  • Risk factors for amiodarone-induced thyroid dysfunction in Japan

    • Authors: Sayoko Kinoshita; Tomohiro Hayashi, Kyoichi Wada, Mikie Yamato, Takeshi Kuwahara, Toshihisa Anzai, Mai Fujimoto, Kouichi Hosomi, Mitsutaka Takada
      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.

  • Successful cryoballoon pulmonary vein isolation in a patient with situs
           inversus and dextrocardia

    • 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.

  • Double twiddle trouble, a new variant of twiddler syndrome

    • Authors: Aldo G. Carrizo; Paul S.G. Hong, Guy Amit, Jeff S. Healey
      Abstract: The twiddler syndrome results in retraction and coiling of the lead in the pacemaker pocket with subsequent pacemaker malfunction. If the lead׳s parameters are not affected, then the problem can be corrected by lead repositioning. We describe the first reported case of a dramatic pacemaker lead coiling with a double level of lead compromise, with one of them being intra-cardiac. This condition affected our treatment strategy, as the repositioning of the lead was unfeasible.

  • 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.

      Abstract: The majority of embolisms associated with atrial fibrillation (AF) are from the left atrial appendage (LAA). To treat the existing thrombus, warfarin and novel anticoagulants have been used. However, there has been no clinical information regarding the difference of the effects of congealing the fibrinogenolysis system among these oral anticoagulants. Here, we report a case of persistent AF, in whom apixaban, factor Xa inhibitor resolved an LAA clot refractory to warfarin and direct thrombin inhibition.

  • 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.

  • Eccentric scar formation around a pulmonary vein after cryo-balloon
           ablation in a patient with atrial fibrillation: A case report

    • Authors: Kunihiko Kiuchi; Koji Fukuzawa, Akinori Matsumoto
      Abstract: The impact of a cryoballoon ablation is reported to be similar to that of a radiofrequency (RF) ablation in patients with atrial fibrillation. Delayed enhancement magnetic resonance imaging (DE-MRI) could visualize the scar region induced by the cryoballoon ablation as well as RF ablation. Cryoballoon ablation could induce extensive scar lesions around the PVs. However, the distribution of the scar lesions after the cryoballoon ablation has not been well discussed. We, herein, described a case with an eccentric scar distribution after cryoballoon ablation.

           defibrillator: Single-center experience

    • Abstract: The subcutaneous implantable cardioverter defibrillator (S-ICD) is a novel device now accepted in clinical practice for treating ventricular arrhythmias. In 14 consecutive patients, S-ICD devices were placed in the virtual space between the anterior surface of the serratus anterior muscle and the posterior surface of the latissimus dorsi muscle. During a mean follow up of 9 months, no dislocations, infections, hematoma formations, or skin erosions were observed. Intermuscular implantation of the S-ICD could be a reliable, safe, and appealing alternative to the standard subcutaneous placement.

  • 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.

      Abstract: Placement of an implantable cardioverter–defibrillator (ICD) is the only powerful treatment modality for Brugada syndrome in patients presenting with ventricular fibrillation (VF). For those whose first presentation is an electrical storm, pharmacologic therapy is typically used to control VF followed by ICD implantation. We report an alternative approach whereby, before ICD implantation, emergency catheter ablation of the VF-triggering premature ventricular contraction (PVC) resulted in long-term VF-free survival.

           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.

    • Authors: Akira Mizukami; Makoto Suzuki, Rena Nakamura, Shunsuke Kuroda, Maki Ono, Yuya Matsue, Ryota Iwatsuka, Taishi Yonetsu, Akihiko Matsumura, Yuji Hashimoto
      Abstract: A 26-year-old woman in her first pregnancy presented with persistent atrial tachycardia (AT). AT was resistant to medications, cardioversions, and the first attempt of catheter ablation. Two months after delivery she developed severe systolic dysfunction and circulatory collapse. Emergent catheter ablation was performed with the support of percutaneous cardiopulmonary bypass and intraaortic balloon pump. The AT originated in the apex of the right atrial appendage (RAA). Repeated attempts at ablation were unsuccessful, prompting surgical RAA resection, which terminated the tachycardia and improved the cardiac function.

  • 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.

  • Home monitoring report from a single lead Lumax DX implantable
           cardioverter defibrillator: New observations in a new system

    • Authors: Yuval Konstantino; Alex Kleiman, Guy Amit
      Abstract: A 56-year-old man underwent a single lead Lumax 640 DX implantable cardioverter defibrillator implantation for primary prevention of sudden cardiac death. A DX system consists of a single lead, which provides atrial as well as ventricular electrograms, and enhances atrial arrhythmia detection. Three months after the implantation, high-frequency episodes were detected on the far field and the atrial channels, but not on the bipolar right ventricular channel; these were classified as atrial tachycardia.

  • 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).

  • Management of antithrombotic therapy during cardiac implantable device
           surgery

    • Authors: Ahmed AlTurki; Riccardo Proietti, David H. Birnie, Vidal Essebag
      Abstract: Anticoagulants are commonly used drugs that are frequently encountered during device placement. Deciding when to halt or continue the use of anticoagulants is a balance between the risks of thromboembolism versus bleeding. Patients taking warfarin with a high risk of thromboembolism should continue to take their warfarin without interruption during device placement while ensuring their international normalized ratio remains below 3. For patients who are taking warfarin and have low risk of thromboembolism, either interrupted or continued warfarin may be used, with no evidence to clearly support either strategy.

      Abstract: The human ether-a-go-go-related gene (HERG) encodes the α-subunit of rapidly activating delayed-rectifier potassium channels. Mutations in this gene cause long QT syndrome type 2 (LQT2). In most cases, mutations reduce the stability of the channel protein, which can be restored by heat shock (HS).

  • Current topics in catecholaminergic polymorphic ventricular tachycardia

    • Authors: Naokata Sumitomo
      Abstract: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is induced by emotions or exercise in patients without organic heart disease and may be polymorphic or bidirectional in nature. The prognosis of CPVT is not good, and therefore prevention of sudden death is of utmost importance. Genetic variants of CPVT include RyR2, CASQ2, CALM2, TRD, and possibly KCNJ2 and ANK2 gene mutations. Hypotheses that suggest the causes of CPVT include weakened binding of FKBP12.6 and RyR2, a store overload-induced Ca2+ release (SOICR), unzipping of intramolecular domain interactions in RyR2, and molecular and functional abnormalities caused by mutations in the CASQ2 gene.

  • Conservative therapy for the management of cardiac implantable electronic
           device infection

    • Authors: Yukio Sekiguchi
      Abstract: Along with the increased frequency of implantation, the incidence of cardiac implantable electronic device (CIED) infection, which can have serious or fatal complications, has also increased. Although several successful conservative therapies for CIED infection have been reported, retained infected devices remain a source of relapse, which is closely related to a higher mortality rate. Presently, complete hardware removal is initially recommended for infected CIED patients, and indications for conservative therapy, including continuous administration of antibiotics, require careful consideration.

  • Molecular autopsy in victims of inherited arrhythmias

    • Authors: Christopher Semsarian; Jodie Ingles
      Abstract: Sudden cardiac death (SCD) is a rare but devastating complication of a number of underlying cardiovascular diseases. While coronary artery disease and acute myocardial infarction are the most common causes of SCD in older populations, inherited cardiac disorders comprise a substantial proportion of SCD cases aged less than 40 years. Inherited cardiac disorders include primary inherited arrhythmogenic disorders such as familial long QT syndrome (LQTS), Brugada syndrome (BrS), catecholaminergic polymorphic ventricular tachycardia (CPVT), and inherited cardiomyopathies, most commonly hypertrophic cardiomyopathy (HCM).

  • Inherited bradyarrhythmia: A diverse genetic background

    • Authors: Taisuke Ishikawa; Yukiomi Tsuji, Naomasa Makita
      Abstract: Bradyarrhythmia is a common heart rhythm abnormality comprising number of diseases and is associated with decreased heart rate due to the failure of action potential generation and propagation at the sinus node. Permanent pacemaker implantation is often used therapeutically to compensate for decreased heart rate and cardiac output. The vast majority of bradyarrhythmia cases are attributable either to aging or to structural abnormalities of the cardiac conduction system, caused by underlying structural heart disease.

  • Left cardiac sympathetic denervation: An important treatment option for
           patients with hereditary ventricular arrhythmias

    • Authors: Yongkeun Cho
      Abstract: Medications such as ß-blockers are currently the primary treatment for patients with hereditary arrhythmia syndromes such as long QT syndrome (LQTS) and catecholaminergic polymorphic ventricular tachycardia (CPVT). However, these drugs are ineffective in some patients, and the other treatment option, that is implantable cardioverter defibrillator (ICD) implantation, is associated with significant complications in young and active patients. Left cardiac sympathetic denervation (LCSD) may reduce the wide gap between life-long ß-blocker medication and ICD implantation.

  • Arrhythmia management after device removal

    • Authors: Nobuhiro Nishii
      Abstract: Arrhythmic management is needed after removal of cardiac implantable electronic devices (CIEDs). Patients completely dependent on CIEDs need temporary device back-up until new CIEDs are implanted. Various methods are available for device back-up, and the appropriate management varies among patients. The duration from CIED removal to implantation of a new CIED also differs among patients. Temporary pacing is needed for patients with bradycardia, a wearable cardioverter defibrillator (WCD) or catheter ablation is needed for patients with tachyarrhythmia, and sequential pacing is needed for patients dependent on cardiac resynchronization therapy.

      Abstract: Transvenous lead extraction is becoming popular in Japan since the approval of laser extraction system in 2010. The laser system seems to be the standard method used by most physicians, owing to its efficacy and ease of handling. The efficacy and safety of this technology has been well proven in many studies and the data suggest that it can be used for Japanese patients safely. However, lead extraction can cause serious complications. Thus, it is important to learn the limitations as well as the basic techniques and efficacy of this procedure.

    • Authors: Katsuhiko Imai
      Abstract: Cardiac implantable electronic devices (CIEDs) have become important in the treatment of cardiac disease and placement rates increased significantly in the last decade. However, despite the use of appropriate antimicrobial prophylaxis, CIED infection rates are increasing disproportionately to the implantation rate. CIED infection often requires explantation of all hardware, and at times results in death. Surgical site infection (SSI) is the most common cause of CIED infection as a pocket infection.

  • Mechanisms of cardiac arrhythmias

    • Authors: Gary Tse
      First page: 75
      Abstract: Blood circulation is the result of the beating of the heart, which provides the mechanical force to pump oxygenated blood to, and deoxygenated blood away from, the peripheral tissues. This depends critically on the preceding electrical activation. Disruptions in the orderly pattern of this propagating cardiac excitation wave can lead to arrhythmias. Understanding of the mechanisms underlying their generation and maintenance requires knowledge of the ionic contributions to the cardiac action potential, which is discussed in the first part of this review.

      Abstract: There are no criteria for selecting single- or dual-chamber implantable cardioverter defibrillators (ICDs) in patients without a pacing indication. Recent reports showed no benefit of the dual-chamber system despite its preference in the United States. As data on ICD selection and respective outcomes in Japanese patients are scarce, we investigated trends regarding single- and dual-chamber ICD usage in Japan.

      Abstract: An 85-year-old man was referred to our hospital with a pacemaker pocket infection. A permanent pacemaker had been implanted via the right subclavian vein. The pacemaker and pacing leads were removed and a temporary pacemaker was implanted. After vancomycin treatment for 4 weeks, pacemaker implantation via the right external iliac vein was performed under local anesthesia because of left subclavian vein occlusion, infection of the right pocket, and difficulty with epicardial lead insertion. The iliac vein approach is an effective alternative in patients in whom the pectoral approach cannot be used.

      First page: 157
      Abstract: A 57-year-old woman with a history of dizziness due to episodes of complete heart block and bradycardia was referred to the electrophysiology ward for pacemaker implantation. A dual chamber pacemaker (Medtronic, Relia, Medtronic, Minneapolis, USA) was implanted. Its analysis showed normal function (atrial lead capture threshold 0.5V at 0.4ms, ventricular lead capture threshold 0.75V at 0.4ms, and P-wave and R wave amplitude sensing 2mV and 8mV, respectively). The pacemaker was programmed in the DDDR mode with a lower rate limit of 60bpm, atrial and ventricular output of 3.5V and 3.5V at 0.4ms respectively, atrial and ventricular sensitivity of 0.5mV and 2.8mV respectively, a paced atrioventricular interval (pAVI) of 180ms, and a sensed atrioventricular interval of 150ms.

      Abstract: Acute pulmonary embolism (PE) is a frequent life-threatening condition in emergency departments. Careful diagnosis is important, and different diagnostic tests such as electrocardiogram (ECG), biochemical markers, echocardiogram, and computed tomography are required. Although ECG is a cheap and rapid diagnostic test for pulmonary embolism, it has some limitations in the differential diagnosis of acute coronary syndrome and acute PE. Herein, we report ECG results of a patient diagnosed with acute PE mimicking acute coronary syndrome.
