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.

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers

Journal of the American Heart Association, EarlyView., 2021
Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.

Preoperative Atrial Fibrillation Does Not Impact Long‐Term Survival and Complications in Left Ventricular Assistance Device Recipients

Artificial Organs, EarlyView.
In this large multicenter study, AF before LVAD implantation was not associated with increased risks of mortality, bleeding, stroke, or pump thrombosis, but was linked to a higher incidence of late VAs. ABSTRACT Introduction A substantial proportion of patients receiving left ventricular assist devices (LVADs) present with pre‐existing atrial ...

Leveraging the ADAM10 prodomain for selective inhibition to enhance recovery after myocardial infarction

British Journal of Pharmacology, EarlyView.
Background and Purpose Inflammation plays a crucial role in the development and progression of numerous acute and chronic diseases such as myocardial infarction (MI) and heart failure. Targeting ADAM proteases, particularly ADAM10, holds promise for fine‐tuning inflammatory responses.

Neural Organoids Protect Engineered Heart Tissues From Glucolipotoxicity by Transferring Versican in a Co‐Culture System

Cell Proliferation, EarlyView.
In this study, Bai et al. established a co‐culture system between neural organoids (NOs) and engineered heart tissues (EHTs) and demonstrated that NOs could secrete versican, which was absorbed by EHTs to ameliorate glucolipotoxicity. ABSTRACT Metabolic disorders could cause dysregulated glucose and lipid at the systemic level, but how inter‐tissue ...

PHGDH Orchestrates Cell Cycle Progression to Drive Cardiomyocyte Proliferation and Myocardial Regeneration via TGF‐β/Smad Signalling Pathway

Cell Proliferation, EarlyView.
PHGDH promoted cardiomyocyte proliferation and myocardial regeneration via cell cycle and TGF‐β/Smad signalling pathways during cardiac repair. Moreover, PHGDH benefits cardiac repair and cardiomyocyte proliferation in mammalian mice following MI. ABSTRACT The mature mammalian heart has limited ability for self‐repair and regeneration.
