Revealing Mitral Valve Cleft Using Real-Time 3-Dimensional Echocardiography in Children with Mitral Regurgitation
AbstractMitral valve cleft (MVC) is the most common cause of congenital mitral regurgitation (MR). MVC may be located on the anterior or posterior leaflets. We evaluated children with moderate-to-severe MR using 3D transthoracic echocardiography (3DTTE) to diagnose MVC and determine the location, shape and size of MVC. Twenty-one patients under 18  years of age with moderate-to-severe MR without symptoms who were suspected of having MVC were included in the study. The patients’ history and clinical data were obtained from the medical records. 2D and 3D imaging were performed with a high-quality machine (EPIQ CVx). A ven...

The Association Between Congenital Heart Disease and Autism Spectrum Disorder: A Systematic Review and Meta-Analysis
AbstractCongenital heart disease (CHD) is linked to an increased incidence of neurodevelopmental impairments in young patients. Given the number of published studies on this topic, a synthesis of the literature is timely and needed. We performed a systematic review and meta-analysis of the medical literature to assess the evidence linking CHD to incidence of autism spectrum disorder (ASD). A systematic review of studies on CHD and ASD in PubMed, Cochrane and Institute for Scientific Information (ISI) from 1965 to May 2021 was conducted. Quantitative estimates of association between CHD and ASD were extracted from eligible ...

Transcatheter Closure of a Coronary Artery Fistula in a Neonate with Tetralogy of Fallot
We present the case of a 32-week premature boy weighing 1.79  kg with TOF, confluent branch pulmonary arteries, major aortopulmonary collaterals, and right coronary artery to main pulmonary artery fistula. The patient demonstrated evidence of coronary steal into the pulmonary vasculature with an elevation in the troponin level without hemodynamic instability , and subsequently underwent successful transcatheter occlusion of the fistula via right common carotid access using a Medtronic 3Q microvascular plug. This case demonstrates the realistic potential for early coronary steal in this physiology and possibility of transc...

A Preliminary Study of One Year Safety and Tolerability of Attention-Deficit/Hyperactivity Disorder Medications in Youth with Fontan Palliation or Heart Transplant
AbstractThere are no published studies that examine the safety and tolerability of medication to treat attention-deficit/hyperactivity disorder (ADHD) in children with histories of Fontan palliation (Fontan) or heart transplant (HT), despite the high prevalence of ADHD in these populations. To address this gap, we examined the cardiac course, somatic growth, and incidence of side effects for one year after medication initiation amongst children with Fontan or HT and comorbid ADHD. The final sample comprised 24 children with Fontan (12 medication-treated, 12 control) and 20 children with HT (10 medication-treated, 10 contro...

The Need for Surgery After Vascular or Cardiac Trauma, or Technical Adverse Events in the Congenital Cardiac Catheterization Laboratory
This study analyzes the outcomes of specific types of AE that are most likely to require immediate surgical intervention. Data from the C3PO registry were analyzed to identify specific types of significant vascular/cardiac trauma or technical adverse events (stent/device/coil embolization/migration). The relationship between these AE and an “adverse outcome” (defined as either surgery, ECMO, or death) were analyzed. Between 01/2014 and 12/2017, 25,731 cases were entered into the C3PO registry. Vascular or cardiac trauma were observed in 92 cases (0.36% cases in C3PO), and technical adverse events were observed in 176 c...
