background: the biolimus-eluting stent (bes), with a biodegradable polymer, has not been previously compared with the everolimus-eluting stent (ees), as a second-generation drug-eluting stent (des).we sought to compare the 1-year outcome between the promus ™ stent (ees type) and the biomatrix ™ stent (bes type). methods: from march 2008 to september 2011, all patients treated with the promus™ s...

Background: This study assessed the application value of 64-slice spiral computed tomography angiography (CTA) in a follow-up evaluation of patients receiving coronary stent implantation. Materials and Methods: A total of 468 patients who underwent percutaneous coronary intervention (PCI) at our hospital between January 2013 and October 2016 were selected for this study. Coronary angiography an...

the invention of the drug-eluting stent (des) has brought about revolutionary changes in the field of interventional cardiology. in the des era, in-stent restenosis has declined but new issues such as stent thrombosis have emerged. one of the emerging paradigms in the des era is stent fracture. there are reports about stent fracture leading to in-stent restenosis or stent thrombosis. most of th...

Background: Anatomically myocardial bridging (MB) consists of either superficial myocardial fibers that traverse over the LAD or deep fibers that encircle the coronary artery. In this study, we present a patient with myocardial bridging, who was primarily diagnosed with coronary artery disease which did not properly respond to full-dose medical treatment but benefited from coronary artery bypas...

Here, we present a case of 56-year-old man with acute myocardial infarction. The patient underwent percutaneous coronary intervention (PCI) at the left main bifurcation and mid-left anterior descending artery using drugeluting stents. Four months after PCI, was readmitted for cardiac arrest. Coronary angiography (CAG) revealed stent thrombosis in main-toproximal in-stent restenosis circumflex a...

Coronary stent dislodgement is a rare and serious complication of percutaneous coronary intervention and is associated with major adverse cardiac events. Successful retrieval of the stent is recommended in this situation because it is important for the prognosis. Recently, a patient was referred to our hospital with a dislodged coronary stent. When attempting to percutaneously extract the dislo...

A 72-year-old man with a heavily calcified coronary lesion underwent percutaneous coronary intervention (PCI) using a third-generation drug-eluting stent (DES) with thin stent struts. Two months after the PCI, in-stent restenosis due to stent recoil (SR) occurred. An intravascular ultrasound (IVUS) revealed deformed stent struts and heavily calcified coronary plaque. The SR probably occurred du...

Introduction: This study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. Materials and Methods: This interventional study was conducted on 39 patients with coronary artery lesions, in whom Zotarolimus-eluting stents (N=20), Paclitaxel-eluting stents (N=11) and other stents (N=8) were deployed four tim...

AIM To compare polytetrafluoroethylene stent graft (PTFE) with sirolimus and bare metal stents in reducing in-stent restenosis in native coronary vessels in patients with acute coronary syndrome. METHODS The study included patients who underwent stent implantation in acute coronary syndrome from January 2003 to May 2004. The patients (n=119) were randomized either to stent graft group (n=40),...
