Cardiac perforation during atrial septal puncture (ASP) might be avoided by improved
image guidance. X-ray fluoroscopy (XRF), which guides ASP, visualizes tissue poorly
and does not convey depth information. Ultrasound is limited by device shadows and
constrained imaging windows. Alternatively, real-time MRI (rtMRI) provides excellent
