Filter by:The purpose of this study is to demonstrate improved vein graft patency rates at 12 months for endoscopically harvested saphenous vein grafts. The study will evaluate use modifications to existing techniques in vein graft handling during harvests. A secondary aim is to develop a standardized approach for harvesting, handling, and preparing vein grafts in the endoscopic approach.
The purpose of this study is to evaluate the safety and efficacy of Drug-Eluting Balloon first and then bare metal stent compared with drug-eluting stent for treatment of de novo lesions (DEB first).
The objective of this study is to identify proteomic inflammatory biomarkers to determine if there are differences in the biomarkers in patients who are treated using the CorMatrix ECM implant to close the pericardium and the patients whose pericardium is left open (the current standard of care).
This study evaluates the safety and effectiveness of the Momo Cobalt Chromium stent system for the treatment of single de novo lesions in a native coronary artery. The stent is coated with diamond-like carbon to decrease the risk of acute and late stent thrombosis, to increase the resistance towards corrosion and to significantly improve endothelialisation through the inhibition of elution of metallic ions.
The superiority of a percutaneous coronary intervention (PCI) by one stent over another in terms of clinical outcome is usually documented in large randomized controlled trials (RCT). Although generated from selected study populations these data form the basis for evidence based practice (EBP) in the entire population of patients considered for coronary intervention. An inherent limitation of this approach is that study populations differ significantly from all comers in terms of patient characteristics and prognosis undermining the foundation for extrapolation of trial results to all comers. Furthermore, other trials are based on a "one-fits-all" concept, while the benefits of an "individual-tailored" approach that might be superior, is not investigated. The Purpose of the current study is to - Compare clinical outcome between several CE marked drug eluting stents - Compare clinical outcome between several CE marked bare metal stents - Compare clinical outcome in all comers with that of the selected study population of RCT's - Evolve methods to compare clinical outcomes between the generalized "one-fits-all" versus the individualized or "individual-tailored" stent selection approaches The Method employed is - All comer PCI registry - single centre - Randomisation of all eligible patients within the registry to one of several study stent - Quality assurance in non-randomized population within the registry by periodical alternating the institutional standard stent - Continuous follow up of all patients included the registry by means of systematic event detection and classification by an independent safety and end point committee - Assessment of effects on quality of life by heart and health questionnaires Outcome Measures Primary endpoints: - Composite of cardiac death, acute myocardial infraction and target vessel revascularisation - Stent thrombosis - A specifically developed Treatment Failure Rate classification Secondary outcome measures include each of the above, target lesion revascularisation and total death analyzed in a hierarchical fashion at 2, 3, 4 and 5 years. Tertiary outcome measure is self reported quality of life based on health questionnaires on general health and cardiac symptoms. Power Calculations An event rate of 20% within 5 years, a relative difference of 25% (an absolute difference of 5%), P< 5%, Power > 80% => 900 patients in each of two treatment arms. Prespecified Analysis include 1. The MACE rates between stent types 2. The Stent thrombosis rates between stent types 3. The Treatment failure rates between stent types 4. The randomized population versus non-randomized population 5. The individualized versus the generalized Population 6. QOL between stent types
Objectives The CATCH trial (CArdiac cT in the treatment of acute CHest pain) is a prospective randomized controlled trial designed to evaluate the clinical value of cardiac multidetector computed tomography (MDCT) as a first-line diagnostic strategy in patients with acute chest pain, compared to a conventional functional-based testing strategy. Methods: Consecutive patients admitted with acute chest pain of suspected cardiac origin, but normal electrocardiogram and biomarkers were randomized to evaluation with 320-MDCT coronary angiography (CT-guided group) or with standard bicycle exercise test and/or myocardial perfusion imaging - MPI (Control group). After one year, patients will be followed-up, with registration of clinical endpoints such as Cardiac death, myocardial infarction, need for revascularisation, admittance for heart related problems, sustained chest pain, live quality score, use of medication.
The primary objective of this study is to evaluate safety and efficacy of the BIOTRONIK PRO-Kinetic coronary CoCr-stent in patients with single de novo lesions of native coronary arteries.
The purpose of this study is to examine the role of every day experiences as they relate to coronary artery disease (CAD).
The purpose of the Registry is to provide continuing evaluation and periodic reporting of safety and effectiveness of Medtronic market-released products. The Registry data is intended to benefit and support interests of patients, hospitals, clinicians, regulatory bodies, payers, and industry by streamlining the clinical surveillance process and facilitating leading edge performance assessment via the least burdensome approach.
The purpose of this study is to assess the pharmacodynamic effect of ticagrelor in African American patients with stable coronary artery disease.
