Progresses in echocardiography allow improved characterization of right-ventricular mechanical function in athletes: (A) two-dimensional speckle-tracking echocardiography from apical four-chamber visualization allows measuring right ventricle area and longitudinal strain limited to that cross section; (B) right ventricle geometry extracted from three-dimensional echocardiography; (C) the contraction can be separated in wall-specific contributions (credit: Kovács et al.⁸, under a Creative Commons Attribution 4.0 International License); (D) principal strain analysis allows to identify direction and entity of contraction.
