Three Ventricular Assist Devices (True TriVAD) as Bridge to Durable Biventricular Support (BiVAD) in LVAD Patient With Severe Aortic Regurgitation

Artificial Organs, EarlyView.
An LVAD patient with severe aortic regurgitation (AR) developed right heart failure and multi‐organ dysfunction (MOD). tRVAD support caused LV overload and pulmonary edema. Impella 5.5 implantation successfully unloaded the LV and stabilized the patient, enabling durable RVAD implantation with surgical aortic valve replacement.

An intelligent nanoreservoir system promotes heart valve regeneration via ROS scavenging and immunomodulation

Bioactive Materials
In situ regeneration of tissue-engineered heart valves (TEHV) is a promising strategy to overcome the limitations of existing heart valve prostheses. Although, decellularized aortic valves (DAVs) are widely regarded as a scaffold in the construction of ...

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

Artificial 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.

Purinergic ecto-enzymes in human and ovine aortic valves: indicators of bacterial nanocellulose scaffold cellularization

Artificial Cells, Nanomedicine, and Biotechnology
Purinergic signalling pathways play a vital role in the biological functions of the aortic valve (AV) through nucleotide and adenosine-dependent receptor effects.

Outcomes in Patients Requiring VENO‐Venous Extracorporeal Membrane Oxygenation After Cardiac Surgery: An Analysis From the PELS‐1 Study

Artificial Organs, EarlyView.
We report an insight from the PELS‐1– a multicentre, international registry focusing on postocardiotomy extracorporeal support use between 2000 and 2020. We focused on 24/2163 (1.1%) patients requiring V‐V ECMO after cardiac surgery. Mortality was high, with 21.7% of patients discharged alive and an overall 1‐year survival probability of 12.5 ...

A Farewell to Arms… Manufacturing: Learning From a Landmine Producer Who Became a Deminer

Business Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT Certain industries—labeled “dirty,” “sinful,” “stigmatized,” or “controversial”—are under public scrutiny because of the ethical, social, and environmental concerns that they raise. Previous research has typically focused on the industry or organizational level of analysis, examining how companies in controversial industries can enhance their ...

Structural evolution of mechanical heart valves (review)

Вестник трансплантологии и искусственных органов
Prosthetic heart valves are widely used biomedical devices. The need for these prostheses is increasing due to the increasing life expectancy of the general population and the consequent incidence of age-related degenerative valvular defects.

Cardiovascular Health in Women—Across the Lifespan

Clinical Endocrinology, EarlyView.
ABSTRACT Cardiovascular disease (CVD) remains the leading cause of mortality and morbidity among women worldwide. However, CVD continues to be perceived as a predominantly male issue. CVD in women therefore remains understudied, underrecognized and undertreated.
