Key result
Recurrent polymorphic VT and VF with ICD shocks are linked to higher mortality and hospital readmissions.
Why the study?
Recurrent VT/VF with ICD shocks in patients with PMVT and VF leads to decreased quality of life, hospital readmissions, and increased mortality despite effective ICD therapy.
This paper discusses the potential role of scar modification beyond trigger ablation for managing polymorphic ventricular tachycardia and ventricular fibrillation to reduce recurrent ICD shocks.
Answers are grounded in this paper and cite their sources.
Scar modification may adjunctively reduce PMVT/VF burden in SHD; leaves open comparative efficacy versus trigger ablation alone.
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.
