Abstract

This is a case report of left anterior descending coronary artery aneurysm (CAA), typical “zig-zag” phenomenon, that developed exactly within the segment of sirolimus drug-eluting stent (DES) implanted after percutaneous coronary intervention (PCI). The patient had a history of rheumatiod arthritis. We speculated the typical coronary artery aneurysms could be related to the vascular inflammatory reaction due to both of his rheumatoid arthritis and DES implantation. For this kind of patients with the history of rheumatoid arthritis, we could get some hint, DES implantation should be careful.
