Figure Lengend Snippet: Figure 1. Acute termination in patients with persistent atrial fibrillation (AF) by first ablation at sites marked (*). A, Acute termination of AF in a 60-y-old man to sinus rhythm by ablation, depicted on the electroanatomic right atrial shell (i). B, Acute termination of AF in a 61-y-old with the first ablation lesion applied in the left atrium (ii). This study was designed to investigate these scenarios. IVC indicates inferior vena cava; LA indicates left atrium; LSPV, left superior pulmonary vein; RA, right atrium; and SVC, superior vena cava.

Article Snippet: In each case, a region of interest, identified prospectively by mapping of repetitive activation and phase patterns,11 was targeted for radiofrequency ablation by applying contiguous lesions in localized areas of <3 to 4 cm2.10,13 The location of each ablation site was referenced to known electrodes, and their anatomic locations were verified by 3-dimensional electroanatomic imaging (NavX, St Jude Medical, St Paul, MN; Carto, Biosense-Webster, Diamond Bar, CA).
