BACKGROUND Catecholaminergic polymorphic ventricular tachycardia is an inherited arrhythmogenic disorder characterized by sudden cardiac death in children. Drug therapy is still insufficient to provide full protection against cardiac arrest, and the use of implantable defibrillators in the pediatric population is limited by side effects. There is therefore a need to explore the curative potenti...
BACKGROUND Left cardiac sympathetic denervation reduces risk in long-QT syndrome (LQTS) and catecholaminergic polymorphic ventricular tachycardia. Side effects and patient satisfaction have not been systematically analyzed in patients who underwent left cardiac sympathetic denervation. Aims of this study included documenting physical and psychological consequences and patient satisfaction after...
OBJECTIVE To emphasize the importance of ventricular tachycardia associated with repolarisation abnormality in syncope associated with exercise. DESIGN Retrospective analysis of data on children presenting with syncope between 1985 and 1993. PATIENTS 5 apparently normal children with recurrent exercise related syncope associated with electrocardiographically abnormal TU complexes. RESULTS...
BACKGROUND Catecholaminergic polymorphic ventricular tachycardia is an uncommon, potentially lethal, ion channelopathy. Standard therapies have high failure rates and little is known about treatment in children. Newer options such as flecainide and left cardiac sympathetic denervation are not well validated. We sought to define treatment outcomes in children with catecholaminergic polymorphic v...
OBJECTIVE To investigate the clinical outcome, ECG characteristics, and optimal treatment of catecholaminergic polymorphic ventricular tachycardia (CPVT), a malignant and rare ventricular tachycardia. PATIENTS AND METHODS Questionnaire responses and ECGs of 29 patients with CPVT were evaluated. Mean (SD) age of onset was 10.3 (6.1) years. RESULTS The initial CPVT manifestations were syncope...
APPLIED PHYSICAL SCIENCES, MEDICAL SCIENCES Correction for ‘‘Synchronization of chaotic early afterdepolarizations in the genesis of cardiac arrhythmias,’’ by Daisuke Sato, Lai-Hua Xie, Ali A. Sovari, Diana X. Tran, Norishige Morita, Fagen Xie, Hrayr Karagueuzian, Alan Garfinkel, James N. Weiss, and Zhilin Qu, which appeared in issue 9, March 3, 2009, of Proc Natl Acad Sci USA (106:2983–2988; f...
AIMS Female gender is a risk factor for long QT-related arrhythmias, but the underlying mechanisms remain uncertain. Here, we tested the hypothesis that gender-dependent function of the post-depolarization 'late' sodium current (I(Na-L)) contributes. METHODS AND RESULTS Studies were conducted in mice in which the canonical cardiac sodium channel Scn5a locus was disrupted, and expression of hu...
