NCT ID: NCT03763812 Not yet recruiting - Clinical trials for Abdominal Aortic Aneurysm

Post Implant Syndrome After EVAR and EVAS (INSPIRE Study)

Start date: December 2018
Phase: N/A
Study type: Interventional

Retrospective data have shown that active sac management, as applied in EVAS, reduces the incidence of the post-implant syndrome. All-cause and cardiac mortality at one-year seems to be lower after EVAS when compared to EVAR. Ongoing, low grade, inflammation could differ between techniques and induce cardiac damage. This study is designed to establish whether EVAS results in a reduced post-operative inflammatory response during the first year after surgery, compared to EVAR as assessed by trends in circulating inflammatory cytokine concentration. Study design: International prospective, comparative, explorative study. Study population: Patients scheduled to undergo infra-renal EVAR with a polyester endograft or EVAS for an infrarenal aortic aneurysm. This is an explorative study and therefore only patients who would normally receive a suitable device as part of standard treatment at the participating institutes will be recruited. Blood samples will be taken at specified time points before and after surgery. Main study parameters/endpoints: The difference in early post-operative and long term inflammatory response between EVAS and EVAR, measured by the incidence of the post-implant syndrome. To investigate the incidence of the post-implant syndrome, the rise in CRP, WBC and circulating cytokines, at specified time points up to 12 months after surgery and the change in aortic thrombus volume and its relationship with the inflammatory response, measured by cytokines' concentrations.

Biomarker Profiling in Abdominal Aortic Aneurysm Patients

BIOMArCS-AAA
Start date: March 23, 2017
Phase:
Study type: Observational

The BIOMArCS-AAA study aims to investigate the associations of (temporal patterns of) blood biomarkers with aneurysm growth in patients with abdominal aortic aneurysm (AAA), with particular attention to biomarkers that have demonstrated prognostic value for adverse disease outcomes in coronary artery disease and biomarkers for the main genetic pathways associated with AAA.

NCT ID: NCT03687489 Not yet recruiting - Clinical trials for Abdominal Aortic Aneurysm

Safety and Efficacy Study of Abdominal Aortic Aneurysm Stent Graft System

Start date: October 31, 2018
Phase: N/A
Study type: Interventional

A prospective, multi-centre, objective performance criteria clinical trial to evaluate the safety and efficacy of Abdominal Aortic Aneurysm Stent Graft System manufactured by Lifetech Scientific (Shenzhen) Co., LTD. for the infrarenal abdominal aortic aneurysm.

NCT ID: NCT03507413 Not yet recruiting - Clinical trials for Abdominal Aortic Aneurysm

Metformin Therapy in Non-diabetic AAA Patients

MetAAA
Start date: September 17, 2018
Phase: Phase 2/Phase 3
Study type: Interventional

A prospective randomized, double blind, placebo-controlled, safety and efficacy study of metformin as add-on therapy in abdominal aortic aneurysm (AAA) OBJECTIVES Primary Objective - To demonstrate treatment efficacy of metformin in AAA in comparison to placebo or active comparator, as measured by growth of the AAA maximum diameter at 12 months Secondary Objectives - To asses inflammatory cytokines and parameters of neutrophil activation in AAA in response to metformin treatment by glucose - insulin - IL-6 - markers of neutrophil activation (MPO, elastase, NGAL)

NCT ID: NCT03493074 Recruiting - Clinical trials for Cardiovascular Diseases

Non-invasive Monitoring of Endovascular Repair of Abdominal Aortic Aneurysm (VBA)

VBA
Start date: April 8, 2018
Phase:
Study type: Observational

This study evaluates a novel noninvasive method to dynamically monitor the effect of abdominal aortic aneurysm (AAA) and endovascular treatment of AAA (EVAR) on arterial pulse wave

NCT ID: NCT03449875 Completed - Clinical trials for Abdominal Aortic Aneurysm

Global Post-market Registry for the Treovance Stent-graft.

RATIONALE
Start date: February 5, 2014
Phase: N/A
Study type: Observational [Patient Registry]

Patients with abdominal aortic aneurysms (AAA) suitable for endovascular aortic repair (EVAR) with Treovance were eligible to participate. Main inclusion criteria were: age 18-85 years; infrarenal AAA without significant infrarenal or distal iliac landing neck calcification or thrombus formation; infrarenal or distal iliac landing neck size requirements specified in the instructions for use. Main exclusion criteria: dissection/ruptured aneurysm or prior AAA endovascular or surgical repair. The primary endpoints were standard EVAR criteria.

NCT ID: NCT03429647 Completed - Clinical trials for Abdominal Aortic Aneurysm

Intraoperative Perfusion Patterns of the Sigmoid Colon During Elective Open Abdominal Aortic Aneurysm Repair

Start date: January 1, 2013
Phase: N/A
Study type: Interventional

Blood supply to the sigmoid colon during open abdominal aortic aneurysm (AAA) repair is at risk. Ischemia of the sigmoid colon after AAA repair is potentially devastative. No reliable measures to prevent it are available and the underlying mechanisms are poorly understood. The aim of this study is to describe intraoperative perfusion patterns of the sigmoid colon during open AAA repair and their potential impact on postoperative outcome.

NCT ID: NCT03425305 Active, not recruiting - Heart Failure Clinical Trials

Serum Uric Acid Levels and Onset of Cardiovascular Diseases: a CALIBER Study

Start date: January 1998
Phase: N/A
Study type: Observational

Serum uric acid level is a commonly measured biomarker. The association between serum uric acid level and the risk of developing cardiovascular diseases has been observed in some studies, while others showed controversial results. Estimation of this association may help to predict cardiovascular outcomes and may guide new treatment strategies. The hypothesis is that increased serum uric acid level is associated with a range of cardiovascular diseases.

NCT ID: NCT03320408 Recruiting - Clinical trials for Abdominal Aortic Aneurysm

Predicting Aneurysm Growth and Rupture With Longitudinal Biomarkers

PARIS
Start date: October 4, 2017
Phase:
Study type: Observational [Patient Registry]

First aim: PARIS study The main aim of the current study is to determine the association between abdominal aortic aneurysm (AAA) progression and the evolution of proteases and cytokines levels.To achieve this aim, we will prospectively collect blood, aortic tissue, patient data, and imaging data. Aortic tissue will only be obtained when patients undergo conventional open repair. The other biomaterials will be collected during regular patient follow-up visits, with a maximum frequency of once per year. Second aim: Pearl AAA biobank For future research purposes, a new biobanking infrastructure will be created to collect and store additional blood and urine samples in a biobank. This biobank will be embedded within the infrastructure of the 'Parelsnoer Institute' (PSI) and will be called Pearl AAA. The Pearl AAA will be established in the extension of the PARIS study

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:
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.
