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

Multipoint left ventricular pacing improves response to cardiac resynchronization therapy with and without pressure-volume loop optimization: comparison of the long-term efficacy of two different programming strategies.

J Interv Card Electrophysiol 2018 Nov 27. Epub 2018 Nov 27.

Department of Arrhythmology, IRCCS Policlinico San Donato, Piazza E. Malan, 20097, San Donato Milanese, MI, Italy.

Purpose: Cardiac resynchronization therapy (CRT) with multipoint left ventricular (LV) pacing (MultiPoint™ Pacing [MPP]) improves long-term LV reverse remodeling, though questions persist about how to program LV pacing vectors and delays. We evaluated if an empirical method of programming MPP vectors and delays between pacing pulses improved CRT response similar to pressure-volume loop (PVL) optimized MPP programming.

Methods: Patients undergoing CRT implant (Quadra Assura MP™ CRT-D and Quartet™ LV lead) received MPP with programmed settings optimized either by PVL measurements at implant (PVL-OPT group) or empirically determined by maximizing the spatial separation between the two cathodes and minimal delays between the three ventricular pacing pulses (MAX-SEP group).

Evaluation of recurrent ventricular tachyarrhythmias in patients who survived out-of-hospital cardiac arrest due to ventricular fibrillation: eligibility for subcutaneous implantable defibrillator therapy.

J Interv Card Electrophysiol 2018 Nov 26. Epub 2018 Nov 26.

Department of Cardiology, Erasmus MC, Room RG-632, PO Box 2040, 3000 CA, Rotterdam, The Netherlands.

Purpose: The subcutaneous implantable defibrillator (S-ICD) was developed to avoid complications related to transvenous leads. A trade-off with the S-ICD is the inability to deliver antitachycardia pacing (ATP). Data is scarce about the recurrence and characteristics of ventricular tachyarrhythmias (VTa) during a follow-up in survivors of out-of-hospital cardiac arrest due to ventricular fibrillation (OHCA-VF).

High-power, low-flow, short-ablation duration-the key to avoid collateral injury?

J Interv Card Electrophysiol 2018 Oct 30. Epub 2018 Oct 30.

Mercy Health, 3300 Mercy Health Blvd, Cincinnati, OH, 45211, USA.

Background: A common approach to ablating along the posterior wall of the left atrium in atrial fibrillation ablation is to use low power with longer duration for durable lesions and reducing thermal injury. We hypothesize that similar lesions can be safely obtained at high power with low open-irrigation flow and low duration.

Methods: Twenty-two porcine ventricles were placed in a tissue bath with circulating 0. Read More

Predictors of low voltage areas in persistent atrial fibrillation: is it really a matter of time?

J Interv Card Electrophysiol 2018 Oct 29. Epub 2018 Oct 29.

Department of Electrophysiology, Deutsches Herzzentrum München, Technische Universität München, Lazarettstrasse 36, Munich, Germany.

Background: Time has been postulated as an important factor for electrical remodeling of the left atrium (LA) in persistent atrial fibrillation (AF) ('AF begets AF'). However, it is still a matter of debate if structural changes are the cause or consequence of AF. We sought to determine the clinical and invasive parameters, which correlate with LA scar as determined by voltage mapping, in patients with persistent AF. Read More
