In many parts of the world, mostly low- and middle-income countries, timely diagnosis and repair of congenital heart diseases (CHDs) is not feasible for a variety of reasons. In these regions, economic growth has enabled the development of cardiac units that manage patients with CHD presenting later than would be ideal, often after the window for early stabilisation - transposition of the great arteries, coarctation of the aorta - or for lower-risk surgery in infancy - left-to-right shunts or cyanotic conditions...

BACKGROUND: Junctional ectopic tachycardia (JET) after congenital heart disease (CHD) surgery is often self-limiting but is associated with increased risk of morbidity and mortality. Contributing factors and impact of time to achieve rate control of JET are poorly described. METHODS: From January 2010 to June 2015, a retrospective, single-center cohort study was performed of children who developed JET after CHD surgery . We classified the cohort into two groups: patients who achieved rate control of JET in ≤24 hours and in >24 hours...

Congenitally corrected transposition of great arteries (CCTGA) is a rare anomaly described by atrioventricular and ventriculoarterial discordance. On the other hand, mesocardia that is extremely rare includes two relatively well-defined apexes defined by each ventricle with the major axis of the heart lies in the midline. We describe a rare case of an asymptomatic 20-year-old woman with mesocardia, CCTGA, and severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in left ventricular outflow tract...

BACKGROUND: Children with major congenital heart defects are risking impaired cerebral growth, delayed cerebral maturation, and neurodevelopmental disorders. We aimed to compare the cerebral tissue oxygenation of fetuses with major heart defects to that of fetuses without heart defects as estimated by the magnetic resonance imaging modality T2*. T2* is low in areas with high concentrations of deoxyhemoglobin. METHODS AND RESULTS: At gestational age mean 32 weeks (early) and mean 37 weeks (late), we compared the fetal cerebral T2* in 28 fetuses without heart defects to that of 15 fetuses with major heart defects: transposition of the great arteries (n=7), coarctation of the aorta/hypoplastic aortic arch (n=5), tetralogy of Fallot (n=1), hypoplastic right heart (n=1), and common arterial trunk (n=1)...

Purpose of this study was to investigate a potential correlation between the pattern of cerebral veins (CV) on susceptibility-weighted imaging (SWI) and blood oxygen saturation, as well as preoperative brain injury, in neonates with transposition of the great arteries (TGA). Eleven neonates with TGA underwent MRI preoperatively, including SWI, T1- and T2-weighted scans. Images were retrospectively evaluated and appearance of CV was graded from 0 (normal appearance) to 3 (severe prominent appearance). White matter injuries (WMI) and strokes were analysed...

We experienced an arterial switch operation in a patient with d-transposition of the great arteries associated with bilateral intramural coronary arteries from a single coronary ostium. In performing the coronary transfer, intramural course of bilateral coronary arteries was unroofed and coronary ostium was separated into two coronary buttons. The two coronary buttons were translocated to the neo-aorta using modified trap-door technique. The angiogram performed 6 years after the operation revealed well-developed coronary arteries without stenosis, and the patient is doing well 8 years after the operation...

Studies have highlighted the critical role of GATA6 in conotruncal heart defects (CTDs). Nevertheless, relationship between GATA6 variants and different CTDs remains largely unknown. Here GATA6 gene was screened in 542 patients with CTDs using targeted sequencing. Variant frequency was 2.0% (11/542). Three novel variants: c.86C>A (p.A29E), c.296T>A (p.V99D) and c.1254delC (p.S418fs) were identified in patients with transposition of the great arteries, double outlet right ventricle and persistent truncus arteriosus, respectively, but in none of the 400 controls...

Coronary complications in patients with transposition of the great arteries (TGA) after an arterial switch operation (ASO) are relatively rare, but of all the possible postoperative adverse events, they are potentially the most dangerous. The fate of the coronary arteries, which are transplanted during the neonatal ASO, remains uncertain. There is also no consensus regarding their postoperative evaluation, especially in asymptomatic patients. The aim of this study was to present the early results of routinely performed coronary computed tomography angiography (CCTA) in asymptomatic adolescents and young adults with TGA after an ASO...

The field of paediatric ventricular assist device (VAD) support is growing rapidly. Among paediatric patients, those with complex congenital heart disease represent a challenging population for VAD support. This report describes a patient with a remote history of an arterial switch operation for d -transposition of the great arteries who developed ischaemic cardiomyopathy necessitating centrifugal-flow VAD support as a bridge to cardiac transplantation. Because of the unique anatomy and the complicated vascular situation, implantation of the centrifugal-flow VAD and subsequent explantation for cardiac transplantation required modifications to the standard surgical approach...

We present a case of successful bicaval Melody valve implantation to treat severe mitral regurgitation in a 44-year-old man with d-transposition of the great arteries, repaired via a Mustard operation. The patient sustained injury to the anterior mitral valve leaflet during laser extraction of a ventricular pacing lead resulting in acute, severe, symptomatic mitral regurgitation. The presence of systemic venous baffles of similar caliber to right ventricular outflow tract conduits allowed for implantation of Melody valves within each baffle...

The transposition of the great arteries (TGA) is a complex congenital heart disease which usually presents as cyanosis in neonates with limited mixing between the systemic and pulmonary circulatory systems. A delayed diagnosis of TGA can lead to ventricular failure. We report a six-week-old infant who was admitted to the paediatric Intensive Care Unit of the Royal Hospital, Muscat, Oman, in 2016 for bronchiolitis. During admission, she was incidentally diagnosed with TGA and coarctation of the aorta. Postnatal screening, including the use of pulse oximetry, plays a significant role in avoiding a late diagnosis of TGA; however, this screening tool is not widely used in Oman...

Objective Central systolic blood pressure (SBP) is a measure of arterial stiffness and strongly associated with atherosclerosis and end-organ damage. It is a stronger predictor of cardiovascular events and all-cause mortality than peripheral SBP. In particular, for children with congenital heart disease, a higher central SBP might impose a greater threat of cardiac damage. The aim of the study was to analyse and compare central SBP in children with congenital heart disease and in healthy counterparts. Patients and methods Central SBP was measured using an oscillometric method in 417 children (38...

INTRODUCTION: As birth weight is a critical predictor of neonatal congenital heart defect (CHD) outcomes, the common problem of poor fetal growth in this population is clinically important but not well understood. The impact of fetal hemodynamics on fetal growth and birth weight in CHD has not been assessed. Combined cardiac output (CCO) has been used to evaluate patients with structurally normal heart but rarely in CHD. Middle cerebral artery and umbilical artery pulsatility indices (PIs) have been used to evaluate the relative distribution of circulation in patients with CHD...

The double-switch operation for congenitally corrected transposition of the great arteries, in which the morphologic left ventricle is restored to the systemic circulation, is an effective surgical option. This case report describes an atrial switch technique without using supplemental material during the double-switch operation for congenitally corrected transposition of the great arteries associated with persistent left superior vena cava, with the systemic venous blood flow rerouted through the enlarged coronary sinus...
