Our hypothesis is that by improving access to advanced heart failure specialists (AHFS) through partnered outreach clinics, we can increase the number of patients benefitted by advanced heart failure (AHF) therapies delivered at our center. This partnered network approach can potentially overcome distance barriers, optimize referral timing, and expedite access to AHFS from the regional
With the growing shortage of organ donors, marginal donor organs are increasingly accepted, which may partially explain the continued increase in donor age. The potential interactions between donor-recipient (D/R) age difference and outcomes after heart transplantation (HT) are not well known, and organ allocation systems do not routinely consider D/R age matching. We thus aimed
In this issue of the Journal, Profita and colleagues report findings from a well-controlled analysis matching outcomes from the Organ Procurement and Transplantation Network (OPTN) and the Extracorporeal Life Support Organization (ELSO) datasets to identify incidences of and risk factors for severe primary graft dysfunction (PGD) in pediatric heart transplant recipients within the United States.1
We previously reported a microarray-based diagnostic system for heart transplant endomyocardial biopsies (EMBs), using either 3-archetype (3AA) or 4-archetype (4AA) unsupervised algorithms to estimate rejection. The present study aimed to examine the stability of machine-learning algorithms in new biopsies, compare 3AA vs. 4AA algorithms, assess supervised binary classifiers trained on histologic or molecular diagnoses, create

Previous reports of primary graft dysfunction (PGD) in pediatric heart transplant (HT) recipients are limited to descriptive series of children who required extracorporeal membrane oxygenation (ECMO) support shortly after HT. In this study we sought to determine the incidence, risk factors, and survival after severe PGD in pediatric HT recipients.

A cross-functional team of UNOS staff and OPTN members is working on a data governance initiative to improve the consistency and quality of OPTN data collection. The first set of data definitions using a new format are published in UNet online Help as
The 36,527 organ transplants performed in the United States in 2018 set an annual
Identifying patients who are at risk for complications after thoracic transplantation assists in better defining outcomes and promoting discovery of new mechanisms that can be targeted to mitigate these complications. The gold-standard for diagnosing rejection, a major cause of morbidity and mortality after transplantation, is biopsy, which (1) is not risk-free, (2) may not be
Rejection with severe hemodynamic compromise (RSHC) carries a mortality risk approaching 50%. We aimed to identify current risk factors for RSHC and predictors of graft failure after RSHC.
