Active clinical trials for "Aortic Aneurysm"

The goal of this mechanistic clinical trial is to assess whether lowering the low-density lipoprotein cholesterol (LDL-C) levels in the blood with the injections of the medication evolocumab will have any effect on the tissue or cells of patients with abdominal aortic aneurysm (AAA). Researchers will compare participants receiving evolocumab injections to participants receiving placebo injections to see how the tissue and cells of the aorta are affected by changes in LDL-C levels.

This is a 2-group study comparing the effect of a "prehabilitation" program to usual care on quality of life and clinical outcomes in patients undergoing elective repair of their thoracic aorta.

The primary objective of the clinical investigation is to assess the use of the the Visceral Manifold Thoracoabdominal Aortic Aneurysms (VTAAA) stent graft system to repair thoracoabdominal aortic aneurysms in patients having appropriate anatomy. The primary intent of the study is to assess safety (i.e. freedom from major adverse events (MAE) at 30 days) and preliminary effectiveness (i.e., treatment success and technical success) of the device (i.e., the proportion of treatment group subjects that achieve and maintain treatment success at one year).

Multicenter, single arm, open label, registry study with consecutive, eligible patient enrollment at each site. All subjects undergoing the Endovascular Aneurysm Sealing System (EVAS) with the Nellix®-System. Subjects will be followed procedurally to discharge, and as per institutional standard of care thereafter through to 5 years (total follow-up commitment)

This is a global, prospective non-interventional, multi-centre, post-market study of the Vascutek Thoraflex™ Hybrid system in patients with acute thoracic aortic syndrome, subacute/chronic dissection of the aorta and aortic aneurysm.

Patients with bicuspid aortic valve-related aortopathy are at increased risk of aortic dilatation, dissection and rupture. Currently, risk stratification is largely based on aortic diameter measurements, with those deemed high risk referred for aortic replacement surgery. This approach is imperfect, and potentially exposes many patients to unnecessary high-risk aortic surgery, or fails to identify those at risk of dissection or rupture with smaller diameters. In patients with abdominal aortic aneurysms, the investigators recently demonstrated that uptake of 18F-sodium fluoride predicts disease progression and clinical events independent of aneurysm diameter and standard clinical risk factors. Based on the investigators preliminary data, a study was proposed to look at 18F-sodium fluoride uptake in patients with bicuspid aortic valve-related aortopathy. The proposed study will shed light on the underlying pathological processes involved in aortic complications of this disease as well as potentially providing an important risk marker to predict disease progression and guide the need for major aortic surgery.

Aggressive intraoperative and postoperative management of blood glucose may substantially decrease perioperative cardiovascular and infectious complications in diabetic and non-diabetic patients undergoing vascular surgery. The purpose of this study is to compare the tight versus traditional blood glucose control in diabetics and non-diabetics undergoing vascular surgery in regard to their postoperative fatal and nonfatal cardiac outcomes, and the secondary effects such as rate of infections, overall morbidity and 30-day mortality.

The primary purpose of this study is to assess the use of the TAAA Debranching Stent Graft System to repair thoracoabdominal aortic aneurysms in patients having appropriate anatomy, as measured by device safety, effectiveness, costs of delivery of aortic surgery care, and patient quality of life domains. Additionally, the study will assess technical success and treatment success at each follow-up interval.

This study is a prospective non-interventional, multi-centre study of the Vascutek Fenestrated Anaconda™ system, and is essentially a post-market study. The Vascutek Fenestrated Anaconda™ system is a custom made device used for the treatment of Abdominal Aortic Aneurysm.

An abdominal aortic aneurysm (AAA) is an enlargement or ballooning of the main artery supplying high pressure blood from the heart to the body. AAAs may continue to stretch until they burst (rupture) causing 7000 deaths per year in the United Kingdom (UK); 2.1% of all deaths in men over 65. Planned repair before rupture is critical and the National AAA Screening Programme (NAAASP) is being introduced to identify AAAs in men before rupture. Screening will identify over 9000 men per year with a previously undiagnosed AAA. More than 90% of screen detected AAAs are small, do no require repair, enter ultrasound follow-up (surveillance) and may benefit from exercise to improve fitness before repair. Over 4000 elective AAA repairs per year are performed in the UK and it has been suggested that exercise training and weight loss may reduce mortality and complications of AAA repair. This pilot study will examine the feasibility of supervised exercise training for patients with AAAs and determine the optimal duration of training to achieve worthwhile improvements in fitness.
