Filter by:Non-randomized studies have shown that de-airing of the delivery system with an increased volume of saline may be associated to a decrease in periprocedural stroke during thoracic endovascular aortic repair. This study is designed to provide evidence that 4xIFU-dose volume of saline flush vs. standard IFU-dose saline flush is associated to a decrease in the amount of intra-sac air detected on the first follow-up imaging after EVAR.
Check whether patients with higher comorbidity and risk of complication, estimated using the V (p) -POSSUM score, ACS NSQIP and the ASA classification, present higher baseline activated clotting time values.
The ACURATE Neo2 PMCF is aimed at collecting clinical and device performance outcomes data with the ACURATE neo2™ Transfemoral Aortic Valve System as used in routine clinical practice for the treatment of severe calcific aortic stenosis.
The purpose of this registry is to collect safety and performance data on all commercially available Terumo Aortic knitted and woven grafts, and cardiovascular patches in standard clinical practice. Data will be collected both retrospectively and prospectively.
This study will aim to determine whether routine Point of Care Ultrasound (POCUS) assessment of volume status, cardiac function, and pulmonary function after major abdominal aortic surgery is an accurate and feasible form of monitoring for individualized, goal-directed resuscitation. Half of the patients will receive POCUS-guided fluid resuscitation, and the other half will be resuscitated using usual post-operative care.
This study aims to identify the molecular genetic causes of the variability in development of calcific aortic valve disease in bicuspid and tricuspid aortic valves and their associated aortic dilation.
The Montalcino Aortic Consortium (MAC) will provide the infrastructure to assemble large cohorts of patients with mutations in known heritable thoracic aortic disease (H-TAD) genes, define the phenotype associated with these genes, and determine genetic and environmental modifiers of H-TAD.
The study is a single-centre, prospective, observational cross-sectional imaging study aimed to determine if macrophage-mediated inflammation can be visualised in the aorta of patients with aortic dissection (AD) using ultrasmall super paramagnetic iron oxides (USPIO)-enhanced magnetic resonance imaging (MRI).
The primary hypothesis is that a tailored programme of genetic and imaging screening of first- and second-degree relatives of patients affected by non-syndromic forms of thoracic aortic diseases will identify individuals at risk of death from these conditions. These individuals would constitute specific population of patients, requiring dedicated imaging surveillance and/or earlier prophylactic aortic surgery.
Thoracic endovascular aortic repair (TEVAR) for disease involving the aortic arch remains complex and challenging due the angulation and tortuosity of the arch and its peculiar biomechanical environment. Currently, TEVAR planning is based on the analysis of anatomical features by means of static imaging protocols. Such an approach, however, disregards the impact of pulsatile forces that are transmitted as migration forces on the terminal fixation sites of the endograft, and may jeopardize the long-term clinical success of the procedure. Hence,the investigators aim to assess the migration forces acting on different proximal landing zones of the aortic arch by computational modeling, and develop in silico patient-specific simulations that can provide a quantitative evaluation of the stent-graft performance. Study's results are expected to provide valuable insights for proper proximal landing zone and stent-graft selection during TEVAR planning, and ultimately improve postoperative outcome.
