HeartMate III Autonomy Assistant in a Hemiplegic Left Ventricular Assist Device Patient: A Case Report

Terminal heart failure presents challenges, requiring cardiac transplantation, or mechanical circulatory support. Limited donor organ availability has made mechanical support crucial. Advances in centrifugal-flow systems, compared to axial-flow, have improved patient outcomes by reducing adverse events. Rehabilitation is vital for patient independence postimplantation. We developed a tool to aid hemiplegic patients in managing power sources. A 44 year old male with tritroncular ischemic heart disease and a 15% ejection fraction. He underwent a double bypass and left ventricular assist device (LVAD) implantation while awaiting a transplant. Postsurgery, the patient suffered a stroke, leading to left motor impairments. To assist in managing LVAD power sources, an autonomous tool with a Woodcast support base and antislip surface was developed. The tool improves autonomy and quality of life for motor-impaired patients. It is designed to be portable, adaptable, supporting various mobility levels. Real-world evidence shows it reduces time and alarms for battery changes, proving effective in home settings. The tool significantly enhances hemiparetic patients' self-care and independence, showing promise for motor-impaired individuals. Further research is needed to evaluate long-term benefits and challenges.
