The current randomized study aims to evaluate potential differences between the Edwards SAPIEN bioprosthesis and the Medtronic CoreValve® system with main focus on periprosthetic aortic regurgitation and additional focus on other clinical and…
Compare hemodynamic parameters and flow patterns of the stented Mitroflow bioprosthesis, stentless Freedom SOLO bioprosthesis,transcatheter Edwards Sapien bioprosthesis and healthy control subjects, measured with 4D flow MRI.
To demonstrate the efficacy of AdreView* imaging for appropriately guiding the decision of ICD implantation in a population of New York Heart Association (NYHA) class II and III Heart Failure (HF) patients with 25% * left ventricular ejection…
The primary objective is to investigate cerebral perfusion in rest and in response to moderate exercise (handgripping or light cycling) and a visual stimulus in patients with severe aortic valve stenosis prior and after surgical or transcatheter…
The aim of this project is (1) to examine reproducibility of measuring CO and LBF with PC-MRI during supine cycling (phase I) and (2) to measure CO and LBF during supine cycling in patients with CHF and healthy age-matched controls to investigate…
Primairy objectives:1.To investigate whether a non-invasive imaging guided strategy (either CTA or CMR) early in the diagnostic process reduces the number of patients with at least one ICA during the initial admission as compared to routine clinical…
We aim to i) describe flow patterns and flow-related dynamics in the ascending aorta of patients with aortic valve stenosis, ii) compare these flow parameters before and after surgical aortic valve replacement and iii) compare flow parameters with…
Primary Objective: To assess the analytical performance of the cardiac reader Secondary Objective(s): To assess the user friendliness of the device (handling, analytical speed).
Primary Objective: to compare the atrial contractility by means of echocardiography between patients receiving flecainide and vernakalant i.v. after conversion to sinus rhythmSecondary Objective(s): 2a. To compare the conversion rate of AF between…
Objectives: Part 1) To assess the prevalence of PA in general practice (part 1 of this study);Part 2) To describe differences of cardiorenovascular damage in newly diagnosed hypertensive patients with versus without PA (part 2 of this study);Part 3…
To assess whether the iFR is non-inferior to FFR when used to guide treamtent of coronary stenoses with PCI
The primary objective of this study is to validate that the reduced system dose setting with Xres4 translate into an overall procedure dose reduction. Procedure dose will be determined by the cumulative dose area product (DAP) value and the…
To compare the diagnostic value of CTA versus the standard work-up in terms of identifying patients with severe coronary artery disease (requiring revascularization), as well as the ability to safely discharge patients without coronary artery…
The overall aim of the study is to demonstrate that a comprehensive cardiac CT examination improves the diagnostic workup of stable chest pain in terms of accuracy, efficiency and costs. In concrete terms, the purpose of this randomized controlled…
The feasibility of direct-detection of fibrotic tissue will be assessed in patients with a healed myocardial infarction and in patients with cardiomyopathy using LGE as reference standard.
To study remodeling patterns of the left and right ventricle in patients with pulmonary arterial hypertension who underwent lung transplantation, using cardiac magnetic resonance imaging.
Demonstrate that with contemporary cardiac CT scan protocols good opacification of the coronary arteries can be achieved, that is similar to low-osmolar contrast media injected at the same iodine delivery rate. In addition, we will investigate the…
Quantify how many frail elderly aged over 65 years with reduced exercise tolerance and/or exercise induced dyspnoea have previously unrecognised COPD and heart failure.Quantify the difference in prevalence of unrecognised COPD and heart failure…
Demonstrate that the remote management system (Carelink, study group) reduces the time from device detected event onset to clinicaldecision for arrhythmias, cardiovascular disease progression,and system issues compared to patients receiving only in-…
Primary objectives:- Evaluation of the value of mBL as a diagnostic tool for bacterial endocarditis.- Evaluation of the value of mBL as a monitoring tool during treatment for bacterial endocarditis.- To obtain data on the kinetics of mBL related to…
