Does magnetocardiography accurately localize intracardiac electrophysiology catheters compared to fluoroscopy and MRI in patients undergoing electrophysiological study?
Magnetocardiography provides accurate and reproducible 3D localization of intracardiac catheters, offering a potential nonfluoroscopic imaging alternative for high-resolution endocardial mapping.
Fenici et al. (1998) conducted an observational in Patients undergoing routine electrophysiological study (n=5). Magnetocardiography (MCG) vs. Biplane fluoroscopy (XR) and MRI was evaluated on Accuracy of MCG localizations evaluated by anatomic location in MRI and mismatch with XR. Magnetocardiography accurately localized amagnetic catheters with a mean three-dimensional mismatch of 6 +/- 2 mm compared to fluoroscopy, demonstrating high reproducibility.
