Figure 5 Example of successful placement of guidewire in a native coronary artery using a retrograde approach through a saphenous vein graft in a patient with coronary artery bypass surgery. In this case, the wire could be placed but the operator was unable to position a balloon in the target segment beyond the acute bend at the vein graft anastomosis. MAI = magnetic-assisted intervention.
