15 Clinical Trials for Various Conditions
This single-center, prospective, randomized study will evaluate the safety and feasibility of Intracardiac echocardiography (ICE)-guided Left atrial appendage closure (LAAC) when compared to the traditional Transesophageal echocardiography (TEE) approach.
LAAOS-4 aims to determine if catheter-based endovascular left atrial appendage occlusion prevents ischemic stroke or systemic embolism in participants with atrial fibrillation, who remain at high risk of stroke, despite receiving ongoing treatment with oral anticoagulation.
The purpose of this research is to to assess the feasibility and safety of left atrial appendage (LAA) occlusion with the WATCHMAN FLX™ device using a standardized intra-procedural intracardiac echocardiography (ICE) protocol under moderate sedation for procedural guidance.
Comparison among three different antithrombotic strategies after percutaneous LAA occlusion with a Watchman FLX LAAC device.
The Left Atrial Appendage Occlusion Registry (LAAO Registry™) is designed to assess the prevalence, demographics, management, and outcomes of patients undergoing percutaneous and epicardial based left atrial appendage occlusion procedures to reduce the risk of stroke. Patient-level data will be submitted by participating hospitals on a quarterly basis to the American College of Cardiology Foundation's National Cardiovascular Data Registry (NCDR). The primary aims of the LAAO Registry are to optimize the outcomes and management of patients through the implementation of evidence-based guideline recommendations in clinical practice, facilitate efforts to improve the quality and safety for patients undergoing percutaneous and epicardial based left atrial appendage procedures, investigate novel quality improvement methods and provide risk-adjusted assessment of patients for comparison with nationwide NCDR data. The secondary purpose of the LAAO Registry is to serve as a rich source of clinical data to support assessments of short- and long-term safety, comparative and cost effectiveness research, and as a scalable data infrastructure for post market studies.
Atrial fibrillation (AF) is the most common cardiac rhythm disorder in clinical practice. In the last two decades the number of hospitalizations for AF has increased two- to three-fold. More than 6 million people worldwide suffer from atrial fibrillation (AF), a cardiac disorder that results in systemic emboli. Patients with AF are 5 times more likely to have a stroke compared with those without AF. This registry will collection information on two devices that are used to treat AF. The WATCHMAN and LARIAT. The differences in techniques and subsequent effects of the two devices on outcomes related to AF has not been studied. This study will look to compare the two devices to see how the outcomes may vary.
The proposed work seeks to further understand the effects of LAA occlusion on cardiac structure and function, and in homeostasis. Numerous studies have implicated the left atrial appendage (LAA) as the source of the vast majority of left atrial thrombi in the setting of AF3. The University of Pittsburgh Medical Center will be implanting a Left Atrial Appendage filter system (the WATCHMAN® Left Atrial Appendage Filter System, manufactured by Atritech, Inc.). We aim to follow these patients for six months post implant in order to assess their heart rhythm, function, and to do blood tests to evaluate for neurohormonal changes.
The purpose of this study is to evaluate the performance of the Cardioblate Closure Device to occlude the LAA
We use a tiny catheter through the heart to separate the pericardium with gas. We expect this to improve the safety of the Lariat procedure.
The APPEND-CT registry is an investigator-driven multicenter retrospective observational database intended to compile cardiac CT follow-up data after Watchman FLX device implantation and function as a platform for answering clinical and research questions within LAAC follow-up. The derived studies should support therapeutic decision-making, improve risk-stratification in LAAC and help generate hypotheses for potential future clinical intervention trials.
The purpose of this research is to learn more about the normal care of patients with a new or pre-existing diagnosis of atrial fibrillation (AF). These abnormal and irregular heartbeats place patients at increased risk of developing clots in their bloodstream that could potentially lead to stroke. Normal care is designed to help prevent this from happening and to lessen or eliminate the symptoms patients may have. There are many different types of AF as well as numerous ways in which a variety of patients are treated. The investigators are interested in gathering more information to better keep track of patient treatment patterns (trends) that may differ from physician to physician, hospital to hospital, medication to medication, patient to patient and if necessary, procedure to procedure.
The primary objective is to demonstrate the safety and efficacy of the implantation of the LAmbre PlusTM device in patients with large or irregularly shaped appendages with non-valvular atrial fibrillation who are at increased risk for stroke and systemic embolism compared to oral anticoagulation (OAC).
The investigators thought to evaluate the safety and feasibility of peri-device leakage closure after left atrial appendage occlusion (LAAO, either surgical or interventional) with different devices.
This is a multi-center, prospective, randomized study, stratified by center, comparing the WATCHMAN device to long term warfarin therapy, demonstrating that the treatment arm is non-inferior to the control arm. This study was amended to allow for a non-randomized arm and increased enrollment.
This is a feasibility study to assess the safety and efficacy of the AtriCure AtriClip when placed via Minimally Invasive Surgical Deployment to the Left Atrial Appendage. The purpose is for evaluation of Stroke Prevention in Patients with Non-Valvular Atrial Fibrillation who are unable to take Oral Anticoagulants.
