The Lazarus Protocol: Rescue Catheter Ablation of Incessant Ventricular Fibrillation by Purkinje Substrate Denetworking in Critically Ill Patients With Ischemic Cardiomyopathy.
We report a case series of 3 critically ill patients with refractory incessant ventricular fibrillation (VF) who underwent catheter ablation using high-density mapping of the Purkinje system during ongoing VF, combined with targeted Purkinje denetworking and myocardial substrate modification. All patients were supporte...
