Coronary artery stenting has become the most important nonsurgical treatment for coronary artery disease. However, in-stent restenosis occurs at a relatively high rate and this problem has led to the routine use of invasive angiography for assessing stent patency. Although cor‐ onary angiography is the clinical gold standard and it is a very effective diagnostic tool for detecting such in-stent...

UNLABELLED In this case we herein report a dangerous complication from primary percutaneous coronary intervention, where an unnoticed loop of the guidewire was inadvertently made around the stent during provisional stenting. Since the guidewire and the stent were entangled, efforts to retrieve the guidewire only exacerbated the problem by compressing the stent like an accordion. We review those...

The development of stent has been a major advance in the treatment of obstructive coronary artery disease since the introduction of balloon angioplasty. Subsequently, neointimal hyperplasia within the stent leading to in-stent restenosis emerged as a major obstacle in long-term success of percutaneous coronary intervention. Recent introduction of drug-eluting stents is a major breakthrough to t...

Entrapment of catheter components during cardiac interventions is rare but can cause life-threatening complications and sometimes requires emergency surgical treatment. This case study describes a 52-year-old male who had unstable angina pectoris and underwent stent insertion into the left circumflex artery. Unfortunately, the coronary stent and the balloon catheter were trapped while crossing ...

INTRODUCTION AND OBJECTIVES The aim was to determine whether prior coronary stent implantation affects postoperative outcomes in patients undergoing coronary artery bypass grafting. METHODS Between January 2005 and April 2008, a retrospective analysis was carried out to evaluate the effect of prior coronary stent implantation in patients undergoing off-pump coronary surgery on the incidence o...

INTRODUCTION Systemic embolisation of stents represents a rare complication of coronary interventions. REPORT The case of a patient with peripheral embolisation of a coronary stent while undergoing a coronary procedure for an ischaemic event is reported. The stent lodged at a previously created iatrogenic fistula joining the profunda femoral artery and the common femoral vein. An endovascular...

Coronary artery aneurysm is an uncommon disease. When it is associated with significantly obstructive coronary artery disease, percutaneous transluminal coronary angioplasty with graft-coated stent implantation usually provides favorable results. Non-coated stents may have the potential risk of thromboembolism. We present a patient with unstable angina who received elective balloon angioplasty ...

We report herein the optical coherence tomography (OCT) and stent boost imaging guided bioresorbable vascular scaffold (BVS) implantation for right coronary artery (RCA) chronic total occlusion (CTO) lesion. The gold standard for evaluating BVS expansion after percutaneous coronary intervention is OCT. However, stent boost imaging is a new technique that improves fluoroscopy-based assessments o...

T HE MANAGEMENT OF PATIENTS WHO UNdergo coronary artery stent implantation and subsequently require noncardiac surgery is a real and challenging clinical problem. In 2008, more than 800 000 percutaneous coronary procedures were performed in the United States, with coronary stents implanted in over 96% of cases. Approximately 5% of patients undergo noncardiac surgery in the 12 months following c...
