Cardiac Assessment for Thrombus Detection in the Heart Using Advanced Imaging (MRI, CT) in ESUS With Left Ventricular Disease

The CATCH ME study is a prospective, multicenter, observational, no-profit study aimed at improving embolic risk stratification in patients with embolic stroke of undetermined source (ESUS), particularly in those with left ventricular disease (LVD). LVD is defined by a mildly to moderately reduced ejection fraction (30-49%), left ventricular wall motion abnormalities (hypo/akinesia), ventricular dilation, cardiomyopathies, and other related conditions. In these patients, the intermittent formation of intracardiac thrombi within the ventricle, often undetectable by standard diagnostic evaluation such as transthoracic echocardiography (TTE) alone, may serve as an unrecognized embolic source. However, in clinical practice, such patients are frequently discharged on antiplatelet therapy alone, without adequate thromboembolic risk stratification, thus leaving them at a high risk of ischemic recurrence. This study aims to assess the additional diagnostic value of advanced cardiac imaging - Cardiac Magnetic Resonance Imaging (CMRI) and/or Cardiac Computed Tomography (CCT) - in detecting intracardiac thrombi not identified by TTE in patients with ESUS and LVD.
