The patient is a 44-year-old male who presents for a pulmonary vein CT prior to planned atrial fibrillation ablation by catheter-based pulmonary vein isolation. The quality of the study is suboptimal. There is a relatively low contrast opacification of the left atrium pulmonary veins. Within the limits of this study the pulmonary vein dimensions are as follows:Left superior pulmonary vein: 19.3 x 12.8mmleft inferior pulmonary vein 11.4 x 20.1 mmright superior pulmonary vein 26.6 x 17.2 mmright inferior pulmonary vein 19.5 x 15.6 mmLeft atrial volume 123 cc
1. Increased left atrial volume. 2. Mildly enlarged pulmonary vein diameter. 3. Poor opacification of the left atrium and pulmonary veins.Interpretation of the lungs and other soft tissues of the thorax and upper abdomen will be included in the radiologist report.
