Figure 1

Feature tracking analysis in a healthy volunteer and a hypertrophic cardiomyopathy (HCM) patient. Feature tracking analysis in one healthy volunteer: left ventricular wall thickness (A) and regional radial strain of segments (B) in the mid-left ventricle were normal. (C) Shows regional radial strain curves of American Heart Association (AHA) segments. (D) Shows 3D model of radial strain. Feature tracking analysis in one HCM patient, where septal, anterior, and inferior wall (E) were thickened, and regional radial strain of thickened segments (F) were decreased. The purple curve shows the regional radial strain of the mid anteroseptal wall (G). Regional radial strain curves of AHA segments (H) in a 3D model show the regional radial strain of the mid anteroseptal wall (white arrow).
