Single Coronary Origin From Right Coronary Sinus With Intraseptal Course: How to Make Diagnosis by Echocardiography.

We describe a rare case of a male adolescent with anomalous aortic origin of the left coronary artery from the right sinus with intraseptal course (L-ACAO-IS), which was diagnosed at transthoracic echocardiography. The case we presented confirms how echocardiography is accurate in the diagnosis of even challenging coronary artery origin anomalies such as L-ACO-IS. Coronary artery origin evaluation should be an integral part of echocardiography examinations in infants, children, and young adults, especially those undergoing physical activity.

Hypothyroidism in Patients with Down Syndrome: Prevalence and Association with Congenital Heart Defects.

This population-based study aimed to assess the prevalence of congenital hypothyroidism (CH) and overt hypothyroidism (OH) and their association with congenital heart defects (CHDs) in patients with Down syndrome (DS). The population included all live births residing in Tuscany (Italy) diagnosed with DS recorded in the Registry of Congenital Defects and in the Registry of Rare Diseases of Tuscany in the years 2003-2017. The prevalence of CH and OH in DS patients was calculated by sex and by period.

Comprehensive Two-Dimensional Pediatric Echocardiographic Nomograms for Coronary Artery Sizes in Caucasian Children and Comparison among Major Nomograms.

Background: Although coronary artery nomograms in children have been published, data on Caucasian children are lacking. The aim of this study is to provide: (i) a full dataset of coronary artery diameters in healthy children and (ii) a comparison among major previous nomograms.

Materials And Methods: We prospectively evaluated 606 healthy subjects (age range, 1 days-<18 years; median age 8.

Normal Values for Echocardiographic Myocardial Work in a Large Pediatric Population.

Background: Echocardiographic myocardial work is a new load-independent echocardiographic technique to quantify left ventricle (LV) systolic performance. Our aim was to establish normal values for echocardiographic myocardial work in a large population of healthy children.

Methods: For all the subjects 4-, 2-, and 3-chamber-view videos were stored.

Personalized Approach in Transcatheter Palliation of Congenital Heart Disease with Duct-Dependent Pulmonary Circulation: Right Ventricular Outflow Tract Stenting vs. Arterial Duct Stenting.

Despite significant improvements in techniques, the treatment of neonates and infants with congenital heart disease resulting in duct-dependent pulmonary circulation is still significantly challenging. Despite current trends toward early primary surgical repair, temporary palliation is still necessary in those patients who are at high surgical risk for complete correction due to unfavorable clinical or anatomic characteristics. Recent advances in interventional cardiology have led to the emergence of right ventricular outflow tract and arterial duct stenting as cost-effective alternatives to surgical palliation in high-risk surgical candidates or whenever short-term pulmonary blood flow support is anticipated.
