Figure 2From: Left ventricular strain and strain rate by 2D speckle tracking in chronic thromboembolic pulmonary hypertension before and after pulmonary thromboendarterectomy Left ventricular global circumferential strain (top left, dotted) and strain rate (top right, dotted) as well as radial strain (bottom left) and strain rate (bottom right) are displayed from a patient with CTEPH. The septal and posterior walls are outlined in red and purple respectively. The posterior wall radial strain is displayed post-PTE demonstrating the relative the hypokinesis of the septal segment (red).Back to article page
