“…Data derived from single-centre experience, multicentre prospective studies and registries have shown a success rate ≥90 % and a low rate of complications (≤ 5 %). [64][65][66][67][68][69][70][71] However, fatal complications related to the procedure have been communicated.…”

“…Lu et al reported 0.16 % mortality associatedwith WPW ablation (4/2,527 in an 11-year period) 11. More recently, one death due to embolism in a patient with Ebstein's anomaly was reported in 4,603 AP ablations (0.08 %) by the First Latin American Catheter Ablation Registry 71. The result of prophylactic catheter ablation in asymptomatic patients was first evaluated in a randomised clinical trial of patients from two centres in 2003 26.…”

Debate about the best clinical approach to the management of asymptomatic patients with ventricular pre-excitation and advice on whether or not to invasively stratify and ablate is on-going. Weak evidence about the real risk of sudden cardiac death and the potential benefit of catheter ablation has probably prevented the clarification of action in this not infrequent and sometimes conflicting clinical situation. After analysing all available data, real evidence-based medicine could be the alternative strategy for managing this group of patients. According to recent surveys, most electrophysiologists invasively stratify. Based on all accepted risk factors - younger age, male, associated structural heart disease, posteroseptal localisation, ability of the accessory pathway to conduct anterogradely at short intervals of ≤250 milliseconds and inducibility of sustained atrioventricular re-entrant tachycardia and/or atrial fibrillation - a shared decisionmaking process on catheter ablation is proposed.

“…Radiofrequency ablation (RFA) aiming at the electrical isolation of the pulmonary vein (PV) is more effective in controlling the rhythm than drugs, especially in young individuals with symptomatic paroxysmal atrial fibrillation (AF) without structural heart disease. 1 - 3 Electrical isolation is performed with point-by-point RFA around the PV, constituting a complex and lengthy procedure. 2 , 3 Recently, technologies have been developed aiming to simplify PV isolation, among them the balloon cryoablation.…”

Although the exact circuit of atrioventricular nodal re-entrant tachycardia (AVNRT) still eludes us, AVNRT is the most common regular arrhythmia in humans, and therefore the most commonly encountered during ablation attempts for regular tachycardias. [1][2][3][4] Catheter ablation for AVNRT is the current treatment of choice in symptomatic patients. It reduces arrhythmia-related hospitalisations and costs, and substantially improves quality of life. [5][6][7][8][9][10][11][12][13][14][15][16] Catheter ablation approaches aimed at the fast pathway have been abandoned; slow pathway ablation, using a combined anatomical and mapping approach, is now the method of choice. This approach offers a success rate of 95 %, has a recurrence rate of approximately 1.3-4.0 %, and has been associated with a low risk of atrioventricular (AV) block that in most, but not all, studies is <1 %. 9,10,15,17 How true are these assumptions, however, in the current era of catheter ablation? Recent reports have provided useful insights into the technique and complications associated with catheter ablation,and several myths have been refuted, outlined below. 5,[18][19][20] We know now that the inferior nodal extensions represent the anatomical substrate of the slow pathway in all forms of AVNRT. 4,[21][22][23] The only legitimate question that still remains unanswered is the relative importance of the right and left extensions. Connexin staining and genotyping studies have identified the left inferior extension and the AV node itself as areas of low connexin 43 (Cx43) expression, and consequently slow conduction, thus suggesting that this is the main substrate of the slow pathway (Figure 1). 24 The inferior nodal extensions at the inferior (posterior) part of the triangle of Koch and below the coronary sinus ostium, as depicted in the right anterior oblique projection, are the appropriate targets for KeywordsAtrioventricular nodal re-entrant tachycardia, catheter ablation Disclosure: The author has no conflicts of interest to declare.A. Proposed circuits of AVNRT based on the role of the inferior nodal extensions. During typical AVNRT (slow-fast) right-or left-sided circuits may occur with antegrade conduction through the inferior inputs and retrograde conduction through the superior inputs or the anisotropic atrionodal transitional area. In atypical AVNRT, conduction occurs anterogradely through the left or right inferior inputs, and retrogradely through the other. Depending on the orientation of the circuit, we may record the so-called fast-slow, slow-slow, or indeterminate types. B. Hypothetical circuits of AVNRT based on connexin genotyping data. Areas in blue have a high expression of Cx43 and therefore display characteristics of fast conduction. These are the right inferior extension, and the lower nodal bundle. There is also a smooth transition in Cx43 at the interface of the transitional cells and the node. Areas in yellow, such as the compact node and the left inferior extension, have very low Cx43 expression and are capable of slow...
