Assessment of viability in myocardial disease continues to be of interest to clinicians. Principal strain patterns have been shown to change with ischemic injury, and can provide a sensitive index of viability. However, clinical use of principal orientations is extremely rare due to the existing noise in current measurements of angles. In this work, a reliable method of measuring principal strain angles was proposed. Consistency of the angles in the normal myocardium, combined with the results in the dysfunctional tissue in a porcine model, confirms the potential of principal strain orientations in assessment of viability.
