Figure 1 Left Main Coronary Artery With a Course Between Aorta and Pulmonary Artery
Axial (A) and sagittal oblique (B) cross-section through the origin of the left coronary artery. The left coronary artery displays a tight stenosis (arrow) and follows a course between the aorta and pulmonary artery. (C) Corresponding invasive angiogram: selective catheterization of the left coronary ostium was not achieved. Selective right coronary angiography shows a dominant right coronary artery giving rise to a circumflex artery retrogradely filling the left anterior descending artery. Ao = aorta; LA = left atrium; LAD = left anterior descending coronary artery; LV = left ventricle, PA = pulmonary artery.
