Insights from echocardiography, magnetic resonance imaging, and microcomputed tomography relative to the mid‐myocardial left ventricular echogenic zone

The anatomical substrate for the mid‐mural ventricular hyperechogenic zone remains uncertain, but it may represent no more than ultrasound reflected from cardiomyocytes orientated orthogonally to the ultrasonic beam. We sought to ascertain the relationship between the echogenic zone and the orientation of the cardiomyocytes.
