Filter by:The purpose of this study is to evaluate patency rates of the eSVS Mesh Saphenous Vein Graph (SVG) and control SVG at six and twenty-four months via coronary angiography and analyses of Duplex Sonography Results and coronary angiography and major cardiovascular or cerebrovascular event (MACCE)-Rate as well as analysis of preoperative great saphenous vein (GSV) duplex sonography and intra-operative GSV harvesting findings and procedure.
The purpose of the study is to see whether intensive smoking intervention on the day of operation can reduce per- and postoperative complications in patients operated for acute ischaemic disease compared to control group with no intervention.
The purpose of this study is to evaluate patency rates of the external Saphenous Vein Support (eSVS) Mesh Saphenous Vein Grafts (SVG) and Control SVG at 3-6 months and 24 months.
This study proposes to assess the effect of the standard of care, which is continuation of the pre op beta blocker dose into the post operative period compared to the administration of esmolol titrated to a pre determined target HR. The primary outcome will compare postoperative plasma levels of metoprolol in 2 cohorts in a group who has been continued on metoprolol (administrated via a nasogastric tube in NPO patients) to a group who has been withdrawn from metoprolol but given an esmolol infusion titrated to HR. Secondary outcomes will compare a) the hemodynamic responses, documenting the incidence of unplanned hypotension and bradycardia and b) to compare the effects of Heart rate to the incidence of myocardial ischemia, arrhythmias, delirium and infarction.
The purpose of the ABSORB BTK Clinical Investigation is to evaluate the safety and efficacy of the Everolimus Eluting Bioresorbable Vascular Scaffold System (BVS) in subjects with critical limb ischemia (CLI) following percutaneous transluminal angioplasty (PTA) of the tibial arteries.
LT1009-Oph-002 is a Phase 1b study designed to evaluate the safety and potential efficacy of iSONEP following one, two or three injections of iSONEP, as needed, for the treatment of Pigment Epithelial Detachment (PED) secondary to PED Secondary to Exudative Age-Related Macular Degeneration (AMD) or Polypoidal Choroidal Vasculopathy (PCV).
All people who have a heart transplant are at risk for developing cardiac allograft vasculopathy (CAV). CAV means narrowing of the heart transplant vessels, which is associated with poor heart transplant function. People who develop antibodies after transplant have a higher risk of developing CAV. Infections, high cholesterol, and rejection also increase the risk of developing CAV. People who develop CAV usually have to receive another transplant.
Long-term, observational, prospective, multicenter registry following patients who have been implanted with the SUPERA Interwoven Self-Expanding Nitinol Stent for treating stenosis in the superficial femoral and/or femoropopliteal arteries.
Primary objective of the study is to test whether an intensified insulin therapy incorporating the target of normal fasting glucose (<5.5 mmol/L) and glycated hemoglobin <6.5% is able to halve the incidence of angiographic restenosis at 6 months (expected rate 45%, to be reduced at 15%) after peripheral angioplasty compared with standard care to achieve a glycated hemoglobin <7.0% in patients with type 2 diabetes and limb ischemia. Secondary objectives include the identification of markers associated with, and predictive of, restenosis and the investigation of the underlying pathophysiological background, with specific focus on the role of nitric oxide (NO), mechanisms of endothelial activation/apoptosis, inflammation and matrix remodeling risk profiles, candidate gene polymorphisms and endothelial progenitor cells evaluation. Methodology: This is a randomized, open-label, clinical trial comparing two regimens of insulin therapy having as an outcome measure the incidence of angiographic restenosis at 6 months after peripheral angioplasty. Seventy consecutive patients with type 2 diabetes and peripheral arterial disease undergoing peripheral angiography and subsequent angioplastic procedure will be studied. Patients will be treated by intensive insulin therapy, based on three pre-prandial administrations of regular insulin or short acting insulin analogues combined with the long-acting insulin analogue glargine or standard care based on once-daily insulin and oral antidiabetics agents. Patients randomized to the intensive insulin therapy arm will be educated and followed up with daily measurements of fasting glucose and weekly phone contacts with the target of fasting glucose <5.5 mmol/L (99 mg/dl) to obtain glycated hemoglobin <6.5%. The control arm will be followed to achieve a target of glycated hemoglobin <7.0%. Life style recommendations, including diet and physical activity program, will be the same for the two arms. All patients will undergo three visits with physical examination and blood sampling, at baseline and at 2, 4 and 6 months after angioplasty. Moreover, patients on normal fasting glucose arm will be monitored by phone on weekly basis in order to test their adherence to therapeutic target.
This is a multi-center, clinical pilot-study of ProEndoTecc Vascular Grafts (6, 7 or 8 mm Diameter) as superficial femoral artery bypass/interponate. The aim of this study is to demonstrate safety of implantation, patency and durability of a new type of vascular graft.
