Introduction. Cardiovascular diseases are the number one cause of death globally contributing to 37% of all global deaths. A common complication of cardiovascular disease is heart failure, where, in such cases, the only solution would be to conduct a heart transplant. Every 10 minutes a new patient is added to the transplant waiting list. However, a shortage of human donors and the short window of time available to find a correct match and transplant the donors' heart to the recipient means that numerous challenges are faced by the patient even before the operation could be done, reducing their chances of living even further. Methods. This review aims to evaluate the application of the Organ Care System (OCSTM) in improving the efficiency of heart storage based on journal articles obtained from PubMed, Elsevier Clinical Key, and Science Direct. Results. Studies have shown that OCS is capable of extending the ischemic time 120 minutes longer than conventional methods without any detrimental effect on the recipient nor donor's safety. Based on the PROTECT I and PROCEED II study, 93% of transplantation recipients using the OCS system passed through the 30-day mortality period. Discussion. OCS is able to prolong the ischemic time of donors' hearts by perfusing the organ at 34°C in a beating state, potentially reducing the detrimental effect of cold storage and providing additional assessment options. Another clear advantage is the implanting surgeon can assess the quality of the donor heart before surgery as well as providing a time safety buffer in unanticipated circumstances that will reduce the mortality risk of transplant recipients.
