AIM: Stenosis in the unprotected left main coronary artery (ULMCA) is considered a standard indication for surgical revascularization. Some studies have demonstrated that stenting of the ULMCA is safe and feasible in selected patients. Drug eluting stents (DES) have been shown to be superior to bare metal stents (BMS) in ...

Stent thrombosis (ST) is a catastrophic complication that frequently presents as an acute myocardial infarction and/or death. The most recently accepted definition established by the Academic Research Consortium classifies ST as: early (occurring within 30 days), late (30 days to 1 year) or very late (after 1 year). Very late ...

The 2008 highlights in cardiovascular and thoracic anesthesia include the ultimate departure of aprotinin from clinical practice. However, a new antihypertensive drug, clevidipine, was approved for perioperative control of hypertension. There were also advances in pharmacologic myocardial conditioning with agents such as cyclosporine, sodium nitroprusside, and levosimendan. Furthermore, ischemic preconditioning ...

BACKGROUND: Several studies have shown that coronary stenting reduces the frequency of clinical and angiographic restenosis in patients with mild to moderate renal insufficiency. However, less is known about the long-term benefits of stent use in this population. This study was aimed to determine the impact of coronary stenting on ...

A stent fracture (SF) is one of the responsible factors for in-stent restenosis after a percutaneous coronary intervention. Factors that have an important role for a SF are vessel tortuosity, the presence of a right coronary artery lesion, overlapping stents, and the use of a drugeluting stent (DES) such as ...

Percutaneous coronary intervention with stent placement is widely used to achieve revascularization of the myocardium, especially in acute coronary syndrome. There is increasing number of reports published concerning stent thrombosis both in bare metal stents as in drug eluting stents. According to the newest ACC/AHA/SCAI 2007th guidelines, bare-metal stent or ...

We assessed the relationship of renal function and the clinical outcome in 2314 patients treated by drug-eluting stent (DES). At 24 months, the cumulative major adverse cardiac events (MACE) rate and the composite of death and myocardial infarction were higher in the patients with severe chronic kidney disease (CKD). Severe ...

Paclitaxel balloon coating has shown promising effects in inhibiting restenosis in initial clinical trials. The aim of the present study was to evaluate the influence of two critical features of drug-eluting balloon (DEB) application - inflation time and increased dose due to overlapping balloons. Fifty-six stainless steel stents were implanted ...

BACKGROUND: Despite rapid and complete recanalization of infarct-related artery with percutaneous coronary intervention, microvascular integrity is not often preserved. Several mechanical devices have been proposed to prevent distal embolization, but the impact of these devices on myocardial perfusion remains controversial. AIM: The aim of our study was to assess microvascular ...

The presence of a duodenal stent may hinder attempts at ERCP for treatment of malignant biliary obstruction. We describe 2 patients in whom endoscopic fenestration of indwelling duodenal stents with an argon plasma coagulator facilitated successful ERCP. Single-center retrospective case series. Tertiary-referral center. Both patients had unresectable biliary malignancy with ...

Endovascular intervention is considered first-line therapy for most superficial femoral artery (SFA) occlusive disease. Duplex ultrasound (DU) criteria for SFA in-stent stenosis and correlation with angiographic data remain poorly defined. This study evaluated SFA-specific DU criteria for the assessment of SFA in-stent stenosis. From May 2003 to May 2008, 330 ...

Prolonged dual-antiplatelet therapy with aspirin and clopidogrel is mandatory after drug-eluting stent implantation because of the potential increased risk of late stent thrombosis. The concern regarding prolonged antiplatelet therapy is the increased risk of bleeding. Gastrointestinal bleeding is the most common site of bleeding and presents a serious threat to ...

Although safety profiles of sirolimus-eluting stents do not seem to differ in short-to-medium term from those of bare-metal stents, late stent thrombosis after deployment of drug-eluting stents has emerged as a potential safety concern in the era of high-pressure stent implantation. Here, we describe the case of a patient with ...

Bare-metal stents are commonly used in the treatment of coronary artery disease. Stent thrombosis usually occurs within the first 48 hours after stent deployment. After a week, the incidence of thrombosis is low. Late stent thrombosis (after 30 days) is rarely seen; however, its clinical outcomes are severe 30-day mortality ...
Cola Clarissa - - 2009
Coronary stent thrombosis is a serious problem in the drug-eluting stent era. Despite aggressive antiplatelet therapy during and after percutaneous coronary intervention (PCI), the incidence of sub-acute stent thrombosis remains approximately 0.5%-2%, which may represent a catastrophic clinical situation. Both procedural factors and discontinuation of antiplatelet therapy are normally associated ...
Collet Jean-Philippe - - 2009
BACKGROUND: Clopidogrel and low-dose aspirin have become the mainstay oral antiplatelet regimen to prevent recurrent ischaemic events after acute coronary syndromes or stent placement. The frequent genetic functional variant 681 G>A (*2) of cytochrome P450 2C19 (CYP2C19) is an important contributor to the wide variability between individuals of the antiplatelet ...

PURPOSE: To compare a novel method, percent-infarct-mapping (PIM), with conventional delayed enhancement (DE) of contrast for accurate myocardial viability assessment. Contrary to signal intensity (SI), the longitudinal relaxation-rate enhancement (DeltaR1) is an intrinsic parameter linearly proportional to the concentration of contrast agent (CA). Determining DeltaR1 voxel-by-voxel, after administering an infarct-avid ...

OBJECTIVES: This study examines whether patient resistance to clopidogrel is associated with long-term thrombotic events after elective coronary drug-eluting stent (DES) implantation. METHODS: We prospectively enrolled 386 patients with stable angina who received elective percutaneous coronary intervention (PCI) with DES. Before the procedure, platelet reactivity was measured by light transmittance ...

OBJECTIVES: To describe a simple method of using a readily available portable ultrasound device to confirm distal stent placement for antegrade placed stents. Antegrade placement of internal double-J ureteral stents during open or laparoscopic pyeloplasty has become an alternative to retrograde placement but might be less reliable owing to the ...
Kukreja Neville - - 2009
Drug-eluting stents (DESs) have been shown to reduce the rate of repeat revascularization compared with bare-metal stents (BMSs) after multivessel percutaneous coronary intervention in carefully selected patients. However, the long-term safety and efficacy of DESs in patients with multivessel disease outside the setting of randomized trials was unknown. Therefore, all ...
Filion Kristian B - - 2009
Recent studies examining the effectiveness of drug-eluting stents (DES) have found that the use of DES is associated with a significant increase in the incidence of late stent thrombosis (LST). Previous cost-effectiveness analyses of DES have not accounted for the costs associated with LST. In this study, published research was ...
