In Vitro Calcification of Bioprosthetic Heart Valves: Method Validation by Comparative Heart Valve Calcification Testing

open access: yesArtificial Organs, EarlyView.
We have developed a unique method for pre‐clinical heart valve prostheses evaluation of calcification propensity. Results from the test can directly be translated into improvements of prostheses design, materials, and anti‐calcification treatments, and therefore have a significant impact on heart valve prostheses quality and patient care in the future.

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 ...

Repositionable Versus Balloon-Expandable Devices for Transcatheter Aortic Valve Implantation in Patients With Aortic Stenosis. [PDF]

open access: yes, 2016
The safety and effectiveness of the fully repositionable LOTUS valve system as compared with the balloon-expandable Edwards SAPIEN 3 prosthesis for the treatment of aortic stenosis has not been evaluated to date.

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

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.

Hemocompatibility Outcomes After Aspirin Withdrawal in Long‐Term HeartMate 3 Left Ventricular Assist Device Patients on Vitamin K Antagonists

open access: yesArtificial Organs, EarlyView.
Aspirin discontinuation in long‐term, stable Heart Mate 3 LVAD patients maintained on Vitamin K antagonists did not increase hemocompatibility‐related adverse events. These findings support the safety of simplified antithrombotic therapy and extend randomized evidence for aspirin avoidance to the long‐term management of Heart Mate 3 recipients ...

Mechanical valve dysfunction in Yemen

open access: yesHeart Views, 2010
Background: Rheumatic heart disease is the most common cardiac disease in Yemen. It is associated with high morbidity and mortality. Valve replacement is the most common open heart surgery procedure in our cardiac center.

Percutaneous Versus Surgical Cannulation for Femoro‐Femoral Venoarterial Extracorporeal Membrane Oxygenation: A Retrospective Cohort Study on Cannulation‐Related Complications

open access: yesArtificial Organs, EarlyView.
Percutaneous femoro‐femoral V‐A ECMO cannulation was associated with more than a two‐fold lower risk of site bleeding and nearly a six‐fold lower risk of infection compared with surgical cut‐down, with no difference in limb ischemia. Absence of distal perfusion catheterization and larger arterial cannula size were additional modifiable ischemia risk ...

Hemocompatibility and Long‐Term Outcomes in HeartWare Versus HeartMate II Versus HeartMate 3: Multicenter Real‐World Cohort

open access: yesArtificial Organs, EarlyView.
Multicenter real‐world cohort (n = 327) comparing LVADs: HeartMate 3 (HM3), HeartMate II (HMII), and HeartWare (HVAD). HM3 showed superior long‐term survival versus legacy devices, driven by fewer hemocompatibility‐related adverse events, especially pump thrombosis and ischemic stroke, while major bleeding was similar across devices.
