3D volume renderings of the ablation lesions. 3D volume renderings of the classified enhancement (in blue—obtained from a 3 months post-ablation LGE CMR data-set) overlaid upon the segmented and 3D rendered left atrial blood-pool (LABP, in semi-transparent yellow). The segmented and 3D rendered aorta is also displayed in red. The left-hand side image is the right view of the left atrium (LA) when the body is in vertical position, while the right-hand side image is the left view of the LA when the body is in prone position. Enhancement distribution comprised encirclement of each ipsilateral pair of pulmonary veins at their antra, as well as a linear pattern at the mitral isthmus, as might be expected by the respective ablation techniques. RSPV right superior pulmonary vein, RIPV right inferior pulmonary vein, LSPV left superior pulmonary vein, LIPV left inferior pulmonary vein, LAA left atrial appendage
