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…

Since the introduction of electroanatomical mapping (EAM) into clinical practice in 1997, remarkable progress has been made in catheter infrastructure, signal recording and processing, catheter guidance and visualisation and simultaneous real-time depiction and processing of different types of critical information during an ablation procedure.1 The latter, along with the comprehension of the…

Adecade after its first description as ‘the electrophysiological substrate’ of atrial fibrillation,1 mapping complex fractionated atrial electrogram (CFAE) as an ablation target for atrial fibrillation (AF) remains highly controversial. Early high-density mapping studies of induced AF in humans revealed distinct mechanisms that underlie electrogram fractionation: collision areas of distinct…

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…

With an ageing population and widespread use of implantable cardioverter-defibrillators, physicians are confronted with an increasing number of patients with symptomatic, drug-refractory ventricular tachycardia (VT). Catheter ablation is an important treatment option in the management of patients with structural heart disease and VT.1,2 In many patients, VT can be successfully ablated from the…
