(FIT)-Module 6 Lectures: Special Technology Sessions-Use of Intracardiac Ultrasound in Electrophysiology Procedures (Hutchinson)

Video Transcription

Video Summary

In this presentation from Core Concepts 2022, the focus was on the use of intracardiac ultrasound (ICE) in electrophysiology (EP). Topics covered included basic imaging concepts, catheter designs, and the application of both two-dimensional and four-dimensional ICE probes. Key areas discussed were how to obtain ICE imaging views from the atrium and ventricle, and using ICE in procedures like atrial ablation, left atrial appendage occlusion, and ventricular ablation.<br /><br />The talk emphasized the importance of understanding ecophysics and optimizing ultrasound imaging, balancing between seeing more tissue and getting better resolution. Different ICE systems were reviewed, highlighting their historical and clinical applications. The phased array probes with their versatile imaging capabilities were particularly noted for their importance in detailed cardiac imaging.<br /><br />The presentation also addressed the integration of ICE with electroanatomical mapping, which helps create three-dimensional heart geometries and aids in mapping procedures while reducing fluoroscopic exposure. The role of ICE in guiding specific procedures, such as transseptal catheterization and cryoablation for atrial fibrillation, was also discussed.<br /><br />Furthermore, clinical applications were illustrated through examples and board-style questions, helping clarify how ICE can prevent complications, detect arrhythmia substrates, and monitor heart function during interventions. The presentation demonstrated how ICE not only enhances anatomical understanding but also supports safer and more effective EP procedures.
