Comparison of a Miniaturized Implantable Two‐Stage Rotodynamic Blood Pump to Equivalent Single‐Stage Concepts

Artificial Organs, EarlyView.
This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

Identification of Coagulation Phenotypes Using Viscoelastic and Conventional Assays During Veno‐Venous Extracorporeal Membrane Oxygenation: A Hierarchical Clustering Analysis

Artificial Organs, EarlyView.
Hierarchical clustering of viscoelastic and conventional coagulation parameters identified three distinct phenotypes in V‐V ECMO patients, revealing substantial APTT–CK‐R discordance and highlighting the value of TEG‐derived markers for detecting coagulopathy not captured by standard monitoring.

Device‐Induced Blood Damage in Pump‐Assisted Circulation: A Comparative Study of HeartMate III and BrioVAD Pumps

Artificial Organs, EarlyView.
Shear‐induced blood damage—including hemolysis, platelet and neutrophil injury, and von Willebrand factor (vWF) degradation—was evaluated for the BrioVAD and HM3 using an in vitro circulatory loop under clinically relevant conditions. Across 15 biomarkers (n > 6 per group), no significant differences were observed between the two devices.

The Role of Patients' Treatment Expectations in Ventricular Assist Device Support: Results From a Convergent Mixed Methods Study

Artificial Organs, EarlyView.
This mixed methods study aimed to: (i) identify treatment expectations held by individuals with a ventricular assist device (VAD), (ii) assess the extent to which these expectations have been met, and (iii) examine how treatment expectations relate to VAD‐specific health‐related quality of life (HRQoL) ABSTRACT Objectives Treatment expectations ...
