Which structure is commonly seen in the ICE home view?

• A. Right Atrium
• B. Right Ventricle
• C. Left Atrium
• D. Left Ventricle

Answer: (A)

In intracardiac echocardiography, the catheter is advanced through the venous system into the right atrium, and the standard starting image—the home view—is taken from within the right atrium. This position provides a stable, reproducible view of RA structures and the interatrial septum, which is particularly useful for orienting to the heart and planning transseptal puncture to access the left heart. From this RA-centered view you can tilt to see the tricuspid valve and even the right ventricle, but to visualize left-sided structures you need to reposition and angle the beam across the septum. That makes the right atrium the structure most commonly seen in the ICE home view.
