AF is the most common sustained cardiac arrhythmia in clinical practice. It is associated with increased risk of stroke and heart failure (HF), and is a significant global health challenge.1 Catheter ablation procedures, which isolate the pulmonary veins (PV) from the left atrium and prevent AF initiation, are effective and safe treatment options, and have emerged as the preferred rhythm control… View more

Impact of Micro-, Mini- and Multi-Electrode Mapping on Ventricular Substrate Characterisation
Author(s): Benjamin Berte , Katja Zeppenfeld , Roderick Tung Added: 3 years ago
Accurate substrate characterisation is important for depicting scar-related re-entrant tachycardia to optimise ablation targets and strategies. The underlying substrate can be analysed using electrogram (EGM) characteristics, such as low voltage, local abnormal voltage activity (LAVA), evoked potentials or late potentials, conduction analysis in sinus rhythm or differential pacing, or using… View more

Electrophysiology & Arrhythmia
Author(s): Saagar Mahida , Benjamin Berte , Seigo Yamashita , et al Added: 3 years ago
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… View more

Personal History Dr Natale is an American cardiologist and electrophysiologist known for his work in atrial fibrillation ablation. He was born in Syracuse, Italy and has been practising medicine in the United States and Italy for over 35 years.2 His father, a physician, was a strong influence in his decision to choose cardiology.3 He is known as the first electrophysiologist in the US to… View more
A New Era in Zero X-ray Ablation
Author(s): Giuseppe Mascia , Marzia Giaccardi Added: 3 years ago
X-rays used in interventional cardiology are proven (class I) carcinogens, and the electrophysiology community should make every effort to give “the right imaging exam, with the right dose, to the right patient”.1 This may be an effective strategy for the primary prevention of cancer for physicians, medical staff and patients (particularly children, young adults and women).2 The impact of X-rays… View more

Author(s): Irina Suman-Horduna , Sonya Babu-Narayan , Sabine Ernst Added: 3 years ago
Catheter ablation has moved from ablation of ‘simple’ substrates like accessory pathways,1 atrioventricular nodal re-entrant tachycardias (AVNRTs)2 and re-entrant or focal tachycardia (of either ventricular or atrial origin)3–5 in recent years to more complex arrhythmias such as atrial or ventricular tachycardia (VT) or fibrillation.6–8 Even patients with complex congenital heart disease that may… View more

Electrophysiology & Arrhythmia
Author(s): David Filgueiras-Rama , Jose L Merino Added: 3 years ago
Atrial fibrillation (AF) is the most common sustained arrhythmia in the clinical practice.1 The prevalence of the arrhythmia is progressively increasing in developed countries and moreover, it is expected to affect up to 12 million people only in the US by 2050.2 Antiarrhythmic drugs continue to represent the first-line of treatment in AF patients, either to restore sinus rhythm or to prevent… View more
