Filter by:Immersion sedation in virtual reality could be an alternative to conventional pharmacological sedation, during interventional cardiology acts on pain and anxiety control. The objective of this study is to determine whether virtual reality immersion is non-inferior to drug sedation on pain and anxiety, during coronary angiography or angioplasty.
According to the World Health Organization data, approximately 17.9 million people die every year due to heart disease. 85% of these deaths are due to heart attack and blocked blood vessels. The Turkish Statistical Institute reports that circulatory system diseases took the first place among the causes of death with 38.4%, while ischemic heart diseases constituted 39.7% of these deaths in 2018. Transradial angiography is used for the purpose of scanning and treatment of coronary arteries both in Turkey and in other countries of the world. Aim: After transradial angiography, Terumo (TR) band is used as a common device which is provides pneumatical hemostasis. This study aims to reduce usage time of the TR band, a decrease of hematoma formation and a reduction in the level of extremities pain experienced as a result of transradial angiography, thanks to using the TR band together with cold application.
This is a French, prospective, single-arm, multi-center registry to confirm the safety and efficacy of the Diamondback 360 TM Orbital Atherectomy System in the preparation of de novo calcified coronary lesions before implantation of a coronary endoprothesis in adult subjects. The primary safety endpoint is 30-day MACE and the efficacy endpoint is procedural success.
In patients with Out-of-Hospital Cardiac arrest who achieves Return Of Spontaneous Circulation (ROSC) The investigators want to evaluate whether there is a benefit from acute Angiography compared to subacute (12-24 hours) Angiography
The research was planned on a randomized controlled experimental basis. Simple stratified randomization will be performed according to gender and age. Consent will be obtained from children and parents who agree to participate in the research. Before angiography, "Child Fear Scale", "State-Trait Anxiety Scale (STAI-TX)", and "Vital Signs Follow-up Form" will be applied to all children taking part in the study and life signs will be recorded. During angiography, the first group will listen to the music that the child wants to listen to. The second group will listen to the music which determined by the researchers. No music will be played to the control group. During angiography (when the child is listening to the music) vital signs will be recorded in 0. min., 1st minute, 5th minute, 10th minute, 15th minute, 30th minute and 60th minute. "Numerical Pain Scale", "Child Fear Scale", "State Anxiety Scale", and "Vital Signs Follow-up Form" will be re-evaluated to all three groups after angiography.
Revadiab is case-control study aimed to demonstrate that retinal capillary density is altered in patients with type 1 diabetes with glycemic variability compared to those with comparable glycemic control without glycemic variability. An OCT angiography will be used to precisely evaluate retinal capillary density. A secondary objective will be to evaluate if glycemic variability is associated with cognitive dysfunction, using a neuro psychologic evaluation.
Currently, adrenal venous sampling (AVS) serves as the gold standard for subtyping of PA. Right adrenal vein catheterization is often difficult due to unfavorable anatomy of the vein including small vein size, short length, caudal direction for the transfemoral approach, and rare drainage to the accessory hepatic vein. All of these factors limit the widespread use of this approach. Given that the right adrenal vein is angled caudally in most patients, AVS via an antecubital approach was performed since January 2012. The purpose of this multicenter retrospective study was to evaluate the safety and feasibility of AVS via the antecubital approach.
The incidence of isolated common iliac artery (CIA) aneurysms is low, but in combination with an abdominal aortic aneurysm (AAA) they are found in approximately 20-40% of cases. Basically, two different endovascular strategies can be applied to treat a CIA aneurysm with, including 1. the coverage and 2. the preservation of blood flow to the internal iliac artery (IIA). Coil and coverage of the IIA is related to ischemic complications, including buttock claudication, erectile dysfunction and the more severe spinal and colonic ischemia. Iliac branched devices (IBD) have been developed to exclude CIA aneurysms preserving the IIA and currently three alternatives are on the market. Clinical results of these devices are promising but loss of patency is not uncommon. The major difference between the two devices is the IIA component. The Cook IBD uses a -non-dedicated IIA component, while in the GORE® EXCLUDER® Iliac Branch Endoprosthesis (Gore IBE device) a dedicated self expanding stent is used. Stresses and forces exerted onto the endograft by aortic pulsatility may have an effect on the durability and functioning of the endograft. Intermittent hinchpoints could also have an effect on stent integrity and stenosis. By evaluating endograft movement during the cardiac cycle (ECG-gated CTA) it is possible to assess the stress and force exerted onto the endograft. This might help gain insight into mechanisms underlying potential endograft failure, and aid procedural planning and the development of future devices with long-term durability. The choice for device is not part of this study.
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.
This study is a prospective, multi-center, randomized controlled clinical trial, aims to assess the safety and effectiveness of Optical Coherence Tomography or Intravascular Ultrasound or Quantitative Coronary Analysis to guide Firehawk stent implantation , and compared the treatment of moderate-to-severe calcified lesion in coronary artery.
