Active clinical trials for "Aortic Aneurysm, Thoracic"

Multicenter, single-arm retrospective and prospective registry is being conducted to confirm the clinical performance and safety of GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis when used as a Bridging Stent with Branched and Fenestrated Endografts in the Treatment of Aortic Aneurysms Involving the Renal-Mesenteric Arteries.

Multi-arm, multi-center, open label, prospective observational registry designed to obtain safety and performance data on the use of CE marked and custom Terumo Aortic endovascular grafts.

This study aims to gather real-world clinical data demonstrating the continued safety and performance of the a marketed stent graft (Zenith® Alpha Thoracic Endovascular Graft [ZTA]) and collect longer term follow-up to better understand clinical outcomes associated with the expected lifetime of the device.

The purpose of this study is to collect clinical data on patient outcomes, evaluate the safety and performance of AnkuraTM TAA Stent Graft System and SurpassTM Super Stiff Guidewire, and build clinical evidence for patients with Descending Thoracic Aneurysm (DTA) or Type B Aortic Dissection (TBAD).

The primary objective of ARISE II is to assess the safety and effectiveness of the GORE® Ascending Stent Graft device in the treatment of lesions involving the ascending aorta and aortic arch.

The goal of this observational study is to evaluate the Thoraflex Hybrid device alone and in combination with the RelayPro NBS stent-graft in the treatment of aortic disease affecting the aortic arch and descending aorta with or without involvement of the ascending aorta. Patients who undergo treatment with the Thoraflex Hybrid device with or without extension with a RelayPro NBS stent-graft will be eligible for enrolment and study activities and follow-up regime will follow standard care at each participating site. Participant involvement in the study will last for a total of 10 years from the point at which the Thoraflex Hybrid device is placed.

The ascending aorta conducts blood from the heart to the rest of the body. The ascending aorta can become enlarged, and the risk of tearing and rupturing becomes higher with larger aorta. When the ascending aorta tears or ruptures, the risk dying is high even if surgery is done as soon as possible. Traditionally, when the ascending aorta gets above 5.5 cm, surgery is recommended to replace the aorta. However, this threshold is based relatively weak evidence, and sometimes patients with smaller aorta can tear or rupture. On the other hand, surgery carries its own risk as well. Since there are risk of waiting or doing surgery, there is currently no great support for either approach for patients with a smaller aorta. In the TITAN SvS trial, patients with an ascending aorta between 5.0 to 5.5 cm is assigned by chance to the early surgery group, in which they will undergo replacement of aorta, or the surveillance group, in which they will be closely monitored. The chance of dying or suffer tearing or rupture of aorta between the two groups will be compared. The result of the trial will guide future practice for patients with enlarged ascending aorta. This is a prospective, multi-centre randomized control trial that compares the all-cause mortality, aneurysm-related aortic events, rate of stroke, and quality of life for those patients undergoing early elective ascending aortic surgery to those patients undergoing surveillance. Patients referred for an ascending aortic aneurysm that meets the inclusion criteria will be randomized to the early elective surgery group or the surveillance group. Recruitment will end when the desired sample size is reached, and the patients will be followed for a minimum 2-year period. The primary objective of the trial is to compare the composite outcome of the all-cause mortality and incidence of acute aortic events between surveillance and elective ascending aortic surgery for patients with degenerative or bicuspid valve-related ascending aortic aneurysm after 2 years of follow up. The hypothesis is that the early surgery group will have a significantly lower all-cause mortality and incidence of acute aortic events at 2 years of follow up compare to the surveillance group. The result of this trial will provide evidence based guidance in the appropriate management of ascending aortic aneurysm based on the size criteria, and establish a large database for future investigations.

Study Design This is a prospective, multicenter, non-randomized clinical study in patients presenting thoracic aortic pathologies. Following a baseline assessment, the implantation procedure will be performed according to the Instructions for Use and local routine practice. A follow-up visit will be performed 30 days, 6, 12,24 and 36 months after the implantation procedure. The investigator will perform assessments of the implantation procedure and device system and document adverse events (AE) and device deficiencies. Resources utilization and unit costs will be collected at index procedure and during follow-up. HRQoL is going to be investigated in this prospective study using the generic questionnaire EQ5D 5 levels, comparing pre- and postoperative scores. Study Objective The objective of the study is to evaluate the safety, performance and resource utilization associated with the use of GORE® TAG® Conformable Thoracic Stent Graft with ACTIVE CONTROL systems in humans having thoracic aortic pathologies. Safety will be evaluated considering mortality and morbidity variables (mainly focused on device related complications). Efficacy will be evaluated according to the variables related to the technical and clinical successes. In addition, resource utilization and associated costs will be collected prospectively with the objective to analyze differences in resource utilization between outcome groups, landing zone groups, disease severity groups, adverse event groups and case-mix groups. We will calculate the average marginal costs increase for complications when they occurred during TEVAR or surgical revascularization (e.g., paralysis, stroke, nerve injury, lymph damages, myocardial infarction, major bleeding event, respiratory complication). Resource utilization analysis is not going to be limited to the index procedure but will continue during follow-up. Subject Population: Elective and Urgent Thoracic aorta pathologies such as aneurysms, pseudoaneurysms, dissections, blunt thoracic aorta injury, penetrating ulcers and intramural hematoma. Planned number of patients: A total of 200 patients. Approx. 20 study centers in 2 European countries (15 in Italy and 5 in Spain) . A subgroup of 8centers will be selected for the micro-costing analysis (7 in Italy and one in Barcelona) Expected Time to Complete Enrollment: end of 2021 (18 months).

The main purpose of this study is to define the complex genetic and pathogenic basis of thoracic aortic aneurysm (TAA) and other forms of aortopathy and/or aortic valve disease by identifying novel disease-causing genes and by identifying important genetic modifiers for aortic and aortic valve disease severity.

This study aims to evaluate mid- and long-term outcomes after Thoracic endovascular aortic repair (TEVAR) with custom-made devices.
