Filter by:Traditionally, coronary angiograms are performed through the radial artery which is accessed above the palm of the 'right' hand. In recent years, some cardiologists are performing this procedure from the back of the wrist in as the radial artery courses through the anatomical snuffbox (distal radial access). The aim of this study is to determine the prevalence of hand dysfunction following coronary angiography via the distal radial artery.
The aim of the study is to demonstrate safety and effectiveness of ByCross Rotational and Aspiration device used for revascularization of total or sub-total occluded peripheral arterial vessels equal to or larger than 3mm in diameter. The ByCross is a single use, disposable, minimal invasive aspiration rotational atherectomy device. The ByCross is aimed to enable effective revascularization and restore blood flow in peripheral occluded vessels. In cases that the artery is completely blocked such that opening is not possible with currently available solutions and the procedure cannot be completed, the device is capable of crossing the blocked lesion without guiding wire and enables the completion of the procedure in a safe and effective manner, thus potentially eliminating the need for open bypass surgery. The ByCross can be used in several pathologies: calcified atheroma, old and fresh thrombus. Eligible adult patients with symptoms due to chronic sub-total and total occlusion will be enrolled and undergo percutaneous procedure including use of ByCross which will normally be followed by balloon inflation (Percutaneous Transluminal Angioplasty) in the artery at location where blockage has been opened by ByCross to further open the artery and restore full opening, and in some case followed by placement of a stent for long term stabilization. For demonstrating safety and effectiveness up to 42 patients will be enrolled. the procedure will take up to 2 hours followed by up to 48 hour hospitalization. Patients will then come for follow-up monitoring and examination 30 days and 6 months after procedure. Although this is unlikely, in some cases the physician can decide during procedure that following ByCross opening of the artery, ballooning or stent is not required. In this case the patient will come for another follow-up visit after 12 month.
Optimizing the MRI protocol in acute ischemic stroke remains a challenging issue. In this field, susceptibility-weighted sequences have proved their superiority over T2. Besides the strengthened susceptibility effect, enhanced susceptibility-weighted angiography (eSWAN) sequence provides also a time-of-flight (TOF) effect, allowing the exploration of the intracranial arterial circulation. The objective of this study is to compare eSWAN and 3D TOF, considered as the reference, in the detection of arterial occlusion in acute stroke.
Although expert consensuses recommend the use of statins in the treatment of atherosclerotic renal artery stenosis, in patients with severe atherosclerotic renal artery stenosis undergoing stent placement, the related investigation focused on renal protection by intensive lipid-lowering therapy is scant , and the optimal target level for lipid reduction remain uncertain. Therefore, we hypothesized that intensive lipid lowering could offer more benefits with respect to renal function in the patients with percutaneous renal artery stenting. We conducted the prospective randomized unblinded trial to compare the renal-protective effect of intensive lipid lowering with that of conventional lipid lowering in patients underwent renal artery stenting (75 patients in each study group)
Peripheral artery disease (PAD) is the third most prevalent cardiovascular disease worldwide, with over 200 million people affected. Most prominent symptom is leg pain while walking known as intermittent claudication. Based on the currently existing gaps in the management of intermittent claudication, the objective of the this study is to explore the clinical effectiveness and cost advantage of TeGeCoach, a 12-month long home-based exercise program, compared to usual care. TeGeCoach consists of telephone health coaching, remote walking exercise monitoring based on wearable activity monitors and intensified primary care. It is hypothesized that TeGeCoach will improve functional outcomes and will reduce total health care costs.
The purpose of the study is to evaluate the efficacy and safety of actovegin in participants with peripheral arterial disease (PAD) Fontaine Stage IIB.
Purpose of the study is to examine the retinal blood flow in chronic cases of retinal artery occlusion with non-invasive, non-contact optical coherence tomography angiography.
Coronary artery disease (CAD) is one of the major health concerns among other non-communicable diseases globally. Cardiac catheterization is a diagnostic gold standard to determine the extent of disease in coronary arteries due to atherosclerosis. Among the two approaches for cardiac catheterization, trans-radial approach has gained more popularity than conventional trans-femoral approach over the past decade with availability of compression devices for radial artery that assures lesser risk of bleeding and hematoma and has translated into increased patient comfort and early mobility post procedure. Radial artery occlusion is a common complication of trans-radial procedures often ignored by the operator after procedure due to dual blood supply by ulnar artery. Although clinically silent usually, it necessitate the need of monitoring radial artery for patency because of risk of limited trans-radial access later.Reportedly, RAO occurs in about 10% of cardiac catheterizations. , compression devices applied after sheath removal may be a contributing factor to radial artery occlusion because of selective pressure for extended time duration (3-4 hours). Various protocols have been developed to remove TR band by different institutions across the globe and have been tested to assess post procedure complications. To the best of what we know, there exists no standard protocol to deflate TR band. Also, the current protocol in practice at our institution has not been evaluated against other protocols that are followed in other institution across the globe claiming lesser post procedure complications. Hence, our aim was to test through a randomized trial whether our hospital standard protocol is non-inferior to the existing international protocol of Cohen & Alfonso that promises lesser complication rate
Background: CCTA is a common way to evaluate coronary artery disease. It stands for coronary computed tomography angiography. It uses scanning to look at the arteries that supply blood to the heart. It is noninvasive, widely available, and generally accurate. But it does expose people to radiation. Exposure to high amounts of radiation can increase a person s risk of getting cancer. Researchers want to learn more about the relationship between CCTA and radiation exposure. Objective: To see how much radiation is used to take pictures of the heart and how measures to reduce radiation are used around the world. Eligibility: People ages 18 years and older who need a computed tomography (CT) scan of the heart Design: Participants will be screened with a review of their medical records. Participants may have a pregnancy test. Participants will have the scheduled scan. Small, sticky discs will be placed on the chest. A small tube will be placed into a vein in the arm. A contrast material (dye) will be given through it. Participants will lie on the CT scanning table. A CCTA scan usually takes about 15 minutes if the heart rate is slow and steady.
The aim of the THEIA study is to determine if Alteplase administrated within 4.5 hours improve visual deficit due to acute CRAO with a good safety profile.
