HeartRhythm Case Reports First experience with hybrid thoracoscopic ablation and noncontact dipole density mapping in the setting of long-term persistent atrial fibrillation Thiago Guimarães Osório, MD, Erwin Ströker, MD, Juan Sieira, MD, PhD, Gian-Battista Chierchia, MD, PhD, Carlo de Asmundis, MD, PhD, FHRS HeartRhythm Case Reports DOI: 10.1016/j.hrcr.2019.02.012 Copyright © 2019 Heart Rhythm Society Terms and Conditions

Figure 1 A 6-lead electrocardiogram (10 mm/mV, 25 mm/s) showing conversion to sinus rhythm during radiofrequency (RF) clamping of the right inferior pulmonary vein with a bipolar RF clamp.

Figure 2 Propagation history maps (posteroanterior view). A: The initial mapping showed a gap with activation passing through the left atrial posterior wall (LAPW). B: Postablation mapping of the gap showed isolation of the LAPW. Three red dots indicate radiofrequency points. LIPV = left inferior pulmonary vein; LSPV = left superior pulmonary vein; RIPV = right inferior pulmonary vein; RSPV = right superior pulmonary vein.
