The purpose of this study is to evaluate the imaging performance and procedural safety of a prototype 4D ICE catheter during real-time intracardiac imaging and to optimize device imaging parameters, compared with current standard imaging modalities. TEE is the current standard of care and will serve as the primary imaging modality for clinical guidance during the EP and Structural Heart Disease (SHD) procedures. In this research protocol, TEE is not being investigated. ICE will be used as an adjunct imaging modality for research data collection and workflow evaluation only. All procedures will be performed using commercially available, FDA-approved Watchman devices, and no investigational implantable devices will be used. The use of ICE in this study does not modify the approved therapeutic device indication, implantation technique, or standard clinical decision-making.
This study is a prospective clinical feasibility study designed to evaluate the imaging performance, workflow efficiency, and safety of a prototype 4D intracardiac echocardiography (ICE) catheter (ACUNAV Luxera) used in conjunction with the Siemens Premium CV ultrasound system during cardiac interventional procedures. The ACUNAV Luxera 4D ICE system will be used adjunctively while standard-of-care transesophageal echocardiography (TEE) serves as the primary imaging modality. The study aims to determine whether 4D ICE provides comparable image quality and measurement accuracy to TEE, while maintaining procedural safety and enabling optimization of intracardiac imaging workflows.

RECRUITINGFeasibility of 4D ICE Imaging Performance
A composite score evaluating the overall technical and clinical adequacy of the 4D Intracardiac Echocardiography (ICE) catheter compared to standard-of-care imaging. The composite score is derived from three individual component assessments: Image Quality: Clarity, resolution, and artifact presence. Anatomical Visualization: Ability to clearly identify target cardiac structures. Procedural Guidance: Effectiveness of real-time images in guiding the procedure. Each component is graded by independent reviewers on a 5-point Likert scale (1=Inadequate, 2=Suboptimal, 3=Adequate, 4=Good, 5=Excellent). The final composite score is calculated as the sum of the three component scores, ranging from a minimum of 3 (worst performance) to a maximum of 15 (best performance).
