Successful ablation of Purkinje ectopy-triggered ventricular fibrillation storm in a patient with orthotopic heart transplantation and severe SARS-CoV-2 pneumonia: a case report.

ABSTRACT:

Background

Catheter ablation is one of the most effective treatment options for patients with drug-refractory, scar-related monomorphic ventricular tachycardia (VT). In selected cases, catheter ablation also plays an important role in treatment of polymorphic VT (PMVT) and/or ventricular fibrillation (VF). Rarely, premature ventricular contractions (PVCs) originating from the Purkinje network can induce PMVT/VF. Ablation and elimination of these PVCs can prevent VF recurrences.

Case summary

A 41-year-old patient with a history of orthotopic heart transplantation (HTX) 8 years before admission and newly diagnosed SARS-CoV-2 pneumonia was referred to our centre after experiencing several episodes of drug-refractory VF. An electrophysiological study showed ectopy-triggered VF o
