In percutaneous coronary intervention for chronic total occlusion (CTO), the retrograde approach is an advanced technique. To improve the long‐term patency rate, stent implantation is necessary for CTO, however, antegrade stent delivery to the lesion is contraindicated in cases where there is an anomalous origin or deviation of the coronary artery, or the edge of a previously implanted stent extends into the aorta. We report a successful case of retrograde stent implantation via a septal perforator in a patient with marked deviation of the RCA origin. In this case, antegrade stent implantation was difficult because antegrade catheter insertion carried a risk of crush deformation of an ostial stent. © 2009 Wiley‐Liss, Inc.
