AIMS: The ESC-EHRA Atrial Fibrillation Ablation Long-Term registry is a prospective, multinational study that aims at providing an accurate picture of contemporary real-world ablation for atrial fibrillation (AFib) and its outcome. METHODS AND RESULTS: A total of 104 centres in 27 European countries participated and were asked to enrol 20-50 consecutive patients scheduled for first and re-do AFib ablation. Pre-procedural, procedural and 1-year follow-up data were captured on a web-based electronic case record form...

Objective To evaluate the outcomes of patients with concomitant Brugada syndrome and coronary artery vasospasm. Methods Patients diagnosed with Brugada syndrome with an implantable cardiac defibrillator were retrospectively investigated, and the coexistence of vasospasm was evaluated. The clinical features and outcomes were evaluated, especially in patients with coexistent vasospasm. A provocation test using acetylcholine was performed in patients confirmed to have no organic stenosis on percutaneous coronary angiography to confirm the presence of vasospasm...

AIMS: The early repolarization (ER) pattern has been linked to an increased risk for arrhythmic death in various clinical settings. There are limited and conflicting data regarding the prognostic significance of ER pattern in Brugada syndrome (BS). The aim of this meta-analysis was to provide a detailed analysis of the currently available studies regarding the arrhythmic risk in patients with BS and ER pattern. METHODS AND RESULTS: Current databases were searched until May 2015...

AIM: Peri-procedural thromboembolic (TE) and hemorrhagic events are complications of major concern for patients undergoing cryoballoon (CB) ablation for atrial fibrillation (AF). While peri-procedural anticoagulation management could decrease the incidence of these complications, data on CB ablation are scarce. The role of novel oral anticoagulants (NOACs) has not been thoroughly tested in this population. METHODS: In the present study, we sought to assess acute peri-procedural complications in patients undergoing CB ablation for AF under different anticoagulation regimens; anticoagulation administration was performed according to the CHA2DS2-VASc score guidelines...

Atrial tachyarrhythmias (ATAs) occur in a significant proportion of Brugada syndrome (BrS) patients and are often an important cause of inappropriate shocks. The aim of this retrospective study was to evaluate the incidence of ATAs and ATA-induced inappropriate shocks in early repolarization syndrome (ERS) patients as compared to BrS patients.We analyzed data from 20 consecutive patients who were diagnosed with ERS and compared them with patients diagnosed with BrS (n = 31). Clinical and ICD interrogation data were collected and analyzed for all events with ICD shocks...

BACKGROUND: Brugada-type ECG (Br-ECG) is occasionally observed during acute myocardial ischemia of the right ventricular outflow tract (RVOT). No studies have explored, however, the association of ventricular tachyarrhythmia and development of Br-ECG due to acute ischemia of the RVOT.Methods and Results:The study included 13 consecutive patients with acute ischemia of the RVOT during coronary catheterization. Patients were divided into 2 groups: those with Br-ECG (group B) and those without (group N)...

It is almost a quarter of century that a pioneering work of 2 researchers named Brugada brought the entire scientific community to understanding the molecular, clinical, and electrophysiological aspects of a distinctive syndrome. It affects mainly young adults with syncope and/or sudden cardiac death caused by polymorphic ventricular tachycardia or ventricular fibrillation in the absence of any sign of cardiac degeneration or alteration. Although the involvement of the epicardial layer of the right ventricular outflow tract, and the requirement of pharmacologic challenge for unveiling concealed forms, have been fully characterized, many areas of uncertainties remain to be elucidated, such as the unpredictable usefulness of programmed ventricular stimulation, the role of radiofrequency catheter ablation for reducing ST-segment elevation, and the value of risk stratification in patients diagnosed with upper displacement of right precordial leads...

REVIEW
Sarah H Vermij, Hugues Abriel, Toon A B van Veen
This review presents an extensively integrated model of the cardiac intercalated disc (ID), a highly orchestrated structure that connects adjacent cardiomyocytes. Classically, three main structures are distinguished: gap junctions (GJs) metabolically and electrically connect cytoplasm of adjacent cardiomyocytes; adherens junctions (AJs) connect the actin cytoskeleton of adjacent cells; and desmosomes function as cell anchors and connect intermediate filaments. Furthermore, ion channels reside in the ID. Mutations in ID proteins have been associated with cardiac arrhythmias such as Brugada syndrome and arrhythmogenic cardiomyopathy...

BACKGROUND: Fever is associated with the manifestation of Brugada phenotype and ventricular tachycardia/fibrillation (VT/VF) in patients with Brugada syndrome (BrS). The thermal effect on the pathogenesis of functional substrates in BrS remains unknown. OBJECTIVE: The study aimed to elucidate the thermal effect on BrS phenotype, VT/VF, and electrophysiological characteristics of epicardial functional substrates in BrS. METHODS: We consecutively studied 15 patients with BrS receiving radiofrequency catheter ablation (RFCA) for drug-refractory ventricular tachyarrhythmias...

The connection between fever and sudden death due to ventricular tachycardia has been usually reported in Brugada Syndrome. However the thermosensitive effects caused by fever have been recently described as a possible cause of sudden death in congenital long QT type II syndrome and in idiopathic ventricular fibrillation syndrome. We present a case where fever unmasked a congenital long QT type II syndrome.

Sudden unexplained nocturnal death syndrome (SUNDS) is a perplexing disorder to both forensic pathologists and clinic physicians. Clinical features of SUNDS survivors suggested that SUNDS is similar to Brugada syndrome (BrS). Leucine-rich repeat containing 10 (LRRC10) gene was a newly identified gene linked to dilated cardiomyopathy, a disease associated with sudden cardiac death. To investigate the prevalence and spectrum of genetic variants of LRRC10 gene in SUNDS and BrS, the coding regions of LRRC10 were genetically screened in 113 sporadic SUNDS victims (from January 2005 to December 2015, 30...

AIMS: To study the learning curve with the second-generation cryoballoon technology focusing on safety, efficacy and procedural characteristics. METHODS: We included 300 patients (men 64.6%, mean age 58.3 ± 12.4 years), 240 of whom were treated by four operators without prior experience in atrial fibrillation ablation and compared them with 60 consecutive patients treated by senior operator. To study the learning curves, we divided the study period into two trimesters and analyzed procedure duration, fluoroscopy times, complications, characteristics of the freeze-thaw cycles and midterm outcomes...

BACKGROUND: The role of J-waves in the pathogenesis of ventricular fibrillation (VF) occurring in structurally normal hearts is important. METHODS: We evaluated 127 patients who received an implantable cardioverter-defibrillator (ICD) for Brugada syndrome (BS, n = 53), early repolarization syndrome (ERS, n = 24), and patients with unknown or deferred diagnosis (n = 50). ECG, clinical characteristics, and ICD data were analyzed. RESULTS: J-waves were found in 27/50 patients with VF of unknown/deferred diagnosis...

BACKGROUND: Sport is very important for health promotion and conservation. Active lifestyle and regular exercise reduce cardiovascular disease incidence. The Italian Ministry of Health issued the Law Decree no. 243 (10/18/2014) concerning "guidelines for certification about non-competitive sports" to promote safety in sports. This regulation defines the activities for which a certificate is required, the professional actors involved and the clinical exams to be performed according to the patient's health status...

Catecholaminergic polymorphic ventricular tachycardia is a rare familial arrhythmogenic disease. It usually occurs in juvenile patients with a structurally normal heart and causes exercise-emotion triggered syncope and sudden cardiac death. The main gene associated with catecholaminergic polymorphic ventricular tachycardia is RyR2, encoding the cardiac ryanodine receptor protein which is involved in calcium homeostasis. After the identification of a 16 year-old man presenting with exercise-induced sudden cardiac death, clinically diagnosed as catecholaminergic polymorphic ventricular tachycardia, we collected the family information and performed a comprehensive genetic analysis using Next Generation Sequencing technology...
