This image was obtained using IntraCardiac Echocardiography (ICE). For this imaging, a venous approach was used with the ultrasound probe positioned in the right atrium, looking through the interatrial septum, positioned at 12 o’clock in the accompanying diagram.

Interventional cardiologists routinely place the ICE probe in the right atrium to guide transseptal puncture and various percutaneous interventions, including left heart catheter ablation, left atrial appendage (LAA) closure/exclusion, and percutaneous mitral valvuloplasty. ICE provides direct visualization of the interatrial septum (visible at 12 o’clock on our ICE image) and is an invaluable tool to guide a safe transseptal puncture.1, 2

This crisp ICE image was acquired using IMMR’s state-of-the-art St Jude ViewFlex™ ICE 9-French catheter and Zonare ViewMate™ Z Intracardiac Ultrasound console.
