Atrial Tachycardias After Atrial Fibrillation Ablation: How to Manage?
Author(s): Yuan Hung , Shih-Lin Chang , Wei-Shiang Lin , et al Added: 3 years ago
AF is the most common clinical arrhythmia that causes severe adverse cardiovascular events, such as ischaemic stroke and acute heart failure.1 Triggers from the pulmonary vein (PV) have been identified as crucial ectopic sources that initiate AF and pulmonary vein isolation (PVI) is the cornerstone for catheter ablation of AF.2,3 Per the European and US AF guidelines, catheter ablation of AF is… View more

Advanced catheter-based technologies employed for the ablation of symptomatic atrial fibrillation (AF) have revolutionised the management of this common sustained arrhythmia. In the late 1990s, premature depolarisations originating from the myocardial sleeves within the pulmonary veins were recognised to initiate AF. This landmark discovery rendered pulmonary vein isolation (PVI) as the… View more

Maintenance of sinus rhythm in patients with non-paroxysmal AF is often challenging and complex. Catheter ablation is usually superior to anti-arrhythmic drug therapy alone. However, recurrence rates are high and have remained suboptimal. Although pulmonary vein isolation (PVI) is usually effective in treating paroxysmal AF, it is not sufficient for many patients with non-paroxysmal AF,… View more

Pioneering electrophysiology studies in the 1990s defined the anatomical boundaries of typical atrial flutter, identified regions for effective catheter ablation of this arrhythmia and described procedural endpoints to minimise recurrences after ablation. Activation and entrainment mapping demonstrated that typical flutter arises from reentry around the tricuspid annulus.1 Criteria to confirm… View more

The Convergent AF Ablation Procedure: Evolution of a Multidisciplinary Approach to AF Management
Author(s): Karan Wats , Andy Kiser , Kevin Makati , et al Added: 3 years ago
AF is the most commonly encountered atrial arrhythmia in clinical practice. Restoration of normal sinus rhythm through catheter- and surgically based approaches has been increasingly used as technologies and outcomes have improved.1 Success rates for AF ablation vary greatly depending on the duration of AF (more successful for paroxysmal AF, less successful in persistent AF and even less so for… View more

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia observed in clinical practice, occurring in approximately 2 % of the general population.1–3 A progressive increase in both the prevalence and incidence of AF has been demonstrated in recent years, defining AF as a major economic and public health issue.1 The identification of sites of AF initiation and/or maintenance within… View more
