heart transplantation<\/a>\u00a0remains\u00a0the definitive treatment for end stage disease, donor shortages limit availability.\u00a0\u00a0<\/p>\nMechanical circulatory support devices can provide\u00a0lifesaving\u00a0assistance, but their use is restricted by complications including thrombosis, infection, driveline failure, and the need for lifelong anticoagulation.\u00a0<\/p>\n
Soft robotic cardiac sleeves have\u00a0emerged\u00a0as an alternative strategy designed to avoid direct interaction with circulating blood.\u00a0\u00a0<\/p>\n
Rather than pumping blood, these devices envelop the heart and provide synchronised external compression, torsion, and relaxation to support cardiac function.\u00a0<\/p>\n
Preclinical Progress Highlights Potential\u00a0<\/p>\n
According to the review, soft robotic cardiac sleeves have progressed from\u00a0proof-of-concept\u00a0systems to sophisticated preclinical platforms capable of reproducing physiological cardiac mechanics and improving haemodynamic performance.\u00a0<\/p>\n
Researchers reported that\u00a0sleeve-based\u00a0technologies may support a range of cardiac conditions, including systolic dysfunction, diastolic dysfunction, conduction disorders, and severe ventricular impairment.\u00a0\u00a0<\/p>\n
By replicating natural myocardial motion, these systems aim to restore cardiac output while preserving more physiological heart mechanics than conventional assist devices.\u00a0<\/p>\n
Recent preclinical studies\u00a0demonstrated\u00a0restoration of cardiac output and ventricular performance in large animal models.\u00a0<\/p>\n
Researchers\u00a0also explored adaptive systems that synchronise\u00a0assistance\u00a0with electrical activity or pressure signals, advancing the concept of closed loop cardiac support.\u00a0<\/p>\n
Despite these advances, most evidence remains limited to acute or short duration studies. Long-term data examining durability, biological integration, and safety are still lacking.\u00a0<\/p>\n
Barriers to Clinical Translation\u00a0<\/p>\n
The review\u00a0identified\u00a0durable epicardial integration as one of the most significant barriers to clinical implementation.\u00a0\u00a0<\/p>\n
Achieving effective force transmission while\u00a0maintaining\u00a0biological compatibility, coronary safety, and device reversibility\u00a0remains\u00a0an unresolved challenge.\u00a0<\/p>\n
Additional\u00a0concerns include inflammatory responses, fibrotic encapsulation, thermal safety, long term mechanical reliability, and the development of implantable power and control systems.\u00a0\u00a0<\/p>\n
The authors also highlighted the need for standardised surgical workflows and clearer regulatory pathways.\u00a0<\/p>\n
Future development is expected to focus on patient specific designs, regionally targeted actuation, wireless power delivery, integrated sensing technologies, and biologically informed interfaces.\u00a0\u00a0<\/p>\n
The review concluded that successful clinical translation\u00a0will\u00a0depend on multidisciplinary collaboration across cardiology, cardiac surgery, biomaterials science, soft robotics, and bioelectronics engineering.\u00a0<\/p>\n
