This research is being done to see if proton beam radiation therapy (PBT) results in fewer changes to a participant's heart measured with MRI-imaging than conventional or "photon" radiation therapy (XRT) for participants with non-metastatic left sided breast cancer. The names of the two study groups in this research study are: - Proton Radiation Therapy (PBT) - Conventional or "Photon" Radiation Therapy (XRT)
The purpose of this study is to evaluate the safety of fibroblast activating protein receptor imaging agent [68Ga]/ Fluorine [18F] -fibroblast activating protein inhibitor (68Ga/18F-FAPI-04) in clinical application and to verify its effectiveness in the diagnosis of cardiovascular diseases.
This study is being done to see if losartan affects the chances of developing radiation-induced heart failure in patients who are receiving radiation therapy as part of standard of care treatment for breast cancer. The interventions involved in this study are: - Losartan - Radiation Therapy (standard of care)
Background: Severe aortic valve stenosis (AS) is the commonest valve disease. Aortic valve replacement (AVR) is primarily indicated when symptoms occur and/or when there is a drop in left ventricular ejection fraction. However, irreversible myocardial damage, such as replacement fibrosis, leads to increased morbidity and mortality despite treatment. Improved patient selection and timely treatment is thus warranted. T1 mapping, a non-invasive method to quantify myocardial fibrosis by cardiac magnetic resonance (CMR), could be a marker to guide treatment. Aims: To investigate the change of myocardial fibrosis* in AS patients following AVR and if these changes are associated with disease and/or procedural characteristics. Methods: This is an observational clinical trial. Approximately 60 patients with severe AS planned to undergo AVR (either surgical or transcatheter) at Rigshospitalet, Denmark will be included. Participants will undergo CMR before surgery and at a 1-year follow-up. Other assessments include clinical evaluation and blood sampling. The primary end-point is change in T1 values after AVR. Hypotheses and perspectives: The investigators hypothesize that (1) myocardial fibrosis* will regress in patients undergoing AVR as a group, (2) the degree of myocardial fibrosis is positively correlated with the degree of symptoms, (3) the regression of myocardial fibrosis is greater in patients undergoing TAVR compared to SAVR, and (4) the regression of myocardial fibrosis is greater in patients with tricuspid aortic stenosis compared to bicuspid aortic stenosis. Ultimately, T1 mapping is a potential marker for improved patient selection for the timing of AVR. * Estimated by T1 mapping
The purpose of this study is to test the safety and preliminary efficacy of AAVrh.10hFXN to treat the cardiomyopathy associated with Friedreich's ataxia (FA). AAVrh.10hFXN is a serotype rh.10 adeno-associated virus gene transfer vector coding for Frataxin (FXN). The drug is administered intravenously. This is a phase 1, open label, dose escalation study with a total of 10 participants.
This is a single arm prospective pilot trial that evaluates the ability of a novel imaging agent (68Ga-FAP-2286) to identify pathologic fibrosis in the setting of hepatic, cardiac and pulmonary fibrosis. FAP-2286 is a peptide that potently and selectively binds to Fibroblast Activation Protein (FAP). FAP is a transmembrane protein expressed on fibroblasts and has been shown to have higher expression in idiopathic pulmonary fibrosis (IPF), cirrhosis, and cardiac fibrosis.
This is a single-center, prospective, observational controlled cohort study designed to describe the role of WNT/B-catenin signaling and adenosine system after an acute myocardial infarction, correlating it with clinical markers of fibrosis/remodeling (primary objective). The modulation of the aforementioned molecular patterns will also be evaluated in light of the type of P2Y12 inhibitor implemented (ticagrelor or prasugrel) to identify variations in response (secondary objective).
Out objective is to identify the mechanisms that promote hepatic and myocardial fibrosis, and collateral vessel formation in patients with complex congenital heart disease and Fontan circulation.
Previous monocentric experiences have already highlighted the role of preoperative cardiac imaging, in particular of cardiac magnetic resonance (CMR) and tomography (CT), in improving the ablation results of scar-related ventricular tachycardia (VT). A better characterization of scar obtained with high quality CMR images and post processing data with creation of maps exploring the heart in concentric layers from the endocardium to the epicardium could allow a personalized and more precise approach to this pathology. Aim of the study - Evaluating the feasibility and possible benefit of CMR-guided ablative approach (group 1: ablation of the "anatomical" channels of heterogeneous tissue within the scar) compared to CMR-aided approach (group 2: ablation of the "electrical" conduction channels within the scar) and standard approach (group 3: ablation guided by an electro-anatomical system without the aid of CMR) in a multi-center Tuscan study. What would add the project to what we know - The achievement of the objectives by the project would allow to propose a personalized ablation on the basis of the scar characterization and would allow a better efficacy, efficiency of the procedure and probably also a safer treatment
