Filter by:This study aims to investigate Serum Tenascin C levels in patients with acute symptoms relating to a known or newly diagnosed aortic aneurysm in emergency department and reveals the possible role of Tenascin C in the development of the disease.
This is a Phase IV multicenter, open-label study and is being implemented in order to assess diagnostic image quality of MDCTA in subjects undergoing computed tomography angiography (CTA) of the thoraco-abdominal aorta, and the carotid, pulmonary and peripheral arteries with IOMERON.
This is an early feasibility study that investigates the outcome of selected patients with complex thoracoabdominal aortic lesions who are suitable for endovascular (within the vessel) repair with a physician-modified Medtronic Thoracic Valiant stent graft. The Medtronic Valiant System includes a Valiant Thoracic Stent Graft, a self-expanding, tubular end prosthesis which is modified/customized by the Investigators to fit the patient's anatomy. The device is constructed by making a taper in the larger proximal thoracic device and attaching it to a smaller distal thoracic device. The Viabahn branches for the visceral vessels are sutured to holes made in the tapered section. The modified Valiant stent graft is advanced to the lesion site endoluminally via the iliac/femoral artery. Access for delivery of extensions to the device will be delivered through the left subclavian artery. Upon deployment, the stent graft self-expands at the target location, where it is designed to exclude the lesion by restoring blood flow through the stent graft lumen.
The aim of the investigator is to implement 4D FLOW MRI technique into a clinical setting and evaluate the blood flow pattern and wall sheer stress in patients with aortic and/or aortic valve diseases.
This prospective study was designed to analyse the postoperative and long-term outcomes of total laparoscopic vs. open surgical repair of infra-renal abdominal aortic occlusive disease (AOD) and infra-renal aortic aneurysmal disease (AAA) in comparable groups of patients using a propensity analysis model.
The purpose of this study is to evaluate the clinical outcomes of transcatheter aortic valve replacement (TAVR) in the Asian Pacific population
This is a French Registry mandated by the French National Health Authority assessing long-term (5-years) safety of the GORE® TAG® Thoracic Endoprosthesis treating diseases of the thoracic aorta.
CD39 and CD73 was known protein expressed on surface of Th1 and Th17 cell and modulate immune related reaction. Cardiopulmonary bypass (CPB) can induce inflammatory reaction during cardiac surgery, and induce immunosuppression. Propofol and volatile anesthetics were related to immune reaction. However, the effect of propofol and sevoflurane on the change of CD39 and CD73 after CPB was not evaluated in previous studies. The authors hypothesized that the expression of CD39 and CD73 would differ between propofol- and volatile anaesthetic-based anaesthesia in patients undergoing CPB. Therefore, the present study determined the effect of propofol and sevoflurane on CD39 and CD73 during and after CPB.
Bicuspid aortic valve (BAV) disease is the most frequent congenital cardiac malformation, occurring in 0.5-1.2% of the US population. In young adults, it is generally a benign abnormality; but in older adults it is associated with thoracic aortic aneurysm or dissection in 20-30% of those with BAV. BAV is strongly associated with early development of aortic valve calcification or incompetence in >50% of BAV patients, and accounts for ~40% of the >30,000 aortic valve replacements (AVR) performed in the US each year. Yet, we know little of the etiology, cellular events and modifiers of progression of BAV to calcific aortic valve disease and we still do not understand the genetic cause(s) of BAV despite evidence for its high heritability. The Specific Aims of this study are: 1. To identify the genetic causes of bicuspid aortic valve disease and its associated thoracic aortic disease. 2. To identify potential pathways to predict the clinical course of BAV disease and for treating human BAV disease. To achieve these aims, we have created the International Bicuspid Aortic Valve Consortium (BAVCon), a consortium of institutions with cohorts of BAV patients and the expertise to fulfill the performance of these aims.
This study hopes to determine the optimal antifibrinolytic dosing to decrease bleeding and blood transfusion after cardiac surgery without increasing adverse events
