A 63-year-old diabetic woman was emergently submitted to coronary artery bypass grafting in the setting of acute myocardial infarction. Recurrent, drug-refractory episodes of ventricular arrhythmia occurred for 2 weeks postoperatively, despite no documentation of ongoing myocardial ischemia and optimum medical treatment. Ventricular arrhythmia was initiated by premature ventricular contractions originating from the Purkinje system within the infarct border zone. Radiofrequency catheter ablation was performed at sites where Purkinje potentials were recorded, leading to arrhythmia cessation. A week later, an implantable cardioverter defibrillator was inserted and she was discharged home a few days later. At 15-month follow-up, there were no further episodes of arrhythmia and ventricular function had improved.
