SURGELLA: A Scoping Review of Impella‐Assisted Hemodynamic Support in High‐Risk Non‐Cardiac Surgery

Artificial Organs, EarlyView.
In selected patients with severe LV dysfunction, Impella‐supported non‐cardiac surgery may provide a temporary hemodynamic bridge to otherwise prohibitive procedures. Published evidence remains limited to a small number of highly selected cases, supporting technical feasibility rather than comparative benefit or generalizable safety.

Early Multicenter Outcomes of Dedicated Transcatheter Aortic Valve Replacement for Left Ventricular Assist Device‐Associated Pure Aortic Regurgitation

Artificial Organs, EarlyView.
LVAD‐associated aortic regurgitation impairs circulatory support, with limited surgical and off‐label options. In a multicenter registry (n = 30), the AR‐dedicated JenaValve Trilogy TAVR eliminated AR, achieving 96.7% (29/30) technical success and 93.3% (28/30) device success (VARC‐3), with 3.3% (1/30) 30‐day mortality.

Progress Toward a Portable Artificial Lung: A Systematic Review

Artificial Organs, EarlyView.
Eight portable respiratory assist devices were identified. The CE‐marked MobyBox and the FDA‐approved Breethe OXY‐1 system are in clinical use. Each device is substantially minimized to allow ambulation, but further work is required to address challenges related to anticoagulant management and safe mobilization. Created in BioRender.

Predicting Device‐Induced Platelet Damage in Assisted Circulation Using a New Biophysical Model and Experimental Validation

Artificial Organs, EarlyView.
Quantitative assessment of a newly proposed CFD‐based biophysical model for predicting device‐induced platelet damage by circulatory assist devices was performed. The new model preserved the relative trends observed previously with the power‐law formulation across a range of clinically relevant pump operating conditions, while demonstrating improved ...

IL-33/ST2 Pathway and Classical Cytokines in End-Stage Heart Failure Patients Submitted to Left Ventricular Assist Device Support: A Paradoxic Role for Inflammatory Mediators?

Mediators of Inflammation, 2013
Background. Inflammation is a critical process contributing to heart failure (HF). We hypothesized that IL-33/ST2 pathway, a new mechanism regulated during cardiac stress, may be involved in the functional worsening of end-stage HF patients, candidates ...

Prevention and Management of Driveline Infections in Ventricular Assist Device Patients: The DESTINE 2.0 Staging Proposal and Expert Recommendations

Artificial Organs, EarlyView.
DESTINE 2.0 decision flowchart: stage‐based assessment and management of driveline exit‐site disorders. The flowchart provides a simplified decision‐support tool for the stage‐based evaluation and management of driveline exit‐site disorders in LVAD patients, intended as a practical complement to the staging pyramid (Figre 2) and the detailed staging ...

Ventricular Tachycardia Ablation in Structural Heart Disease With LVEF > 35%: Clinical Outcomes and Recurrence Patterns

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background In patients with structural heart disease (SHD) and moderately impaired left ventricular ejection fraction (LVEF > 35%), data on outcomes after ventricular tachycardia (VT) ablation remain limited. This analysis focuses on VT recurrence after ablation in patients presenting with sustained VT and LVEF > 35% within a secondary ...

Association Between Sleep Quality and Oxidative Stress in Postoperative Cardiovascular Patients—A Pilot Study

Journal of Sleep Research, EarlyView.
In 15 postoperative cardiac surgery patients, venous reactive oxygen species (ROS) measured by electron spin resonance (ESR) over 48 h showed no consistent circadian pattern. Higher ROS was associated with lower subjective sleep efficiency and more nocturnal awakenings, but not with other sleep measures.

Impact of ICD Presence in Patients With Left Ventricular Assist Devices for End‐Stage Heart Failure

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background The prognostic relevance of implantable cardioverter defibrillator (ICD) in patients with end‐stage heart failure (HF) with left ventricular assist device (LVAD) remains controversial. Objectives To evaluate the prognostic impact of ongoing use of ICD and associated complications in HF‐patients with LVAD‐implantation.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.
