IgG2 rules: N-acetyl-β-D-glucosamine-specific IgG2 and Th17/Th1 cooperation may promote the pathogenesis of acute rheumatic heart disease and be a biomarker of the autoimmune sequelae of .

Antecedent group A streptococcal pharyngitis is a well-established cause of acute rheumatic fever (ARF) where rheumatic valvular heart disease (RHD) and Sydenham chorea (SC) are major manifestations. In ARF, crossreactive antibodies and T cells respond to streptococcal antigens, group A carbohydrate, N-acetyl-β--glucosamine (GlcNAc), and M protein, respectively, and through molecular mimicry target heart and brain tissues. In this translational human study, we further address our hypothesis regarding specific pathogenic humoral and cellular immune mechanisms leading to streptococcal sequelae in a small pilot study.

Isolated ostial left main coronary artery stenosis causing ischemic cardiomyopathy in a child with bicuspid aortic valve: Role of echocardiography in diagnosis and follow-up.

Bicuspid aortic valve (BAV) is the most common congenital cardiac defect, commonly associated with valve dysfunction and coarctation of aorta. Rarely, BAV can be associated with abnormalities of the coronary arteries, the most common of which are ectopic coronary origins. In this report, we present a case of a 2-year-old child with BAV, without coexisting supravalvular aortic stenosis, who was found to have a left main coronary ostio-proximal stenosis, leading to ischemic cardiomyopathy and congestive heart failure.

Intramural Coronary Artery in Truncus Arteriosus: Importance of Preoperative Echocardiographic Diagnosis and Impact on Surgical Planning.

Coronary artery anomalies are known to be associated with truncus arteriosus (common arterial trunk). Delineation of coronary anatomy preoperatively is important to avoid complications intraoperatively and postoperatively. We report the case of a 12-year-old boy with repaired truncus arteriosus who presented with moderate to severe truncal valve regurgitation and severe conduit stenosis.

Autoimmunity Against the Heart and Cardiac Myosin in Children With Myocarditis.

Background: Host autoimmune activity in myocarditis has been proposed to play a role in development of cardiac disease, but evidence of autoimmunity and relationship to outcomes have not been evaluated in pediatric myocarditis.

Methods: We performed a multi-institutional study of children with clinical myocarditis. Newly diagnosed patients were followed for up to 12 months and previously diagnosed patients at a single follow-up for serum levels of autoantibodies to human cardiac myosin, beta-adrenergic receptors 1 and 2, muscarinic-2 receptors, and antibody-mediated protein kinase A (PKA) activation in heart cells in culture.

High Frequency of Detection by PCR of Viral Nucleic Acid in The Blood of Infants Presenting with Clinical Myocarditis.

Specific viruses are associated with pediatric myocarditis, but the prevalence of viral DNAemia detected by blood polymerase chain reaction (PCR) is unknown. We evaluated the prevalence of known cardiotropic viruses (enterovirus, adenovirus, human herpesvirus 6, and parvovirus B19) in children with clinical myocarditis (n = 21). Results were compared to pediatric controls with similar viral PCR testing.

Complete repair of Ebstein anomaly in neonates and young infants: a 16-year follow-up.

Objective: The purpose of this study was to review the long-term outcome of patients with Ebstein anomaly who underwent complete repair as neonates and young infants.

Methods: Between March 1994 and May 2010, 32 patients (23 neonates and 9 young infants) underwent surgery for Ebstein anomaly. Mean weight was 3.

Repair of Ebstein's anomaly in the symptomatic neonate: an evolution of technique with 7-year follow-up.

Background: Ebstein's anomaly in the severely symptomatic neonate is usually fatal. Until recently, successful repair has not been reported and various palliative operations have been associated with prohibitive mortality. Recently, we published our initial results with biventricular repair in 3 severely symptomatic neonates.
