BACKGROUND: In an effort to address the increasing demand for heart transplantation within the United Kingdom (UK), we established a clinical program of heart transplantation from donation after circulatory-determined death (DCD) donors in 2015. After 5 years, we report the clinical early outcomes and impact of the program. METHODS: This is a single-center, retrospective, matched, observational cohort study comparing outcomes of hearts transplanted from DCD donors from March 1, 2015 to February 29, 2020 with those from matched donation after brain death (DBD) donors at Royal Papworth Hospital (RPH) (Cambridge, UK). DCD hearts were either retrieved using thoracoabdominal normothermic regional perfusion or the direct procurement and perfusion technique. All DBD hearts were procured using standard cold static storage. The primary outcomes were recipient 30-day and 1-year survival. RESULTS: During the 5-year study, DCD heart donation increased overall heart transplant activity by 48% (79 for DCD and 164 for DBD). There was no difference in survival at 30 days (97% for DCD vs 99% for DBD, p = 1.00) or 1 year (91% for DCD vs 89% for DBD, p = 0.72). There was no difference in the length of stay in the intensive care unit (7 for DCD vs 6 for DBD days, p = 0.24) or in the hospital (24 for DCD vs 25 for DBD days, p = 0.84). CONCLUSIONS: DCD heart donation increased overall heart transplant activity at RPH by 48%, with no difference in 30-day or 1-year survival in comparison with conventional DBD heart transplantations.
Clinical (short stature, macrocephaly, constipation) and biochemical (low free T4/free T3 ratio, subnormal rT3) findings that are congruent with previous cases and newly recognized features (epilepsy) in this adult female with defective TRα define a shared phenotype in TRα-mediated resistance to thyroid hormone, with differential tissue responses to T4 treatment.
Patent foramen ovale (PFO) is a normal fetal communication between the right and left atria that persists after birth. PFO is a common finding that occurs in 20-34% of the population, although its prevalence decreases with age. In most cases, a PFO poses no threat to health. However, some PFOs have the ability to open widely under certain hemodynamic conditions, which enables any bloodborne material, such as thrombi, air, or vasoactive substances, to pass from the venous to the arterial circulation, with the potential to cause a cerebrovascular event. PFO has been linked to several conditions, including cryptogenic stroke, migraine with aura, decompression illness, and systemic arterial embolism. However, the data that support PFO closure in these conditions are mostly from nonrandomized cohort series, and are often contradictory. In this Review, we discuss the existing data on PFO closure, including results of the first randomized, controlled trial comparing device closure of PFO with medical therapy for cryptogenic stroke, and we examine controversies in the literature as well as ongoing studies. We also focus on the anatomy of a PFO and how it impacts on the procedure of PFO closure with a percutaneous device.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
