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

Cardiac MRI to Manage Atrial Fibrillation
Author(s): Yan Zhao , Lilas Dagher , Chao Huang , et al Added: 3 years ago
AF is a common arrhythmia in clinical practice, with a prevalence of 2.7–6.1 million that is expected to rise to 5.6–12 million by 2050 in the US alone.1,2 Patients with AF have an increased risk of stroke and mortality and a decreased quality of life.3 In addition, management of AF increases the cost of healthcare.4,5,6 The mechanisms of AF are complex and are associated with electric and… View more

Atrial fibrillation (AF) is a remarkably common arrhythmia, affecting roughly 6 % of patients over 65 years of age, with an estimated US prevalence of over two million patients.1 That prevalence is likely to increase as patients live longer, and will contribute to rising morbidity and mortality over time.2-4 Efforts to treat AF remain imperfect. Rhythm control approaches typically consist either… View more

Atrial Myopathy Underlying Atrial Fibrillation
Author(s): Harold Rivner , Raul D Mitrani , Jeffrey J Goldberger Added: 3 years ago
AF is the most common sustained cardiac rhythm disturbance.1 Worldwide, there is an estimated 33.5 million people with AF as of 2010.2 While there are multiple estimates, the yearly incidence in the US is expected to grow, for example, from 1.2 million cases in 2010 to 2.6 million cases in 2030 and upwards of 6–12 million cases by 2050.1,3 It is associated with increased morbidity and mortality4… View more

Percutaneous catheter treatment for atrial fibrillation (AF) has seen an exponential uptake since the first cases were published exactly two decades ago.1 Evolving over different approaches and treatment strategies, current standard of care consists of pulmonary vein isolation (PVI) through radiofrequency (RF) or other energy sources. While this treatment has been shown to be superior to… View more

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… 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
