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.

Frank-starling control of a left ventricular assist device

, 2011
A physiological control system was developed for a rotary left ventricular assist device (LVAD) in which the target pump flow rate (LVADQ) was set as a function of left atrial pressure (LAP), mimicking the Frank-Starling mechanism.

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 ...

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

Journal of Advanced Nursing, EarlyView.
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 Effect of Left Ventricular Assist Devices (LVAD) on Pulmonary Hypertension in End-Stage Heart Failure.

, 2021
Despite the increasing prevalence of advanced heart failure, transplantation rates have remained stable in Canada due to limited organ availability. Consequently, the number of implanted left ventricular assist devices (LVAD) and average time on device ...

Anticoagulation Monitoring in Left Ventricular Assist Device (LVAD) Patients

The VAD Journal, 2017
The use of left ventricular assist devices (LVAD) provides a treatment strategy for advanced heart failure patients to prolong life and serve as a mediator (bridge to transplant) until an organ becomes available in patients considered suitable candidates for heart transplantation.

Patients Experiencing Unsuccessful Defibrillation From Implantable Cardiac Devices Remain at Elevated Risk Despite Procedural Management

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Unsuccessful defibrillation therapy in patients with implantable cardiac defibrillators (ICDs) and ventricular tachytherapies may occur due to patient and/or device‐related factors; appropriate management strategies after failed defibrillation therapy have been incompletely described.
