Filter by:Patients with bicuspid aortic valve-related aortopathy are at increased risk of aortic dilatation, dissection and rupture. Currently, risk stratification is largely based on aortic diameter measurements, with those deemed high risk referred for aortic replacement surgery. This approach is imperfect, and potentially exposes many patients to unnecessary high-risk aortic surgery, or fails to identify those at risk of dissection or rupture with smaller diameters. In patients with abdominal aortic aneurysms, the investigators recently demonstrated that uptake of 18F-sodium fluoride predicts disease progression and clinical events independent of aneurysm diameter and standard clinical risk factors. Based on the investigators preliminary data, a study was proposed to look at 18F-sodium fluoride uptake in patients with bicuspid aortic valve-related aortopathy. The proposed study will shed light on the underlying pathological processes involved in aortic complications of this disease as well as potentially providing an important risk marker to predict disease progression and guide the need for major aortic surgery.
The study was created to evaluate the theoretical anatomical feasibility of the new E-nside Multibranch Stent Graft System (JOTEC GmbH, Hechingen) in patients with thoracoabdominal and para-renal aortic aneurysms based on retrospective review of pre-operative imaging studies of the patients treated with other techniques for this pathology in the vascular Unit of San Raffaele Hospital, in the past ten years. With this study, investigators want to analyze in how many cases the new prosthesis would be usable. E-nside Multibranch Stent Graft System (JOTEC GmbH, Hechingen) is in the pre-CE marking stage. At present, the certifying organism is evaluating the documentation for the release the CE mark certification and Declaration of Conformity.
Purpose of the study is the evaluation of the applicability of the percutaneous technique through double Proglide and Pre-Close Technique to the treatment of complex aortic aneurysms with thoracic endoprosthesis (TEVAR), fenestrated or branched (F / B-EVAR) in which patient-related factors, the devices used or the procedure, could affect the performance.
The primary objective of this research project is development and validation of a new, non-contrast gated aortic (NCGA) computer tomography scan algorithm for screening of aortic aneurysm in the chest and abdomen in at risk patients. This study would initially be performed in patients with a known aneurysm and done in addition to their indicated surveillance CT scan.
The objective of this prospective cohort study is to determine the prevalence of obstructive sleep apnoea (OSA) in patients with and without thoracic aortic aneurysm.
The purpose of this study is to evaluate the use of an investigational device called the ValiantTM Visceral Manifold Thoracoabdominal Stent Graft System for the repair of thoracoabdominal aortic aneurysms (TAAA), which is a balloon-like bulge in the aorta (major artery leading away from your heart) that originates in your chest and extends to your abdomen and also includes the branch arteries that supply blood to the liver, spleen, intestine, kidneys and other organs in your abdomen. The word "investigational" means the device is still being tested and is not approved by the Food and Drug Administration (FDA) for sale in the United States.
Since the development of custom-made fenestrated and branched endografts a novel therapeutic option for the management of thoracoabdominal and para-renal aortic aneurysms was made accessible. Because of the design of these branched endografts, an arterial vascular access from the upper limb is required to allow selective catheterization of the branch component and the respective target vessel (celiac trunk, superior mesenteric artery, renal artery).2
The objective of the study is to evaluate the safety and performance of Relay Pro and Relay NBS Pro devices in humans having thoracic aortic pathologies. Clinical results will be used to apply for the CE certification.
The aim of this prospective, explorative study of noninvasive neuromonitoring was to search potential and practical methods associated with neurological outcome in the perioperative and immediate postoperative setting of surgery of the thoracic aorta. These methods include abbreviated EEG monitoring, near-infrared spectroscopy, transcranial Doppler ultrasound and biochemical markers associated with neuronal damage.
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.
