Surgical creation of new anastomosis has been proposed as the preferred treatment for perianastomotic stenoses of fistulae. Seventy-three consecutive patients undergoing 112 PTA procedures for the treatment of perianastomotic lesions were studied.

Abstract

Fewer than half of patients with ST-elevation acute myocardial infarction (STEMI) are treated within guideline-recommended door-to-balloon times; however, little information is available about the approaches used by hospitals that have been successful in improving door-to-balloon times to meet guidelines. We sought to characterize experiences of hospitals with outstanding improvement in door-to-balloon time during 1999-2002.

Abstract

Restenosis within bare-metal stents is often treated with repeat percutaneous coronary intervention, although subsequent recurrence rates are high, with vascular brachytherapy (VBT) affording the best results. The effectiveness of drug-eluting stents in this setting has not been established. OBJECTIVE: To investigate the safety and efficacy of the polymer-based, slow-release paclitaxel-eluting stent in patients with restenotic lesions after prior stent implantation in native coronary arteries.

Although vascular brachytherapy is the only approved therapy for restenosis following bare-metal stent implantation, drug-eluting stents are now being used. Data on the relative merits of each are limited. OBJECTIVE: To determine the safety and efficacy of the sirolimus-eluting stent compared with vascular brachytherapy for the treatment of patients with restenosis within a bare-metal stent. DESIGN, SETTING, AND PATIENTS: Prospective, multicenter, randomized trial of 384 patients with in-stent restenosis who were enrolled between February 2003 and July 2004 at 26 academic and community medical centers. Data presented represent all follow-up as of June 30, 2005.

Pubmed abstract

To assess the outcome of stenting in patients with severe left ventricular dysfunction, 149 consecutive patients undergoing coronary stenting with an ejection fraction less than or equal to 40% (mean 35 +/- 10%) were analyzed. Angiographic and clinical success were achieved in all patients.

Abstract

In order to study the possible association of clinical risk factors on the incidence of restenosis; clinical predictors were determined in 98 patients (81 males and 17 females) who all undergone follow-up coronary angiography within 8.2 months after PCI.

Abstract

To assess the long-term patency and clinical success of subintimal angioplasty in patients with limb-threatening ischemia. METHODS: From 1999 through 2004, 29 patients with superficial femoral artery (SFA) or popliteal artery occlusion and rest pain or tissue loss underwent subintimal angioplasty. Patients had subintimal wire placement followed by percutaneous transluminal angioplasty and stent placement.

The purpose of the current study was to evaluate the changes in incidence, clinical characteristics, and indications for emergency coronary artery bypass grafting (CABG) in patients undergoing percutaneous coronary intervention (PCI) from 1979 to 2003.

The backup force of a guiding catheter is important for successful percutaneous coronary intervention (PCI), however, no theory has been proposed thus far regarding the factors involved in its generation.

METHODS AND RESULTS: The backup force of guiding catheters was measured in an arterial tree model. In vitro modeling showed that larger-sized guiding catheters had greater backup force (8 Fr > 7 Fr > 6 Fr). Comparing the backup force between transfemoral (TFI) and transradial interventions (TRI), it was found to be 60% greater in TFI with a Judkins L (JL) catheter, and 8% greater in TFI with a backup (EBU/XB) type catheter.

Abstract

The aim of the present study was to investigate the prognostic significance of time-delay to peak creatine kinase (CK) after successful direct percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI).

To test the feasibility of self-expanding drug-coated nitinol stents for prevention of restenosis in an animal model. Stent implantation in the carotid artery (CA) has been shown to be feasible for treatment of CA stenosis. Even though the restenosis rate in CA is reported to be lower than in the coronary and peripheral arteries, problems may arise with increasing numbers of treated patients and lengthier follow-up.

Restenosis requiring reintervention limits the long-term success after coronary stent implantation. Thiazolidinediones, like pioglitazone or rosiglitazone, are oral antidiabetic drugs with additional antirestenotic properties. In a randomized, placebo-controlled, double-blind trial, we examined the effect of 6-month pioglitazone therapy on neointima volume after coronary stenting in nondiabetic coronary artery disease patients.

Medline abstract

An American College of Cardiology/American Heart Association (ACC/AHA) Task Force periodically revises and publishes guidelines with evidence-based recommendations for appropriate use of percutaneous coronary intervention (PCI). Some studies have suggested that closer adherence to guidelines can reduce variations in care, can improve quality, and may ultimately result in better outcomes, but this finding is incompletely understood. Guidelines themselves must change to be responsive to continuously evolving clinical practice. Authors goal here was to investigate whether any relationship existed between the most recent ACC/AHA recommended indications for PCI and short term in-hospital outcomes.

Abstract

This study aimed to investigate percutaneous coronary intervention patients’ preferences regarding information provision and to identify patient characteristics associated with specific preferences.
