Special Issue Information
Dear Colleagues,
Cardiothoracic Assist Devices (CADs) have undergone transformative advancements in recent years, revolutionizing the management of advanced heart failure. This Special Issue highlights cutting-edge innovations in cardiopulmonary and mechanical circulatory support (MCS), including ventricular assist devices (VADs), total artificial hearts (TAHs), an Organ Care system (OCS), Lung bioengineering (LBE), EVLP (Ex vivo lung perfusion), bonded circuits and minimally invasive systems, with a focus on improving durability, interface biocompatibility, and patient outcomes.
Key themes explored in this Special are as follows:
- Next-Generation VADs: The shift toward fully magnetically levitated (maglev) pumps (e.g., HeartMate 3) has significantly reduced complications like thrombosis and hemolysis, while enhancing long-term survival.
- Minimally Invasive and Pediatric Solutions: Devices such as Impella 5.5® and miniaturized pediatric VADs are expanding treatment options for diverse patient populations.
- Wireless Power and Smart Systems: Advances in transcutaneous energy transfer (TET) and AI-driven adaptive control are minimizing infections and optimizing hemodynamic performance.
- Bioprosthetic and Total Artificial Hearts: Innovations like the Carmat TAH and SynCardia’s portable drivers are improving outcomes in biventricular failure.
- An OCS, LBE and EVLP for cardiac and pulmonary support and evaluation for transport of harvested hearts and lungs are discussed.
- Biocompatibility and Hemocompatibility: Novel coatings (e.g., heparin, endothelial cell-seeded surfaces) aim to reduce anticoagulation needs.
This collection of research underscores the rapid evolution of CADs toward smaller, smarter, and more physiological systems, offering new hope for heart failure patients through better organ preservation during transport, organ evaluation to increase transplant success rates, destination therapy, bridge-to-transplant, or recovery. Future directions, including bioengineered solutions and fully implantable systems, are also discussed, paving the way for the next era of cardiac support.
We invite readers to explore the breakthroughs that are reshaping the landscape of advanced heart failure therapy.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Bioengineering is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
