Abstract

Three-dimensional (3D) wiring is one method for accurate guidewire control in chronic total occlusion (CTO) lesions during manipulation of CTO-specific stiff guidewires. However, the construction of a mental 3D image is difficult. We propose the idea of image patterns to allow immediate construction of 3D images from the two perpendicular angles of the X-ray system detector and report a case of CTO treated with 3D wiring.
