Figure 8: (Reproduced with permission) Normal right coronary artery arising from the right anterior sinus in (a) and the three-dimensional reconstructed image of the same in (b); (c) In left anterior oblique view4, the outflow tract of the left ventricle and aorta may schematically be regarded as a cylinder with bulge in the middle owing to the presence of aortic sinuses. An imaginary line drawn at the upper edge of the bulge marks, the plane dividing the aortic sinuses from the ascending aorta. Another vertical line is drawn along the long axis of the ascending aorta intersecting the aortic sinus and aortoventricular planes perpendicularly. The origin of the aorta above the sinotubular plane; B: origin just below the ostium of the left coronary artery; C: Origin below the sinotubular plane between the midline and the left coronary artery; D: origin along the midline. The Judkins left 5.0 guide catheter and extra backup 3.5 catheter were most successful in engaging the type A and type B right coronary artery origin, respectively. Amplatzer left guide catheter was successful for most of the type C right coronary artery origin anomalies in their study
