Background The total artificial heart (TAH) is an implanted device approved as a modality to stabilize patients with severe biventricular heart failure or persistent ventricular arrhythmias for evaluation and bridge to transplantation. According to the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS), about 450 patients received a TAH between 2006 and 2018. Patients being evaluated for a TAH are often critically ill and a TAH offers the best chance at survival. Given the prognostic uncertainty of these patients, there is a crucial need for preparedness planning to help patients and their caregivers plan for living and supporting a loved one with a TAH.

Aim To describe an approach to preparedness planning and highlight the importance of palliative care.

Methods We reviewed the current needs and approaches to preparedness planning for a TAH. We categorized our findings and suggest a guide to maximize conversations with patients and their decision makers.

Results We identified four critical areas to address: the decision maker, minimal acceptable outcome/maximal acceptable burden, living with the device, and dying with the device. We suggest using a framework of mental and physical outcomes and locations of care as a way to identify minimal acceptable outcome and maximal acceptable burden.

Conclusion Decision making for a TAH is complex. There is an urgency and patients do not always have capacity. Identifying legal decision makers and social support is critical. The surrogate decision makers should be included in preparedness planning including discussions about end-of-life care and treatment discontinuation. Having palliative care as members of the interdisciplinary mechanical circulatory support team can assist in these preparedness conversations.
