Dual guide catheter technique for treating native coronary artery lesions through tortuous internal mammary grafts: separating equipment delivery from target lesion visualization.

Christopher Lichtenwalter, Subhash Banerjee, Emmanouil S. Brilakis

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 …
