“…27 Based on the inverse principle, the clinical utility of non-invasive body surface mapping in atrial and ventricular arrhythmias has been reported. [28][29][30][31] Body surface mapping is undertaken by using a commercially available system (ECVUETM, Cardioinsight Technologies). After acquiring 64 section multi-detector CT images with a vest of 252 body-surface electrodes positioned on the thorax and upper abdomen, epicardial unipolar electrograms are reconstructed on a patient-specific biatrial geometry.…”

Atrial fibrillation (AF) is the most common rhythm disorder, and is strongly associated with thromboembolic events and heart failure. Over the past decade, catheter ablation of AF has advanced considerably with progressive improvement in success rates. However, interventional treatment is still challenging, especially for persistent and long-standing persistent AF. Recently, AF analysis using a non-invasive body surface mapping technique has been shown to identify localised reentrant and focal sources, which play an important role in driving and perpetuating AF. Non-invasive mapping-guided ablation has also been reported to be effective for persistent AF. In this review, we describe new clinical insights obtained from non-invasive mapping of persistent AF to guide catheter ablation.

“…Further in 92 % of cases, the mechanism of atrial tachycardia was accurately diagnosed. 27 In a feasibility study by Haissaguerre et al, ECGI was demonstrated to identify active sources of AF with high resolution. 28 Specifically, they demonstrated active sources in the vicinity of the pulmonary veins in patients with paroxysmal AF and more widespread sources in patients with the more sustained form of the arrhythmia.…”

Since the first catheter ablation for cardiac arrhythmia more than three decades ago, ablation technology has continually evolved at a rapid pace. Much of the early progress in the field was made in ablation of supraventricular tachycardias. Following a seminal study from Haïssaguerre et al. 1 in 1998, which demonstrated that pulmonary vein triggers are important sources of atrial fibrillation (AF), the approach to management of AF underwent a revolution. Electrical isolation of pulmonary veins (PVs) using catheter ablation became an established therapeutic strategy in patients with paroxysmal AF. During subsequent years, the role of ablation in AF expanded, and more extensive strategies involving ablation of non-pulmonary vein triggers and modification of the left atrial substrate were demonstrated to be effective, even in persistent forms of AF. New Technologies and Techniques for AF AblationCurrently, the most widely used technique for PV isolation involves delivery of point-by-point ablation lesions around the circumference of the vein. A number of different variations to the approach have been developed. During the early stages of PV isolation, a 'segmental approach' which involved targeting the earliest PV potentials at the ostium of the PV was commonly used. Due to high reconnection rates and the risk of PV stenosis, the technique has progressively been modified and the prevailing technique involves circumferential antral ablation to achieve PV isolation. AbstractCatheter ablation is an established treatment strategy for a range of different cardiac arrhythmias. Over the past decade two major areas of expansion have been ablation of atrial fibrillation (AF) and ventricular tachycardia (VT) in the context of structurally abnormal hearts. In parallel with the expanding role of catheter ablation for AF and VT, multiple novel technologies have been developed which aim to increase safety and procedural success. Areas of development include novel catheter designs, novel navigation technologies and higher resolution imaging techniques. The aim of the present review is to provide an overview of novel developments in AF ablation and VT ablation in patients with of structural cardiac diseases.

Abstract: This prospective multicenter series shows a high success rate of ECM in accurately diagnosing the mechanism of AT and the location of focal arrhythmia. Intraprocedural use of the system and its application to atrial fibrillation mapping is under way.
