A Comparison of Global Longitudinal, Circumferential, and Radial Strain to Predict Outcomes after Cardiac Surgery

Journal of Cardiothoracic and Vascular Anesthesia, 2018
Objective: Myocardial strain measured by speckle-tracking echocardiography detects subtle regional and global left ventricular dysfunction. Myocardial strain is measured in the longitudinal, circumferential, and radial dimension; however, it is unclear ...

Segmental Analysis of Cardiac Short-Axis Views Using Lagrangian Radial and Circumferential Strain

Ultrasonic imaging (Print), 2015
Accurate description of myocardial deformation in the left ventricle is a three-dimensional problem, requiring three normal strain components along its natural axis, that is, longitudinal, radial, and circumferential strains.
