Simultaneous occurrence of peri-mitral flutter using an epicardial connection and pulmonary vein trigger driving atrial fibrillation in the posterior wall of the left atrium.

J Cardiovasc Electrophysiol 2019 Feb 14. Epub 2019 Feb 14.

Clinica Montevergine, Mercogliano (AV), Italy.

It is not unusual to find areas of organized atrial activity in the left atrium during atrial fibrillation but when it happens these rhythms are mostly interrelated. Our report shows that extensive ablation can dissociate different portions of the same chamber to the point that simultaneous occurring atrial flutter and atrial fibrillation can be studied and terminated independently from each other This article is protected by copyright.

Expert Rev Cardiovasc Ther 2019 Feb 4:1-11. Epub 2019 Feb 4.

a Department of Cardiology , Instituto Cardiovascular de Buenos Aires , Buenos Aires , Argentina.

Introduction: The past few years have given rise to extensive research on an interatrial block and its clinical relevance, mainly its association with supraventricular arrhythmias. In 2015, the authors of this article reviewed the Bayes syndrome for the first time and after three years there has been so much evidence accumulated that it seems reasonable to rewrite an update, based fundamentally on the new findings. Focused on its relationship with cardioembolic strokes, today efforts are being targeted at understanding its pathophysiology, its diagnosis, and its prognostic implications, in order to learn if it should be treated.

Patient-Specific Identification of Atrial Flutter Vulnerability-A Computational Approach to Reveal Latent Reentry Pathways.

Front Physiol 2018 14;9:1910. Epub 2019 Jan 14.

Institute of Biomedical Engineering, Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany.

Atypical atrial flutter (AFlut) is a reentrant arrhythmia which patients frequently develop after ablation for atrial fibrillation (AF). Indeed, substrate modifications during AF ablation can increase the likelihood to develop AFlut and it is clinically not feasible to reliably and sensitively test if a patient is vulnerable to AFlut. Here, we present a novel method based on personalized computational models to identify pathways along which AFlut can be sustained in an individual patient. Read More

Long-term outcome of catheter ablation for atrial tachyarrhythmias in patients with atrial septal defect.

J Interv Card Electrophysiol 2019 Jan 3. Epub 2019 Jan 3.

Department of Cardiology, Shanghai Chest Hospital, Shanghai Jiao Tong University, Shanghai, China.

Purpose: This study aimed to evaluate efficacy, safety, and long-term outcome of radiofrequency catheter ablation (RFCA) for atrial tachyarrhythmia (ATa) in patients with atrial septal defect (ASD).

Methods: Seventy-five ASD patients with ATa (52% atrial fibrillation, AF) were enrolled. Electrophysiological study and RFCA were performed, with endpoints of index and multiple procedures as follows: (a) atrial tachycardia/atrial flutter (AT/AFL), absence of inducibility of any atrial arrhythmia and (b) AF, circumferential pulmonary vein ablation (CPVA, paroxysmal AF), bidirectional block of lines, and disappearance of complex fractionated atrial electrograms (persistent and long-standing persistent (LSP)-AF).

DC cardioversion of atrial fibrillation and atrial flutter in the emergency department: improving specialist protocols for the generalist.

BMJ Open Qual 2018 1;7(4):e000260. Epub 2018 Dec 1.

Department of Cardiology, Severn Deanery, Bristol, UK.

Background: Direct current cardioversion (DCCV) is a safe and effective treatment for recent-onset atrial fibrillation (AF) or flutter and when performed in the emergency department (ED), it can provide an excellent treatment option for patients as well as reducing unnecessary hospital admissions and healthcare costs. However, appropriate periprocedural anticoagulation is absolutely essential to reduce the risk of adverse outcomes, chiefly thromboembolic stroke. Our intention was for 100% of patients undergoing DCCV in the ED to receive appropriate periprocedural anticoagulation. Read More
