Three-Dimensional, Right Ventricular Surface Strain Computation From Three Dimensional Echocardiographic Images From Patients With Pediatric Pulmonary Hypertension.

Components of 3DS strain agree with existing clinical strain measures, well classify normal -vs- PAH subjects, and suggest that strains change direction on the myocardial surface due to disease. This last finding is similar to that of myocardial fiber realignment in disease, but further work is needed to establish true associations.
