Accumulating data on the safety and efficacy of first-generation drug-eluting stents (DES) show a favorable risk/benefit profile compared with bare-metal stents (BMS). A recently reported collaborative network meta-analysis including >18,000 patients in 38 randomized trials along with other recent meta-analyses indicate that the use of DES versus BMS is associated ...

Within labeled indications, drug-eluting stents (DES) are as safe as bare-metal stents (BMS). Data from key randomized, controlled trials comparing paclitaxel-eluting stents with BMS or sirolimus-eluting stents with BMS show no difference in risk of death/myocardial infarction or stent thrombosis using uniform definitions of stent thrombosis. However, these trials and ...

A well-publicized presentation at the 2006 meeting of the World Congress of Cardiology (WCC) raised questions about the safety of drug-eluting stents (DES), leading to a rapid change in clinical practices for patients undergoing percutaneous coronary interventions. Subsequent independent analyses, which included patient-level data, found that DES, despite a small ...

Entrapment and fracture of coronary angioplasty hardware are rare complications of percutaneous coronary interventions for which cardiac surgery is sometimes required. We report a case of guidewire entrapment during stenting of the left anterior descending coronary artery (LAD) that required surgical removal. Although a piece of guidewire remained entrapped inside ...

AIMS: Recent evidence suggest that coronary bifurcation lesions might be treated by DES using "the mini-crush technique" with low rate of MACE and restenosis both at main and side branches. However, the treatment of a coronary trifurcation lesion is more problematic. Here we assess the feasibility of the "mini-crush technique" ...

Percutaneous branch pulmonary artery (PA) stenting can be challenging, especially in patients with stenosis of the right ventricular (RV) outflow tract or tortuous PA branches. In these cases, a hybrid procedure deploying PA stent(s) during cardiac surgery provides an alternative to relieve branch PA stenosis. The Mayo Clinic Congenital Cardiac ...

A neonate weighing 2.8 kilograms underwent the staged hybrid procedure for palliation of hypoplastic left heart syndrome. Within 6 hours following placement of a stent to retain patency of the interatrial communication, the infant developed second degree atrioventricular block, which resolved within 24 hours. Four days later, the patient developed ...

Although balloon angioplasty has been accepted as the safe and effective initial treatment to manage hepatic venous outflow abnormalities, it may induce rupture of the fresh anastomosis but also may be ineffective to eliminate various etiologies of venous outflow abnormalities in the early post-transplant period. Therefore, we performed primary stent ...

Cardiac transplantation is a well defined therapy for end stage heart failure. After the first year of transplantation, allograft coronary artery disease (ACAD) is the second main cause of death. The ACAD is defined as a diffuse process affecting the entire length of epicardial vessels. Once ACAD has been established, ...

The optimal treatment for renal artery in-stent restenosis (ISR) is not well established. Reintervention with different strategies including balloon angioplasty, cutting-balloon angioplasty, additional stenting with bare-metal, drug-eluting or covered stents and brachytherapy are effective in achieving immediate angiographic success. However, recurrent ISR rates are high irrespective of treatment strategy. We ...

Stent thrombosis is a rare complication following stent implantation; if it occurs, however, it is associated with a high morbidity and mortality. Despite reduced rates of restenosis, drug-eluting stents (DES) have not reduced the incidence of stent thrombosis as compared with bare-metal stents (BMS). Patient-, lesion-, and procedure-related factors as ...
Sangiorgi Giuseppe - - 2008
BACKGROUND: Sirolimus-eluting stents (SES) prevent restenosis and repeat percutaneous coronary intervention (PCI), but safety data in unselected patients are limited, especially for intermediate-term follow-up. METHODS: All patients undergoing SES implantation at 4 Italian centers were enrolled into a dedicated database. Baseline, procedural, and outcome data at discharge and at follow-up ...

Acute stroke intervention is rapidly evolving. New technologies are improving device deliverability and rates of recanalization. We describe 2 cases of acute middle cerebral artery occlusions wherein Wingspan stents could not be delivered to the occlusive site because of excessive vascular tortuosity. Merci thrombectomy was also unsuccessful. Revascularization was only ...

OBJECTIVE: To evaluate a new technique of precise ostial coronary stenting without relying solely on angiography. BACKGROUND: Precise stent positioning at ostial coronary stenosis is difficult because angiography may not be able to profile the coronary ostium, due to vessel overlap and/or foreshortening. This problem is compounded by bobbing or ...

Direct stenting without predilatation is a well-defined, feasible method with bare metal stents. Direct stenting has also been shown to be safe and feasible with drug-eluting stents, however, there is much less evidence with this type of device when compared with bare metal stents. Three hundred and sixty-four coronary lesions ...

Drug-eluting stents (DES) became the default strategy for percutaneous revascularization due to their improved intermediate-term outcomes when compared with bare-metal stents (BMS) in the pivotal randomized, controlled trials. The excellent results of DES in on-label or US FDA-approved indications led to extrapolation of the results to more complex situations that ...

Self-expanding metal, as well as silicon, stents have long been available for use in the airway. Metal stents can be placed using a flexible bronchoscope and are less readily removed. Silicone stents require rigid bronchoscopy and general anesthesia for placement but are removable. Both technologies are prone to complications on ...
Biondi-Zoccai Giuseppe Gl - - 2008
BACKGROUND: Drug-coated (i.e., drug-eluting) stents (DES) are frequently used nowadays in the treatment of coronary artery disease given their superior antirestenotic effect and clear benefits in terms of reduction of repeat revascularizations and major adverse cardiac events. However, a number of safety concerns have been raised on DES. OBJECTIVE: To ...

Vascular access for hemodialysis remains a challenge for nephrologists, vascular surgeons, and interventional radiologists alike. Arteriovenous fistula and synthetic grafts remain the access of choice for long-term hemodialysis; however, they are subject to complications from infection and repeated needle cannulation. Pseudoaneurysms are an increasingly recognized adverse event. At present, there ...
Kelbaek Henning - - 2008
BACKGROUND: Implantation of drug-eluting stents (DES) limits the rate of coronary restenosis in most patients with coronary artery disease, but data are scarce with regard to their use in patients with ST-segment-elevation myocardial infarction and in connection with distal protection of the microvascular perfusion during primary percutaneous coronary intervention. METHODS ...
