Toward Wireless Implantable Robotic Systems Driven by Magnetic Field for Personalized Therapy

open access: yesAdvanced Robotics Research, EarlyView.
Robotic materials are playing an increasingly vital role in enabling sensing and actuation at small scales. This perspective highlights recent advances in magnetic materials and magnetically actuated devices for wireless sensing, actuation, and energy harvesting toward implantable robotic systems for closed‐loop therapy.

Cardiac Catheterization and Outcomes for Elderly Patients Hospitalized With Heart Failure

open access: yesHealth Services Insights
Background: Heart failure affects over 6 million people in the United States (US) with limited evidence to support the use of cardiac catheterization. The benefit of its use remains mostly as expert opinion.

Transcatheter closure of Ventricular Septal defects in Malta : initial experience [PDF]

open access: yes, 2005
Ventricular septal defects (VSD) consist of deficiencies of the wall separating the two ventricles. VSDs are the commonest congenital cardiac defects. Small VSDs rarely require intervention, however, larger defects cause ventricular volume overload with ...

Brugada Syndrome: Presentation and Management of the Atypical Patient in the Emergent Setting [PDF]

open access: yes, 2020
Introduction: Brugada syndrome is a genetic disorder of the heart’s electrical system that increases a patient’s risk of sudden cardiac death. It is a syndrome most prevalent in Southeast Asians and is found 36 times more commonly in Asians than in ...

A Superlubricated Magnetically Steerable Microcatheter with Integrated Optical and Fluidic Channels

open access: yesAdvanced Robotics Research, EarlyView.
A magnetically steerable microcatheter with integrated optical and fluidic channels is developed for multifunctional navigation in tortuous anatomical environments. A surface‐grafted hydrogel coating enables low‐friction actuation. The device demonstrates stable light and fluid delivery during magnetic manipulation, offering a compact platform for ...

Echocardiographic Detection of Occult Diastolic Dysfunction in Pulmonary Hypertension After Fluid Challenge

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Identification of occult diastolic dysfunction often requires invasive right heart catheterization with provocative maneuvers such as fluid challenge. Non‐invasive predictors of occult diastolic dysfunction have not been identified.

Waveguide Photoactuators: Materials, Fabrication, and Applications

open access: yesAdvanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

A patient with acute myocardial infarction with electrocardiogram Aslanger’s pattern

open access: yesBMC Cardiovascular Disorders
Background Aslanger’s pattern in electrocardiogram (ECG) indicates that patients may have acute inferior myocardial infarction(AMI) with concomitant critical stenoses on other coronary arteries, which needs to be evaluated the timing of revascularization

NARFL Knockout Triggers Ferroptosis‐Driven Vascular Endothelial Dysfunction

open access: yesAdvanced Science, EarlyView.
NARFL is vital for CIA and oxidative stress resistance. NARFL deletion in HPMEC cells, zebrafish, and mice is lethal and rescued by a Ferroptosis inhibitor. NARFL deficiency disrupted its interaction with CIA proteins, decreased aconitase activity, increased IRP1 activity, induced Fe overload, and led to ferroptosis and oxidative stress, resulting in ...

Cardiac catheterization in pulmonary arterial hypertension: Tips and tricks to enhance diagnosis and guide therapy

open access: yesInternational Journal of Cardiology Congenital Heart Disease
Cardiac catheterization (CC) is essential for the diagnosis of pulmonary hypertension (PH), and for its characterisation. It allows distinction between pre- and post-capillary PH which, when integrated with other non-invasive data, facilitates ...
