Abstract
The technique of rotational angiography (RA) was developed to enhance the number of images available to more fully assess the complex coronary vasculature from numerous projections and has been found to be clinically useful in decreasing contrast dose, radiation exposure, and overall procedure time with an adequate safety profile and comparable image content to SA. 4‐6 Dual-axis rotational coronary angiography (DARCA) was developed as an innovative adaptation of RA in which rotation occurs in the left anterior oblique (LAO)/right anterior oblique (RAO) and cranial/caudal orientations during 1 cine acquisition to obtain images in a trajectory specifically designed to reduce vessel foreshortening. We present 2 cases demonstrating the novel application of DARCA in optimally defining the significance of specific coronary artery lesions while reducing contrast, radiation exposure,and providingsuperiorlesion imaging.
