What the trial is, and whether it could suit you
The new approach propose in this protocol is based on ultrafast ultrasound and remote palpation of tissue by ultrasonic radiation pressure. Ultrafast ultrasound of biological tissues is based on an innovative ultrasound imaging approach that can image very fast soft tissue events at a rate of several thousands of frames per second and provide quantitative mapping of the elasticity of the tissues. This current project aims is to focus on myocardial rigidity in diastole to better assess the function of the heart failure.
