Artificial 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
Artificial 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
Artificial 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
Artificial 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.

Brazilian Journal of Cardiovascular Surgery, 1988 No período de março de 1981 a março de 1988, foram implantadas 2324 biopróteses, em 2016 pacientes, em 5 Centros do Estado de Minas Gerais. Este estudo inclui somente a análise dos pacientes submetidos a troca valvar aórtica (n = 603) e mitral ( n = 1110)
