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

Artificial Organs, Volume 50, Issue 8, Page 1125-1135, August 2026.
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 ...

Stopping LVAD Bleeding [PDF]

Circulation Research, 2017
Left ventricular assist devices (LVADs) are efficient pumps that assist the circulation. They are rapidly evolving and being inserted into an increasing number of patients with advanced heart failure either as a bridge to transplantation or increasingly as destination therapy.

How Formal and Informal Nurse Leaders Enact Shared Implementation Leadership in a Hospital Setting

Journal of Advanced Nursing, Volume 82, Issue 8, Page 7987-8005, August 2026.
ABSTRACT Aim To describe how implementation leadership manifests among formal and informal point of care nurse leaders during a successful evidence‐based practice implementation. Design A collective case study. Methods A conceptual framework on shared implementation leadership guided the study. Two units known for strong implementation were selected as

The interplay between pulsatility, sympathetic regulation and renal physiology: Implications for left ventricular assist devices

Experimental Physiology, Volume 111, Issue 8, Page 3514-3524, 1 August 2026.
Abstract Left ventricular assist devices have gained traction both as a bridge therapy and as a destination therapy in the management of heart failure. Many of these devices reinstate blood flow in a continuous manner as opposed to the pulsatile flow present in normal physiology.

The approach to placement of a continuous-flow intracorporeal ventricular assist device in small left ventricle

JHLT Open
Background: The HeartMate 3 (HM3) has become among the most widely utilized durable left ventricular (LV) assist devices (LVAD) owing to reduced rates of pump thrombosis, bleeding, and stroke.
