Official Title

Personalizing The Risk Of Stroke And Silent Brain Infarct In Cardiovascular Disease

Brief Summary

      This study is designed to quantify the ventricular stasis in patients with different forms of
      cardiomyopathy and at risk of stroke (ischemic, non-ischemic dilated cardiomyopathy and
      hypertrophic cardiomyopathy) by post-processing of 2D color Doppler echocardiography and
      phase contrast-magnetic resonance images in order to establish the relationship between
      quantitative variables of intraventricular stasis and the prevalence of silent embolic events
      and/or intraventricular mural thrombosis.
    

Detailed Description

      Cardioembolic stroke is a major source of mortality and disability worldwide and blood stasis
      inside the heart is the main risk factor for developing intracardiac thrombosis. We have
      recently developed and patented a quantitative image-based method to map blood stasis within
      the cardiac chambers. The method is suitable for any medical imaging modality that provides
      time-resolved flow maps inside the heart (magnetic resonance, echocardiography, or
      computational-fluid-dynamic processing from anatomical CT images). The objective of the
      present project is to validate this certified technology in a multicentric cross-sectional
      clinical trial of 258 patients with different forms of cardiomyopathy with high-risk of
      stroke.

      We will include patients with ischemic, non-ischemic dilated cardiomyopathy and hypertrophic
      cardiomyopathy in sinus rhythm and an echocardiogram, cardiac and cerebral MRI will be
      performed. Our objective is to quantify the ventricular stasis by post-processing of 2D color
      Doppler echocardiography and phase contrast-magnetic resonance images in order to establish
      the relationship between quantifiable intraventricular stasis variables and the prevalence of
      silent brain infarctions (SBIs) and intracavitary thrombosis determined by magnetic resonance
      (MRI).
