Aims: The transseptal approach is used for left atrial access during the ablation of atrial fibrillation (AF) and other left-sided arrhythmia substrates. Transseptal puncture (TP) is commonly performed with fluoroscopic guidance, contrast injection, and pressure monitoring. In many centres, additional techniques [intracardiac echocardiography (ICE), transoesophageal echocardiography (TEE), radiofrequency needle] are used to facilitate TP but its use adds costs. In this retrospective study, we studied the safety and complication rate when TP was routinely done with fluoroscopic guidance, contrast injection, and pressure monitoring using ICE or TEE only in selected cases...

Aims: The aim of the study is to define long-term outcome of pulmonary vein isolation (PVI) in atrial fibrillation (AF) and to determine whether time window between AF diagnosis and PVI affects outcome. Methods and results: Consecutive AF patients undergoing PVI (2006-14) were followed for 5 years. Primary outcome was clinical success, defined as freedom of documented AF without anti-arrhythmic drugs respecting a 1-month blanking period. A 1000 patients were included (age 60 ± 10 years, CHA2DS2-VASc score 1 ± 1)...

Aims: In this study, we sought to evaluate the safety and efficacy of cryoballoon (CB) based empirical left atrial appendage (LAA) isolation as an adjunct to pulmonary vein isolation (PVI) compared to the PVI-only strategy in patients with persistent AF. Objectives: Clinical outcomes of catheter ablation were less beneficial for persistent atrial fibrillation (AF) than paroxysmal AF. Methods and results: A total of 100 consecutive patients with persistent AF underwent both PVI and additional LAA isolation using CB (Group II)...

Aims: The therapeutical management of atrial fibrillation (AF) in the setting of Brugada syndrome (BS) might be challenging as many antiarrhythmic drugs (AADs) with sodium channel blocking properties might lead to to the development of ventricular arrhythmias. This study sought to evaluate the clinical outcome in a consecutive series of patients with BS having undergone pulmonary vein (PV) isolation by means of radiofrequency (RF) or cryoballoon (CB) ablation and the efficacy of catheter ablation for preventing inappropriate interventions delivered by implantable cardioverter defibrillators (ICD) on a 3-year follow up...

Aims: Atrial arrhythmias are common in patients with Ebstein's anomaly (EA) despite cardiac surgical repair and concomitant Maze procedures. We aimed to evaluate the outcome of radiofrequency catheter ablation in this group of patients. Methods and results: All patients with EA and atrial arrhythmias who underwent catheter ablation for atrial arrhythmias between 1/1999 and 1/2016 were included. Atrial arrhythmia recurrence was identified as the primary outcome; secondary outcomes included repeat ablation, need for antiarrhythmic medications after ablation, and death...

Aims: Atrial fibrillation (AF) transcatheter ablation is a safe and effective procedure. However, outcome over 10 years of follow-up has never been reported. The aim of this study is to assess outcome, describe predictors of recurrences, and report on quality of life (QoL) the decade after an AF ablation. Methods and results: Patients referred for AF ablation in a single high volume centre from June 2004 to June 2006 were enrolled and followed in a prospective fashion by yearly clinical assessment and Holter monitoring...

Aims: Measurement of circulating biomarkers of fibrosis may have a role in selecting patients and treatment strategy for catheter ablation. Pro-collagen type III N-terminal pro-peptide (PIIINP), C-telopeptide of type I collagen (ICTP), fibroblast growth factor 23 (FGF-23), and galectin 3 (gal-3) have all been suggested as possible biomarkers for this indication, but studies assessing whether peripheral levels reflect intra-cardiac levels are scarce. Methods and results: We studied 93 patients undergoing ablation for paroxysmal atrial fibrillation (AF) (n = 63) or non-paroxysmal AF (n = 30)...

Aims: Atrial tachycardia (AT) related to atrial fibrillation (AF) ablation frequently poses a diagnostic challenge. Downstream overdrive pacing (DOP) can be used to rapidly detect reentry and assess proximity of a pacing site to an AT circuit or focus. We hypothesized that systematic DOP using multielectrode catheters would facilitate AT mapping. Methods and results: DOP identified constant fusion when the post-pacing interval (PPI)-tachycardia cycle length (TCL) <40 ms and stimulus to adjacent upstream atrial electrogram interval >75% of TCL...

Aims: Initiating mechanisms of atrial fibrillation (AF) remain poorly understood, involving complex interaction between triggers and the atrial substrate. This study sought to classify the transitional phenomena, hypothesizing that there is consistency within and between patients in trigger-substrate interaction during transition to AF. Methods and results: Non-contact left atrial (LA) mapping was performed in 17 patients undergoing ablation for paroxysmal AF. All had spontaneous ectopy...

Aims: Focal Impulse and Rotor Modulation (FIRM) uses 64-electrode basket catheters to identify atrial fibrillation (AF)-sustaining sites for ablation, with promising results in many studies. Accordingly, new basket designs are being tested by several groups. We set out to determine the procedural safety of adding basket mapping and map-guided ablation to conventional pulmonary vein isolation (PVI). Methods and results: We collected 30 day procedural safety data in five US centres for consecutive patients undergoing FIRM plus PVI (FIRM-PVI) compared with contemporaneous controls undergoing PVI without FIRM...

Aims: Atrial fibrillation (AF) is associated with changes in left atrial (LA) volume, but the relationship between LA size, AF burden, and electrical conduction behaviour is still uncertain. The aim of this study was to quantify the association and impact of these parameters on the single-procedure outcome after circumferential antral ablation for pulmonary vein isolation. Methods and results: Left atrial assessment was performed in 129 consecutive patients using pre-procedural imaging in three dimensions (sphericity, indexed volume), two dimensions (diameters), and from echocardiography in one dimension (long axis)...

OBJECTIVES: We sought to investigate the incidence of atrial fibrillation after catheter ablation for typical atrial flutter and to determine the predictors for symptomatic atrial fibrillation that required a further additional dedicated ablation procedure. DESIGN: 127 patients underwent elective cavotricuspid isthmus ablation with the indication of symptomatic, typical atrial flutter. The occurrence of atrial flutter, atrial fibrillation, cerebrovascular events and the need for additional ablation procedures for symptomatic atrial fibrillation was assessed during long-term follow-up...

OBJECTIVES: Concomitant surgical ablation of atrial fibrillation (AF) is recommended for patients undergoing off-pump coronary revascularization in the presence of this arrhythmia. Achievement of optimal visualization of pulmonary veins while maintaining stable haemodynamic conditions is crucial for proper completion of the ablation procedure. This study evaluates the safety and feasibility of right atrial positioning using a suction-based cardiac positioner as opposed to compressive manoeuvres for exposure during off-pump surgical ablation for AF...

OBJECTIVES: Atrial fibrillation (AF) is common in patients with hypertrophic cardiomyopathy (HCM) and it is often poorly tolerated because of loss of atrial contraction and reduced filling time with rapid ventricular rates. Restoring sinus rhythm is of great clinical benefit to HCM patients. Very few data exist regarding surgical ablation of concomitant AF in this setting. The aim of this study was to evaluate the mid-term outcome of surgical AF ablation in patients who underwent cardiac surgery due to HCM...
