TL;DR: Pulmonary vein isolation with a new cryoballoon technique is feasible and sinus rhythm can be maintained in the majority of patients with PAF by circumferential PVI using a cryoablation system.

TL;DR: Remote magnetic navigation for PVAI seems to be safe and feasible using an irrigated gold-tip catheter and there was a trend to a better outcome in patients without previous attempts of AF ablation.
Abstract: Magnetically guided irrigated ablation has been introduced for atrial fibrillation (AF) ablation. However, data on ablation of persistent AF is scarce, and first-generation platinum–iridium catheters were burdened by char formation at the catheter tip. Furthermore, energy transmission of these catheters may be suboptimal. Irrigated gold-tip catheters have been introduced to overcome these problems. Antral pulmonary vein (PV) isolation (PVAI) was performed using a 5-mm irrigated gold-tip magnetic catheter (power setting, 48 °C maximum, 50 W, 15 s lesion duration; flow-rate, 30 mL/min). The catheter tip was guided by a uniform magnetic field and a motor drive. Left atrial maps were created using an impedance-based left atrial reconstruction and fused with a preprocedural CT or an intraprocedural rotational angiography-based scan. Fifty-seven patients (42 male, 61.9 ± 8.8 years) underwent PVAI for symptomatic, drug-refractory persistent AF. PVAI was performed successfully in all patients confirmed by entrance block. Procedure time (skin-to-skin) was 214 ± 47 min (104–354 min). Fluoroscopy time was 31 ± 21 min. Ablation time was 4,153 ± 1,350 s. No char or thrombus formation was found at the catheter tip. One pericardial tamponade was observed. Freedom from atrial tachyarrhythmias could be achieved in 57.9 % of the patients included in a follow-up of 11.6 ± 4.2 month. There was a trend to a better outcome in patients without previous attempts of AF ablation (n = 48; 60.4 % vs. 44.4 %, p = 0.47). Remote magnetic navigation for PVAI seems to be safe and feasible using an irrigated gold-tip catheter. Effectiveness of this novel technique can be confirmed by mid-term outcome.

TL;DR: This prospective study aimed to evaluate very long‐term outcome after CB‐PVI for AF.
Abstract: Cryoballoon‐guided pulmonary vein isolation (CB‐PVI) for symptomatic atrial fibrillation (AF) has become an established treatment option with encouraging results in terms of safety and efficacy. Data reporting on long‐term data beyond a follow‐up (FU) period of 5 years is scarce. This prospective study aimed to evaluate very long‐term outcome after CB‐PVI for AF.

TL;DR: This 2012 Consensus Statement is to provide a state-of-the-art review of the field of catheter and surgical ablation of AF and to report the findings of a Task Force, convened by the Heart Rhythm Society, the European Heart Rhythm Association, and the European Cardiac Arrhythmia Society and charged with defining the indications, techniques, and outcomes of this procedure.
Abstract: During the past decade, catheter ablation of atrial fibrillation (AF) has evolved rapidly from an investigational procedure to its current status as a commonly performed ablation procedure in many major hospitals throughout the world. Surgical ablation of AF, using either standard or minimally invasive techniques, is also performed in many major hospitals throughout the world.
In 2007, an initial Consensus Statement on Catheter and Surgical AF Ablation was developed as a joint effort of the Heart Rhythm Society, the European Heart Rhythm Association, and the European Cardiac Arrhythmia Society.1 The 2007 document was also developed in collaboration with the Society of Thoracic Surgeons and the American College of Cardiology. Since the publication of the 2007 document, there has been much learned about AF ablation, and the indications for these procedures have changed. Therefore the purpose of this 2012 Consensus Statement is to provide a state-of-the-art review of the field of catheter and surgical ablation of AF and to report the findings of a Task Force, convened by the Heart Rhythm Society, the European Heart Rhythm Association, and the European Cardiac Arrhythmia Society and charged with defining the indications, techniques, and outcomes of this procedure. Included within this document are recommendations pertinent to the design of clinical trials in the field of AF ablation, including definitions relevant to this topic.
This statement summarizes the opinion of the Task Force members based on an extensive literature review as well as their own experience. It is directed to all health care professionals who are involved in the care of patients with AF, particularly those who are undergoing, or are being considered for, catheter or surgical ablation procedures for AF. This statement is not intended to recommend or promote catheter ablation of AF. Rather the ultimate judgment regarding care of a particular patient …

TL;DR: The STOP AF trial demonstrated that cryoballoon ablation is a safe and effective alternative to antiarrhythmic medication for the treatment of patients with symptomatic paroxysmal AF, for whom at least one antiarrHythmic drug has failed, with risks within accepted standards for ablation therapy.
