Active clinical trials for "Coronary Stenosis"

Myocardial damage occurs in up to 40% of cases when sensitive biomarkers are measured after coronary artery stenting. Such events have been associated with poor outcomes both at 30 days and long term. The cause of such damage is multi-factorial and includes distal propagation of atheromatous and thrombotic debris and the subsequent infiltration of the microcirculation with inflammatory cells. Individually or together these events can occlude the micro-circulation and lead impaired blood flow to heart muscle. The vasodilator adenosine is commonly used in cases of impaired flow in an endeavor to improve flow rate and limit myocardial damage. Unfortunately the efficacy of this therapy is limited. More recently, there have been clinical studies looking at the administration of adenosine before any potential damage by ballooning or stenting, in an effort to avoid poor distal flow post procedure and thus limit any myocardial damage. Although small numbers of subjects have been included in these trials, there have been encouraging preliminary data. The aim of this study is to assess whether the use of intra-coronary adenosine given directly into the target coronary artery prior to stenting can reduce the incidence of myonecrosis (heart muscle damage)over placebo. We also aim to assess whether this translates to better outcomes at 30 day follow up.

The purpose of this study is to compare the BioMatrix Flex (Biolimus A9-Eluting) stent system with the Cypher SELECT (Sirolimus-Eluting) stent system in a non-inferiority trial.

This is a multi-center, prospective, non-randomized study. Approximately 90 patients from up to 16 centers will be entered in the study. Patients will be followed clinically for up to 5 years post-procedure. All patients will have a repeat angiography at 6 months follow-up. The primary objective of this study is to evaluate the safety and effectiveness of the Genous Bio-engineered R stentTM in conjunction with optimal statin therapy (80mg of atorvastatin), in the treatment of elective patients with up to two de novo native coronary artery lesions. The Genous stent received CE mark for the intended indication in August 2005

This study is divided into 5 arms: Randomized Clinical Trial (RCT): Prospective, randomized, active-controlled, single blind, parallel two-arm multi-center clinical trial in the United States (US) comparing XIENCE V® Everolimus Eluting Coronary Stent System (CSS) (2.5, 3.0, 3.5 mm diameter stents) to the Food and Drug Administration (FDA) approved commercially available active control TAXUS® EXPRESS2™ Paclitaxel Eluting Coronary Stent (TAXUS® EXPRESS2™ PECS) System US 2.25 mm non-randomized arm using 2.25 mm diameter XIENCE V® Everolimus Eluting CSS US 4.0 mm non-randomized arm using 4.0 mm diameter XIENCE V® Everolimus Eluting CSS US 38 mm non-randomized arm using 38 mm in length XIENCE V® Everolimus Eluting CSS Japanese non-randomized arm using XIENCE V® Everolimus Eluting CSS (2.5, 3.0, 3.5, 4.0 mm diameter stents) in Japan The TAXUS® EXPRESS2™ Paclitaxel Eluting Coronary Stent System is Manufactured by Boston Scientific.

The primary objective of this study is to further evaluate the safety and effectiveness of the TAXUS Express2 Paclitaxel-Eluting Coronary Stent System in long lesion lengths, small and large vessel diameters and with multiple overlapping stents in the treatment of de novo coronary artery lesions

The objective of this study is to demonstrate safe and effective use of the Ringer perfusion balloon catheter for dilatation/pre-dilatation of coronary stenoses during percutaneous coronary intervention (PCI).

This single-centre cross-sectional study aims to ascertain the impact of dyslipidemia on long-term graft patency after coronary artery bypass grafting (CABG).

The RESTORE II clinical trial is intended to assess safety and performance of the ReZolve2 Bioresorbable Coronary Scaffold in native coronary arteries.

The purpose of this study is to evaluate the safety and effectiveness of the AVJ-09-385 Small Vessel Everolimus Eluting Coronary Stent System (EECSS) (2.25 mm diameter stent) in treatment of subjects with ischemic heart disease caused by de novo lesions.

The study will enroll patients with angiographically significant coronary de novo lesions. Subjects will be randomized 1:1 and treated with a Lutonix catheter either before or after bare-metal stenting (BMS). The purpose is to assess the feasibility, safety and efficacy of the Lutonix Catheter for treatment of de novo coronary artery stenosis using two distinct treatment strategies.
