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 = 17 months), 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.

Background: Better risk stratification is needed to evaluate patients with non-ischemic cardiomyopathy (NICM) for prophylactic implantable cardioverter-defibrillators (ICD). Growing evidence suggests cardiac magnetic resonance imaging (CMR) may be useful in this regard.
Objective: We aimed to determine if late-gadolinium enhancement (LGE) seen on CMR (dichotomized as none/minimal <2% vs significant ≥2%) predicts appropriate ICD therapies (primary endpoint) and/or all-cause mortality/transplant/left-ventricular assist device (LVAD) implantation (secondary endpoint) in NICM patients.

Background: Left Ventricular Assist Device (LVAD) implantation is an important treatment option for patients with advanced CHF. Referral to an early, intensive cardiac rehabilitation (CR) program in these patients seems still underused. This observational descriptive study aimed to evaluate the feasibility and efficacy of an early intensive CR program in LVAD recipients, also comparing results with a matched group of advanced HFrEF patients.

Heart failure (HF) remains a significant public health issue, with heart transplantation (HT) being the gold standard treatment for end-stage HF. The increasing use of mechanical circulatory support, particularly left ventricular assist devices (LVADs), as a bridge to transplant (BTT), presents new perspectives for increasingly complex clinical scenarios. This study aimed to compare long-term clinical outcomes in patients in heart failure with reduced ejection fraction (HFrEF) receiving an LVAD as BTT to those undergoing direct-to-transplant (DTT) without mechanical support, focusing on survival and post-transplant complications.

The HeartMate 3 (HM3, Abbott) left ventricular assist device (LVAD) is the only commercially available option considered suitable for long-term circulatory support. External compression of the outflow graft causing obstruction (eOGO) is a serious adverse event affecting patients on long-term support. The obstruction occurs due to the accumulation of gelatinous substance between the bend relief and outflow graft.

Despite the high progress that has been made in the field of cardiology, the left ventricular assist device (LVAD) can still cause complications (thrombosis/bleeding) in heart failure (HF) patients after implantation. Complications develop due to the incorrect dose of antithrombotic therapy, due to the influence of the non-physiological shear stress of the device, and also due to inherited genetic polymorphisms. Therefore, the aim of our study is to identify the influence of the genetic polymorphisms on complication development in HF patients with implanted LVADs with prescribed antiplatelet therapy.
