Video Summary

Dr. Steven Filby, an interventional cardiologist, spoke about the importance of imaging in left atrial appendage closure procedures. He highlighted the use of CT (computed tomography) as a superior modality for pre-procedural planning compared to TEE (transesophageal echocardiogram). CT provides better visualization of the left atrial appendage and its surrounding structures, allowing for accurate device selection and positioning. Dr. Filby also discussed the use of ice (intracardiac echocardiography) during the procedure, which provides real-time imaging and helps assess device placement and any leaks.<br /><br />He emphasized the advantages of CT imaging, including improved procedural efficiency, accuracy, and patient satisfaction. CT-guided procedures also enable same-day discharge, which has been shown to be safe and cost-effective. Dr. Filby mentioned that CT is gaining traction in the field but still faces some barriers, including lack of familiarity and training among physicians.<br /><br />In terms of post-procedural imaging, Dr. Filby stated that CT is emerging as an important modality for surveillance, but TEE remains the gold standard. He discussed the assessment of device position, thrombus formation, peridevice leaks, and the need for systematic evaluation of CT images. Dr. Filby concluded by highlighting ongoing research to compare CT and TEE and the potential for AI-assisted CT platforms to further enhance imaging and workflow in left atrial appendage closure procedures.
