Figure 6 Pulmonary Vein Anatomy Assessment With MDCT
Three-dimensional volume-rendered reconstructions of 64-slice MDCT scans to illustrate pulmonary vein anatomy. (A) Normal pulmonary vein anatomy is shown. Four pulmonary veins with separate insertions in the left atrium (LA) are present. (B to D) Variations in pulmonary vein anatomy. (B) A common ostium of the left-sided pulmonary veins is shown (arrows). (C) An additional right-sided pulmonary vein (arrow). (D) An aberrant insertion of the additional pulmonary vein is present (arrow). All of these anatomical variations in pulmonary vein anatomy may likely impact catheter ablation procedures. LIPV = left inferior pulmonary vein; LSPV = left superior pulmonary vein; MDCT = multidetector row computed tomography; RIPV = right inferior pulmonary vein; RSPV = right superior pulmonary vein.
