Soft Beats: A Dielectric Elastomer‐Based Ventricular Assist Device for Next‐Gen Heart Failure Management

Advanced Engineering Materials, Volume 27, Issue 20, October 2025.
The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

Advanced Materials, Volume 37, Issue 40, October 9, 2025.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Artificial Nervous Systems

Advanced Science, Volume 12, Issue 40, October 27, 2025.
By drawing inspiration from biological neural hierarchies and the working mechanisms of plasticity, researchers have constructed a series of bionic devices, including sensory devices, synapse devices, and artificial neural systems. They committed to simulating and surpassing the biological information processing function, thereby realizing the ...

Utilização de valvas homólogas e heterólogas em condutos extracardíacos The use of homograph and heterograph valves in extracardiac conduits

Brazilian Journal of Cardiovascular Surgery, 1988
O conceito do uso de um conduto extracardíaco para estabelecer uma via de saída, conectando o ventrículo direito com o tronco pulmonar, ou seus ramos, foi desenvolvido na década de 60.

Transcaval Transcatheter Aortic Valve Replacement: Clinical Outcomes From a TAVI Program Without Prior Transcaval Experience

Catheterization and Cardiovascular Interventions, Volume 106, Issue 4, Page 2592-2600, October 1, 2025.
ABSTRACT Background Despite the emergence of the transcaval (TCv) access route for transcatheter aortic valve implantation (TAVI) in the treatment of patients with hostile iliofemoral anatomy, the number of patients reported in clinical series of TCv TAVI has been relatively small (< 500 published cases). We assessed procedural and clinical outcomes in

Balloon‐Expandable Versus Self‐Expanding Valves in Bicuspid Aortic Stenosis: Insights From the SWEDEHEART Registry

Catheterization and Cardiovascular Interventions, Volume 106, Issue 4, Page 2336-2347, October 1, 2025.
ABSTRACT Background Transcatheter aortic valve replacement (TAVR) is increasingly used in patients with bicuspid aortic valve (BAV) stenosis, but there is limited comparative data on balloon‐expandable (BEV) versus self‐expanding valves (SEV) in this population. Aim To compare clinical and hemodynamic outcomes between BEVs and SEVs in patients with BAV
