Filter by:Heart transplantation (HTx) is a procedure which is hindered by several complications. The HEARTS registry aims to allow the analysis of risk factors of all post-HTx complications. It consists in an exhaustive data collection at the moment of inclusion, i.e. HTx, knowing that patients underwent a full-fledged evaluation beforehand to evaluate their aptitude to being transplanted. Post-HTx complications include but is not limited to: all-cause mortality, AMR, ACR, CAV, AKI, sepsis, cancer, psychological disorders, metabolic disorders.
Despite major progress in molecular and phenotypic characterization of primary electrical disorders, many (aborted) sudden cardiac deaths (SCD) occur in young victims without identifiable abnormalities. Investigator recently identified, in 4 families presenting unexplained SCD, a new arrhythmia entity (catecholamine-induced QT prolongation; CIQTP) characterized by normal QT duration at rest but major QT lengthening during mental stress test (MST). Investigators aim to determine the prevalence of this new phenotype in unexplained SCD and identify its underlying pathophysiological mechanism. More specifically, investigators aim to: - determine the prevalence of CIQTP in unexplained SCD and identify new affected families; - identify the role of mental stress in QT prolongation; - identify the genetics basis underlying this life threatening disease; - perform transcriptomic and electrophysiological profiling of induced pluripotent stem cell-derived cardiomyocytes (iPSC-CM) from CIQTP patients to identify putative biomarkers and pathophysiological mechanisms. MST will be performed, additionally to the conventional screening, in families affected by unexplained SCD or long QT syndrome (LQTS) referred to university hospitals of Nantes, Rennes, Tours and Brest. Relevance of the MST on the different type of LQTS will be evaluated and compared to conventional provocative tests (epinephrine, exercise). Whole-genome sequencing will first be performed in 3 distantly affected relatives within each of the 4 largest families identified. As previously performed in Nantes, analysis of the shared rare variants will allow identifying gene(s) associated with the disease. Transcriptomic (high-throughput 3' Digital Gene Expression mRNA sequencing) and electrophysiological (96-well automated optical recordings of action potentials and patch-clamp recordings of ionic currents, using specific ion channel activators and inhibitors) profiling will be performed on iPSC-CMs from 2 affected and one unaffected first-degree relatives of these 4 large families.
Failing heart negative remodeling alterations might provide electrical heterogeneity and cardiac remodeling, thus potentially contributing to the occurrence of ventricular arrhythmia and subsequent sudden cardiac death (SCD). In this study we have prospectively investigated whether serum markers of heart failure (ultra sensitive Troponin , B type Natriuretic Peptide (BNP), C reactive protein (CRP), ST protein, and adiponectin could be used as predictors for the occurrence of malignant ventricular arrhythmias in patients who had received an Implantable Cardioverter Defibrillator (ICD) for primary prevention and treated by catheter ablation for ventricular arrhythmias.
The aim of the study is to evaluate a health workforce capacity building and quality improvement intervention focused on integrated day-of-birth and post-pregnancy care at 16 hospitals in Kinshasa, Democratic Republic of Congo. The intervention package consists of a low-dose, high-frequency (LDHF) training of health workers, support for quality improvement teams, and provision of critical equipment, supplies and drugs within a quality improvement (QI) framework.
The implantable device therapy for cardiac arrhythmias has been an established therapy, and one of the common standard procedures in cardiac clinical practice. Pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy have been developed since 1960s, and the technologies in this field are still progressively developing. Not only these "traditional" implantable devices, there are multiple new devices for cardiac diseases, such as implantable loop recorder, vagal nerve stimulator and barostimulator. The aim of this registry is to demonstrate the efficacy and the safety of standard device implantation procedures and to evaluate/ identify specific factors, including clinical characteristics, laboratory data and procedural data, which predict the prognosis/complication of the patients. These identification will result in further improvement of patients' care.
Infant mortality is still relevant despite the improvement and the accessibility of hospital care. Premature birth are two fold higher than in metropolitan France. Some factors has been suspected such as precariousness, alcoholism, congenital malformation, care accessibility, epidemic environment ... Nevertheless, the impact of these factors on foetal death or new-born death are not yet sufficiently quantified to provide appropriate care and prevention action in Reunion Island.
Assessment of the psychological benefit of the proposition by prehospital medical team of a sudden death counselling on family members of sudden death victims.
This post-market study is a prospective observational study evaluating the efficacy and safety of the LifeVest in real-life settings.
The proposed study will adapt and pilot test an efficacious advance care planning interventions, Sharing Patient's Illness Representations to Increase Trust (SPIRIT), with patients with mild dementia and their surrogates to promote open, honest discussions while such discussions about end-of-life care are possible. Patient and surrogate decision maker dyads will participate in a single SPIRIT session and will then have a follow up phone call 2-3 days later. One year after the SPIRIT session some surrogates will be contacted to provide additional feedback about the intervention.
This study aims to demonstrate that the BioFreedom™ Cobalt Chromium Drug Coated Stent is non-inferior to the market authorized BioFreedom™ Stainless Steel Stent with respective to efficacy and shows a similar safety profile.
