title: Case of dislodged stent lost in septal channel during stent delivery in complex chronic total occlusion of right coronary artery.
abstract: The retrograde approach is a recently introduced technique for percutaneous coronary intervention (PCI) of chronic total occlusions (CTO). To improve the long-term patency rate, stent implantation is necessary for CTO; however, antegrade stent delivery to the lesion is sometimes impossible in cases where there is a complex coronary anatomy. Although there have been some reports that retrograde stent delivery is useful in such cases, it is technically very challenging. We report a case of attempted stent deployment via the septal channel to treat a CTO, whereby the proximal right coronary artery was 360 degrees-looped and the stent dislodged in the septal channel.
