  • Extracardiac compression of the inferolateral branch of the coronary vein
           by the descending aorta in a patient with dilated cardiomyopathy

    • Authors: Hiroki Konishi; Shumpei Mori, Tatsuya Nishii, Yu Izawa, Naoki Tamada, Hidekazu Tanaka, Kunihiko Kiuchi, Koji Fukuzawa, Ken-ichi Hirata
      Abstract: Extracardiac structures can cause distortion of cardiac anatomy particularly in patients presenting with a significantly dilated heart, and/or thoracic deformities. We present the case of a 69-year-old woman with dilated cardiomyopathy who underwent cardiac resynchronization therapy. Preoperative electrocardiography-gated contrast-enhanced computed tomography revealed the inferolateral wall of her significantly dilated and leftward-rotated heart was close to the descending aorta, and the descending aorta compressed the sandwiched inferolateral branch of the coronary vein.

  • Syncope in patients with inherited arrhythmias

    • Authors: Yukiko Nakano; Shimizu Wataru
      Abstract: Syncope, a common symptom of cerebral ischemia often shows a multifactorial etiopathogenesis. Although inherited arrhythmias causing syncope is uncommon, such an occurrence could be a warning sign preceding cardiac arrest. Long QT syndrome (LQTS) is a typical inherited arrhythmia causing syncope in children. Early diagnosis and treatment of LQTS using beta-blockers prevents recurrent syncope in LQTS. Brugada syndrome, another typical inherited arrhythmia causes syncope or sudden cardiac arrest in young individuals.

  • Complex regional pain syndrome induced by pacemaker implantation for sick
           sinus syndrome

    • Authors: Megumi Kisanuki; Kazumasa Fujita, Shohei Moriyama, Kei Irie, Chiharu Yosida, Mitsuhiro Fukata, Takeshi Arita, Taku Yokoyama, Keita Odashiro, Toru Maruyama, Koichi Akashi
      Abstract: A 53-year-old woman reported burning pain, muscle weakness, and dysesthesia of the left arm 2 months after permanent pacemaker insertion in the ipsilateral side for the treatment of sick sinus syndrome. Complex regional pain syndrome (CRPS) induced by pacemaker implantation was diagnosed. In 2017, her pulse generator became exhausted and was exchanged carefully to avoid exacerbation of CRPS, under the application of local anesthesia and premedication. Six months later, the patient's grip strength in her left hand remained lower relative to that in her right hand.

  • Radiofrequency ablation of ventricular premature contraction originating
           from a native coronary cusp after transcatheter aortic valve replacement

    • Authors: Shota Tohoku; Kenichi Hiroshima, Shoichi Kuramitsu, Michio Nagashima, Masato Fukunaga, Yoshimori An, Kenji Ando
      Abstract: We describe a case of radiofrequency ablation of ventricular premature contraction (VPC) originating from the left ventricular outflow tract after transcatheter aortic valve replacement. The VPC origin was the native aortic valve annulus between the left and right coronary cusps. Radiofrequency ablation was successfully performed by manipulating the ablation catheter from the gap between the sinotubular junction and implanted valve.

           ablation for atrial fibrillation

    • Authors: Michael Spartalis; Eleni Tzatzaki, MD, PhD, Nikolaos I. Nikiteas, MD, MSc, PhD, Eleftherios Spartalis, MD, MSc, PhD
      Abstract: We read with great interest the article by Murakawa et al. [1] titled, “Report of periprocedural oral anticoagulants in catheter ablation for atrial fibrillation: The Japanese Catheter Ablation Registry of Atrial Fibrillation (J-CARAF).” The authors concluded that the choice of a novel oral anticoagulant (NOAC) as a periprocedural anticoagulant did not significantly alter the incidence of serious complications, compared with uninterrupted warfarin. However, is this true'

      Abstract: Dabigatran is a direct thrombin inhibitor used to decrease the risk of ischemic stroke in patients with non-valvular atrial fibrillation (NVAF). Its prodrug, dabigatran etexilate (DE) is often co-administrated with a proton pump inhibitor (PPI) because of its adverse effects on the gastrointestinal tract. Drug-drug interactions between DE and PPIs in daily clinical practice have not been fully elucidated.

  • Cardiac resynchronization therapy via transvenous approach in a 2-year-old
           boy with a complete atrioventricular block after a tetralogy of Fallot
           repair

    • Authors: Hisaaki Aoki; Misugi Emi, Noboru Inamura, Shigemitsu Iwai, Futoshi Kayatani
      Abstract: Cardiac resychronization therapy (CRT) was performed via transvenous approach in a 2-year-old boy with a tetralogy of Fallot and postoperative severe heart failure, and complete atrioventricular block treated with a dual-chamber pacemaker. Epicardial leads were unavailable because of mediastinitis and the presence of severe bilateral pleural effusions requiring continuous drainage. There were no procedural complications. Biventricular pacing was significantly effective and both mediastinitis and pleural effusions recurred.

  • Transesophageal echocardiographic thromboembolic risk is associated with
           smoking status in patients with atrial fibrillation

    • Authors: Kyoko Inao; Tadakazu Hirai, Keiko Nakagawa, Satoshi Numa, Kazumasa Ohara, Nobuyuki Fukuda, Koichiro Kinugawa, Hiroshi Inoue
      Abstract: Smoking is a risk factor for cardiovascular diseases, but it is unclear whether smoking status, including environmental tobacco smoke, increases stroke risk in patients with atrial fibrillation (AF). Abnormalities of the left atrium (LA) and aortic atherosclerosis, as detected by transesophageal echocardiography (TEE), are risk factors for stroke and thromboembolism in AF patients. We investigated the impact of smoking status on thromboembolic risk by TEE in patients with nonvalvular AF.

      Abstract: A 74-year-old woman who developed atrial tachycardia following the Cox-Maze IV procedure underwent catheter ablation. The reentrant circuit included the coronary sinus (CS), Marshall bundle (MB), distal MB-left atrial (LA) connection, and anterolateral mitral annulus. The distal MB-LA connection was the last barrier in the conduction pathway between the CS and the left atrium.

  • Ventricular arrhythmias in non-ischemic cardiomyopathy

      Abstract: Non-ischemic cardiomyopathies (NICMs) are composed of variable disease entities, including primary and secondary cardiomyopathies. Determining the etiology of NICM provides pivotal roles of not only the understanding of the individual pathogenesis, but also the clinical management, such as risk stratification, pharmacological treatment, and intervention therapies. Despite the diverse causes of NICM, these cases mostly require clinical attention owing to progressive myocardial injury, resulting in ventricular dysfunction and heart failure.

  • Role of head-up tilt table testing in patients with syncope or transient
           loss of consciousness

    • Authors: Toshiyuki Furukawa
      Abstract: The tilt table test (TTT) is a useful method for the management of reflex syncope. However, the TTT is incomplete and has several problems. The indications for this test are established using guidelines. The TTT is not suitable for all syncopal patients. It is currently unclear (1) When should the TTT be used, (2) for which types of patients TTT should be performed, and (3) does the TTT provide useful information to guide indication for pacing therapy for reflex syncope. The answers to these questions appear in recent reports from two guidelines published by the European Society of Cardiology and the Japan Circulation Society.

  • The details of an unusual “ghost” after transvenous lead extraction:
           Three-dimensional computed tomography analysis

    • Authors: Kunihiko Kiuchi; Koji Fukuzawa, Shumpei Mori, Tatsuya Nishii, Kensuke Matsumoto, Hirotoshi Ichibori, Takashi Yamada
      Abstract: Transvenous lead extraction (TLE) is performed to prevent deaths in patients with device infections. Intracardiac masses detected by echocardiography, i.e., “ghosts,” are reported in 8% of patients after a TLE in retrospective studies and in 14% in prospective studies. We herein describe a case with unusual ghosts after a TLE. Three-dimensional computed tomography (3DCT) is useful for revealing all the details of unusual ghosts. In this case, the residual silicone insulation and “cast,” including the fibrous sheath and severe calcifications could be visualized and differentiated by 3DCT.

  • Ventricular arrhythmias in patients with Takotsubo syndrome

    • Authors: Christian Möller; Charlotte Eitel, Holger Thiele, Ingo Eitel, Thomas Stiermaier
      Abstract: Takotsubo syndrome (TTS) is a unique non-ischemic cardiac disease characterized by acute myocardial dysfunction of the left and/or right ventricle. Patients are predominantly postmenopausal women and usually present with symptoms indistinguishable from acute coronary syndrome. Although the exact pathomechanisms of TTS remain elusive, increasing evidence suggests that sympathetic overdrive and catecholamine excess might play a central role. Despite complete recovery of ventricular dysfunction within several days to weeks, TTS patients exhibit considerable short- and long-term mortality rates and ventricular arrhythmias have been identified as key contributor to morbidity and mortality.

  • Syncope and the risk of sudden cardiac death: Evaluation, management, and
           prevention

    • Authors: Ryan J. Koene; Wayne O. Adkisson, David G. Benditt
      Abstract: Syncope is a clinical syndrome defined as a relatively brief self-limited transient loss of consciousness (TLOC) caused by a period of inadequate cerebral nutrient flow. Most often the trigger is an abrupt drop of systemic blood pressure. True syncope must be distinguished from other common non-syncope conditions in which real or apparent TLOC may occur such as seizures, concussions, or accidental falls. The causes of syncope are diverse, but in most instances, are relatively benign (e.g., reflex and orthostatic faints) with the main risks being accidents and/or injury.

  • Ambulatory electrocardiogram monitoring devices for evaluating transient
           loss of consciousness or other related symptoms

    • Authors: Ritsuko Kohno; Haruhiko Abe, David G. Benditt
      Abstract: Capturing electrocardiograms (ECGs) during spontaneous events is the most powerful available tool to identify or exclude an arrhythmic cause of symptoms, and often can elucidate the definite diagnosis for different conditions, such as transient loss of consciousness (T-LOC), lightheadedness, or palpitations. Current ambulatory ECG monitoring technologies include 24-hour Holter, wearable event recorder, external loop recorder (ELR), and insertable cardiac monitoring (ICM). Of them, Holter ECG is most frequently used in daily practice in Japan, while ELR and ICM are less frequently used.

  • Driving restrictions for patients with reflex syncope

    • Authors: Masataka Sumiyoshi
      Abstract: Reflex syncope is the most common form of syncope that occurs while driving. The 2014 revision of Japanese Road Traffic Laws placed stricter driving restrictions, along with some associated legal penalties, on individuals with recurrent syncope. “Recurrent syncope” is defined as the occurrence of more than two episodes of syncope over a period of 5 years. No restrictions are recommended for private drivers unless they experience syncope without a reliable prodrome while driving or sitting. For commercial drivers, a driving restriction is recommended unless the efficacy of treatment can be confirmed.

  • Reflex syncope: Diagnosis and treatment

    • Authors: Richard Sutton
      Abstract: For the diagnosis of reflex syncope, diligent history-building with the patient and a witness is required. In the Emergency Department (ED), the assessment of syncope is a challenge which may be addressed by an ED Observation Unit or by a referral to a Syncope Unit. Hospital admission is necessary for those with life-threatening cardiac conditions although risk stratification remains an unsolved problem. Other patients may be investigated with less urgency by carotid sinus massage (>40 years), tilt testing, and electrocardiogram loop recorder insertion resulting in a clear cause for syncope.

  • Use of implantable and external loop recorders in syncope with unknown
           causes

    • Authors: Kaoru Tanno
      Abstract: The gold standard for diagnosing syncope is to elucidate the symptom-electrocardiogram (ECG) correlation. The ECG recordings during syncope allow physicians to either confirm or exclude an arrhythmia as the mechanism of syncope. Many studies have investigated the use of internal loop recorder (ILR), while few studies have used external loop recorder (ELR) for patients with unexplained syncope. The aim of this review is to clarify the clinical usefulness of ILR and ELR in the diagnosis and management of patients with unexplained syncope.

  • Life-threatening arrhythmias leading to syncope in patients with
           vasospastic angina

    • Authors: Mitsuhiro Nishizaki
      Abstract: The coronary artery diseases (CAD) that can lead to the occurrence of a syncopal attack include acute coronary syndrome, vasospastic angina, effort angina, and prior myocardial infarction. The possible mechanisms considered to lead to syncope in patients with CAD are pump failure, tachyarrhythmia, bradycardia, and vagal stimulation. Coronary artery spasm, in particular, is occasionally observed in patients with unexplained syncope in Japan. Life-threatening arrhythmias are among the most serious complications of an ischemic attack caused by coronary spasm, and are associated with an increased risk of syncope and/or sudden cardiac death (SCD).

  • Syncope and paroxysmal atrioventricular block

    • Authors: Milena Aste; Michele Brignole
      Abstract: Current literature reveals three types of paroxysmal atrioventricular block (AVB) that can cause syncope:Intrinsic paroxysmal atrioventricular block is due to an intrinsic disease of the AV conduction system; this type of “cardiac syncope” is also called Stokes-Adams attack;Extrinsic vagal paroxysmal atrioventricular block is linked to the effect of the parasympathetic nervous system on cardiac conduction and is one of the mechanisms involved in “reflex syncope.”Extrinsic idiopathic paroxysmal atrioventricular block is associated with low levels of endogenous adenosine and is supposed to be one of the mechanisms involved in “low-adenosine syncope.”These three types of paroxysmal AVB present different clinical and electrocardiographic features.

  • Driving restrictions in patients with implantable cardioverter
           defibrillators and pacemakers

    • Authors: Eiichi Watanabe; Haruhiko Abe, Shigeyuki Watanabe
      Abstract: Implantable cardioverter-defibrillators (ICDs) improve the survival in patients at risk of sudden cardiac death. However, these patients have an ongoing risk of sudden incapacitation that may cause harm to individuals and others when driving. Considerable disagreement exists about whether and when these patients should be allowed to resume driving after ICD therapies. This information is critical for the management decisions to avoid future potentially lethal incidents and unnecessary restrictions for ICD patients.

      First page: 410
      Abstract: Cardiac resynchronization therapy (CRT) using a biventricular pacing system has been an effective therapeutic strategy in patients with symptomatic heart failure with a reduced left ventricular ejection fraction (LVEF) of 35% or less and a QRS duration of 130ms or more. The etiology of heart failure can be classified as either ischemic or non-ischemic cardiomyopathy. Ischemic etiology of patients receiving CRT is prevalent predominantly in North America, moderately in Europe, and less so in Japan.

      Abstract: Cardiac resynchronization therapy (CRT) improves both morbidity and mortality in selected patients with heart failure and increased QRS duration. However, chronic kidney disease (CKD) may have an adverse effect on patient outcome. The aim of this systematic review was to analyze the existing data regarding the impact of baseline renal function on all-cause mortality in patients who underwent CRT.

  • Intracoronary acetylcholine application as a possible probe inducing J
           waves in patients with early repolarization syndrome

    • Authors: Toru Maruyama; Kazumasa Fujita, Kei Irie, Shouhei Moriyama, Mitsuhiro Fukata
      First page: 424
      Abstract: Acetylcholine is widely used for a diagnostic provocation test of coronary spasm in patients with vasospastic angina. Acetylcholine usually induces coronary vasodilatation mediated by muscarinic receptor activation, but sometimes it evokes vasoconstriction of coronary arteries where the endothelium is damaged. Early repolarization syndrome is characterized by a J wave observed at the end of the QRS complex in a surface electrocardiogram. The J wave is attributed to the transmural voltage gradient at the early repolarization phase across the ventricular wall, which stems mainly from prominent transient outward current in the epicardium, but not in the endocardium.

      Abstract: The periprocedural protocol for atrial fibrillation (AF) ablation commonly includes anticoagulation therapy. Apixaban, a direct oral anticoagulant, is currently approved for clinical use; however, little is known about the effects of residual apixaban concentration on bleeding complications during/after AF ablation. Therefore, we measured residual apixaban concentration by using mass spectrometry and examined the anticoagulant's residual effects on bleeding complications.

      Abstract: Catheter ablation of premature ventricular complexes (PVCs) has been used as a curative therapy in many cases. Intracardiac ultrasound with a magnetic sensor probe has recently become available for catheter ablation. In this study, we assessed a new mapping method, contraction mapping, for determining the optimal ablation sites using intracardiac ultrasound and M-mode. This study sought to assess the accuracy of the new mapping method using intracardiac echocardiography.

      Abstract: In patients with left ventricular assist device (LVAD), a minority of post-operative ventricular tachycardias (VTs) is caused by contact between the inflow cannula and the endocardium. Currently, electrophysiologic characteristics and pathologic features of this condition are lacking. We report on a case of a successfully ablated mechanical VT. After VT recurrence, heart transplantation took place. Pathologic observations were consistent with direct tissue injury and inflammation, eventually contributing to persisting arrhythmias.

      Abstract: A seventy year-old male was referred to our hospital to undergo radiofrequency catheter ablation (RFCA) for drug-refractory paroxysmal atrial fibrillation (AF). Pre-operative three-dimensional computed tomography revealed a unique left atrial (LA) roof vein. Electrophysiological findings showed expansion of the myocardial sleeve and local firing in the LA roof vein. We performed isolation of this arrhythmogenic abnormal vein concomitant with general pulmonary vein isolation in this case, and AF did not recur after the procedure.

      Abstract: A 76-year-old man who had been diagnosed with long-QT syndrome type 2 had frequent syncopal attacks. The electrocardiogram was monitored, and frequent torsades de pointes (TdP) was detected despite administration of conventional medications: oral propranolol, verapamil, intravenous magnesium sulfate, verapamil, and lidocaine. In contrast, 2μg/kg/min landiolol could completely suppress TdP. Subsequently, an implantable cardioverter defibrillator was placed, and he was diagnosed with silent myocardial ischemia using myocardial perfusion scintigraphy and coronary angiography.

      Abstract: Herein, we report a 47-year-old woman with ischemic cardiomyopathy who underwent ablation therapy due to an electrical storm without any triggers. The voltage mapping in sinus rhythm with the Rhythmia system and Orion catheter displayed several LAVAs in and around the anteroapical scar area. Although the patient did not tolerate the induced clinical ventricular tachycardia, which was reproductively induced, 35-second-mapping in the scar zone with the Orion catheter demonstrated the VT circuit with the critical isthmus.

      Abstract: We report a case of a 7-year-old girl with atriofascicular Mahaim (AFM) pathway concomitant with Ebstein's anomaly. The QRS wave showed left bundle branch block pattern on electrocardiogram. Holter electrocardiogram showed prolongation of the PR interval and QRS morphological change during sinus tachycardia. An electrophysiological study demonstrated that the distal His potential appeared earlier than the proximal His potential, which suggested retrograde His conduction toward the atrioventricular node.

      Abstract: Pulmonary vein isolation is an effective treatment for patients with atrial fibrillation (AF).Although vasospastic angina (VSA) is not a common complication after ablation of AF, we report 3 cases of VSA following ablation of persistent AF. Two of the 3 patients felt chest pain following pulmonary vein isolation, and complex fractionated atrial electrogram ablations were performed. ST elevation in the inferior leads and atrioventricular block occurred because of severe coronary vasospasm. In the third patient, the electrocardiography monitor detected transient ST elevation within an hour after ablation.

      Abstract: We report the case of a man in his 60s who had dilated cardiomyopathy with severe functional mitral regurgitation. Four years after a cardiac resynchronization therapy (CRT) device with an implantable cardioverter defibrillator was implanted, this device was replaced with an adaptive CRT device because of battery consumption. Seven months after replacement of this device, the left ventricular pacing to right ventricular activation and the atrioventricular delay from automatic adjustments contributed to less functional mitral regurgitation.

      Abstract: I have read with great interest the case report entitled “Epicardially placed implantable cardioverter-defibrillator for a child with congenital long QT syndrome” by Sugiyama et al. in the latest issue of the journal [1]. The authors well presented a case of long QT syndrome managed using implantation of an epicardial shock electrode and dose titration of beta-blocker therapy. However, some important issues should be mentioned. As compared to beta-blocker therapy with metoprolol, treatment with nadolol has been shown to significantly decrease breakthrough cardiac events in symptomatic patients [2].
