Scar modification for polymorphic ventricular tachycardia and ventricular fibrillation: hope beyond trigger ablation?

Authors: Hongtao Liao, Roderick Tung

Abstract

Polymorphic ventricular tachycardia (PMVT) and ventricular fibrillation (VF) are a common cause of sudden cardiac death in patients with structural heart disease (SHD) and occur less frequently in patients without any identifiable structural or metabolic disease which is defined as idiopathic PMVT/VF. Even though implantable cardiac defibrillator (ICD) therapy is highly effective for aborting sudden cardiac death, recurrent ventricular tachycardia (VT)/VF with subsequent ICD shocks are associated with decreased quality of life, hospital readmissions, and increased mortality.
