Physiological Control of Realheart Total Artificial Heart

Artificial Organs, EarlyView.
This study evaluates the Realheart Total Artificial Heart's preload‐based physiological controller, which dynamically adjusts heart rate and stroke volume to mimic the heart's natural responses during sleep, rest, and exercise using a hybrid mock circulation loop of the cardiovascular system.

Sex-related differences in prosthesis-patient mismatch following aortic valve replacement with the edwards intuity valve system

Frontiers in Cardiovascular Medicine
BackgroundProsthesis-patient mismatch (PPM) is linked to a poor prognosis following surgical aortic valve replacement (SAVR). The exploration of sex differences in PPM outcomes is currently limited.

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

Outcomes for Congenital Diaphragmatic Hernia in Three Decades: A Report From a UK Surgical Centre

Acta Paediatrica, EarlyView.
ABSTRACT Aims Congenital diaphragmatic hernia (CDH) is associated with lung hypoplasia, pulmonary hypertension and high mortality. Three decades experience from a UK centre is reported. Methods Medical records of CDH newborns between February 1990 and November 2021 and attending a multidisciplinary clinic were examined. Survival and health outcomes are
