23 Clinical Trials for Various Conditions
The overall goal of this study is to develop and validate a preference assessment tool for patients who have severe aortic stenosis and are contemplating their treatment options. The first part of the study focuses on understanding the treatment goals and treatment features that matter most to patients who have already made the decision. The investigators use mixed methods (nominal group technique, card sorting) to elicit, prioritize, and organize these patient preferences into a "cognitive map". Based on those findings, the investigators design a preference tool and then pre-test the tool with patients and healthcare providers.
The purpose of the study is to investigate the safety and efficacy of transcatheter aortic valve implantation (TAVI) in patients with severe, symptomatic Aortic Stenosis (AS) at intermediate surgical risk by randomizing patients to either Surgical Aortic Valve Replacement (SAVR) or TAVI with the Medtronic CoreValve® System. Single Arm: The purpose of this trial is to evaluate the safety and effectiveness of transcatheter aortic valve implementation (TAVI) in patients with severe symptomatic Aortic Stenosis (AS) at intermediate surgical risk with TAVI. This is a non-randomized phase of the pivotal clinical trial.
The purpose of this trial is to generate clinical evidence on valve safety and performance of self-expanding (SE) versus balloon-expandable (BE) transcatheter aortic valve replacement (TAVR) in subjects with a small aortic annulus and symptomatic severe native aortic stenosis. Additionally, a stress echocardiography sub-study will be conducted as part of the SMART Trial at select sites. The purpose of the sub-study is to evaluate performance of SE versus BE TAVR in subjects with a small aortic annulus and symptomatic severe native aortic stenosis after undergoing exercise stress echocardiographic testing.
The purpose of this study is to collect clinical evidence on valve performance and procedural outcomes associated with an "optimized" TAVR care pathway and post-TAVR conduction disturbance pathway while using the Evolut™ PRO and Evolut™ PRO+ devices. The purpose of the addendum is to collect post-market clinical evidence on valve performance and procedural outcomes associated with the Evolut FX Device.
The Keystone Heart TriGuard™ HDH is an aortic embolism deflection device intended to reduce the amount of embolic material that may enter the carotid, subclavian, and vertebral arteries during transcatheter heart valve implantation. The objective of the study is to assess the safety and efficacy of the TriGuard™ HDH embolic deflection device in patients undergoing transcatheter aortic valve implantation (TAVI), in comparison with an active control group of patients undergoing unprotected TAVI. Subjects with indications for TAVI and who meet study eligibility criteria will be randomized 2:1 to one of two treatment arms: 1) Intervention: Embolic protection device (TriGuard™) with transcatheter aortic valve implantation or 2) Control: Unprotected transcatheter aortic valve implantation.
The investigators seek to determine the feasibility of assessing neurologic injuries subsequent to transcathether aortic valve replacement (TAVR). Such a model has been applied previously by the principal investigator to assess and improve neurologic outcomes for other cardiac surgical procedures. The investigators shall assess patients during the following intervals: pre-procedure, within 72-96 hours post-procedure, and 3 months post-procedure. Case videos will be established to assist in identifying and associating emboli (using transcranial Doppler) and processes of clinical care during the TAVR procedure. Neurologic injury will be assessed in the following ways: stroke (neurologic exam, NIH Stroke Scale), silent infarcts (diffusion-weighted MRI, diffusion-tensor imaging), and neurobehavioral deficits (a battery of neuropsychological tests). Secondly, the investigators will investigate changes in the apnea-hypopnea index (AHI), a measure of sleep-disordered breathing, before vs after surgery between those subjects who develop post-operative acute brain infarction and those who do not. The investigators hypothesize that subjects who develop acute brain infarction will have an increase in AHI between baseline and post-op measurements compared with those subjects who do not develop acute brain infarction. A research coordinator will coordinate the testing.
The study will evaluate all female patients with severe aortic stenosis undergoing transcatheter valve implantation with commercially available valves and delivery systems.
To evaluate the safety and feasibility of DurAVR™ THV System in the treatment of subjects with symptomatic severe native aortic stenosis.
To assess the safety and feasibility of Transcatheter Aortic Valve Replacement (TAVR) with commercially available bioprostheses in patients with severe, symptomatic aortic stenosis (AS) who are low-risk (STS score ≤3%) for surgical aortic valve replacement (SAVR).
To evaluate the safety and efficacy of the Medtronic CoreValve® System for the treatment of symptomatic severe aortic stenosis in subjects with significant comorbidities in whom the risk of surgical aortic valve replacement has a predicted operative mortality or serious, irreversible morbidity risk of ≥50% at 30 days.
The purpose of the study is to evaluate the safety and efficacy of the Medtronic CoreValve® System in the treatment of symptomatic severe aortic stenosis in subjects who have a predicted very high risk and high risk for aortic valve surgery.
The purpose of the study is to evaluate the safety and efficacy of the Medtronic CoreValve® System in the treatment of symptomatic severe aortic stenosis in subjects who have a predicted high risk for aortic valve surgery and/or very high risk for aortic valve surgery.
The purpose of this clinical study is to evaluate the acute safety and effectiveness of the next-generation Navitor (Portico™ NG) Transcatheter Aortic Heart Valve as assessed by the rate of all-cause mortality at 30 days and the rate of moderate or greater paravalvular leak at 30 days in a high or extreme surgical risk patient population to support CE (Conformité Européenne) Mark and FDA approval.
The purpose of this trial is to determine the safety and effectiveness of the Edwards SAPIEN 3 transcatheter heart valve and delivery systems which are intended for use in patients with symptomatic, calcific, severe aortic stenosis, and are in high risk.
The purpose of this trial is to determine the safety and effectiveness of the Edwards SAPIEN 3 transcatheter heart valve and delivery systems which are intended for use in patients with symptomatic, calcific, and severe aortic stenosis, and those with intermediate risk.
The purpose of this trial is to determine the safety and effectiveness of the Edwards SAPIEN XT transcatheter heart valve and delivery systems which are intended for use in patients with symptomatic, calcific, severe aortic stenosis.
This study will monitor the safety and valve performance of the Edwards CENTERA Transcatheter Heart Valve (THV) System in patients with symptomatic, severe, calcific aortic stenosis who are at intermediate operative risk for surgical aortic valve replacement (SAVR).
The Siegel™ Transcatheter Aortic Valve (TAVR) early feasibility study objective is to assess the acute and long-term safety and feasibility of the Siegel TAVR device in adult subjects with symptomatic, severe native aortic stenosis eligible for the transcatheter aortic valve replacement.
The TVT Registry™ is a benchmarking tool developed to track patient safety and real-world outcomes related to the transcatheter aortic valve replacement (TAVR) procedure. Created by The Society of Thoracic Surgeons (STS) and the American College of Cardiology (ACC), the TVT Registry is designed to monitor the safety and efficacy of this new procedure for the treatment of aortic stenosis.
The Sentinel System will be a safe and effective method for capturing and removing embolic material (thrombus/debris) during transcatheter aortic valve replacement in order to reduce the ischemic burden in the cerebral anterior circulation.
To collect information about treatment for severe aortic stenosis (AS), which affects the aortic valve in the heart. Aortic stenosis is a narrowing of the aortic valve opening, which decreases blood flow from the heart and causes symptoms such as chest pain, fainting and shortness of breath. The preferred treatment for severe aortic stenosis is aortic valve replacement surgery.
The purpose of this study is to determine the safety and effectiveness of the device and delivery systems (transfemoral and transapical) in high risk, symptomatic patients with severe aortic stenosis.
