1 Incessant intraseptal ventricular tachycardia ablated utilizing extracorporeal membrane oxygenation and bipolar ablation  Ali B.A.K. Al-Hadithi, BA(Hons), Houman Khakpour, MD, Daniel Cruz, MD, PhD, Noel G. Boyle, MD, PhD, FHRS, Kalyanam Shivkumar, MD, PhD, FHRS, Jason S. Bradfield, MD, FHRS  HeartRhythm Case Reports  Volume 4, Issue 12, Pages (December 2018) DOI: /j.hrcr Copyright © 2018 Heart Rhythm Society Terms and Conditions

2 Figure 1 A: Right anterior oblique (RAO) fluoroscopy of catheter position at the time of bipolar ablation delivery. B: A 3-dimensional electroanatomic map of the septum. C: Left anterior oblique (LAO) fluoroscopy of catheter position at the time of bipolar ablation delivery. Blue star indicates left ventricular ablation catheter; yellow star indicates 8 mm nonirrigated catheter utilized for bipolar ablation across septum. D, E: The 2 clinical ventricular tachycardias (VTs) seen. F: Late potentials during sinus rhythm. Red circle indicates late potential. G: Mid-diastolic potentials during VT are shown; however, entrainment mapping demonstrated this site was a bystander. Blue circle indicates diastolic potential during VT. H: Early diastolic sites; bipolar ablation was delivered at this site and terminated the VT. Green circle indicates early diastolic potential during VT at successful bipolar ablation site. CS = coronary sinus. HeartRhythm Case Reports 2018 4, DOI: ( /j.hrcr ) Copyright © 2018 Heart Rhythm Society Terms and Conditions
