Figure 4 Mild Compression of the Right Coronary Artery

Axial cross-section (maximum intensity projection) (A) and 3-dimensional reconstruction (B) showing a single coronary ostium from which both the right and left coronary arteries arise. There is mild compression of a long segment of the right coronary artery between the great arteries. The left coronary artery has a retroaortic loop with no stretching or compression. (C) Selective invasive angiogram of the right coronary artery: the proximal segment was classified as normal. Abbreviations as in Figure 1.
