In Vivo Biocompatibility of an Innovative Elastomer for Heart Assist Devices. [PDF]

Polymers (Basel), 2022
Cardiac surgical approaches require the development of new materials regardless of the polyurethanes used for pulsatile blood pumps; therefore, an innovative biomaterial, a copolymer of poly(ethylene terephthalate) and dimer fatty acid (dilinoleic acid) modified with D-glucitol, hereafter referred to as PET/DLA, has been developed, showing non ...

A monitoring device for pressurised-air-driven diaphragm-based artificial heart assist devices [PDF]

Clinical Physics and Physiological Measurement, 1992
A non-invasive device has been developed to monitor the diaphragm position and the blood flow in artificial heart assist devices equipped with a pressurised-air-driven diaphragm. Light scattering from the diaphragm is used as a mechanism for measuring. Information about the position of several points of the diaphragm can be obtained.

In-Vitro Biocompatibility and Hemocompatibility Study of New PET Copolyesters Intended for Heart Assist Devices. [PDF]

Polymers (Basel), 2020
(1) Background: The evaluation of ventricular assist devices requires the usage of biocompatible and chemically stable materials. The commonly used polyurethanes are characterized by versatile properties making them well suited for heart prostheses applications, but simultaneously they show low stability in biological environments.

Synergistic Model of Cardiac Function with a Heart Assist Device [PDF]

Bioengineering, 2019
The breakdown of cardiac self-organization leads to heart diseases and failure, the number one cause of death worldwide. The left ventricular pressure–volume relation plays a key role in the diagnosis and treatment of heart diseases. Lumped-parameter models combined with pressure–volume loop analysis are very effective in simulating clinical scenarios ...

Platelet Activation Markers in Patients With Heart Assist Device [PDF]

Artificial Organs, 2005
Abstract:  Clinical use of heart assist devices is often associated with thromboembolic complications. We hypothesized that platelets may be activated in patients receiving assist devices and examined expression of the platelet activation markers CD62, CD63, and thrombospondin using flow cytometry in eight patients with Novacor left ventricular assist ...

Risk Factors for Development of Stroke in Patients With Continuous-Flow Left Ventricular Assist Device Support as Destination Therapy [PDF]

Texas Heart Institute Journal
Background: Continuous-flow left ventricular assist devices (LVADs) are increasingly used as destination therapy. Although postimplantation stroke rates have been described in the context of bridge-to-transplant or mixed cohorts, stroke development is ...

Incidence of malignancies after lung transplantation and their effect on the outcome. 26 years' experience

Heliyon, 2023
Background: Malignancy is a significant, life-limiting complication after lung transplantation (LuTx) and the second common long-term cause of death. We aimed to investigate its incidence and effect on the outcome.
