Abstract:
Attempts to wire and stent a native coronary artery lesion through a tortuous internal mammary graft can result in graft occlusion, ischemia, and inability to visualize the distal lesion. We report three cases in which treatment of such lesions was successfully completed using two guiding catheters, one of which was used for lesion visualization and one for equipment delivery.
