NCT ID: NCT03296280 Enrolling by invitation - Heart Failure Clinical Trials

Evaluation of Implementation of a National Point-of-Care Ultrasound Training Program

Start date: October 3, 2016
Phase: N/A
Study type: Observational

This VA QUERI Partnered Evaluation Initiative will evaluate the impact of an immersive Point-of-care Ultrasound (POCUS) Training Course on provider skill acquisition and retention; the frequency of POCUS use by trained providers; and the barriers/facilitators to POCUS in the VHA. Data sources include pre- and post-course assessment tools, medical coding data, and course evaluations. Providers that participate in the POCUS Training Course will be compared to control providers from wait-listed facilities. Additionally, participating facilities vs. wait-listed facilities for the POCUS Training Course will be compared. Findings from this project will guide ongoing efforts of the investigators' operating partners, VA Specialty Care Centers of Innovation (SCCI) and the VA Simulation Learning and Research Network (SimLEARN), to develop a national POCUS training program and facilitate implementation of POCUS use system-wide in the VA healthcare system.

NCT ID: NCT03277781 Recruiting - Clinical trials for Abdominal Aortic Aneurysm

Female Aneurysm Screening STudy

Start date: November 1, 2016
Phase: N/A
Study type: Observational

An abdominal aortic aneurysm (AAA) is a swelling of the main blood vessel (aorta) in the abdomen. If the swelling gets too large the aorta can burst and this is usually fatal. In order to prevent rupture, AAA can be surgically repaired. This is usually carried out when the size of the AAA is more than 5.5cm in diameter as below this size, the risk of rupture is lower than the risk of surgery. AAA are usually asymptomatic before rupture but can easily and safely be diagnosed by ultrasound scanning. There is currently a national screening programme for men, but not women. Women are not screened for AAA on the basis that the disease is less common in females. However, 33.6% of all deaths caused by ruptured AAA in England and Wales are in females (1109 female deaths)1. Death rates due to ruptured AAA in men have nearly halved over the last decade but the reduction in female deaths over the same time period is less than one third. Females with AAA are also 4-times more likely to rupture their aneurysm and have higher rates of complications and death after emergency surgery than men. There are groups of females such as smokers, who are at high risk of AAA. The investigators have identified risk factors that are easily identifiable from general practice databases that may be able to identify women at high risk of AAA. In this research it will be determined whether it is feasible to select women for AAA screening using these risk factors, how many women in these high-risk groups attend if they are invited for AAA screening, and screen women to determine the numbers in the different risk groups who have AAA. This will allow the assessment of whether screening women for AAA could be clinically or cost effective and who would benefit the most. The investigators will also investigate if the siblings of patients with AAAs are at higher risk of disease by inviting them for screening too.

Use of Fish Oil to Reduce Inflammation During Endovascular Abdominal Aortic Repair

Start date: December 2016
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine if high-dose PUFA supplementation in patients undergoing EVAR for infra-renal AAA reduces the peri-operative inflammation.

NCT ID: NCT03180996 Recruiting - Clinical trials for Abdominal Aortic Aneurysm

Global Fenestrated Anaconda Clinical sTudy

Global FACT
Start date: September 11, 2017
Phase: N/A
Study type: Observational

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.

NCT ID: NCT03138434 Recruiting - Clinical trials for Abdominal Aortic Aneurysm

Advanced MRI in AAA

Start date: April 12, 2017
Phase: N/A
Study type: Observational

This study aims to determine whether advanced MRI sequences can provide robust and clinically relevant information about abdominal aortic aneurysms (AAAs). The MRI sequences will study outcomes related to blood flow inside AAA, microvasculature of the AAA vessel wall and intraluminal thrombus inside AAA. Robustness of these MRI sequences will be determined with testing of feasibility and reproducibility. Clinical relevance will be assessed by studying the association between the primary outcomes and disease severity. Disease severity will be expressed by AAA diameter. It is our hypothesis that these parameters are significantly related to disease severity and may therefore be future markers of disease progression.

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)

NCT ID: NCT02973308 Recruiting - Clinical trials for Abdominal Aortic Aneurysm

The Inter and Intra Reliability of Cardiopulmonary Exercise Testing in Abdominal Aortic Aneurysm Patients

Start date: September 2016
Phase: N/A
Study type: Interventional

Exercise testing is commonly being used in patients before surgery to test their overall fitness. One group it is being used in is patients who have an enlarged blood vessel in their stomach. This is known as an abdominal aortic aneurysm. The exercise test used is known as a cardiopulmonary exercise test as it looks at both heart and lung function at the same time. Whilst this test is commonly used there have been no studies (to date) which have looked at how reliable this test is; this means how well the investigators can obtain the same (or very similar) results after multiple tests. The investigators would like to test this reliability both between patients and the clinicians performing the testing.

NCT ID: NCT02875444 Completed - Clinical trials for Abdominal Aortic Aneurysm

Measurement of Maximum Diameter of Native Abdominal Aortic Aneurysm by Angio-CT

Start date: January 2013
Phase: N/A
Study type: Observational

Screening for an abdominal aortic aneurysm, monitoring its growth and evaluation of its risk of rupture are based on the measure of its maximum diameter. The abdominal aortic aneurysm's treatment to prevent its rupture is recommended from a threshold of 50-55 mm in men and of 45-50 mm in women. The importance of this measure for patient management justify a specific and homogeneous protocol of measure. However, the diversity of methods of measuring the maximum diameter with scanner and ultrasound was shown. The impact of various angio-CT based measures of maximum AAA diameter, and the impact of reproducibility limits on the decision to operate have never been investigated.

UVA Brain and Aortic Aneurysm Study

Start date: April 2014
Phase: N/A
Study type: Observational [Patient Registry]

The purpose of this study is to examine the percentage of patients who present with abdominal aortic aneurysms (AAA) will also have intracranial aneurysms (IA) and conversely; to examine the percentage of patients who present with intracranial aneurysms will also have abdominal aortic aneurysms.

NCT ID: NCT02846883 Recruiting - Clinical trials for Abdominal Aortic Aneurysm

Safety and Efficacy of Allogeneic MSCs in Promoting T-regulatory Cells in Patients With Small Abdominal Aortic Aneurysms

Start date: December 5, 2016
Phase: Phase 1
Study type: Interventional

This project is to determine the safety and explore the effectiveness of allogeneic (not cells of the participant but those of another human) mesenchymal stromal cells (MSCs) in decreasing inflammation and possible enlargement of the participants' abdominal aortic aneurysm. Participants will be selected as a possible subject because of an abdominal aortic aneurysm discovered on the ultrasound or computed tomographic ("CT") scan requested by the participants' doctor. The purpose of this study is to collect information that will be used to determine if MSCs can be used to decrease inflammation and possibly slow down enlargement of the participants' aneurysm. The investigators will also be collecting blood samples to study special inflammatory cells that cause aneurysms as well as asking participants to have a "PET" (positron emission tomography) scan that can measure inflammation directly in the participants' aneurysm.
