Characterization of Pulmonary Vein Dimensions Using High-Definition 64-Slice Computed Tomography prior to Radiofrequency Catheter Ablation for Atrial Fibrillation

Figure 3

(a) Number of patients with a right middle pulmonary vein (RMPV), common left ostium (LCO), and common right ostium (RCO). Patients with AFib (atrial fibrillation) versus controls with SR (sinus rhythm). 𝑁 = number of patients; total number of patients in each group = 50. (b) Volume of left atrium after exclusion of the pulmonary veins and left atrial appendage. (b) Left atrial volume in controls and patients with AFib. (c) Left atrial volume indexed to body surface area (BSA) in controls and patients with AFib; ^∗𝑃<0.05.
