PROVIDENCE:Prevention of Restenosis With Oral Rosiglitazone and the Vision Stent in Diabetics With Coronary Lesions
Description

We hypothesize that the combination of the thin-strut MULTI-LINK (i.e. VISION(tm) and/or MINI-VISION(tm)) stent and pharmacologic therapy with the oral PPAR-gamma agonist rosiglitazone will significantly reduce restenosis after intracoronary stenting in type 2 diabetic patients.

WITHDRAWN
Systemic Rapamycin (Sirolimus) to Prevent In-Stent Restenosis Following Pulmonary Artery Stent Placement
Description

This is a research study to assess whether an oral medication can benefit some patients being treated for peripheral pulmonary stenosis (PPS), which is narrowing of the blood vessels that send blood to the lungs (pulmonary arteries). In the cardiac catheterization laboratory, the investigators treat PPS by dilating the narrowed segments of pulmonary arteries using balloon catheters. Sometimes the investigators also place stents which are mesh tubes that help keep the narrowed vessel open. Some stents suffer from in-growth of tissue into the stents which causes recurrent obstructions inside the stent (i.e. making the opening inside the mesh tube narrow again), so called in-stent stenosis (ISS). The purpose of this study is to use a medication that is approved for use in children (for a different purpose) to decrease the amount of cell ingrowth inside the stents (i.e. decrease the problematic in-stent stenosis). The medication is called rapamycin, also known as sirolimus (trade name Rapamune). It has antiproliferative properties which means that it slows down cell division which the investigators believe cause the recurrent narrowing inside stents. Rapamycin is a medicine that can be taken by mouth as a liquid or pill or via a feeding tube. There will still be a need for interventions in the catheterization laboratory but the investigators hope that by taking this medicine some children would need fewer catheterizations in the future. Our early experiences with a few patients who have been treated with rapamycin due to in-stent stenosis in the pulmonary arteries suggest that it may be helpful. In this study, patients and families who are interested in possibly trying this new approach will be randomized to sirolimus or no sirolimus. The investigators will compare the developement of ISS over time between these groups, in a hope to learn whether oral sirolimus reduces ISS development.

The occurrence of in-stent restenosis for patients with metabolic syndrome who receive a DES in a non-target lesion will be assessed angiographically at 9 months.

WITHDRAWN
ATHERO: Advanced Technology Halting Early Re-Stenosis and Occlusion
Description

The rise of minimal access surgery has heralded the approval of a number of endovascular devices with similar indications. This is particularly true for the treatment of lower extremity ischemia. Comparable devices are selected for patient use somewhat arbitrarily, often dependent on industry influence. An unmet need is NON-industry sponsored prospective trials COMPARING devices head-to-head so that endovascular surgeons can even contemplate evidence-based device selection. At present, we seek to compare two new high-technology devices that are indicated to treat lower extremity arterial stenoses associated with claudication.

COMPLETED
Genomics of In-Stent Restenosis
Description

This study, conducted in Argentina at the Hospital Espa ol de la Plata and the Hospital Franc s de Buenos Aires, in collaboration with the NHLBI, will investigate possible genetic factors that lead to in-stent restenosis. A stent is a wire mesh tube that is surgically placed to open a blocked artery. The stent stays in the artery permanently, holding it open to improve blood flow. In the case of blocked coronary arteries, the stent improves blood flow to the heart muscle, relieving symptoms such as chest pain and shortness of breath. Sometimes re-growth of tissue within a stent, called in-stent restenosis, leads to narrowing of the artery, decreased blood flow, and a recurrence of symptoms. Genetic analysis may allow the identification of patient that may be at increased risk for in-stent restenosis and lead to methods of prevention and treatment. Patients 18 years of age and older who are undergoing coronary endarterectomy (surgery to remove plaque from an artery) to treat in-stent restenosis at the Hospital Espa ol de la Plata and the Hospital Franc s de Buenos Aires may be eligible for this study. Participants will have a blood sample drawn and undergo coronary endarterectomy. Tissue removed from the patient's artery or the stent during surgery will be analyzed for gene expression profiling and genotyping. The results will be studied along with information about the patients' medical history.
