Triple Björk-Shiley valve: More than 30 years of asymptomatic functioning: To the memory of late academic Prof. Isidor Papo and the 45th anniversary of the first valve implantation in Yugoslavia [PDF]

open access: yes, 2010
Introduction. The Björk-Shiley Delrin (BSD) tilting disc heart valve was first clinically used in 1969. A triple BSD valve replacement has not been quite common, because of high postoperative risk and complications, but there have been several cases with

Trial‐Based Hemolysis Modeling to Investigate Operating Modes of Continuous‐Flow LVADs

open access: yesArtificial Organs, EarlyView.
This work presents a methodology for determining online‐capable hemolysis models for continuous‐flow LVADs, derived from in vitro trials. The models are based on fitting a modified power law and applying the Lagrangian approach. They assist clinicians in selecting treatment strategies that minimize hemolysis, as demonstrated with the Sputnik1 LVAD ...

In Vitro Calcification Evaluation of Polycarbonate Urethane—Impact of Production Processes

open access: yesArtificial Organs, EarlyView.
The study shows that hot pressing induces chemical changes in PCU, promoting calcification, while solution‐cast patches remain unaffected. ABSTRACT Background Heart valve diseases remain a leading cause of death in industrialized nations. Polycarbonate urethane (PCU) is a promising material for heart valve prostheses due to its biocompatibility and low

A case study of technology transfer: Rehabilitative engineering at Rancho Los Amigos Hospital [PDF]

open access: yes
The transfer of NASA technolgy to rehabilitative applications of artificial limbs is studied. Human factors engineering activities range from orthotic manipulators to tiny dc motors and transducers to detect and transmit voluntary control signals.

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

open access: yesArtificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.

Inflammatory Cytokines as Early Predictors of Weaning Failure From Extracorporeal Life Support

open access: yesArtificial Organs, EarlyView.
Levels of IL‐8 and IL‐6 and their dynamics are reliable early predictors of ECLS weaning failure. ABSTRACT Background Weaning from extracorporeal life support (ECLS) in patients with refractory shock still remains a complex decision. Despite considerable advances in ECLS management, reliable biomarkers to predict weaning success are still not available.

Antithrombotic therapy in patients with prosthetic heart valves

open access: yesRevista Cubana de Cardiología y Cirugía Cardiovascular, 2014
The thromboembolic events are still an important complication in patients with substitution of any of the heart valves in spite of the advances obtained in the design of prostheses.
