BACKGROUND: The arterial ductus is a major communicative pathway which is naturally patent in the fetus, connecting the body of the major pulmonary artery to the descending aorta. Although usually closing on its own, the patent ductus arteriosus (PDA) may remain open in the second postnatal week due to a lack of prompt diagnosis in the initial days of life or an absence of prompt treatment. OBJECTIVES: To prevent the untoward sequelae of patency of the ductus arteriosus, and to avoid invasive surgery at higher ages, the researchers in the present study embarked on determining the effects of oral ibuprofen during the second postnatal week on newborns with patent ductus arteriosus...

Congenital pulmonary venous anomalies are not uncommon that can occur either in isolation or in association with different forms of congenital heart disease. Clinical presentation of these anomalies may vary from the relatively benign single anomalous partial pulmonary venous return to life-threatening critical obstructed total anomalous pulmonary venous return. Accurate delineation of these anomalies and accompanied cardiovascular anomalies are crucial to guide decision making in these patients. Low-dose high-pitch dual-source 256-detector multidetector computed tomographic angiography is a fast and reliable imaging modality allowing comprehensive noninvasive anatomic imaging in neonates and children with congenital pulmonary venous anomalies with lower radiation doses and should be preferred for these patients after transthoracic echocardiography...

Mitochondrial dysfunction leads to reactive oxygen species (ROS) overload, exacerbating injury in myocardial infarction (MI). As a receptor for translocases in the outer mitochondrial membrane (Tom) complex, Tom70 has an unknown function in MI, including in melatonin-induced protection against MI injury. We delivered specific small interfering RNAs against Tom70 or lentivirus vectors carrying Tom70a sequences into the left ventricles of mice or to cultured neonatal murine ventricular myocytes (NMVMs). At 48 h post-transfection, the left anterior descending coronary arteries of mice were permanently ligated, while the NMVMs underwent continuous hypoxia...

BACKGROUND: Myocardial remodeling and cardiac dysfunction prevention may represent a therapeutic approach to reduce mortality in patients with myocardial infarction (MI). We investigated the effects of Lin28a in experimental MI models, as well as the mechanisms underlying these effects. METHODS: Left anterior descending (LAD) coronary artery ligation was used to construct an MI-induced injury model. Neonatal cardiomyocytes were isolated and cultured to investigate the mechanisms underlying the protective effects of Lin28a against MI-induced injury...

The Forkhead box-containing protein, O subfamily 3 (FoxO3) transcription factor negatively regulates myocardial hypertrophy, and its transcriptional activity is finely conditioned by diverse posttranslational modifications, such as phosphorylation, acetylation, ubiquitination, methylation and glycosylation. Here, we introduce a novel modification of the FoxO3 protein in cardiomyocytes: poly(ADP-ribosyl)ation (PARylation) mediated by poly(ADP-ribose) polymerase-1 (PARP1). This process catalyzes the NAD(+)-dependent synthesis of polymers of ADP-ribose (PAR) and their subsequent attachment to target proteins by PARPs...

A female preterm infant was born to a non-consanguineous couple at 35 weeks of gestation. On day 8 of life, while on full feeds, she developed prolonged apnoea and bradycardia, requiring respiratory support. Her abdomen was soft with unremarkable serial abdominal X-rays. Her septic screen was negative. Metabolic acidosis was worsening despite treatment. Echocardiography showed evidence of high pulmonary pressures. With further deterioration, an ultrasound scan of the abdomen was requested in view of the rising suspicion of abdominal pathology in the absence of sepsis and metabolic disorders...

INTRODUCTION: Maternal diabetes mellitus is associated with an increased risk of fetal and neonatal morbidity and mortality. Usual screening tests have not proved to be good prognostic indicators of fetal distress. Fetal cardiodynamics is potentially a useful screening tool. AIM: To determine if cardiodynamics of the fetus differ in pregnancy with diabetes requiring insulin than those without and to determine whether cardiodynamics predict fetal and neonatal outcomes...

This study aimed to explore the pattern of lung ultrasound (LUS) in newborns with congenital heart disease (CHD) and to investigate the accuracy of LUS assessing pulmonary overflow (PO) during the first days of life. Lung ultrasound was performed in 51 newborns during the first days of life, and newborns were classified in two groups depending on the predisposition to develop POas evaluated by the abundance of B-lines. The results were compared to the physical examination (PE), chest X-ray, and echocardiography...

An intramural coronary artery in the setting of truncus arteriosus (common arterial trunk) is an uncommon association. Following an uneventful surgical repair, a neonate developed a low cardiac output state deteriorating into cardiac arrest shortly after arrival into the intensive care unit, requiring extracorporeal membrane oxygenation support. Echocardiography and angiography showed occlusion of the left coronary artery, prompting emergency surgical reexploration. A "slit-like" orifice with an intramural left coronary artery was successfully unroofed, allowing full recovery...

: Neonatologists have begun using superior vena cava flow as assessed by functional echocardiography to facilitate real-time decision making on cardiovascular care. This review aims to describe the basis of the technique, summarise the evidence for its use and compare the technique to existing clinical, biochemical and radiological techniques for assessing neonatal circulatory status. CONCLUSION: Although echocardiographic measurements of superior vena cava flow, like other measures of perfusion, are not perfect, their non-invasive nature and ability to facilitate real-time decision making means that at present they remain the best available methodology of monitoring central perfusion in the neonatal population...

We present a case of an ex-30 week premature male infant diagnosed postnatally with Tetralogy of Fallot, hemitruncus, and discontinuous pulmonary arteries (PAs) at 6 days of life. The patient was diagnosed by echocardiography, and the diagnosis was confirmed on subsequent dual-energy chest CT angiogram. In our patient, the left PA arose directly from the aorta, whereas the right PA originated normally from the right ventricular outflow tract. At 9 days of life, he underwent successful surgical palliation with placement of a modified Blalock-Taussig (aortopulmonary) shunt from the base of the left subclavian artery to the anomalously connected left PA along with anastomosis together of the right and left branch PAs to establish continuity with the main PA...

D-transposition of the great arteries (D-TGA) is the most commonly diagnosed cyanotic congenital heart disease presenting in the neonatal period. The survival after an arterial switch operation, with freedom from adverse cardiovascular events, has been reported to be as high as 93% at 25 years. However, despite excellent surgical outcomes, there continues to be significant preoperative morbidity and potential mortality due to compromise in the delivery room from foramen ovale closure requiring urgent balloon atrial septostomy for stabilization in the first minutes of life...

The use of 2-D strain speckle tracking echocardiography in B-mode images from tissue Doppler (TD) recordings was compared with its use in regular gray-scale (GS) recordings in healthy and asphyxiated neonates at days 1-3. Single-cycle and three-cycle longitudinal deformation indices were assessed. Median B-mode frame rates were 38/s (TD) and 77/s (GS). Systolic indices were similar for TD and GS recordings. Diastolic indices were lower for TD recordings. Single-cycle and three-cycle indices were equal. TD and GS recordings were similar in reproducibility, except for single-cycle inter-observer peak systolic strain rate and three-cycle intra-observer strain rate during atrial systole...

BACKGROUND: Antenatal diagnosis of congenital heart defects (CHD) can impact outcomes in neonates with severe CHD. Obstetric screening guidelines and the indications for fetal echocardiography (FE) have evolved in an attempt to improve the early prenatal detection of CHD. Analyzing yield for specific indications will help clinicians better stratify at-risk pregnancies. METHODS: Retrospective cohort study of all FE performed between 2000 and 2010 at a single tertiary care academic medical center in New York City...
