Does radiofrequency catheter ablation prevent ventricular fibrillation in a patient with idiopathic ventricular fibrillation triggered by a monofocal premature ventricular complex?
Catheter ablation targeting a culprit premature ventricular complex of monofocal origin may be an effective option for preventing the recurrence of idiopathic ventricular fibrillation.
A 62 year old man was admitted for evaluation of recurrent episodes of syncope. A surface ECG showed frequent repetitive premature ventricular complexes of right ventricular outflow tract origin. Ventricular fibrillation was inducible by programmed electrical stimulation but otherwise cardiac evaluation was unremarkable. A diagnosis of idiopathic ventricular fibrillation was made and an implantable cardioverter-defibrillator (ICD) was installed. However, spontaneous ventricular fibrillation recurred, requiring repeated ICD discharges. The ventricular fibrillation was reproducibly triggered by a single premature ventricular complex with a specific QRS morphology. Radiofrequency catheter ablation was carried out to eradicate this complex. No ventricular fibrillation has developed after this procedure, and the patient does not require drug treatment.
Seiji Takatsuki (Sun,) conducted a case report in Idiopathic ventricular fibrillation (n=1). Radiofrequency catheter ablation was evaluated on Recurrence of ventricular fibrillation or ICD shock. Radiofrequency catheter ablation successfully eradicated the monofocal premature ventricular complexes triggering idiopathic ventricular fibrillation, with no recurrence of ventricular fibrillation or ICD shocks over 20 months.
