BACKGROUND Poorly controlled ventricular rate associated with atrial fibrillation (AF) leads to tachycardia-induced left ventricular dysfunction. Atrioventricular (AV) nodal ablation and cardiac pacing is the standard of care in refractory congestive heart failure (CHF) due to AF with moderate to rapid ventricular response that failed conventional medical therapy. If the patient is not a candidate for AF ablation with pulmonary vein isolation and elimination of AF foci, this is an effective approach, but it does have some challenges when done in a patient with dextrocardia and situs inversus...

Aims: Left atrial (LA) remodelling is a key determinant of atrial fibrillation (AF) ablation outcome. Optimal methods to assess this process are scarce. LA sphericity is a shape-based parameter shown to be independently associated to procedural success. In a multicentre study, we aimed to test the feasibility of assessing LA sphericity and evaluate its capability to predict procedural outcomes. Methods and results: This study included consecutive patients undergoing first AF ablation during 2013...

BACKGROUND: Periprocedural anticoagulation is important in catheter ablation (CA) of atrial fibrillation (AF) and there is increasing evidence that uninterrupted vitamin K antagonist (VKA) therapy is superior to interrupted anticoagulation strategies. Since the emergence of direct oral anticoagulants (DOACs), numerous studies have shown promising results for their use in uninterrupted strategies. However, further studies are needed to further define the efficacy and safety of performing AF ablation with uninterrupted factor XA inhibitors or direct thrombin inhibitors...

Heart failure affects nearly 26 million people worldwide. Patients with heart failure are frequently affected with atrial fibrillation, and the interrelation between these pathologies is complex. Atrial fibrillation shares the same risk factors as heart failure. Moreover, it is associated with a higher-risk baseline clinical status and higher mortality rates in patients with heart failure. The mechanisms by which atrial fibrillation occurs in a failing heart are incompletely understood, but animal studies suggest they differ from those that occur in a healthy heart...

BACKGROUND: Heart failure (HF) promotes atrial fibrillation (AF) and AF worsens HF. This study aimed to investigate the long-term clinical outcomes after AF ablation in patients with HF. METHODS AND RESULTS: A total of 106 consecutive HF patients, including 51 (48.1%) with a reduced left ventricular ejection fraction (LVEF) (HFrEF) and 55 (51.9%) with a preserved LVEF (HFpEF), underwent AF ablation. All patients underwent successful pulmonary vein antrum isolation, and substrate modification was added in 38 (35...

One of the major complications of radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) is pulmonary vein stenosis (PVS). The natural history of PVS, especially when it involves more than one vein, leads to severe and irreversible pulmonary hypertension with end-stage right heart failure that can require, in extreme cases, even heart-lung transplantation. We report the case of a young patient who underwent RFCA for a single lasting episode of AF and developed PVS years later. He was treated with ballon venoplasty followed by stent implantation in left pulmonary vein because of PVS relief...

The main aim of current research on the field of atrial fibrillation (AF) treatment is to find new antiarrhythmic drugs with less side effects. Areas covered: Dronedarone and vernakalant showed promising result in term of efficacy and safety in selected patients. Ranolazine and colchicine are obtaining a role as a potential antiarrhythmic drug. Ivabradine is used in experimental studies for the rate control of AF. Moreover, new compounds (vanoxerine, moxonidine, budiodarone) are still under investigation. Monoclonal antibodies or selective antagonist of potassium channel are under investigation for long term maintenance of sinus rhythm...

Although preoperative atrial fibrillation (AF) is common in patients undergoing continuous-flow left ventricular assist device (CF-LVAD) implantation, how AF affects outcomes remains unclear. We analyzed our single-center experience with CF-LVAD implantation to determine whether preoperative AF was associated with inferior outcomes. From November 2003 through March 2016, 526 patients with chronic heart failure underwent implantation with the HeartMate II (HMII; n = 403) or HeartWare VAD (HVAD; n = 123). We identified 229 patients (165 HMII, 65 HVAD) who had preoperative AF and compared them with non-preoperative AF patients regarding the incidence of postoperative stroke, as well as long-term survival...

BACKGROUND: Atrial fibrillation is the commonest arrhythmia which raises the risk of heart failure, thromboembolic stroke, morbidity and death. Pharmacological treatments of this condition are focused on heart rate control, rhythm control and reduction in risk of stroke. Selective ablation of cardiac tissues resulting in isolation of areas causing atrial fibrillation is another treatment strategy which can be delivered by two minimally invasive interventions: percutaneous catheter ablation and thoracoscopic surgical ablation...

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...
