Association of body mass index with cardiac resynchronization therapy intention and left ventricular lead implantation failure: insights from the NCDR implantable cardioverter-defibrillator registry.

J Interv Card Electrophysiol 2019 Apr 19. Epub 2019 Apr 19.

Cardiac Electrophysiology Section, Division of Cardiology, Department of Medicine, University of California, San Diego, San Diego, CA, USA.

Background: Cardiac resynchronization therapy with defibrillator (CRT-D) implantation involves left ventricular (LV) lead placement for biventricular pacing and is more complex than implantable cardioverter-defibrillator (ICD)-only implantation. Differences in the prescription of CRT-D versus ICD may result from clinician biases based on patient body habitus, and body habitus may be associated with LV lead implantation failure.

Objective: We sought to evaluate whether patient body mass index (BMI) was associated with planned use and implantation failure of CRT-D therapy. Read More

Circulating primary bile acid is correlated with structural remodeling in atrial fibrillation.

J Interv Card Electrophysiol 2019 Mar 26. Epub 2019 Mar 26.

Department of Cardiology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, 1630 Dongfang Rd., Shanghai, 200127, China.

Background: Circulating primary bile acid was involved in the regulation of cardiac ionic channel currents and ventricular myocyte apoptosis, but it was unknown whether or not it played a role in structural remodeling of AF. This study was aimed to testify the hypothesis that elevated chenodeoxycholic acid (CDCA) concentration correlated with left atrial low voltage area (LVA) and could induce apoptosis of atrial myocytes in AF.

Methods And Results: Serum concentrations of 12 types of bile acids were determined in patients with paroxysmal (n = 21), persistent AF (n = 20), and type A pre-excitation and paroxysmal supraventricular tachycardia (PSVT) (n = 19) and were correlated with LVA in AF, which was obtained by electroanatomical mapping during ablation.

Clinical evidence of autonomic dysfunction due to atrial fibrillation: implications for rhythm control strategy.

J Interv Card Electrophysiol 2019 Apr 19;54(3):299-307. Epub 2019 Jan 19.

Illawarra Health and Medical Research Institute, Building 32, University of Wollongong, Wollongong, NSW, 2522, Australia.

Purpose: The role of the autonomic nervous system in the genesis of atrial fibrillation (AF) has been well studied; however, the converse remains poorly understood. Pulmonary veins (PV) contain receptors important in cardiac reflexes. Here, we evaluated reflex responses in patients with paroxysmal AF (PAF) to lower body negative pressure (LBNP). Read More

Overview of the current electrophysiology (EP) state of affairs in Russia.

J Interv Card Electrophysiol 2019 Jan 5. Epub 2019 Jan 5.

Cardiovascular Surgery Department, Military Medical Academy named after S.M. Kirov, Saint Petersburg, Russia.

Russia is the largest country in the world based on the landmass, covering more than one-eighth of the earth's inhabited area. Russia faces challenges in electrophysiology (EP) care including insufficient and uneven financing, complicated system for identifying optimal treatment for individual patients, relative paucity of reasonable educational and certification scope for electrophysiologists, suboptimal national statistical data gathering regarding heart rhythm disorders and EP devices in use, and weak networking of medical information. In comparison with the average level of EP utilization in ESC countries, Russia utilizes around 50% in pacemaker; 10% in ICD; 8% in cardiac resynchronization therapy; 55% in ablations; and 45% in AF ablations.

Cryoballoon ablation of atrial fibrillation is effectively feasible without previous imaging of pulmonary vein anatomy: insights from the 1STOP project.

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

Cardiac Arrhythmia Research Centre, Centro Cardiologico Monzino IRCCS Milan Azienda, Milan, Italy.

Background: Pulmonary vein isolation by cryoablation (PVI-C) is a standard therapy for the treatment of atrial fibrillation (AF); however, PVI-C can become a challenging procedure due to the anatomy of the left atrium and pulmonary veins (PVs). Importantly, the utility of imaging before the procedure is still unknown regarding the long-term clinical outcomes following PVI-C. The aim of the analysis is to evaluate the impact of imaging before PVI-C on procedural data and AF recurrence. Read More

The modified ablation index: a novel determinant of acute pulmonary vein reconnections after pulmonary vein isolation.

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

Division of Cardiology, Department of Medicine, Nihon University School of Medicine, 30-1 Ohyaguchi-Kamicho, Itabashi-ku, Tokyo, 173-8610, Japan.

Background: Although pulmonary vein isolation (PVI) guided by the ablation index (AI) has been well-developed, acute PV reconnections (PVRs) still occur. This study aimed to compare the prognostic performance of the modified AI and its optimal cut-off value for the prediction of acute PVRs to ensure durable PVI.

Methods: Three-dimensional left atrium (LA) voltage maps created before an extensive encircling PVI in 64 patients with atrial fibrillation (AF) (45 men, 62 ± 10 years) were examined for an association between electrogram voltage amplitude recorded from the PV-LA junction and acute post-PVI PVRs (spontaneous PVRs and/or ATP-provoked dormant PV conduction).

The role of microRNAs in the development, regulation, and treatment of atrial fibrillation.

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

Intermountain Medical Center Heart Institute, Murray, UT, USA.

Background: MicroRNAs (miRNA)s regulate expression of genes involved in various processes including cardiac automaticity, conduction, excitability, and fibrosis and therefore may provide a diagnostic utility to identify high-risk patients for atrial fibrillation (AF). In this study, we tested the hypothesis that specific profiles of circulating miRNAs can identify patients with AF and can also help to identify patients at high risk of AF recurrence after ablation.

Methods: Two patient populations were studied: 140 AF cases (93 paroxysmal and 47 persistent) and 50 healthy controls, and 141 AF ablation cases with (n = 86) and without (n = 55) 1-year recurrence. Read More

Panic features strongly predict the subjective but not the objective benefit of pulmonary vein isolation.

J Interv Card Electrophysiol 2018 Dec 18. Epub 2018 Dec 18.

OLVG Hospital, Heart Center, Amsterdam, Netherlands.

Purpose: Clinically observed discrepancies between electrocardiogram findings and subjective report of symptoms related to atrial fibrillation (AF) often remain unexplained. One could hypothesize that after a technically successful ablation, preoperative panic behavior might affect the report of AF-related symptoms. However, research on comorbid panic behavior in patients with AF is limited. Read More

Focal atrial tachycardia ablation: Highly successful with conventional mapping.

J Interv Card Electrophysiol 2018 Dec 1. Epub 2018 Dec 1.

Cardiology Department, NIMTS Hospital, Athens, Greece.

Background/objective: Radiofrequency catheter ablation (RFCA) of focal atrial tachycardia (FAT) traditionally is guided by conventional endocardial mapping of earliest atrial activation; however, more recently electro-anatomical mapping is heralded as a more effective, albeit more expensive, tool to guide ablation. Herein we present the results of conventional mapping-guided RFCA. Apropos, we conducted a literature search of studies reporting > 10 FAT patients submitted to RFCA. Read More
