  • J-Wave syndromes expert consensus conference report: Emerging concepts and
           gaps in knowledge

    • Authors: Charles Antzelevitch; Gan-Xin Yan, Michael J. Ackerman, Martin Borggrefe, Domenico Corrado, Jihong Guo, Ihor Gussak, Can Hasdemir, Minoru Horie, Heikki Huikuri, Changsheng Ma, Hiroshi Morita, Gi-Byoung Nam, Frederic Sacher, Wataru Shimizu, Sami Viskin, Arthur A.M. Wilde
      Abstract: The J-wave syndromes (JWSs), consisting of the Brugada syndrome (BrS) and early repolarization syndrome (ERS), have captured the interest of the cardiology community over the past 2 decades following the identification of BrS as a new clinical entity by Pedro and Josep Brugada in 1992 [1]. The clinical impact of ERS was not fully appreciated until 2008 [2–4]. Consensus conferences dedicated to BrS were held in 2000 and 2004 [5,6], but a consensus conference specifically focused on ERS has not previously been convened other than that dealing with terminology, and guidelines for both syndromes were last considered in 2013 [7].

  • The inferior displacement of the His bundle and fast pathway in a patient
           with common type atrioventricular nodal tachycardia: Three-dimensional
           computed tomography analysis

    • Authors: Kunihiko Kiuchi; Koji Fukuzawa, Mori Shumpei, Tatsuya Nishii
      Abstract: A 66-year-old woman with palpitations was referred to our center for catheter ablation due to drug-refractory, common type atrioventricular nodal tachycardia (AVNRT). A selective slow pathway ablation was attempted. A fast junctional rhythm with transient ventriculoatrial block followed by transient prolongation of the A–H interval occurred immediately after the radiofrequency (RF) application at the coronary sinus ostium (CSOS) level. To assess the location of the fast pathway and His bundle, we sought to visualize the anatomy of the triangle of Koch (TOK) by three-dimensional computed tomography (CT).

  • Cardiac electrical device-related bacterial infections: Prevention,
           diagnosis, and management

    • Authors: Takashi Kurita
      Abstract: Significant developmentin modern cardiac (or cardiovascular) electrical devices (CIEDs), including permanent pacemakers, implantable cardioverter-defibrillators (ICDs), and cardiac resynchronization therapy, is contributing to the improvement in both the survival rate and quality of life in patients with cardiac arrhythmias and/or heart failure. The number of CIED implantations has increased significantly over the past decade based on clinical evidence. However, CIED-related bacterial infections remain one of the biggest and most serious complications of their use.

  • A multicenter study of the need of additional freezing for cryoballoon
           ablation in patients with atrial fibrillation: The AD-Balloon study

    • Authors: Koji Miyamoto; Atsushi Doi, Naoki Amaya, Yoshiaki Morita, Takashi Noda, Masanori Asakura, Toshimitsu Hamasaki, Hiroshi Tada, Masahiko Takagi, Satoshi Yasuda, Kengo Kusano
      Abstract: Pulmonary vein isolation (PVI) is a cornerstone of catheter ablation in patients with paroxysmal atrial fibrillation (PAF), and balloon-based ablation has been recently performed worldwide. Ablation using the second-generation cryoballoon (CB2) (Arctic Front AdvanceTM, Medtronic, MN, USA) is useful for PVI; however, there is some debate concerning the optimal freezing time and number of cycles after PVI is achieved.

  • Spatiotemporal characteristics of atrial fibrillation electrograms: A
           novel marker for arrhythmia stability and termination

    • Authors: Shivshankar Thanigaimani; Anthony G. Brooks, Pawel Kuklik, Darragh J. Twomey, Samantha Franklin, Erik Noschka, Darius Chapman, Rajeev K. Pathak, Rajiv Mahajan, Prashanthan Sanders, Dennis H. Lau
      Abstract: Sequentially mapped complex fractionated atrial electrograms (CFAE) and dominant frequency (DF) sites have been targeted during catheter ablation for atrial fibrillation (AF). However, these strategies have yielded variable success and have not been shown to correlate consistently with AF dynamics. Here, we evaluated whether the spatiotemporal stability of CFAE and DF may be a better marker of AF sustenance and termination.

  • EHRA/HRS/APHRS/SOLAECE expert consensus on Atrial cardiomyopathies:
           Definition, characterisation, and clinical implication

    • Abstract: The atria provide an important contribution to cardiac function [1,2]. Besides their impact on ventricular filling, they serve as a volume reservoir, host pacemaker cells and important parts of the cardiac conduction system (e.g. sinus node, AV node), and secrete natriuretic peptides like atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) that regulate fluid homoeostasis. Atrial myocardium is affected by many cardiac and non-cardiac conditions [3] and is, in some respects, more sensitive than ventricular [4].

           review

    • Authors: Mohammad Ali Akbarzadeh; Reza Mollazadeh, Salma Sefidbakht, Soraya Shahrzad, Negar Bahrololoumi Bafruee
      Abstract: Right ventricular perforation is a rare but serious complication of permanent pacemaker and implantable cardioverter-defibrillator implantation, with a reported prevalence rate of 0.1–6%. Generally, there is a high incidence of asymptomatic lead perforation with otherwise normal function. Some patients present with a stabbing chest pain and shortness of breath or pacemaker malfunction. However, in some cases, tamponade or adjacent tissue injury may be seen. The exact risk factors for lead perforation are not yet clear.

  • Electrophysiologic similarities of overdose between digoxin and
           bufadienolides found in a Chinese aphrodisiac

    • Authors: Maxwell Bressman; Daniel Repplinger, William Slater, Mitchell Platt
      Abstract: Classically derived from toad venom, bufadienolides are a group of cardioactive steroids with properties similar to digoxin. Some traditional Chinese medications, including several aphrodisiacs, contain bufadienolides. Owing to their physiologic similarities to digoxin, bufadienolides have been shown to produce a toxic profile similar to that of digoxin and there have been multiple case reports of the use of these aphrodisiacs resulting in death. This report will describe a case that illustrates the electrophysiologic similarities between bufadienolide toxicity and digoxin toxicity as well as the treatment of bufadienolide toxicity.

  • Functional characteristics of left ventricular synchronization via right
           ventricular outflow-tract pacing detected by two-dimensional strain
           echocardiography

    • Authors: Yasutaka Hirayama; Yuichiro Kawamura, Nobuyuki Sato, Tatsuya Saito, Hideichi Tanaka, Yasuaki Saijo, Kenjiro Kikuchi, Katsumi Ohori, Naoyuki Hasebe
      Abstract: Recently, due to the detrimental effects on the ventricular function associated with right ventricular apical (RVA) pacing, right ventricular septal (RVS) pacing has become the preferred pacing method. However, the term RVS pacing refers to both right ventricular outflow-tract (RVOT) and mid-septal (RVMS) pacing, leading to a misinterpretation of the results of clinical studies. The purpose of this study, therefore, was to elucidate the functional differences of RVA, RVOT, and RVMS pacing in patients with atrioventricular block.

      Abstract: Drug treatment and/or implantable cardioverter defibrillator (ICD) implantation are the most widely accepted first-line therapies for channelopathic patients who have recurrent syncope, sustained ventricular tachycardia (VT), or documented ventricular fibrillation (VF), or are survivors of cardiac arrest. In recent years, there have been significant advances in mapping techniques and ablation technology, coupled with better understanding of the mechanisms of ventricular tachyarrhythmia in channelopathies.

  • Bidirectional ventricular tachycardia in cardiac sarcoidosis

    • Authors: Mina M. Benjamin; Kevin Hayes, Michael E. Field, Melvin M. Scheinman, Kurt S. Hoffmayer
      Abstract: A 73-year-old man with history of pulmonary sarcoidosis was found to have runs of non-sustained bidirectional ventricular tachycardia (BVT) with two different QRS morphologies on a Holter monitor. Cardiac magnetic resonance delayed gadolinium imaging revealed a region of patchy mid-myocardial enhancement within the left ventricular basal inferolateral myocardium. An 18-fluorodeoxyglucose positron emission tomography (FDG-PET) showed increased uptake in the same area, consistent with active sarcoid, with no septal involvement.

      Abstract: Left atrial–esophageal fistulas (LAEFs) are serious complications with high mortality after atrial fibrillation radiofrequency ablation (AFRA). Decreasing the incidence of esophageal thermal lesions (EsoTLs) that may lead to LAEFs is important. The aim of this study was to suppress EsoTL development and determine the appropriate alarm setting for a temperature-monitoring probe by using steerable sheath (STS) methods.

      Abstract: The direction of impulse propagation across the coronary sinus (CS) musculature (CSM) is an important piece of the mechanistic puzzle underlying atrial tachyarrhythmias. We hypothesized that in the general population, the sequence of left atrial (LA) to CSM electrograms recorded in the CS reflects the direction of impulse propagation over the CSM.

      Abstract: The entirely subcutaneous implantable cardioverter-defibrillator (ICD) system was developed to provide a life-saving defibrillation therapy that does not affect the heart and vasculature. The subcutaneous ICD is preferred over the transvenous ICD for patients with a history of recurrent infection presenting major life-threatening rhythms. In this case report, we describe the first successful intermuscular implantation of a completely subcutaneous ICD in a Japanese patient with pectus excavatum. There were no associated complications with the device implantation or lead positioning.

  • Successful percutaneous epicardial catheter ablation of ventricular
           tachycardia arising from the crux of the heart in a patient with prior
           coronary artery bypass grafting

    • Authors: Naoki Yoshida; Takumi Yamada
      Abstract: A 63-year-old man with a history of remote inferior myocardial infarction and coronary artery bypass grafting (CABG) underwent catheter ablation of ventricular tachycardia (VT). Epicardial catheter ablation of the VT was successful at the crux of the heart despite limited mapping within the pericardial space due to pericardial adhesion. Percutaneous subxiphoidal pericardial approach is usually impossible in patients with a history of open heart surgery due to pericardial adhesions. This report suggested that epicardial VT arising from the crux of the heart could be successfully treated by catheter ablation via subxiphoidal pericardial approach despite pericardial adhesions complicated by prior CABG.

      Abstract: Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM). While upgrading to biventricular pacing (BiVP) is an effective therapy for PICM, permanent His-bundle pacing (HBP) can be a physiological alternative to BiVP. We present a patient with PICM who responded dramatically to permanent HBP.

      Abstract: Amiodarone is associated with a number of significant adverse effects, including elevated transaminase levels, pulmonary fibrosis, arrhythmia, and thyroid dysfunction. Although thyroid dysfunction is considered to be a common and potentially serious adverse effect of amiodarone therapy, the exact pathogenesis remains unknown because of its complex manifestations. Therefore, the prevalence of, and risk factors for, amiodarone-induced thyroid dysfunction in Japanese patients were investigated in the present study.

  • Temporal sinus node modification by high-dose continuous intravenous
           administration of landiolol in a patient with persistent inappropriate
           sinus tachycardia

    • Authors: Yuichi Hori; Shiro Nakahara, Naofumi Anjo, Yoshihiko Sakai, Isao Taguchi
      Abstract: A 20-year-old woman underwent an electrophysiological study for drug-resistant persistent inappropriate sinus tachycardia (IST). Use of a high-dose continuous intravenous administration of landiolol, a short-acting beta-adrenoreceptor blocker, made the patient׳s heart rate suddenly drop with a slight change in the P-wave morphology. Three-dimensional right atrial (RA) activation mapping revealed that the earliest activation site moved 8mm to a lower anterior site around the high lateral RA. Radiofrequency energy applied to the earliest activation site during tachycardia was successful.

  • Atriofascicular pathway detection with novel ablation catheter

    • Authors: Padmanabhan Shakkottai; Adrian Baranchuk, Neil Hobson, Jane Caldwell
      Abstract: Atriofascicular pathways are a rare cause of antidromic atrioventricular reciprocating tachycardia. The IntellaTip MiFi ablation catheter (Boston Scientific, MA, USA) is a novel ablation catheter that allows enhanced signal clarity with highly localized electrograms. This is the first report of this catheter being successfully used to map and ablate the atriofascicular pathway potentials.

    • Authors: Yasuhiro Yoshiga; Akihiko Shimizu, Takeshi Ueyama, Makoto Ono, Tomoko Fumimoto, Hironori Ishiguchi, Masafumi Yano
      Abstract: A 79-year-old man with situs inversus and dextrocardia underwent catheter ablation of symptomatic paroxysmal atrial fibrillation. Pulmonary vein isolation (PVI), using second-generation cryoballoon under Ensite NavX system guidance, was performed successfully in a reverse manner, which required short procedure and fluoroscopy times, as required in a PVI performed on a normal heart without any complications. Cryoballoon-based PVI under Ensite NavX guidance was feasible and safe to achieve a favorable outcome in this patient with abnormal anatomy.

  • Catheter ablation of anteroseptal accessory pathways from the aortic
           cusps: A case series and a review of the literature

    • Authors: Konstantinos P. Letsas; Michael Efremidis, Konstantinos Vlachos, Stamatis Georgopoulos, Nikolaos Karamichalakis, Athanasios Saplaouras, Sotirios Xydonas, Kosmas Valkanas, Antonios Sideris
      Abstract: Data regarding catheter ablation of anteroseptal accessory pathways through the aortic cusps are limited. We describe two cases of true para-Hisian accessory pathways successfully ablated from the aortic cusps (right coronary cusp and non-coronary cusp, respectively) along with a review of the current literature. Due to the close proximity to the atrioventricular node and the high risk of complication, mapping of the aortic cusps should always be considered in the case of anteroseptal accessory pathways.

  • Is it truly atrial tachycardia'

    • Authors: Yoshiaki Kaneko; Fumio Suzuki
      Abstract: We read the article by Okumura et al. [1] with great interest. The authors reported an ablation strategy applying manifest entrainment to treat adenosine triphosphate (ATP)-sensitive atrial tachycardia (AT) originating from the perinodal region. However, we have some concerns regarding the electrophysiological diagnosis of the tachycardia. The exclusion of atrioventricular nodal reentrant tachycardia (AVNRT) is essentially a prerequisite to diagnose AT. The authors excluded AVNRT based on the findings of atrioventricular dissociation during the ventricular pacing of tachycardia and a V–A–A–V activation sequence on ventricular induction of tachycardia.

  • Cardiac dynamics: Alternans and arrhythmogenesis

    • Authors: Gary Tse; Sheung Ting Wong, Vivian Tse, Yee Ting Lee, Hiu Yu Lin, Jie Ming Yeo
      Abstract: Pre-existing heterogeneities present in cardiac tissue are essential for maintaining the normal electrical and mechanical functions of the heart. Exacerbation of such heterogeneities or the emergence of dynamic factors can produce repolarization alternans, which are beat-to-beat alternations in the action potential time course. Traditionally, this was explained by restitution, but additional factors, such as cardiac memory, calcium handling dynamics, refractory period restitution, and mechano-electric feedback, are increasingly recognized as the underlying causes.

  • New horizon for infection prevention technology and implantable device

    • Authors: Yusuke Kondo; Marehiko Ueda, Yoshio Kobayashi, Joerg O. Schwab
      Abstract: There has been a significant increase in the number of patients receiving cardiovascular implantable electronic devices (CIED) over the last two decades. CIED infection represents a serious complication after CIED implantation and is associated with significant morbidity and mortality. Recently, newly advanced technologies have offered attractive and suitable therapeutic alternatives. Notably, the leadless pacemaker and anti-bacterial envelope decrease the potential risk of CIED infection and the resulting mortality, when it does occur.

           syndrome: A registry-based study

    • Authors: Charlotte Burns; Jodie Ingles, Andrew M. Davis, Vanessa Connell, Belinda Gray, Lauren Hunt, Julie McGaughran, Christopher Semsarian
      Abstract: Familial long QT syndrome (LQTS) is a primary arrhythmogenic disorder caused by mutations in ion channel genes. The phenotype ranges from asymptomatic individuals to sudden cardiac arrest and death. LQTS is a rare but significant health problem for which global data should exist. This study sought to provide the first clinical and genetic description of Australian families with LQTS.

  • The genetic background of arrhythmogenic right ventricular cardiomyopathy

    • Authors: Seiko Ohno
      Abstract: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is characterized by degeneration of the right ventricle and ventricular tachycardia originating from the right ventricle. Additionally, the disease is an inherited cardiomyopathy that mainly follows the autosomal dominant pattern. More than 10 genes have been reported as causative genes for ARVC, and more than half of ARVC patients carry mutations in desmosome related genes. The desmosome is one of the structures involved in cell adhesion and its disruption leads to various diseases, including a skin disease called pemphigus.

  • Atrial arrhythmias in inherited arrhythmogenic disorders

    • Authors: Can Hasdemir
      Abstract: Atrial arrhythmias are being increasingly recognized in inherited arrhythmogenic disorders particularly in patients with Brugada syndrome and short QT syndrome. Atrial arrhythmias in inherited arrhythmogenic disorders have significant epidemiologic, clinical, and prognostic implications. There has been progress in the understanding of underlying genetic characteristics and the mechanistic link between atrial arrhythmias and inherited arrhythmogenic disorders. Appropriate management of these patients is of paramount importance.

  • Recent advances in genetic testing and counseling for inherited
           arrhythmias

    • Authors: Yuka Mizusawa
      Abstract: Inherited arrhythmias, such as cardiomyopathies and cardiac ion channelopathies, along with coronary heart disease (CHD) are three most common disorders that predispose adults to sudden cardiac death. In the last three decades, causal genes in inherited arrhythmias have been successfully identified. At the same time, it has become evident that the genetic architectures are more complex than previously known. Recent advancements in DNA sequencing technology (next generation sequencing) have enabled us to study such complex genetic traits.

  • Molecular pathogenesis of long QT syndrome type 1

    • Authors: Jie Wu; Wei-Guang Ding, Minoru Horie
      Abstract: Long QT syndrome type 1 (LQT1) is a subtype of a congenital cardiac syndrome caused by mutation in the KCNQ1 gene, which encodes the α-subunit of the slow component of delayed rectifier K+ current (IKs) channel. Arrhythmias in LQT1 are characterized by prolongation of the QT interval on ECG, as well as the occurrence of life-threatening cardiac events, frequently triggered by adrenergic stimuli (e.g., physical or emotional stress). During the past two decades, much advancement has been made in understanding the molecular pathogenesis underlying LQT1.

  • Molecular pathogenesis of long QT syndrome type 2

    • Authors: Jennifer L. Smith; Corey L. Anderson, Don E. Burgess, Claude S. Elayi, Craig T. January, Brian P. Delisle
      Abstract: The molecular mechanisms underlying congenital long QT syndrome (LQTS) are now beginning to be understood. New insights into the etiology and therapeutic strategies are emerging from heterologous expression studies of LQTS-linked mutant proteins, as well as inducible pluripotent stem cell derived cardiomyocytes (iPSC-CMs) from LQTS patients. This review focuses on the major molecular mechanism that underlies LQTS type 2 (LQT2). LQT2 is caused by loss of function (LOF) mutations in KCNH2 (also known as the human Ether-à-go-go-Related Gene or hERG).
