PURPOSE: Acute pericarditis is a minor complication following atrial fibrillation (AF) ablation procedures. The aim of the study was to evaluate the incidence and clinical aspects of pericarditis following cryoballoon (CB) ablation of AF investigating a possible association with procedural characteristics and a possible relationship with post-ablation recurrences. METHODS: Four hundred fifty consecutive patients (male 73%, age 59.9 ± 11.2 years) with drug-resistant paroxysmal AF who underwent CB ablation as index procedure were enrolled...

Renal afferent and efferent sympathetic nerves are involved in the regulation of blood pressure and have a pathophysiological role in hypertension. Additionally, several conditions that frequently coexist with hypertension, such as heart failure, obstructive sleep apnea, atrial fibrillation, renal dysfunction, and metabolic syndrome, demonstrate enhanced sympathetic activity. Renal denervation (RDN) is an approach to reduce renal and whole body sympathetic activation. Experimental models indicate that RDN has the potential to lower blood pressure and prevent cardio-renal remodeling in chronic diseases associated with enhanced sympathetic activation...

Few patients with atrial fibrillation (AF) receive care by cardiac electrophysiologists. Although previous work has highlighted differential care for patients with AF treated by electrophysiologists, it is unclear whether this is associated with improved clinical outcomes. This retrospective population-level propensity score-matched cohort study included patients aged 20 to 80 years with new-onset AF presenting to an emergency department (ED) in Ontario, Canada, between 2010 and 2012. Patients were followed until March 31, 2015...

BACKGROUND Left bundle branch block (LBBB) is associated with atrial fibrillation (AF) and systolic heart failure, which can be treated with cardiac resynchronization therapy (CRT) that includes an implantable cardiac device (ICD). However, in some patients, LBBB may vary with heart rate, and during episodes of AF in LBBB, aberrant ventricular conduction, or wide QRS complex tachycardia (Ashman beats) can occur. This report is a case of LBBB treated with pharmacologic CRT, without the use of an ICD. CASE REPORT A 68-year-old man presented with persistent AF and systolic heart failure...

BACKGROUND: Mortality and morbidity are higher among patients with atrial fibrillation and heart failure than among those with heart failure alone. Catheter ablation for atrial fibrillation has been proposed as a means of improving outcomes among patients with heart failure who are otherwise receiving appropriate treatment. METHODS: We randomly assigned patients with symptomatic paroxysmal or persistent atrial fibrillation who did not have a response to antiarrhythmic drugs, had unacceptable side effects, or were unwilling to take these drugs to undergo either catheter ablation (179 patients) or medical therapy (rate or rhythm control) (184 patients) for atrial fibrillation in addition to guidelines-based therapy for heart failure...

Heart failure patients are predisposed to develop arrhythmias. Supraventricular arrhythmias can exacerbate the heart failure symptoms by decreasing the effective cardiac output and their control require pharmacological, electrical, or catheter-based intervention. In the setting of atrial flutter or atrial fibrillation, anticoagulation becomes paramount to prevent systemic or cerebral embolism. Patients with heart failure are also prone to develop ventricular arrhythmias that can present a challenge to the managing clinician...

Aims: Thoracoscopic surgical ablation has evolved into a successful strategy for symptomatic atrial fibrillation (AF) refractory to other therapy. More widespread referral is limited by the lack of information on potential complications. Our aim was to systematically evaluate 30-day complications of totally thoracoscopic surgical ablation. Methods and results: We retrospectively studied consecutive patients undergoing totally thoracoscopic surgical ablation at a referral centre in the Netherlands (2007-2016)...

BACKGROUND: Atrial fibrillation (AF) ablation is increasingly used in patients with reduced left ventricular ejection fraction (LVEF). The aim of the present study was to evaluate the long-term results of a single radiofrequency catheter ablation procedure in heart failure (HF) patients with AF. HYPOTHESIS: We tested the hypothesis that left atrial ablation is an effective therapeutic modality in patients with heart failure. METHODS: Our study included HF patients with LVEF <50% who underwent catheter ablation for AF at our department between January 2010 and March 2017...

Atrial fibrillation (AF) is the most common cardiac arrhythmia. The incidence of AF increases with age and is associated with increased stroke, heart failure and mortality. Persistent and long standing persistent AF is difficult to treat and often refractory to medical therapy and catheter ablation. Areas covered: This article reviews the historical development of the surgical Cox-MAZE procedure and current hybrid and minimally invasive surgical approaches for the treatment of persistent and long standing persistent AF...

Atrial fibrillation is an epidemic in Asia that is increasingly prevalent. Apart from stroke risk stratification and management of anticoagulation, physicians managing this group of patients also need to determine an optimal strategy in terms of rate or rhythm control. With new techniques of catheter ablation to maintain patients in sinus rhythm, patients with atrial fibrillation now have more options for treatment, on top of pharmacological methods. This paper aims to review the current evidence for rate and rhythm control in both general patients and subgroups of interest commonly encountered in clinical practices such as obesity, heart failure and thyroid disease...

BACKGROUND: The extent of left atrial (LA) baseline low-voltage areas (LVA-B), which may be a surrogate for fibrosis, is associated with recurrent atrial fibrillation (AF) after ablation. This study aimed to assess the relationship between the extent of LVA-B isolated by ablation (LVA-I) and AF recurrence. METHODS: The study cohort included 159 consecutive patients with drug-refractory AF who underwent an initial AF ablation with LA voltage mapping during sinus rhythm...

Introduction: Atrial fibrillation is the most common cardiac arrhythmia in the United States. It has been associated with a reduction in patient quality of life and more serious complications such as stroke and heart failure. The aim of this study was to compare the efficacy of commonly performed invasive procedures in keeping patients in normal sinus rhythm. Methods and Results: A retrospective chart review was performed on all patients who underwent primary radiofrequency catheter ablation, the complete Cox-maze, or the hybrid maze at OSF Saint Anthony Medical Center between January 2010 and December 2013 (n=140)...

Catheter ablation of atrial fibrillation (AF) is a current therapeutic option but its efficacy for the treatment of long-lasting persistent AF (l-lpAF) remains suboptimal. We tested the laser method as an alternative for catheter ablation of l-lpAF by using an open-irrigated electrode laser mapping and ablation (ELMA) catheter. Laser ablation was attempted in 48 patients aged 50-81 years (69 ± 7.6 y, female = 28) with drug resistant (3.5 trials) l-lpAF (≥12 months). All of the patients had comorbidities: congestive heart failure NYHA II-III (100%), hypertension 29 (60%), coronary artery disease 19 (40%), and heart valve defect 17 (35%)...

BACKGROUND: atrial fibrillation(AF) is a frequent manifestation of cardiac involvement in genetic and wild-type transthyretin-related familial amyloidosis(TTR-FA). However, ectasia of coronary arteries and ablation for AF have not been reported in TTR-FA. METHODS AND RESULTS: A 65yo male developed progressive sensori-motor polyneuropathy since age 59y. At age 60y bifascicular block and myocardial thickening were recognised. At age 62y heart failure developed and work-up with cardiac MRI suggested amyloidosis but biopsy was non-informative...

Many trials have shown improvements in left ventricular function, exercise capacity, and quality of life after catheter ablation (CA) of atrial fibrillation (AF) in patients with heart failure (HF). We sought to evaluate the impact of CA on hard outcomes in a retrospective cohort study. AF patients with symptomatic HF from 3 hospitals were included. Our primary endpoint was major adverse cardiac events (MACEs), a composite of all-cause mortality, stroke, and unplanned hospitalization. In total, 90 patients underwent CA and 304 ones received rate control (RaC) were included...

BACKGROUND: Pulmonary vein isolation (PVI) has become a widely accepted therapy in patients suffering from symptomatic atrial fibrillation (AF). HYPOTHESIS: AF-free survival differs in patients with left common pulmonary vein (LCPV) after PVI with second-generation cryoballoon. METHODS: We included patients scheduled for first PVI for paroxysmal or persistent AF. Symptomatic and/or documented arrhythmia episodes (>30 seconds) were defined as AF recurrence, excluding a 3-month blanking period...
