Real-time Pressure Volume Loop Monitoring as a Guide for Enhanced Understanding of Changes in Elemental Cardiovascular Physiology During Therapeutic Strategies Aiming for Hemodynamic Optimization. Cohort II: Structural Heart Interventions (PLUTO-II)
The aim of PLUTO-II is to use biventricular pressure-volume (PV) loop measurements to improve the understanding of direct changes in cardiac and hemodynamic physiology induced by transcatheter aortic valve implantation (TAVI) or tricuspid edge-to-edge repair (TEER). These procedures evoke immediate changes in cardiac mechanoenergetics, ventricular-vascular interaction as well as ventricular …
A Single-cell Approach to Identify Biomarkers of Efficacy and Toxicity for ICI in NSCLC
The main goal of this prospective non-interventional exploratory study is to characterize the tumor micro-environment of advanced NSCLC in single-cell resolution, prior to immune checkpoint blockade exposure, and correlate the findings to clinical outcome. This approach will allow to generate new hypotheses regarding mechanism of action of ICI and (primary) …
Arterial Embolism After Catheter Ablation of Atrial Fibrillation. ATRIAL FIBRILLATION
The EMBOL-AF is a multicenter, international, observational study designed as a retrospective registry that will investigate the characteristics of systemic arterial embolic events after treatment of atrial fibrillation by catheter ablation. Due to the retrospective nature of the study, the registry is specially focused on cerebral embolism (stroke and TIA) …
Liver and Spleen Stiffness Measured by TE and 2D-SWE for Diagnosis of CSPH in Patients With cACLD
A observational diagnostic study will be conducted to compare the performance of liver stiffness and spleen stiffness measured by 2D-shear wave elastography (2D-SWE) and transient elastography (TE) for diagnosing clinically significant portal hypertension (CSPH) in people with compensated Advanced Chronic Liver Disease (cACLD), and explore the cut-off value of 2D-SWE …
68Ga-HER2 Affibody PET/CT Imaging for HER2-Positive Cancer Patients
The prevalence of HER2 alterations in pan-cancer indicates a broader range of application of HER2-targeted therapies. immunohistochemistry (IHC) or amplification by fluorescence in situ hybridization (FISH) is currently the most commonly used method for evaluation of HER-2 status in cancer patients. However, biopsies are spatiotemporally limited because of the highly …
Facilitating Diagnostics and Prognostics of Parkinsonian Syndromes Using Neuroimaging
The goals of this study are: 1) to identify biomarkers using neuroimaging that are associated with progression rate using statistical methods, and 2) to identify biomarkers that are associated with the differential diagnosis of Parkinson's disease and atypical parkinsonism.
ctDNA Detection of MRD in Predicting Postoperative Recurrence in Biliary Tract Cancers：A Multicenter Prospective Trial
A substantial proporation of patients with biliary tract malignancies still experience disease recurrence after curative resection. ctDNA-based minimal residual disease (MRD) method has been widely used to monitor postoperative recurrence in solid cancers, but few studies have been reported in biliary tract cancers. The present clinical trial aims to elucidate …
Estrogen Receptor (ER) PET/CT Imaging in Breast Cancer
18F-Fluoroestradiol (18F-FES) is an estrogen receptor-targeting positron emission tomography tracer with high sensitivity and specificity for the detection of estrogen receptor（ER）-positive tumors . 18F-FES has been used as a predictive biomarker to demonstrate estrogen receptor heterogeneity , to evaluate the pharmacokinetics of estrogen receptor-targeted drugs ， to measure residual estrogen …
Assessment of Adults Epidemiological Characteristics of Status Epilepticus in the French West Indies and in French Guiana
The justification of this prospective and multicenter study is based on the absence of published data concerning, status epilepticus (SE), a pathology which seems frequent in the French West Indies (FWI) and French Guiana, and whose etiological and prognostic characteristics are often mentioned or assumed but which remain to be …
Retrospective Analysis of Performance and Treatment Data Collected for Genius SleddFlux Filter, Ultraflux AV 600 S Filter & Genius 90 Concentrates in Haemodialysis Patients
Retrospective analysis of performance and treatment data collected for Genius SleddFlux Filter, Ultraflux AV 600 S Filter & Genius 90 Concentrates in acute haemodialysis, haemodynamically instable patients and chronic haemodialysis patients to analyse performance and treatment data from patients treated with the investigational device to evaluate the filter characteristics for …
