A balloon occlusion technique to overcome the convective warming effect of coronary sinus blood flow on cryoablation Soledad Ascoeta, MD, Marc Dubuc, MD, Katia Dyrda, MD, MSc, Paul Khairy, MD, PhD HeartRhythm Case Reports Volume 1, Issue 6, Pages 442-444 (November 2015) DOI: 10.1016/j.hrcr.2015.06.006 Copyright © 2015 Heart Rhythm Society Terms and Conditions

Figure 1 The site of earliest atrial activation during tachycardia is indicated by the asterisk on the electroanatomic map in Panel A and the fluoroscopic image in Panel C. Of note, in Panel B, CS venography was not performed during cryoablation, such that the cryocatheter had migrated lateral to the site of origin of the atrial tachycardia (See text for details). CS = coronary sinus; IVC = inferior vena cava; SVC = superior vena cava; TV = tricuspid valve.
