PRISMA 2020 flow diagram for new systematic reviews which included searches of databases and registers only (4). ^*Consider, if feasible to do so, reporting the number of records identified from each database or register searched (rather than the total number across all databases). **Exclusion criteria included: review articles, meta-analyzes, conference abstracts, non-English language, animal and ex-vivo studies, non-AI methods, and those whose primary outcome is in the phase of care prior to transplantation or mechanical circulatory support.
