Filter by:The goal of this study is to evaluate if hypertonic saline solution can prevent or attenuate acute kidney injury after heart transplantation in the early postoperative phase.
The evolution of systemic microvascular reactivity may aid in the comprehension of cardiovascular physiology in heart transplantation patients, and possibly suggest the non-invasive evaluation of skin microcirculation as an ancillary tool in the clinical evaluation of these patients.
Postoperative Acute Kidney Injury (AKI) is a common complication after heart transplantation (HTX) affecting outcome of patients. Remote ischemic preconditioning (RIPC) is an intervention that showed positive effect on incidence of AKI in elective cardiac surgery. Effects of RIPC on AKI in HTX patients have not been investigated to date. Recently new biomarkers have been established, showing high sensitivity and specificity for AKI. Especially, Insulin-Like Growth Factor Binding Protein 7 (IGFBP7) together with Tissue Inhibitor of Metalloproteinases-2 (TIMP-2), known as nephrocheck®, are diagnostic biomarkers in this context. Hence, the investigators want to conduct a randomized controlled feasibility and proof of concept trial to determine the effects of RIPC on AKI after HTX, defined/detected using postoperative urinary [TIMP-2]*[IGFBP-7] concentration.
To investigate whether the use of haemoadsorption (HA) on cardiopulmonary bypass during heart transplantation (HTX) has an effect on circulating cytokine levels for the first 120 hours after HTX and induces a decreased inflammatory response, increased anti-inflammatory response or immunosuppressive response. Additionally, the influence of HA on primary graft dysfunction, postoperative cerebral dysfunction, postoperative fluid accumulation, renal dysfunction, duration of mechanical ventilation, length of ICU-stay and 30-day mortality should be investigated
With stress echo (SE) 2020 study, a new standard of practice in stress imaging was developed and disseminated: the ABCDE protocol for functional testing within and beyond CAD. ABCDE protocol was the fruit of SE 2020, and is the seed of SE 2030, which is articulated in 12 projects: 1-SE in coronary artery disease (SECAD); 2- SE in diastolic heart failure (SEDIA); 3-SE in hypertrophic cardiomyopathy (SEHCA); 4- SE post-chest radiotherapy and chemotherapy (SERA); 5- Artificial intelligence SE evaluation (AI-SEE); 6- Environmental stress echocardiography and air pollution (ESTER); 7- SE in repaired Tetralogy of Fallot (SETOF) ; 8- SE in post-COVID-19 (SECOV); 9: Recovery by stress echo of conventionally unfit donor good hearts (RESURGE); 10- SE for mitral ischemic regurgitation (SEMIR); 11- SE in valvular heart disease (SEVA); 12- SE for coronary vasospasm (SESPASM). The study aims to recruit in the next 5 years (2021-2025) ≥10 000 patients followed for ≥5 years (up to 2030) from ≥20 quality-controlled laboratories from ≥10 countries. In this COVID-19 era of sustainable health care delivery, SE2030 will provide the evidence to finally recommend SE as the optimal and versatile imaging modality for functional testing anywhere, any time and in any patient.
Heart Failure (HF) is a complex disease associated with the highest burden of cost to the healthcare system. The cardiopulmonary exercise test (CPET) is instrumental in determining the prognosis of patients with HF. This study will evaluate whether aggregate biometric data from the Apple Watch combined with demographic, cardiac, and biomarker testing can improve our ability to predict heart failure outcomes among a diverse ambulatory HF population
The investigators developed a protocol to isolate Treg cells from thymic tissue (thyTreg) discarded in pediatric cardiac surgeries. After completing the pre-clinical studies, the investigators have initiated a phase I/II clinical trial to test the safety and efficacy of the adoptive transfer of autologous thyTreg to prevent rejection in heart transplant children. Condition or disease: Heart Transplantation Intervention/treatment: Regulatory T Cell (Treg) Infusion
The purpose of this study is to determine if Belatacept is safe to give to adult heart transplant recipients. Belatacept (NULOJIX) is an anti-rejection medication that is available through a prescription from a doctor. In this research study, belatacept is being used in an investigational manner (not for the purpose that it is approved for).
Severe heart failure is a diagnosis with a very poor prognosis. Heart transplantation is the best treatment for terminal heart failure but this type of treatment is limited by the number of available organs. About 20-25% of possible donor hearts are not considered for transplantation because they have some form of functional impairment. The functional impairment affecting organ donors is, however, usually reversible. A number of retrospective studies show that cardiac function recovers and recipients of hearts with dysfunction do not have worse outcomes compared to recipients of hearts with perfect cardiac function. However, there are no prospective studies on whether the functional impairment of the donor heart is of significance for the recipient. With a systematic and simple investigation of the heart, it should be possible to identify the hearts that are safe to transplant. This will thus increase the number of available donors.
