1 Cryoballoon pulmonary vein isolation and voltage mapping for symptomatic atrial fibrillation 9 months after Watchman device implantation  Henry D. Huang, MD, Viren M. Patel, MD, Parikshit S. Sharma, MD, Zenith Jameria, MD, Sorin Lazar, MD, Richard Trohman, MD, Erik Wissner, MD, PhD  HeartRhythm Case Reports  Volume 4, Issue 1, Pages 6-9 (January 2018) DOI: /j.hrcr Copyright © 2017 Heart Rhythm Society Terms and Conditions

2 Figure 1 A: Left anterior oblique (LAO) view of the patient's existing Watchman device and Achieve circular mapping catheter positioned within the left superior pulmonary vein. B: LAO view following inflation of the 28 mm cryoballoon at ostium of the left upper pulmonary vein and contrast injection showing adequate seal. Black arrows indicate Watchman device; white arrow indicates inflated cryoballoon. HeartRhythm Case Reports 2018 4, 6-9DOI: ( /j.hrcr ) Copyright © 2017 Heart Rhythm Society Terms and Conditions
