0.87–16.1, P=0.075). These trends still remained with propensity score-matched comparison.Conclusions:Existence of AF had no effect on the development of HRAEs following LVAD implantation. The need to aggressively treat AF before or after LVAD implantation needs further investigation.
