Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a case of stent dislodgement in the ascending thoracic aorta. The stent was mechanically distorted in the left circumflex artery (LCX) while being delivered to the proximal LCX lesion. The balloon catheter was withdrawn, but the stent with the guide wire was remained in the ascending thoracic aor...
An 83-year-old man with acute myocardial infarction in 1998 was treated with a percutaneous coronary procedure, in which a 3.5 25mm Nir Royal stent (Boston Scientific, United States) was implanted in the proximal segment of the left anterior descending artery. He was admitted to our hospital for chest pain and acute pulmonary edema. The electrocardiogram showed an ST segment decrease in the ant...
BACKGROUND Drug-eluting stents reduce restenosis and reintervention rates but are complicated by stent thrombosis, which may be related to polymer coating. The NEVO sirolimus-eluting coronary stent (NEVO SES) is designed to improve long-term percutaneous coronary intervention safety by combining sirolimus release from reservoirs with bioabsorbable polymer to reduce spatial and temporal polymer ...
After coronary stent implantation, patients with acute coronary syndrome commonly take clopidogrel, and few patients develop severe thrombocytopenia related to clopidogrel. However, we found in our clinical practice that platelet counts of most patients decrease slightly after taking clopidogrel for 6 months. To address this discrepancy, we studied the change in platelet count after coronary st...
INTRODUCTION Aorto-ostial stenting remains one of the most demanding and risky types of angioplasty to perform. We report a case outlining a creative solution for the reengagement of a protruding aorto-ostial stent. CASE PRESENTATION A 69-year-old Caucasian man was admitted to our hospital's coronary care unit with progressive unstable angina five years following coronary artery bypass grafti...
BACKGROUND Heavy coronary artery calcification is responsible for stent underexpansion, which is associated with increased in-stent restenosis. Here we report a case in which optical coherence tomography (OCT) demonstrated that the metal component of an underexpanded stent previously implanted in a heavy calcified lesion had been completely removed after ablation with rotational atherectomy. ...
OBJECTIVES To evaluate initial and long term results of coronary perforation treatment with pericardial covered stent. BACKGROUND Iatrogenic coronary perforation is a rare life threatening complication of percutaneous coronary interventions (PCI) occurring in 0.1-0.8% of cases. Covered stents are the mainstay of therapy for coronary perforation. However, polytetrafluoroethylene covered stents...
coronary artery disease has dramatically altered the practice of coronary artery bypass grafting surgery. New complications caused by percutaneous coronary interventions (PCI) with the implantation of stents has emerged and affected the result when surgery is subsequently required. The stent was initially utilized for the treatment of complications associated with percutaneous coronary angiopla...
PURPOSE Serial change of the coronary flow velocity reserve was evaluated with fast velocity-encoded cine magnetic resonance imaging (MRI) for noninvasive detection of restenosis after coronary stent implantation. METHOD In total, 60 MRI flow studies were performed in 10 patients with coronary artery disease who undersvent elective successful stent implantation to the lesion in the proximal l...
BACKGROUND Coronary adventitia harbors a wide variety of components, such as inflammatory cells and vasa vasorum (VV). Adventitial VV initiates the development of coronary artery diseases as an outside-in supply route of inflammation. We have recently demonstrated that drug-eluting stent implantation causes the enhancement of VV formation, with extending to the stent edges in the porcine corona...
