Illustration of derivation of pulmonary vein encirclement (PVE) measurement. The left atrial shell is thresholded at 3.3 standard deviations above the blood pool mean, with scar shown in red and healthy atrial myocardium in blue. a antero-superior view and b postero-lateral view of left atrium. The computed route of the pulmonary vein (PV) encirclement is shown in yellow dashed line, whilst detected gaps in the ablation line are shown in white. For this acquisition, the PV encirclement (PVE) for the right sided veins was 98.5%, and for the left was 81.5%. (LAA: left atrial appendage, LSPV: left superior PV, LIPV: left inferior PV, RSPV: right superior PV, RIPV: right inferior PV)
