Fig. 1From: Computed tomography coronary angiography in patients without known coronary artery disease can demonstrate possible non-cardiovascular causes of non-acute retrosternal chest painDifferent kinds of computed tomography coronary angiography (CTCA) images showing examples of coronary diseases. a Transverse curved planar reformatted (CPR) image showing a non-calcified plaque in the mid-segment of the left anterior descending coronary artery (arrow), causing a significant (> 50%) stenosis. b CPR image along the left ventricle vertical long axis showing a 3-cm-long myocardial bridging (arrowheads) of the mid-distal third of the left anterior descending coronary artery. c Three-dimensional volume rendering image showing the origin from the left Valsalva sinus of the right coronary artery (arrow), which reaches the right atrium-ventricular path, coursing between the aorta root (Ao) and the pulmonary artery root (cut – PA) (malignant course)Back to article page
