CMR versus invasive electro-physiology. Juxtaposition of the left atrial wall tissue classified as ‘‘pre-existent fibrosis’’ [left, in gray—obtained from a baseline LGE CMR scan and projected onto the segmented left atrial blood-pool (LABP), shown in pink] and the registered bipolar voltage map [middle—measured with a NavX EAM system: healthy left atrial wall tissue is showing in purple, while gray represents low voltage tissue]. The body illustration in the right-hand side image serves to clarify that the other two images refer to posteroanterior (PA) views of the left atrium (LA). CMR scar map compares well to the corresponding endocardial bipolar voltage map
