Comparison between linear and focal ablation of complex fractionated atrial electrograms in patients with non-paroxysmal atrial fibrillation: a prospective randomized trial.

Europace 2019 Jan 12. Epub 2019 Jan 12.

Division of Cardiology, Department of Internal Medicine, Korea University Medical Center, 73 Inchon-ro, Seongbuk-gu, Seoul 02841, Republic of Korea.

Aims: Findings regarding efficacy of substrate modification for non-paroxysmal atrial fibrillation (AF) are inconsistent. We prospectively compared clinical outcomes of complex fractionated atrial electrogram (CFAE)-guided focal ablation (CFA) and CFAE-guided linear ablation (CLA) in patients with non-paroxysmal AF.

Methods And Results: We randomized 150 patients with non-paroxysmal AF into CFA and CLA groups in a 1:1 ratio. Read More

Effect of PR interval and pacing mode on persistent atrial fibrillation incidence in dual chamber pacemaker patients: a sub-study of the international randomized MINERVA trial.

Europace 2019 Jan 10. Epub 2019 Jan 10.

Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, S.Orsola-Malpighi University Hospital, Bologna, Italy.

Aims: Per standard of care, dual-chamber pacemakers are programmed in DDDR mode with fixed atrioventricular (AV) delay or with long AV delay to minimize ventricular pacing. We aimed to evaluate whether the PR interval may be a specific criterion of choice between standard DDDR, to preserve AV synchrony in long PR patients, and managed ventricular pacing (MVP), to avoid ventricular desynchronization imposed by right ventricle apical pacing, in short PR patients.

Methods And Results: In the MINERVA trial, 1166 patients were randomized to Control DDDR, MVP, or atrial anti-tachycardia pacing plus MVP (DDDRP + MVP). Read More

Quick atrial access by subxiphoid approach in extracorporeal cardiopulmonary resuscitation after bidirectional Glenn procedure.

Perfusion 2019 Jan 14:267659118823999. Epub 2019 Jan 14.

Department of Cardiovascular Surgery, Nagano Children's Hospital, Azumino, Japan.

Bidirectional Glenn procedure outcomes are very good; therefore, extracorporeal membrane oxygenation use as extracorporeal cardiopulmonary resuscitation is uncommon. We describe a 13-month-old female who required extracorporeal cardiopulmonary resuscitation for ventricular tachycardia provoked by transient myocarditis 6 months post-bidirectional Glenn procedure. After extracorporeal membrane oxygenation induction with cannulation on the cervical vessels, small skin incision was created on the subxiphoid area without sternotomy and the atrium was cannulated.

Cardiovascular Division, Department of Medicine, Harvard-Thorndike Electrophysiology Institute, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA (M.B., A.S.-D., E.L., C.S., E.A.).

Background: The mitral isthmus is the critical element of perimitral reentrant tachycardias. Prolongation in transisthmus conduction time and differential pacing techniques are commonly used to determine block. However, these may not distinguish block from slow conduction or conduction via epicardial bridging connections. Read More

Arrhythmia Mechanisms Revealed by Ripple Mapping.

Arrhythm Electrophysiol Rev 2018 Dec;7(4):261-264

Department of Bioengineering, Imperial College London UK.

Ripple mapping is a novel method of 3D intracardiac electrogram visualisation that allows activation of the myocardium to be tracked visually without prior assignment of local activation times and without interpolation into unmapped regions. It assists in the identification of tachycardia mechanism and optimal ablation site, without the need for an experienced computer-operating assistant. This expert opinion presents evidence demonstrating the benefit of Ripple Mapping, compared with traditional electroanatomic mapping techniques, for the diagnosis and management of atrial and ventricular tachyarrhythmias during electrophysiological procedures.

Canine and human sinoatrial node: differences and similarities in the structure, function, molecular profiles, and arrhythmia.

J Vet Cardiol 2018 Dec 14. Epub 2018 Dec 14.

Department of Physiology and Cell Biology, Dorothy M. Davis Heart & Lung Research Institute, The Ohio State University Wexner Medical Center, Columbus, OH, USA. Electronic address:

The sinoatrial node (SAN) is the primary pacemaker in canine and human hearts. The SAN in both species has a unique three-dimensional heterogeneous structure characterized by small pacemaker myocytes enmeshed within fibrotic strands, which partially insulate the cells from aberrant atrial activation. The SAN pacemaker tissue expresses a unique signature of proteins and receptors that mediate SAN automaticity, ion channel currents, and cell-to-cell communication, which are predominantly similar in both species.

Vagus nerve stimulation reduces ventricular arrhythmias and increases ventricular electrical stability.

Pacing Clin Electrophysiol 2018 Dec 15. Epub 2018 Dec 15.

Xinjiang Key Laboratory of Medical Animal Model Research, Clinical Medical Research Institute, First Affiliated Hospital of Xinjiang Medical University, Urumqi, China.

Background: Transcutaneous stimulation of the auricular branch of the vagus nerve (AB-VNS) is a potentially noninvasive, inexpensive, and safe approach for vagus nerve stimulation that suppresses the induction and duration of atrial fibrillation and reduces sympathetic nerve outflow in healthy humans. Researchers have not determined whether AB-VNS affects ventricular arrhythmias.

Objective: To evaluate the antiarrhythmic effects of noninvasive AB-VNS on ventricular arrhythmias induced by myocardial infarction (MI). Read More

Predictors of improvement in arrhythmia-specific symptoms and health-related quality of life after catheter ablation of atrial fibrillation.

Clin Cardiol 2018 Dec 11. Epub 2018 Dec 11.

Department of Medical and Health Sciences, Linköping University, Linköping, Sweden.

Background: The primary goal of radiofrequency ablation (RFA) of atrial fibrillation (AF) is to improve symptoms and health-related quality of life (HRQoL). However, most studies have focused on predictors of AF recurrence rather than on predictors of improvement in symptoms and HRQoL.

Hypothesis: We sought to explore predictors of improvement in arrhythmia-specific symptoms and HRQoL after RFA of AF, and to evaluate the effects on symptoms, HRQoL, anxiety, and depression. Read More

Single-brand dual-chamber discriminators to prevent inappropriate shocks in patients implanted with prophylactic implantable cardioverter defibrillators: a propensity-weighted comparison of single- and dual-chamber devices.

J Interv Card Electrophysiol 2018 Dec 6. Epub 2018 Dec 6.

Cardiology Department, Hospital Universitario Infanta Leonor, Gran Vía del Este, 28030, Madrid, Spain.

Purpose: Comparisons of the efficacy of dual- vs. single-chamber implantable cardioverter defibrillators (ICDs) in preventing inappropriate shocks have had contradictory results. We investigated whether dual-chamber devices have a lower risk of inappropriate shocks and the specific role of supraventricular tachycardia (SVT) discriminators. Read More

Predictors, Burden, and the Impact of Arrhythmia on Patients Admitted for Acute Myocarditis.

Am J Cardiol 2019 Jan 27;123(1):139-144. Epub 2018 Sep 27.

Division of Cardiology, Wayne State University/Detroit Medical Center, Detroit, Michigan.

A significant proportion of patients with acute myocarditis experience sudden cardiac death presumably due to cardiac arrhythmia. In this study, we explore the burden, the predictors of arrhythmia in acute myocarditis and the association between arrhythmias and adverse in-hospital outcomes. After evaluating the frequency of various tachyarrhythmias and bradyarrhythmia in myocarditis population, we built a logistic model to determine the independent predictors of arrhythmias in myocarditis and a 1:1 propensity-matched analysis to examine the impact of arrhythmias.

Impact of left atrial box surface ratio on the recurrence after ablation for persistent atrial fibrillation.

Pacing Clin Electrophysiol 2018 Dec 5. Epub 2018 Dec 5.

Department of Cardiology, Leiden University Medical Center, University of Leiden, Leiden, The Netherlands.

Background: The posterior wall of the left atrium (LA) is a well-known substrate for atrial fibrillation (AF) maintenance. Isolation of the posterior wall between the pulmonary veins (box lesion) may improve ablation success. Box lesion surface area size varies depending on the individual anatomy. Read More
