Background: Percutaneous coronary interventions of chronic total occlusion represent one of the most challenging issues in interventional cardiology. A Caucasian patient with dextrocardia presented with an in-stent chronic total occluded right coronary artery, a constellation which has not been described previously in the literature.
Case presentation: A 69-year-old man with pre-known situs inversus totalis and a long history of coronary artery disease with multiple interventions and stent-implantations presented to our department suffering from episodes of chest pain under exercise. A coronary angiogram showed a completely occluded right coronary artery in the area of a drug-eluting stent which had been implanted eight years before. We found collaterals from the left coronary artery system and signs of calcification, so the lesion was classified as chronic total occlusion and the recanalization using an antegrade wire escalation technique successfully performed.
Conclusion: This is the first reported case of an in-stent chronic total occlusion in situs inversus with dextrocardia. Our experience in this case demonstrates the feasibility of recanalization of in-stent chronic total occlusions even in the rare setting of this congenital cardiac malposition combined with severe coronary artery disease.
