Stent thrombosis is defined as thrombotic occlusion of a stent resulting in acute coronary syndrome (ACS). However, all thrombotic occlusions of stents might not result in ACS. The present case report describes silent, very late thrombotic occlusion of a drug-eluting stent that was confirmed from specimens removed by directional coronary atherectomy.

In-stent thrombosis is a rare but devastating complication of coronary stent implantation, occurring in 0.5% to 1.9% of patients with bare metal stents (BMS). The most frequent clinical manifestation of stent thrombosis is ST elevation myocardial infarction (STEMI) and 30 day mortality is 50%. In-stent thrombosis can present as acute (within 24 h), subacute (within 30 days), late or very late a...

Percutaneous coronary intervention with stenting is widely used for ischemic heart disease. Because stent loss, which occurs rarely during the procedure, might have dire consequences, such as bleeding, stent embolism, acute myocardial infarction, emergency coronary artery bypass graft, and death, appropriate treatment is needed as soon as stent loss occurs. We report three cases of stent loss w...

The importance of intravascular ultrasound (IVUS) as an adjunctive technology facilitating optimal coronary interventional procedural technique has become increasingly evident over the past decade. IVUS is currently appreciated as an invaluable tool enabling better assessment of reference vessel size and coronary lesion morphology, including gross plaque characteristics and lesion length. Accor...

Sixty-one-year-old male patient with diagnosis of myelodysplastic syndrome and unstable angina was submitted to coronary angiography and implant of stent. His Blood cell count revealed 40,000 platelets/mm3. Coronary angiography with previous platelet transfusion showed obstruction of 80% of the right coronary artery (RCA). Following the administration of clopidogrel, the patient was submitted t...

Coronary artery disease is the most important cause of mortality in patients with systemic lupus erythematous (SLE). After stenting for coronary artery disease in SLE patients similar to non-SLE patients, the risk of stent thrombosis is always present. Although there are reports of stent thrombosis in SLE patients, very late recurrent stent thrombosis is rare. We experienced a case of very late...

Although many patients with coronary artery disease are being treated by coronary stents, in-stent restenosis is the major limitation of percutaneous coronary stenting procedures. Most stents are made of stainless steel, and that, allergic reactions to nickel ions released from coronary stainless-steel stents may be one of the triggering mechanisms for in-stent restenosis. We aimed to evaluate ...

Coronary artery disease (CAD) is a common disease and has an impact in all over the word. With the development of life level and life style, the incident of morbidity and mortality largely increased [1]. Atherogenesis and the formation of thrombi are the main risk events. The application of percutaneous coronary intervention (PCI) released coronary artery disease and improved patients’ quality ...
