Accurate substrate characterisation is important for depicting scar-related re-entrant tachycardia to optimise ablation targets and strategies. The underlying substrate can be analysed using electrogram (EGM) characteristics, such as low voltage, local abnormal voltage activity (LAVA), evoked potentials or late potentials, conduction analysis in sinus rhythm or differential pacing, or using…

Over the last 20 years ventricular tachycardia (VT) ablation has evolved from a treatment modality for selected patients withrecurrent haemodynamically tolerated VT (which can be mapped during ongoing arrhythmia), to a therapeutic option for patients with tolerated and untolerated VT using substrate-based ablation strategies.1 The substrate for VT after myocardial infarction (MI) consists of…

Scar-related reentrant ventricular tachycardia (VT) may be present in a variety of structural heart disease (SHD) phenotypes. In this setting, VT circuits are comprised of viable myocytes separated by fibrosis, allowing for the slow conduction needed to facilitate reentry.1,2 Aetiologies of fibrosis include ischaemic heart disease (IHD), inflammatory conditions, infiltrative cardiomyopathy,…

Catheter ablation has been increasingly used as a treatment for refractory ventricular tachycardia (VT) in patients with non-ischaemic cardiomyopathy (NICM). However, ablation outcomes tend to be quite variable because of the heterogeneity of the aetiology for the NICM and associated VT substrate in these patients.1–3 Patients with NICM can be sub-classified based on specific genotypic and…

Recurrent ventricular tachycardia (VT) in patients who have an implantable cardioverter-defibrillator (ICD) with subsequent shocks is associated with reduced quality of life and an adverse prognosis. Pharmacological treatments are associated with significant side-effects. Catheter ablation has been used to reduce the number of ICD therapies in patients with ischaemic and non-ischaemic…
