Stroke Clinical Trial - Use of 4D-ICE in Conjunction With TEE for Left

Status Recruiting

Clinical Trial Summary

This is a prospective, single center, non-randomized study with two parallel arms intended to study if 4D Intracardiac echocardiography (4D-ICE) (Nuvision, Nuvera TM) will provide better visualization of the anatomical landmarks from the larger imaging volume and provide optimal intra procedural guidance similar to Transesophageal echocardiography (TEE) (GE 6VT-D ULTRASOUND TRANSDUCER) for Left atrial appendage closure (LAAC). The study will enroll approximately 52 subjects and will be followed through 12 months.

Clinical Trial Description

Standard intraprocedural guidance for transcatheter left atrial appendage closure (LAAC) employs a multi-modality integrated approach combining fluoroscopy for guiding the delivery system, and transesophageal echocardiography (TEE) for intracardiac characterization to guide device selection and monitor procedural complications. Successful implantation of the device is confirmed with contrast-enhanced fluoroscopy and color doppler flow imaging on TEE. TEE is the current gold standard for procedural guidance but requires general anesthesia (GA) to avoid patient motion and discomfort during the procedure. General anesthesia, however, is associated with pulmonary complications and patient discomfort due to endotracheal intubation. Intraprocedural LAAC guidance under local anesthesia or conscious sedation might help mitigate these GA-related disadvantages and has motivated multiple clinical studies, establishing intracardiac echocardiography (ICE) as a safe and feasible alternative to TEE. The new generation of NuVision ICE catheter offers a larger imaging volume of 90° x 90° with multiplanar reformatted (MPR) echo views for better visualization of anatomical landmarks and procedural guidance and aid in sizing of the device. This has a potential to improve outcomes and reduce procedure times while lowering healthcare costs. In this study, Role of NuVision Intracardiac Echocardiographic (ICE) catheter with Tranesopheal echocardiography (TEE) in predicting intra-procedural outcomes and success of implantation in patients undergoing left atrial appendage occlusion will be assessed. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
