Article Title: Identification and Characterization of Sites Where Persistent Atrial Fibrillation Is Terminated by Localized Ablation

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).

Figure Lengend Snippet: Left Atrial Anatomical Maps Illustrating Delivered Ablation Lesions Three-dimensional left atrial electroanatomic maps in (A) anteroposterior, (B) posteroanterior, (C) left anterior oblique, (D) right anterior oblique, and (E and F) lateral projections were generated using the CARTO system. Lesions within the maps are displayed as red spheres, which indicate sites of ablation.

Article Snippet: After transseptal puncture guided by fluoroscopy and intracardiac echocardiography, a 3-dimensional left atrial electroanatomic map (CARTO, Biosense Webster) was generated ( ).

Figure Lengend Snippet: Electroanatomical map of the left atrium in the PA projection displaying WACA radiofrequency lesions around the LSPV. LIPV = left inferior pulmonary vein; LSPV = left superior pulmonary vein; PA = paroxysmal atrial; WACA = wide-area circumferential ablation.

Article Snippet: The 3-dimensional electroanatomical mapping system (Ensite NavX; Abbott Inc, Chicago, IL) was used to create a high-density endocardial activation map with a high-density mapping catheter (Advisor HD Grid; Abbott Inc).
