Title. Three-dimensional endocardial surface of the left atrial and right atrial structures and locations of bi-atrial ablation points
Caption. Red, pink and white points indicate the locations of ganglionated plexi based on fragmented electrograms. Intracardiac electrograms are seen during ablation on the posteromedial left atrial ganglionated plexus via coronary sinus at the bottom of video. Mobitz type 1 atrioventricular block completely resolves during radiofrequency ablation in this site.
