Filter by:Study design: single arm, interventional and multicenter study. The objectives are evaluate Safety and efficacy of TAVI in Department of Cardiology without on site cardiac Surgery for symptomatic severe aortic valve stenosis by expert operator team, in patients with prohibitive surgical risk. For the pilot phase, 20 patients will be enrolled. For whole study, all consecutive patients undergoing TAVI in center without CS on site will be enrolled to reach a number of about 200 patients.
The goal of this prospective, multi-center, randomized, controlled study is to compare the safety and efficacy of the ProtEmbo Cerebral Embolic Protection device to a hybrid control (no embolic protection device ('No Device') and the Sentinel device) in subjects with severe symptomatic native aortic valve stenosis indicated undergoing a TAVR procedure.
The goal of this clinical trial is to learn about the safety and performance of the F2 device for cerebral embolic protection in participants with symptomatic aortic stenosis underdoing a Transcatheter Aortic Valve replacement procedure. Participants will complete several neurocognitive assessments and an MRI procedure.
Anesthetic agents can cause hypotension, and be especially dangerous in patients with severe aortic stenosis, which can lead to even circulatory collapse. Remimazolam is known for its hemodynamic stability compared to propofol. This study is designed to compare effects of remimazolam vs. sevoflurane anesthesia on intraoperative hemodynamics in patients with severe aortic valve stenosis.
The purpose of this clinical trial is to evaluate the safety and efficacy of the Prizvalve Pro™ transcatheter aortic valve system in the treatment of patients with severe aortic stenosis who are at high risk of surgery or who are not suitable for surgery.
To assess the efficacy and safety of Intravascular Lithotripsy (IVL) in subjects undergoing transfemoral TAVR in patients with severe iliac disease, prohibitive for transfemoral TAVR in patients with severe symptomatic aortic stenosis, otherwise considered for alternative access TAVR. (e.g. trans-carotid)
The goal of this study is to learn about the effectiveness of TAP block for pain relief after vascular surgery on the abdominal aorta. The main question the investigators are looking to answer is whether the TAP block lowers the dose of opioid required after abdominal aortic surgery.
The goal of this non-interventional, retrospective data analysis is to validate the circle method for patients with bicuspid aortic heart valves undergoing transcatheter aortic heart valve implantation (TAVI). The main aims are: - to assess whether patients with bicuspid aortic valves that received a TAVI suffered from fewer complications - if valve size was identical to the one determined using the circle method compared to - a case where circle method derived valve size is different from the actually implanted valve - to develop recommendations on how to size the valve using the circle method.
The EMPIRE II study evaluates the safety and performance of the entire ALLEGRA THV System. The primary safety endpoint is composite of all-cause mortality or stroke rates at 12 months. And the primary performance endpoint is device success at 7 days. Based on the outcomes of a study with a similar device and considering a drop-out rate of 5%, 177 patients need to be enrolled in the study.
Combining routine preoperative CT imaging with patient-specific computer modelling predicts the interaction between different sizes of transcatheter aortic valve replacement devices at different implantation depths and the patient's unique anatomy (including post-implantation deformation) allowing preoperative evaluation of the risk for paravalvular leakage and conduction disorders. The objective of this randomized controlled trial is to evaluate whether pre-operative CT-imaging with advanced computer modelling and simulation (FEops HEARTguide™) adequately predicts procedural outcomes in TAVR procedures, whether it leads to changes of preoperative decisions and whether or not this leads to improved outcome in TAVR procedures.
