Junctional Tachycardia as a Diagnostic Criterion in Acute Rheumatic Fever.

Pediatrics 2021 May 5. Epub 2021 May 5.

Department of Pediatrics, John A. Burns School of Medicine, University of Hawaii, Honolulu, Hawaii; and.

Acute rheumatic fever (ARF) is an acute inflammatory process resulting in rheumatic carditis, one of the most common acquired heart diseases in youth. Among the clinical manifestations of carditis, pathologic valve regurgitation and atrioventricular block are included in the criteria for the diagnosis of ARF. Besides atrioventricular block, ARF may often present with other arrhythmias, such as junctional tachycardia (JT). Read More

Deconditioning does not explain orthostatic intolerance in ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome).

J Transl Med 2021 May 4;19(1):193. Epub 2021 May 4.

Stichting CardioZorg, Planetenweg 5, 2132 HN, Hoofddorp, Netherlands.

Background: Orthostatic intolerance (OI) is a frequent finding in individuals with myalgic encephalomyelitis /chronic fatigue syndrome (ME/CFS). Published studies have proposed that deconditioning is an important pathophysiological mechanism in various forms of OI, including postural orthostatic tachycardia syndrome (POTS), however conflicting opinions exist. Deconditioning can be classified objectively using the predicted peak oxygen consumption (VO) values from cardiopulmonary exercise testing (CPET). Read More

Aberrated supraventricular tachycardia associated with neonatal fever and COVID-19 infection.

BMJ Case Rep 2021 Apr 30;14(4). Epub 2021 Apr 30.

Division of Cardiology, Ann and Robert H Lurie Children's Hospital of Chicago, Chicago, Illinois, USA.

A 9-day-old girl presented during the 2020 SARS-CoV-2 pandemic in wide-complex tachycardia with acute, symptomatic COVID-19 infection. Because the potential cardiac complications of COVID-19 were unknown at the time of her presentation, we chose to avoid the potential risks of haemodynamic collapse associated with afterload reduction from adenosine. Instead, a transoesophageal pacing catheter was placed. Read More

Burst Exercise Testing Can Unmask Arrhythmias in Patients With Incompletely Penetrant Catecholaminergic Polymorphic Ventricular Tachycardia.

JACC Clin Electrophysiol 2021 Apr;7(4):437-441

Centre for Cardiovascular Innovation, Division of Cardiology, University of British Columbia, Vancouver, British Columbia, Canada. Electronic address:

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is characterized by cardiac arrest during sudden exertion. However, standard exercise stress testing (EST) lacks sensitivity, leading to misdiagnosis and undertreatment. After a nondiagnostic standard gradual EST, we report 6 patients who underwent a novel burst exercise test characterized by sudden high workload at the outset of testing. Read More

Impact of augmented-reality improvement in ablation catheter navigation as assessed by virtual-heart simulations of ventricular tachycardia ablation.

Comput Biol Med 2021 Apr 2;133:104366. Epub 2021 Apr 2.

Alliance for Cardiovascular Diagnostic and Treatment Innovation, Johns Hopkins University, Baltimore, MD, USA; Department of Biomedical Engineering, Johns Hopkins University, Baltimore, MD, USA.

Background: Recently, an augmented reality (AR) solution allows the physician to place the ablation catheter at the designated lesion site more accurately during cardiac electrophysiology studies. The improvement in navigation accuracy may positively affect ventricular tachycardia (VT) ablation termination, however assessment of this in the clinic would be difficult. Novel personalized virtual heart technology enables non-invasive identification of optimal lesion targets for infarct-related VT. Read More

Brain Dev 2021 Apr 4. Epub 2021 Apr 4.

Department of Pediatrics and Neonatology, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan.

Introduction: SCN8A-related epilepsy has various phenotypes. In particular, patients with developmental and epileptic encephalopathy (DEE) are resistant to antiepileptic drugs and may present with autonomic symptoms, such as marked bradycardia and apnea during seizures, and thus have an increased risk of sudden death. Herein, we report a case of very severe SCN8A-related epilepsy necessitating cardiac pacemaker implantation because of repetitive ictal asystole. Read More

Increased ROS-Mediated CaMKII Activation Contributes to Calcium Handling Abnormalities and Impaired Contraction in Barth Syndrome.

Circulation 2021 Apr 1. Epub 2021 Apr 1.

Department of Cardiology, Boston Children's Hospital, Boston, MA; Harvard Stem Cell Institute, Cambridge, MA.

Mutations in tafazzin (), a gene required for biogenesis of cardiolipin, the signature phospholipid of the inner mitochondrial membrane, causes Barth syndrome (BTHS). Cardiomyopathy and risk of sudden cardiac death are prominent features of BTHS, but the mechanisms by which impaired cardiolipin biogenesis causes cardiac muscle weakness and arrhythmia are poorly understood. We performed in vivo electrophysiology to define arrhythmia vulnerability in cardiac specific knockout mice. Read More

Heart Rhythm 2021 Mar 16. Epub 2021 Mar 16.

Division of Cardiology, Department of Medicine, University of California, San Diego, La Jolla, California.

Background: Studies have suggested that a fasciculoventricular pathway (FVP) may be the cause of preexcitation in patients with Danon disease, a rare X-linked dominant genetic disorder of hypertrophic cardiomyopathy.

Objective: The purpose of this study was to describe the prevalence of ventricular preexcitation on resting 12-lead electrocardiogram (ECG) in patients with Danon disease and the electrophysiological study (EPS) results of those with preexcitation.

Decreased Stroke Volume and Venous Return in School Children with Postural Tachycardia Syndrome.

Tohoku J Exp Med 2021 03;253(3):181-190

Department of Pediatrics and Child Health, Nihon University School of Medicine.

In postural tachycardia syndrome (POTS), a subtype of orthostatic intolerance, the changes in hemodynamics due to postural changes are poorly understood. We speculated that inappropriate venous return, which may occur in the upright position in patients with school-aged POTS, could be detected by echocardiography. Our prospective study was conducted with 100 POTS patients (45 boys and 55 girls), aged 13. Read More

The efficacy of catheter ablation versus ICD for prevention of ventricular tachycardia in patients with ischemic heart disease: a systematic review and meta-analysis.

J Interv Card Electrophysiol 2021 Mar 15. Epub 2021 Mar 15.

Department of Cardiology; Ministry of Education Key Laboratory of Child Development and Disorders; National Clinical Research Center for Child Health and Disorders; China International Science and Technology Cooperation base of Child development and Critical Disorders, Children's Hospital of Chongqing Medical University, Chongqing, 400014, China.

Purpose: Although implantable cardioverter defibrillator (ICD) could prevent the sudden death of ventricular tachycardia (VT) in patients with ischemic heart disease, it could not effectively prevent the recurrence of ventricular tachycardia. Several studies have suggested that catheter ablation may effectively decrease the incidence of ICD events, but relevant dates from randomized controlled trials were limited.

Methods: A systematic review and meta-analysis of randomized controlled trials were performed to evaluate the effect of catheter ablation for the prevention of VT in patients with ischemic heart disease. Read More
