Dislodgement of a coronary stent in a coronary artery is a dreaded complication that occurs in a minority of patients. Factors that can increase the chances of stent detachment from the balloon catheter within a coronary artery can include tortuosity…
Vertebral artery (VA) stenting is an established method to treat occlusive disease in that artery. Available data indicate that it is a low-risk procedure with excellent periprocedural and long-term follow-up results.1–6 In most cases, the stenosis i…
The use of drug-eluting stents (DES) has become popular because of their favorable effects on clinical and angiographic outcomes.1–5 However, most clinical results have been reported on simple de novo lesions. In real-world practice, more complex les…

Access to severely angulated coronary vessels and branches can represent a challenge, even for experienced interventionalists, and despite the use of modern highly steerable guidewires. Percutaneous treatment of such lesions also confers a higher cha…
Polymer-coated stents eluting either rapamycin or paclitaxel, drugs that prevent entry of VSMCs into the proliferative cell cycle and inhibit neointimal formation following arterial injury, have dramatically decreased the risk of restenosis following…
