Acute Post-Ablation Imaging (Top 4 panels) Multiplanar reconstruction of pseudo-3D T2-weighted MR acquisition, demonstrating location of edema (white arrows) at cavotricuspid isthmus following ablation. Red dots indicate location of RF energy delivery calculated using active tracking. (Bottom 3 panels) Gadolinium-enhanced imaging for a single human subject following successful ablation. Dashed white arrow indicates cavotricuspid isthmus location, and time in min follows gadolinium administration. Regions of early no-reflow (dark) at 1 min become progressively more enhanced over the subsequent 18 min with slow uptake of gadolinium, then sequestration within the increased extracellular space, related to RF lesions. Ao = aorta; RA = right atrium; RF = radiofrequency; other abbreviations as in Figure 2.
