Repetitive stent fractures with diffuse coronary artery microaneurysm formation--sirolimus eluting stent hypersensitivity?
While drug eluting stents (DES) are being more widely used in ever more patients receiving DES each day, some new complications may be emerging. Stent fractures and hypersensitivity reactions to stents are among recognized complications that can lead to therapeutic dead end from the interventional cardiologist's point of view. We present a case in which we reached therapeutic dead end with a sirolimus eluting stent, i.e. repetitive stent fractures with diffuse microaneurysms along the implanted DES, possibly due to hypersensitivity reaction to parts of the stent.
