RESUMO
The past 5 years have posed challenges to the field of heart transplantation. The 2018 heart allocation policy revision was accompanied by anticipated practice adjustments and increased use of short-term circulatory support, changes that may ultimately serve to advance the field. The COVID-19 pandemic also had an impact on heart transplantation. While the number of heart transplants in the United States continued to increase, the number of new candidates decreased slightly during the pandemic. There were slightly more deaths following removal from the waiting list for reasons other than transplant during 2020, and a decline in transplants among candidates listed as status 1, 2, or 3 compared with the other statuses. Heart transplant rates decreased among pediatric candidates, most notably among those younger than 1 year. Despite this, pretransplant mortality has declined for both pediatric and adult candidates, particularly candidates younger than 1 year. Transplant rates have increased in adults. The prevalence of ventricular assist device use has increased among pediatric heart transplant recipients, while the prevalence of short-term mechanical circulatory support, particularly intra-aortic balloon pump and extracorporeal membrane oxygenation, has increased among adult recipients.
