Catheter-based intra-cardiac echocardiography (ICE) is an imaging modality similar to intra-vascular ultrasound (IVUS). It allows imaging inside the heart to visualize cardiac structures and blood flow using Doppler imaging. The standard-of-care for this type of imaging is usually transesophageal echo (TEE), but ICE proponents say the intra-cardiac modality has several advantages.
