Late multiple stent fractures following deployment of sirolimus-eluting stents for diffuse right coronary artery stenosis.

چکیده
We report a case of late multiple stent fractures following the deployment of sirolimus-eluting stents (SESs) for diffuse right coronary artery (RCA) stenosis. A 44-year-old male with hyperlipidemia was referred to our hospital for acute myocardial infarction (AMI). Percutaneous coronary intervention (PCI) was performed for total occlusion of the proximal segment of the RCA, and 5 SESs were consecutively implanted for long, diffuse stenotic lesions. A follow-up coronary angiography (CAG) performed 8 months later revealed strut fractures in the middle of all the stents, except the most proximal one. Multislice computed tomography confirmed the locations of the fractured struts inside of the stents.

Late incomplete lesion coverage following Cypher stent deployment for diffuse right coronary artery stenosis.
The availability of the only drug eluting stent currently approved in the USA has been limited, so that operators often resort to the deployment of multiple undersized stents and post-stenting high pressure inflations with larger balloons to achieve optimal lesion coverage and stent expansion. A case of stent fracture following percutaneous coronary intervention in which this strategy was used ...

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 si...

The root cause of coronary artery disease is atherosclerosis, ie, intraluminal narrowing (stenosis) of the arteries that supply blood to tissues of the heart. The introduction of the drug-eluting stent over the past decade has revolutionized the field of interventional cardiology. It is used extensively in clinical practice for the treatment of coronary artery disease. The first drug-eluting st...
