BACKGROUND: The goal of carotid artery stenting (CAS) is to decrease the stroke risk in patients with carotid stenosis. This procedure carries an immediate risk of stroke and death and many patients do not benefit from it, especially asymptomatic patients. Patient selection for carotid procedure who benefit from procedure and who is the procedure hazardous for is important. Remote ischemic stroke is known risk factor for stroke reccurence during surgery. The aim of our study was to determine the periprocedural complication risk (within 30 days after CAS) associated with carotid stenting (stroke, death) between patients with remote pre- procedural ischemic stroke and without it; to analyse periprocedural risk in other specific patient subgroups treated with CAS and to determine the impact of observed variables on all- cause mortality during long-term follow-up...

The aim of this study was to address 7-year clinical outcomes and impact of prolonged dual antiplatelet therapy (DAPT) after coronary stenting in hemodialysis patients. Our study included 123 consecutive hemodialysis patients who had undergone percutaneous coronary intervention with a drug-eluting stent (DES) or bare-metal stent (BMS) (DES: 64, BMS: 59) in our institution. We compared long-term clinical outcomes following DES with BMS implantation as well as clinical outcomes in patients on DAPT for ≥1 year (DAPT on group, 89) with those on DAPT for <1 year (DAPT off group, 34)...

An 11-year-old boy presented with easy fatigability, multiple xanthomas, and absent pedal pulsations. Laboratory workup showed severe hypercholesterolaemia and non-invasive imaging revealed 'normally functioning' bicuspid aortic valve and tight aortic coarctation. Coronary angiography showed severe right coronary artery (RCA) stenosis. Medical treatment resulted in significant improvement of dyslipidaemia. We successfully performed balloon dilation and stenting of his coarctation, as well as percutaneous coronary intervention for RCA lesion...

BACKGROUND: Epicardial adipose tissue (EAT) is significantly associated with the formation and composition of coronary atherosclerotic plaque, cardiac events and the clinical prognosis of coronary heart disease. But, whether increased EAT deposition may affect the incidence of in-stent restenosis (ISR) is currently unclear. This study used coronary computed tomography angiography (CCTA) as a mean to investigate whether increased EAT volume was associated with ISR. METHODS: A total of 364 patients who underwent 64-slice CCTA examination for the evaluation of suspected coronary artery disease, and subsequently underwent percutaneous coronary intervention (PCI) for the first time, and then accepted coronary angiography (CA) follow-up for ISR examination in one year, were retrospectively included in this study...

BACKGROUND: Current guidelines suggest that coronary artery bypass grafting (CABG) should be the preferred revascularization method for unprotected left main coronary artery stenosis. In light of evidence from recent randomized trials, we assessed whether percutaneous coronary intervention (PCI) using drug-eluting stents is as safe and effective as CABG for the treatment of unprotected left main coronary artery disease. METHODS AND RESULTS: Digital databases and manual searches were performed for randomized trials comparing PCI and CABG for unprotected left main coronary artery stenosis...

The long-term outcomes of patients who underwent paclitaxel-coated balloon (PCB) angioplasty for drug-eluting stent restenosis (DES-ISR) remain unclear. We investigated the 5-year safety and efficacy outcomes of PCB angioplasty for DES-ISR. The study included 185 patients with 216 DES-ISR lesions who underwent PCB angioplasty from September 2008 to December 2010. Two serial angiographic follow-ups were routinely scheduled at 6 and 18 months after the index procedure. Five-year clinical outcomes were investigated...

Percutaneous coronary revascularization strategies have gradually progressed over a period of last few decades. The advent of newer generation drug-eluting stents has significantly improved the outcomes of Percutaneous Coronary Intervention (PCI) by substantially reducing in-stent restenosis and stent thrombosis. However, vascular inflammation, restenosis, thrombosis, and neoatherosclerosis due to the permanent presence of a metallic foreign body within the artery limit their usage in complex Coronary Artery Disease (CAD)...

OBJECTIVES: The aim of this study was to identify histological features that correlate with terms commonly used to describe optical coherence tomographic (OCT) and optical frequency-domain imaging (OFDI) images of stented vessels, by means of a histopathological validation study using stented human coronary arteries. BACKGROUND: OCT imaging and OFDI are used to evaluate vascular responses to stent implantation. Descriptive terms such as "peristrut low attenuation" and "heterogeneous" have been used to describe neointimal characteristics that may have clinical relevance...

OBJECTIVE: With the demonstrated benefit of an early-invasive strategy for STEMI and VF/VT arrest patients, there is interest in assessing the potential benefit of early angiography for non-shockable (PEA/Asystole) arrest patients. We hypothesized that in cardiac arrest patients who obtain return of spontaneous circulation (ROSC) after a non-shockable initial rhythm and do not have STEMI the incidence of coronary intervention would be clinically insignificant (<5%). METHODS: Retrospective multicenter US clinical registry study of post-cardiac arrest patients at 18 hospitals between 1/00 and 5/14...

We assessed long-term outcomes after left main coronary artery (LMCA) stenting based on lesion types and stenting strategies. In the Assessing Optimal percutaneous coronary Intervention for Left Main Coronary Artery stenting registry, we evaluated 1,607 consecutive patients undergoing stent implantation for unprotected LMCA lesions (bifurcation lesions: n = 1318 and nonbifurcation lesions: n = 289). Among the bifurcation lesions, 1,281 lesions were treated with stenting across the bifurcation (bifurcation 1-stent strategy: n = 999 or bifurcation 2-stent strategy: n = 282)...

BACKGROUND: Drug-eluting stent (DES) -induced coronary vasospasm is a well known phenomenon after stent implantation; however, the extent of this risk is still unknown. We report a case in which DES-induced severe coronary vasospasm was clinically suspected as a cause of subacute stent thrombosis (ST). CASE PRESENTATION: A 67-year-old man came to our hospital due to chest pain with mild exercise. He was diagnosed with effort angina by coronary angiography and underwent DES implantation in the mid-left ascending artery (LAD) after the administration of dual anti-platelet therapy...

Arjun Majithia, Deepak L Bhatt
Dual antiplatelet therapy (DAPT) is an essential component of treatment in patients with coronary artery disease treated with percutaneous coronary intervention (PCI). Recommendations for duration of DAPT after PCI should consider patient-specific risk, clinical presentation, stent characteristics, and procedural factors. Prolonged DAPT results in a reduction of stent thrombosis (ST) and myocardial infarction (MI) at the cost of increased bleeding. Studies of shorter-duration DAPT demonstrate similar mortality, MI, ST, and less bleeding when compared with longer DAPT duration...

Bioresorbable vascular scaffold (BVS) is a novel technology designed to overcome the long-term limitations of permanent metallic stent implantation in percutaneous coronary intervention. However, little is known about the development of coronary aneurysms after the use of BVSs, and additional experience is needed to establish the entire spectrum of complications related to the use of these emerging materials. We hereby report an unusual case of early multiple coronary artery micro aneurysms formation after BVS implantation...
