Randomized Controlled Trial Multicenter Study Comparative Study
Safety and efficacy of multipolar pulmonary vein ablation catheter vs. irrigated radiofrequency ablation for paroxysmal atrial fibrillation: a randomized multicentre trial.
The current challenge in atrial fibrillation (AF) treatment is to develop effective, efficient, and safe ablation strategies. This randomized controlled trial assesses the medium-term efficacy of duty-cycled radiofrequency ablation via the circular pulmonary vein ablation catheter (PVAC) vs. conventional electro-anatomically guided wide-area circumferential ablation (WACA). ⋯ NCT00678340.

Multicenter Study Comparative Study
Correlation of intracardiac electrogram with surface electrocardiogram in Brugada syndrome patients.
The objective of this study was to correlate the electrocardiogram (ECG) modification during an Ajmaline challenge in patients affected by the Brugada syndrome and implanted with an implantable cardioverter-defibrillator (ICD) with the morphological changes of their ICD's intracardiac electrogram (IEGM). ⋯ In Brugada patients, ajmaline challenge elicits significant T wave amplitude changes within the ICD IEGM, greater than those of the IEGM ST segment. This study is the first step to provide new tools able to continuously monitor the type I Brugada aspect in patients affected by the Brugada syndrome.

Multicenter Study
Long-term follow-up of asymptomatic Brugada patients with inducible ventricular fibrillation under hydroquinidine.
To evaluate the long-term efficacy and safety of an electrophysiologically guided therapy, based on a strategy of treatment using hydroquinidine (HQ) among asymptomatic Brugada patients with inducible ventricular fibrillation (VF). ⋯ Our long-term follow-up results emphasize that the rate of arrhythmic events among asymptomatic Brugada patients with inducible VF remains low over time. Our results also suggest that residual inducibility under HQ is of limited value to predict events during follow-up.

Multicenter Study Clinical Trial
A prospective survey in European Society of Cardiology member countries of atrial fibrillation management: baseline results of EURObservational Research Programme Atrial Fibrillation (EORP-AF) Pilot General Registry.
Given the advances in atrial fibrillation (AF) management and the availability of new European Society of Cardiology (ESC) guidelines, there is a need for the systematic collection of contemporary data regarding the management and treatment of AF in ESC member countries. ⋯ The EURObservational Research Programme Atrial Fibrillation (EORP-AF) Pilot Registry has provided systematic collection of contemporary data regarding the management and treatment of AF by cardiologists in ESC member countries. Oral anticoagulant use has increased, but novel OAC use was still low. Compliance with the treatment guidelines for patients with the lowest and higher stroke risk scores remains suboptimal.

Multicenter Study
Current periprocedural management of ablation for atrial fibrillation in Europe: results of the European Heart Rhythm Association survey.
The purpose of this EP Wire survey was to assess clinical practice in periprocedural management of atrial fibrillation ablation. This survey is based on an electronic questionnaire sent to the European Heart Rhythm Association Research Network members. ⋯ The results of the survey have shown that periprocedural management is generally in accordance with guidelines and consensus recommendations on ablation for atrial fibrillation ablation, although there are some areas of variation. Differences between high- and low-volume centres are observed with respect to patient selection, antiarrhythmic drug management, and heparin bridging.
