Drug-eluting stent implantation is an effective treatment for coronary artery disease, yet unexpected serious complications during stent implantation are possible. A 70-year-old man with unstable angina presented with a left main bifurcation lesion. Two drug-eluting stents were successfully deployed at the left main bifurcation lesion by the mini-crush technique under intravascular ultrasound g...

Significant advancements in percutaneous treatment of coronary artery disease have been achieved with the introduction of bare metal stents. They have two major drawbacks: acute/subacute stent thrombosis, successfully managed with antiplatelet therapy immediately after stent implantation; and in-stent restenosis, prevention of which has been achieved with the development of drug-eluting stents....

Sudden cardiac arrest associated with major spasm of three coronary arteries was observed about 10 hours after Taxus stent insertion in a three vessel lesion and was successfully treated by intracoronary glyceryl trinitrate infusion. This case illustrates a potential risk associated with drug eluting stent and alerts clinicians to the life threatening risk of spasm when stenting multiple vessel...

OBJECTIVES This study sought to investigate the long-term comparative efficacy and safety of paclitaxel-eluting balloon (PEB), paclitaxel-eluting stent (PES), or balloon angioplasty (BA) for the treatment of drug-eluting stent restenosis. BACKGROUND The optimal treatment of drug-eluting stent restenosis remains unknown. Although PEB has shown encouraging results, the long-term clinical effica...

This article focuses on optical coherence tomography findings in patients with late major cardiovascular events like myocardial infarction and/or stent thrombosis, following drug-eluting stent and bare-metal stent implantation. Uncovered stent struts and malapposition seem to play a critical role in drug-eluting stent-related late events. Neointimal features similar to native atherosclerosis ar...

Although stent fracture after implantation of a drug-eluting stent (DES) is a rare complication, it has been suggested to be a cause of restenosis. To date, most DES fractures have been associated with sirolimus-eluting stents. We describe here a case of a zotarolimus-eluting stent fracture after 8 months of stent placement in a calcified left anterior descending artery lesion in a patient unde...

BACKGROUND The efficacy of drug-eluting stents has been shown in randomized trials, but some controversy exists regarding which stent sirolimus-eluting or paclitaxel-eluting is more effective in unselected Turkish patients. Therefore, we investigated the clinical outcomes of patients who were treated with one type of these drug-eluting stents in the real world. METHODS We created a registry a...

Although the coronary arteries are uniformly exposed to systemic cardiovascular risk factors, atherosclerosis development has a non-random distribution, which follows local mechanical stresses including flow-related hemodynamic forces. Among these, wall shear stress plays an essential role and it represents major factor affecting distribution of in bifurcations. Furthermore, emerging body evide...
