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: The current anatomical ablation approach for AFL and criteria for evaluation of the IVC-TA isthmus block is associated with an acute success rate of 90% and a long-term recurrence rate of 10%.

TL;DR: In this paper, a mixed methods approach was developed to determine the impact of building physics and user behaviour on heating energy consumption separately, and it was argued that future policy measures should focus on user-technology interface design rather than solely focusing on ever stricter efficiency standards.
Abstract: The European Union seeks to reduce CO 2 emissions in the residential sector by introducing ever stricter energy efficiency standards for newly constructed projects and energy-oriented modernisations. Despite these regulatory efforts, the actual energy consumption significantly deviates from these ambitious goals. Based on this observation it will be argued that it is possible to explain this deviation by putting the focus on users’ practices rather than solely focusing on building physics. In order to determine the impact of building physics and user behaviour on heating energy consumption separately, a mixed methods approach was developed. Actual heat energy consumption data of flats in two German refurbishment areas was collected and semi-standardized interviews with the inhabitants of 80 of these households were conducted. We use qualitative data to identify households’ practices related to energy consumption and measure the relative impact of these practices with quantitative data. Aside from the building physics, we can observe that preferences for thermal comfort as well as ventilation practices have the strongest influence on households’ heating energy consumption after retrofitting. Based on these findings, it is argued that future policy measures should focus on user-technology interface design rather than solely focusing on ever stricter efficiency standards.

TL;DR: The current report underlines the importance of a patient-tailored ablation approach and suggests that cryothermic balloon technology may be more applicable in delicate cardiac structures by developing new anatomically adapted balloon shapes and sizes.
Abstract: Trigger sources of paroxysmal atrial fibrillation (PAF) are not limited to a pulmonary vein origin and may be achievable by cardiac vascular structures like the coronary sinus (CS), the vena cava superior and in some rare cases by a persistent left superior vena cava (LSVC). Cryoballoon ablation has been shown to be effective in pulmonary vein isolation. We report an unusual case of using this technique in the dilated CS in case of a persistent LSVC. A 64 year old patient presented PAF recurrences after cryo pulmonary vein isolation 4 months before. A maintaining pulmonary vein isolation could be demonstrated by transseptal mapping. Further bi-atrial mapping localized repetitive atrial trigger activity in a dilated CS proceeding to a LSVC. A cryoballoon was deployed in the CS target area and during cryoablation the triggered activity suspended. Ablation side effects were excluded by coronary angiography. During a follow up time of 8 months the patient has remained free of PAF recurrences. The current report underlines the importance of a patient-tailored ablation approach. Cryothermic balloon technology may be more applicable in delicate cardiac structures by developing new anatomically adapted balloon shapes and sizes.

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 …
