Figure 2 Automated Quantification of Chronic LA Injury 3 Months After PVAI

Left atrial wall injury was determined using a threshold based on the defined normal wall regions. Panels 1 to 16 show extent of injury at 5 standard deviations in a subset of slices from the 3D DE-CMRI from Patient #1 (Fig. 1). Reconstruction in 3D of the full set of data is shown in the right panels (3D PA and RL views). Using these methods, LA injury volume can be determined and calculated as a percentage of total LA wall volume. PA = posterior-anterior; RL = right-left; other abbreviations as in Figure 1.
