Fig. 2From: Anatomical correlation between left atrium pulmonary vein ablation targets of atrial fibrillation and adjacent bronchi and pulmonary arteries by MSCTMeasurement of the left atrium (LA) size and diameters of the pulmonary vein (PV) with multi-slice spiral CT. a, b Maximum diameters of the LA in coronal and sagittal views, respectively. LA1: transverse diameter; LA2: vertical diameter; LA3: anterior and posterior diameter. c Three dimensional images of the LA and four PVs. d Maximum upper and lower diameters of the four PVs measured at the coronary view. RSPV, right superior PV; RIPV, right inferior PV; LSPV, left superior PV; LIPV, left inferior PVBack to article page
