Filter by:This trial aims to demonstrate the safety and validity of extracorporeal fenestration and in situ fenestration in patients with aortic disease involving the left subclavian artery.
This is a national, multicenter, open-label, randomized, controlled, endpoint-blinded clinical trial of patients diagnosed with ATAAD and undergoing "Sun's procedure" coordinated by the First Affiliated Hospital of Xi'an Jiaotong University, China. Per the protocol, "Sun's procedure" combined with "XJ-Procedure" in the anastomosis of the aortic root and Sun's procedure combined with regular suturing methods of the aortic root will be compared.
Rationale: Aortic diameter is currently used as a gold standard in international guidelines for prediction of aorta pathology (aortic aneurysm and aortic dissection). However, aortic diameter has proven to be insufficiently accurate for making decisions about well-timed preventive interventions. The LANDMARC study will take place in line with the FIBAA-bank ('Correlatie tussen cardiovasculaire FIBroseringsgraad en Aorta elongatie, dilatatie en Atria dilatatie (FIBAA-bank): een biobank & databank onderzoek met focus op aorta en atria' (METC-number 2022-3164)), and aims to reveal the undiscovered relationship between WSS (wall shear stress) values and aortic strain. In combination with data from the FIBAA-bank, the LANDMARC study will provide more accurate information for future risk stratification models for cardiovascular pathology (with focus on aortic disease). Objectives: Primary objective: indication of the association between WSS (peak WSS and WSS gradient) (through 4D-flow MR and CT) and aortic strain. Secondary objective: indication of the association between (hemo)dynamic processes within the body (aortic elongation/aortic strain) and (patho-)physiological changes (degree of cardiovascular tissue fibrosis).
Activated clotting time (ACT) is currently recommended to monitor high concentrations heparin anticoagulation. ACT-LR was specifically designed to measure the activity of low dose of heparin used during endovascular surgery. The correlation between ACT-LR and Anti Xa activity which is considered as the gold standard seems to be debated. Few studies in literature had shown controversial results. These studies were conducted in patients who underwent open as endovascular surgery. However, the ACT monitoring is not recommended in open surgery. In addition, heparin administration protocols are not described and specific to each centre. In this study investigators want to study the correlation between LR-ACT and anti Xa after introducing a heparin protocol during complex endovascular procedures.
The aorta is the principal arterial vessel arising from the left heart that transfers blood to the body. Certain genetic and familial disease processes are known to weaken the aortic wall resulting in dilation and potential rupture. These aortic complications carry high mortality (>25%) and current management is orientated towards early detection and preventive treatment. Aortic dilation can also result in aortic valve dysfunction leading to heart failure. The estimated UK incidence of aortic disease per year is around 10 per 100,000 individuals, with 2000 people per year dying from aortic complications. The 2017-2020 National Adult Cardiac Surgery Audit report identified the number of people receiving surgery for aortic dissection in Scotland is per population proportionately lower compared to England (4.6 per million per year in Scotland vs. 6.6 per million per year in England). The reasons for this are unclear but may relate to the prevalence of aortic disease or a large geographic distribution with compromised access to specialized centres. Currently surgery is recommended when the aortic diameter exceeds a certain threshold. There are several types of effective surgical procedures, but there is still limited information on their long-term outcomes and the advantage of one procedure over another. The aims of the project are firstly to determine the clinical outcomes of the surgical procedures that are currently employed in Scotland to treat proximal aortic disease and secondly to describe the prevalence and distribution of proximal aortic disease within the Scottish population. The project will be hosted by the Golden Jubilee Research Institute. Contemporary and retrospective data will be collected from all the Scottish Cardiothoracic Surgery units which are based in Glasgow, Edinburgh and Aberdeen. This will be the first study to analyse surgical outcomes for ascending aortic disease in Scotland, and the first to describe the epidemiology of aortic disease within the population. It is anticipated that the results will guide current surgical practise, and provide data to inform national service provision for the management of proximal aortic disease.
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.
