Late Gadolinium Enhancement Patterns in Aortic Stenosis
Each panel shows short-axis (top) and corresponding long-axis (bottom) late gadolinium images from cardiac magnetic resonance scans. (A to C) Focal noninfarct late gadolinium enhancement typical of the replacement fibrosis seen in aortic stenosis. (D) Subendocardial late gadolinium enhancement in coronary artery territories, consistent with scar due to infarction rather than focal noninfarct fibrosis. Areas of infarction such as these should be excluded when calculating extracellular volume fraction. Red arrows indicate areas of late gadolinium enhancement.
