Dynamic voltage mapping of the ventricular tachycardia substrate Open
Background Substrate mapping techniques that predict ventricular tachycardia (VT) isthmus components in sinus or paced rhythm are necessary as mapping during VT is often not possible. Voltage maps lack accuracy in differentiating scar, tra…

Durability of thermal pulmonary vein isolation in persistent atrial fibrillation assessed by mandated repeat invasive study Open
PVI durability may be poor in those with significant LA scarring and dilatation, even with modern thermal ablation technologies. RF resulted in significantly better PVI durability than did CB in this complex population.

Delineating postinfarct ventricular tachycardia substrate with dynamic voltage mapping in areas of omnipolar vector disarray Open
DVM, guided by areas of omnipolar vector disarray, allows for individualized postinfarct ventricular substrate characterization. Tissue bordering areas of disarray may harbor greater arrhythmogenic potential.

Silent pulmonary veins at redo ablation for atrial fibrillation: Implications and approaches Open
Background Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. Despite promising success rates, redo ablation is sometimes required. At redo, PVs may be found to be isolated (silent) or reconnected. We s…

98 Predictors of the need for pace & ablate in patients undergoing repeat catheter ablation for atrial fibrillation Open
Introduction A 'Pace & Ablate' strategy may be required after failed catheter ablation for atrial fibrillation (AF). We sought to determine which factors may predict the requirement for Pace & Ablate following redo ablation. Methods We ana…

An approach to help differentiate postinfarct scar from borderzone tissue using Ripple Mapping during ventricular tachycardia ablation Open
Background Ventricular scar is traditionally highlighted on a bipolar voltage (BiVolt) map in areas of myocardium <0.50 mV. We describe an alternative approach using Ripple Mapping (RM) superimposed onto a BiVolt map to differentiate posti…
