In the setting of persistent atrial fibrillation (AF), the current ablation strategy combines pulmonary vein (PV) isolation and substrate modulation. Substrate modulation can be performed either by linear lesion deployment or by complex fractionated atrial electrogram (CFE) elimination. These two substrate modulation methods can be either exclusive or complementary. However, although the…

2D echocardiography (2DE) is a common diagnostic and treatment planning tool in clinical cardiology, especially for the assessment of left ventricular (LV) volume and function. However, traditional 2DE is severely limited by its dependence on geometrical assumptions, which can lead to inaccuracies in volume quantification.1 Because 3D echocardiographic (3DE) imaging eliminates geometrical…

Atrial fibrillation (AF) is a supraventricular arrhythmia associated with an increased risk of stroke, heart failure and all-cause mortality.1 Sinus rhythm control and heart rate control are two commonly used strategies to manage patients with AF, alongside the use of anticoagulants for prevention of stroke. Rhythm control with antiarrhythmic drugs (AADs) has similar survival benefits to rate…

Advances in the treatment of complex congenital heart disease over the past 20 years have led to a dramatic improvement in long-term survival.1 However, the incidence of cardiac arrhythmias as a sequel of palliative heart surgery has also increased significantly in adolescent and adult survivors of congenital heart disease surgery.1,2 Cardiac arrhythmias are the leading cause of emergency…

The availability of remote navigation by mean of two permanent magnets - the positions of which are computer controlled - has started a new era in cardiac electrophysiology and radiofrequency catheter ablation.1 When located close to the thorax in navigate position, both magnets create a relatively uniform magnetic field (0.08-T) of approximately 15cm inside the chest of the patient. The distal…

Catheter ablation has become the curative treatment for various cardiac arrhythmias. Extending the indications from simple supraventricular tachycardias to complex arrhythmias such as ventricular tachycardia or atrial fibrillation (AF) has led to more challenging procedures. These procedures have prolonged fluoroscopy exposure and the need for stable and reproducible catheter movement. Therefore,…

Atrial fibrillation (AF) is the most common form of cardiac arrhythmia and is associated with high rates of morbidity and mortality.1 AF can be paroxysmal or persistent, and remains asymptomatic in some cases. However, in more severe and persistent cases AF may cause congestive heart failure, palpitations, syncope, and chest pains. Additionally, patients with AF have a significantly higher risk…

Since the initial description that in the majority of patients paroxysmal atrial fibrillation (AF) is triggered by pulmonary vein (PV) ectopy,1 catheter ablation of AF has gone from a niche procedure to a common one, with approximately 20,000 ablations performed per year in the US alone. However, AF ablation remains a technically difficult procedure, requires long training to become proficient,2…

In developed countries, the number of atrial fibrillation (AF) catheter ablation procedures increases every year. Continuous scientific and technological innovation in the area of AF ablation has broadened the spectrum of therapeutic options for patients with AF, and it is likely to be a contributing factor in making AF ablation a practice no longer restricted to a few operators with greater…
