Fig. 1From: Three-dimensional thoracic aorta principal strain analysis from routine ECG-gated computerized tomography: feasibility in patients undergoing transcatheter aortic valve replacementThoracic aorta 3-dimensional peak principal strain amplitude (PPSA) calculations using ECG-gated CTA from two patients with severe aortic valve stenosis awaiting transcatheter aortic valve replacement. These images demonstrate regional heterogeneity of 3D aortic PPSA with greater amplitude strain along the ascending aorta greater curvature (arrow, consistent with AS jet directionality) and relatively reduced strain amplitude in the aortic arch and descending aorta segments. The two patients demonstrate consistent regional strain patternsBack to article page
