Filter by:Mortality of thoracic aortic aneurysm and dissection (TAAD) remains high because of the huge blood lost from the aorta. Questions about the potentially genetic effects on sporadic TAAD are raised by researchers to explore the possible mechanisms leading to sporadic TAAD and to establish new clinical approaches to prevent TAAD-caused adverse clinical outcomes. This study is intended to collect the gene information in sporadic TAAD patients and to explore the relationship between genetic variation and the incidence of sporadic TAAD for further study.
Spontaneous Coronary Artery Dissection (SCAD) is a rare and often misdiagnosed cause of Acute Coronary Syndrome (ACS) affecting predominantly young women without cardiovascular risk factors. The origin of SCAD remains uncertain but a strong and frequent association with Fibromuscular Dysplasia (FMD) has been recently reported based on imaging evidence only. The aim of our study is to assess the presence of FMD and its genetic determinants i in a sample for haematoma or spontaneous coronary artery dissection. From May 2016 to 2018 we plan to include prospectively and retrospectively 200 patients admitted for ACS with confirmed diagnosis of SCAD. This study will be conducted in more than 30 French interventional cardiology centers. Coronary angiograms or intracoronary imaging data will be reviewed by two experienced interventional cardiologist experts in SCAD diagnosis. For each patient a genetic analysis will be performed. A systematic screening for FMD will be realized by computed tomographic or MRI angiography of renal, cerebrovascular and iliac arteries and reviewed by two experienced radiologists. A one year follow-up is expected. This study aims to confirm the presumed association of FMD and SCAD through the exploration of several artery beds and the study of confirmed genetic determinants, which has never been described previously to our knowledge.
The study will assess the effectiveness, safety and clinical outcomes of the Thoraflex™ Hybrid Device in the treatment of aortic disease affecting the aortic arch and the descending thoracic aorta, with or without involvement of ascending aorta. The study will also assess safety and early clinical outcomes in patients who receive an extension procedure within 1 year of Thoraflex™ Hybrid Device implantation. Lastly the study will assess the safety and clinical outcomes of patients who receive a Thoraflex™ Hybrid Device for treatment of a ruptured aorta. Patients will be followed for 3 years. The Primary Endpoint will be freedom from defined Major Adverse Events (MAE) occurring ≤ 1 year post-procedure.
Dexmedetomidine has been known to protect the lung against inflammation and oxidative stress in diverse clinical settings. The investigators aimed to investigate the lung protective effect of dexmedetomidine in patients undergoing thoracic aortic surgery with hypothermic circulatory arrest, which is associated with systemic inflammatory response, and oxidative stress.
The Investigators are performing a study to determine, in patients with chronic/recurrent neck pain, the cerebrovascular hemodynamic consequences of cervical spine movements, including manipulation, in vivo using fMRI technology on vertebral and cranial blood flow dynamics affecting brain perfusion, and extend the current data set on these variables
Video-assisted thoracoscopic surgery (VATS) for thoracic surgery is practical, has been shown to reduce postoperative discomfort, and has improved cosmetic results when compare to open thoracotomy. The specific aims of this project are: to clarify the physiologic and immunologic effects of different approaches for minimally invasive thoracic surgery: (1) multiple-port VATS; (2) single-port VATS
The purpose of the study is to conduct a randomized controlled trial comparing best medical therapy (BMT) alone to BMT with thoracic endovascular aortic repair (BMT+TEVAR) for uncomplicated acute type B aortic dissection.
The Zenith® Dissection extended study is to collect confirmatory safety and effectiveness data on the Zenith® Dissection Endovascular System in the treatment of acute, complicate Type B aortic dissection.
The purpose of this study is to explore whether the addition of Hemopatch to standard care can reduce prolonged air leaks and shorten the use of air drainage tube after surgery in thoracic lung surgery patients at high risk for prolonged air leaks.
That the full-moon stage of the lunar cycle is associated with reduced mortality and shorter length of stay in patients undergoing repair of aortic dissection, after adjusting for seasonal effects, demographics and cardiovascular risk factors.
