Experimental and numerical investigation of wire waveguides for therapeutic ultrasound angioplasty
Therapeutic ultrasound angioplasty is an emerging minimally invasive cardiovascular procedure for disrupting atherosclerotic lesions using small diameter wire waveguides. The lesions are damaged through a combination of direct ablation, pressure waves, cavitation and acoustic streaming caused by …

Promoting endothelialisation to reduce vascular injury following coronary angioplasty and stent implantation
… the clinical outcomes in patients undergoing angioplasty and stenting for coronary artery disease. I sought to establish a new cellular model to study the coronary endothelium in patients with acute myocardial infarction, and to utilise this model to identify novel polymer substrates that …

The Safety and Cost-Effectiveness of Carotid Angioplasty and Stenting in Calgary
Objectives To evaluate the safety and cost of carotid stenting in Calgary. Methods A cost-utility analysis from the perspective of the Canadian health care system was performed comparing stenting to endarterectomy using a decision analytic model. A prospective cohort study was done for trans …

Health-related Quality of Life One Year After Coronary Angioplasty and/or Coronary Stenting
… 1997). Percutaneous transluminal coronary angioplasty (angioplasty) and coronary stenting (stenting) are common revascularization treatments for coronary artery disease. Advances in cardiovascular technology have resulted in noninvasive treatment strategies in order to decrease symptoms, …

Transformer-Based Prediction of Coronary Artery Lumen Expansion Post Angioplasty Using Optical Coherence Tomography
… morphology and the processes of intervention. Angioplasty is an intervention which causes a previously constricted vessel to expand via placement of a stent, and is affected by numerous characteristics of the vessel such as calcium eccentricity and size, wall thickness, and prior lumen size. …

Plasma tissue factor, tissue factor pathway inhibitor and restenosis following femoropopliteal percutaneous transluminal angioplasty in claudicants
… therapy. However percutaneous transluminal angioplasty (PTA) is often performed to improve limb related symptoms. Claudicants may have variation in symptomatology and disease progression while awaiting PTA Moreover restenosis following PTA is a major therapeutic problem despite high initial …

A study on the short-term cognitive outcome of percutaneous transluminal coronary angioplasty with intra-coronary stenting
… outcome of percutaneous transluminalcoronary angioplasty with intra-coronary stenting. Participants were assessed cognitively using specific neuropsychological tests used to measure performance in the seven cognitive domains. Forty people took part in the study, with twenty of them making up …

Polo-Like Kinase 1 and Smooth Muscle Cells in Coronary Artery Bypass Conduits and Coronary Arteries Following Angioplasty
… following percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting that may contribute to greater SMC proliferation in the injured versus uninjured blood vessels in swine.|Approach and Results — At the basal level, higher expression of PLK1 and pPLK1 were noted …

Invasive Physiologic Assessment of Myocardial Viability After Primary Angioplasty in Acute Myocardial Infarction: Comparison With FDG-PET Imaging
BACKGROUND & PURPOSE: The state of coronary microcirculaton is an important determinant of myocardial viability and clinical outcomes in acute myocardial infarction(AMI). However, to date, there has been lacking in comparative studies on the most reliable invasive, on-site measurement for assessing …

Multi-modality Imaging to Determine the Role of Calcification and Inflammation on Restenosis Rates Following Lower Limb Angioplasty
… lower extremity percutaneous transluminal angioplasty (PTA). No such method exists to identify patients who are at risk from restenosis before intervention. Tracers of inflammation (18F-FDG; fluorodeoxyglucose) and calcification (18F-NaF; sodium fluoride) are higher in restenosis following …

Effect of an Outpatient Education Program on Knowledge and Healthy Behavior Change of Patients Who Have Undergone Percutaneous Transluminal Coronary Angioplasty
… undergone percutaneous transluminal coronary angioplasty was evaluated to determine if there was an increase in knowledge of a change in healthy behaviors as a result of the program. The sample consisted of 48 patients; 24 who experienced an outpatient education program and 24 who did not. …

An investigation of the fluorescence emitted by arterial intimas during irradiation by a XeCl excimer laser
Laser angioplasty of occluded arteries has been limited by the unacceptably high rate of vessel wall perforation. To overcome this limitation, fluorescence spectroscopy of arterial wall tissue has been proposed as a technique to discriminate between normal and atherosclerotic arteries and thereby …

Regulatory Mechanisms Underlying the Differentiation of Mesenchymal Stem Cells to Endothelial Cells
… occlusion of coronary arteries. Coronary angioplasty is performed to restore cardiac blood flow and function. Angioplasty is the most widely used interventional technique for coronary occlusion events. However, long term benefits are curtailed by vascular endothelium injury. Endothelial …

Inhibition of Vascular Smooth Muscle Cell Migration and Intimal Thickening with Chimeric N-Cadherin Mimetic Peptides: Development of a Novel Therapeutic Strategy for Restenosis
… arteries. The most common treatment for this is angioplasty and stenting, which has side effects of restenosis (re-narrowing) from smooth muscle cell (SMC) migration and proliferation, and late thrombosis due to endothelial cell (EC) death from indiscriminately cytotoxic chemotherapeutic agents. …
