Intraventricular Stasis In Cardiovascular Disease

Status Recruiting

Clinical Trial 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.

Clinical Trial 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). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
