The number of catheter ablations for atrial fibrillation (AF) treatment has gradually increased over the last 15 years since the first report on the importance of pulmonary vein (PV) foci for triggering AF.1 Catheter ablation for AF is a complex procedure with multiple steps, such as transseptal puncture, mapping of the left atrium and PVs and extensive linear ablation around PV ostia. Not… View more

Defining Left Bundle Branch Block Patterns in Cardiac Resynchronisation Therapy: A Return to His Bundle Recordings
Author(s): Roderick Tung , Gaurav A Upadhyay Added: 3 years ago
In 1970, Durrer et al. recorded the total excitation of the human heart with 870 electrodes and confirmed the first 10 ms of left ventricular (LV) activation as trifascicular in nature.1 The rapid and synchronous activation of the LV through the specialised His–Purkinje network is highly intricate and efficient, preserving normal physiological coupling between electrical excitation and mechanical… View more

Atrial Fibrillation Structural Substrates: Aetiology, Identification and Implications
Author(s): Ahmed M Al-Kaisey , Ramanathan Parameswaran , Jonathan M Kalman Added: 3 years ago
AF is the most common sustained cardiac rhythm disorder and is associated with increased morbidity and mortality. Since the first description of AF initiation by triggers from pulmonary veins sleeves, pulmonary vein isolation (PVI) has become the standard ablation strategy in patients with AF.1 However, freedom from the arrhythmia, particularly in non-paroxysmal AF, remains suboptimal, and it is… View more

Treatment of atrial fibrillation (AF) classically focuses on eliminating triggers near and from the pulmonary veins, which may initiate AF. However, the 1–2 year success rate of pulmonary vein isolation (PVI) remains 40–50% for persistent AF1,2 and 50–65% for paroxysmal AF,3–5 while supplementary linear lesions or extensive ablation at electrogram-targets have had disappointing results and may… View more

Idiopathic Left Ventricular Tachycardia
Author(s): Hongwu Chen , Kit Chan , Sunny S Po , et al Added: 3 years ago
Ventricular tachycardia (VT) originating from the Purkinje system is the most common type of idiopathic left ventricular tachycardia (ILVT), especially among young Asians.1,2 It usually has a benign course. Research over the past two decades has deepened our understanding of the anatomy of the Purkinje system and the mechanisms of ILVT. This review focuses on the research history and anatomy of… View more

Catheter ablation is more effective than pharmacological therapy for the secondary prevention of patients with paroxysmal1,2 and persistent3,4 atrial fibrillation (AF) and has an emerging role in the primary prevention of paroxysmal AF.5,6 Nevertheless, in randomised clinical trials (RCTs) its success in treating patients with paroxysmal AF is 40–60% for a single procedure and 70% for multiple… View more

Catheter ablation of AF has shown steady growth over the past two decades with a nearly 15 % annual increase in the US.1 This growth can be attributed in large part to four factors: an increase in operators and institutions performing the procedure;2 a steady rise in AF prevalence, which is predicted to reach 12 million in the US by 2030;3 a larger spectrum of AF patients with more complex atrial… View more
