Coronary magnetic resonance angiographic images, using the Soap-Bubble reconstruction software tool, showing a common or juxtaposed origin of the left and right coronary arteries from the right sinus of Valsalva with a retroaortic course of the left main coronary artery (path no. 2). The right coronary artery has a normal course (single arrow). The left main coronary artery (single arrowhead) has a benign course, running posterior to the aortic root, then dividing normally into the left anterior descending (double arrows) and left circumflex (double arrowheads) coronary arteries. This view approximates a shallow left anterior oblique projection rotated 45° clockwise. Ao, aorta; LA, left atrium; PA, pulmonary artery; RA, right atrium.
