Ablation of Ischemic Ventricular Tachycardia Using a Multipolar Catheter and 3-dimensional Mapping System for High-density Electro-anatomical Reconstruction.

J Vis Exp 2019 Jan 31(143). Epub 2019 Jan 31.

Department of Internal Medicine/Cardiology, Hietzing Hospital.

Ventricular tachycardia (VT) in patients with ischemic cardiomyopathy mainly results from endocardial scars after myocardial infarction; those scars represent zones of slow conduction that allow the occurrence and maintenance of reentrant circuits. Catheter ablation enables substrate modification of those low voltage areas and thus can help to alter the scar tissue in such a way that arrhythmias cannot appear anymore. Hospitalizations of concerned patients decrease, quality of life and outcome rise. Read More

Venoarterial ECMO for Adults: JACC Scientific Expert Panel.

J Am Coll Cardiol 2019 Feb;73(6):698-716

Division of Cardiology, Icahn School of Medicine at Mount Sinai, New York, New York.

Venoarterial extracorporeal membrane oxygenation (ECMO) is a rescue therapy that can stabilize patients with hemodynamic compromise, with or without respiratory failure, for days or weeks. In cardiology, the main indications for ECMO include cardiac arrest, cardiogenic shock, post-cardiotomy shock, refractory ventricular tachycardia, and acute management of complications of invasive procedures. The fundamental premise underlying ECMO is that it is a bridge-to recovery, to a more durable bridge, to definitive treatment, or to decision. Read More

Effects of antiarrhythmics on the electrical restitution in perfused guinea-pig heart are critically determined by the applied cardiac pacing protocol.

Authors:
Oleg E Osadchii

Exp Physiol 2019 Feb 13. Epub 2019 Feb 13.

Department of Biomedical Sciences, University of Copenhagen, Blegdamsvej 3, 2200, Copenhagen N, Denmark.

NEW FINDINGS: What is the central question of this study? Are modifications in the restitution of ventricular action potential duration induced by antiarrhythmic drugs the same when assessed with premature extrastimulus application at variable coupling intervals (the standard stimulation protocol) and with steady state pacing at variable rates (the dynamic stimulation protocol)? What is the main finding and its importance? With class I and class III antiarrhythmics, the effects on electrical restitution determined with the standard stimulation protocol dissociate from those obtained during dynamic pacing. These findings indicate a limited value of the electrical restitution assessments based on extrasystolic stimulations alone, as performed in the clinical studies, in estimating the outcomes of antiarrhythmic drug therapies. ABSTRACT: A steep slope of the ventricular action potential duration (APD) to diastolic interval (DI) relationships (the electrical restitution) can precipitate tachyarrhythmia, whereas a flattened slope is antiarrhythmic.

Cardiovasc Diagn Ther 2018 Dec;8(6):754-764

Department of Pediatric Cardiology and Congenital Heart Disease, Hôpital Marie Lannelongue, Université Paris-Sud, Le Plessis Robinson, France.

Today, more than two thirds of patients with congenital heart disease (CHD) are adults. Cardiac surgery plays an essential role in restoring and maintaining cardiac function, aside from evolving medical treatment and catheter-based interventions. The aim of the present publication was to describe the spectrum of operations performed on adults with CHD (ACHD) by reviewing current literature. Read More

Feasibility of Cardiac Magnetic Resonance Wideband Protocol in Patients With Implantable Cardioverter Defibrillators and Its Utility for Defining Scar.

Am J Cardiol 2019 Jan 31. Epub 2019 Jan 31.

University of Chicago Medical Center, Chicago, Illinois. Electronic address:

Implantable cardioverter defibrillators (ICDs) have been a relative contraindication to cardiovascular magnetic resonance imaging. Although cardiovascular magnetic resonance provides valuable information regarding scar in patients with ventricular arrhythmias or cardiomyopathy, ICDs in these patients frequently cause artifacts hindering accurate interpretation of both cine and late gadolinium enhancement (LGE) images. We sought to quantify the frequency and severity of artifact on LGE images and assess whether a modified wideband LGE protocol could improve the diagnostic yield of scar identification in agreement with invasive electroanatomic mapping (EAM).

Early initiation of extracorporeal life support in refractory out-of-hospital cardiac arrest: Design and rationale of the INCEPTION trial.

Am Heart J 2018 Dec 14;210:58-68. Epub 2018 Dec 14.

Department of Intensive Care, Maastricht University Medical Center, Maastricht, The Netherlands; NUTRIM, School for Nutrition and Translational Research in Metabolism, Maastricht University, Maastricht, The Netherlands; Department of Surgery, Maastricht University Medical Center, Maastricht, The Netherlands.

Return of spontaneous circulation occurs in less than 10% of patients with cardiac arrest undergoing cardiopulmonary resuscitation (CPR) for more than 15 minutes. Studies suggest that extracorporeal life support during cardiopulmonary resuscitation (ECPR) improves survival rate in these patients. These studies, however, are hampered by their non-randomized, observational design and are mostly single-center. Read More

Characterization of microminipig as a laboratory animal for safety pharmacology study by analyzing fluvoxamine-induced cardiovascular and dermatological adverse reactions.

Cardiovasc Toxicol 2019 Feb 8. Epub 2019 Feb 8.

Department of Pharmacology, Toho University Graduate School of Medicine, 5-21-16 Omori-nishi, Ota-ku, Tokyo, 143-8540, Japan.

Fluvoxamine is a selective serotonin-reuptake inhibitor, of which IC values for serotonin- and noradrenaline-uptake process were reported to be 3.8 and 620 nmol/L, respectively, also known to directly inhibit cardiac Na, Ca, and K channels. We characterized microminipig as a laboratory animal by analyzing fluvoxamine-induced cardiovascular and dermatological responses under halothane anesthesia. Read More

Atrioventricular reentrant tachycardia in a child with tricuspid atresia: A case report of catheter ablation.

Medicine (Baltimore) 2019 Feb;98(6):e14320

Department of Cardiology, Hunan Children's Hospital.

Rationale: Atrioventricular reentrant tachycardia (AVRT) is the most common supraventricular tachycardia occurring in children. However, in complex congenital heart disease patients with a different heart anatomy and conduction system morphology, accessory pathway modification may be particularly challenging because of distortion of typical anatomic landmarks.

Patient Concerns: A 10-year-old boy with tricuspid atresia and history of bidirectional Glenn operation had recurrent chest distress and palpitation for 3 months. Read More

Extracorporeal cardiopulmonary resuscitation in out-of-hospital cardiac arrest: Ethical considerations.

Resuscitation 2019 Feb 4;137:1-6. Epub 2019 Feb 4.

Sunnybrook Center for Prehospital Medicine, Canada; Department of Family Community Medicine, Division of Emergency Medicine, University of Toronto, Canada.

Out-of-hospital cardiac arrest (OHCA) continues to be a leading cause of mortality worldwide. In Canada over 40,000 cardiac arrests that occur each year, a majority occur unexpectedly outside of the hospital setting. However, the reality is that without rapid and appropriate treatment within minutes, most victims will die before reaching the hospital. Read More

Non-fluoroscopic catheter ablation of arrhythmias with origin at the summit of the left ventricle.

J Interv Card Electrophysiol 2019 Feb 7. Epub 2019 Feb 7.

Centre Hospitalaire Universitaire de Sherbrooke (CHUS), Quebec, Canada.

Background: Catheter ablation of ventricular arrhythmias (VAs) arising from the left ventricular Summit (LVS) is challenging and requires high-dose fluoroscopy to limit vascular damage of the coronary arteries. Ionizing radiation can increase the incidence of malignancies to both patient and operator. This study describes outcomes of catheter ablation of LVS VAs using intracardiac echo-facilitated 3D electroanatomical mapping (ICE-3D) to avoid fluoroscopy. Read More

A Homozygous Mutation in a Japanese Patient with Catecholaminergic Polymorphic Ventricular Tachycardia.

Case Rep Genet 2019 8;2019:9056596. Epub 2019 Jan 8.

Department of Cardiology, Keio University School of Medicine, Tokyo, Japan.

A 62-year-old female had suffered from recurrent syncopal episodes triggered by physical and emotional stress since childhood. She had no family history of sudden death. An intensive examination could not detect any structural disease, and exercise stress testing provoked polymorphic ventricular ectopy followed by polymorphic ventricular tachycardia accompanied with syncope leading to a diagnosis of catecholaminergic polymorphic ventricular tachycardia (CPVT).

Omnipolarity applied to equi-spaced electrode array for ventricular tachycardia substrate mapping.

Europace 2019 Feb 4. Epub 2019 Feb 4.

Department of Medicine, Toronto General Hospital, University Health Network, Toronto, Ontario, Canada.

Aims : Bipolar electrogram (BiEGM)-based substrate maps are heavily influenced by direction of a wavefront to the mapping bipole. In this study, we evaluate high-resolution, orientation-independent peak-to-peak voltage (Vpp) maps obtained with an equi-spaced electrode array and omnipolar EGMs (OTEGMs), measure its beat-to-beat consistency, and assess its ability to delineate diseased areas within the myocardium compared against traditional BiEGMs on two orientations: along (AL) and across (AC) array splines.

Methods And Results: The endocardium of the left ventricle of 10 pigs (three healthy and seven infarcted) were each mapped using an Advisor™ HD grid with a research EnSite Precision™ system. Read More
