Umbilical vein anomalies are a rare congenital defect, which have been associated with absent ductus venosus, with few cases also involving a congenital diaphragmatic hernia. We describe a case of postnatal development of an anterior diaphragmatic hernia of Morgagni in a four-year-old patient diagnosed prenatally with mesocardia, absent ductus venosus with a large umbilical vein, a large secundum atrial septal defect, and patent ductus arteriosus.

Perinatal mortality remains high among fetuses diagnosed with Ebstein's anomaly of the tricuspid valve. The subgroup of patients with pulmonary valve regurgitation is at particularly high risk. In the setting of pulmonary valve regurgitation, early constriction of the ductus arteriosus may be a novel perinatal management strategy to reduce systemic steal resulting from circular shunt physiology. We report the use of chronic antepartum maternal oxygen therapy for constriction of the fetal ductus arteriosus and modulation of fetal pulmonary vascular resistance in a late presentation of Ebstein's anomaly with severe tricuspid valve regurgitation, reversal of flow in the ductus arteriosus, and continuous pulmonary valve regurgitation...

BACKGROUND: Smaller femoral arterial sheaths may be associated with fewer vascular complications. The 3.3 Fr Mongoose(®) Pediavascular pigtail catheter is a catheter that allows higher flow rates, potentially resulting in improved angiographic quality. We reviewed our experience with this small catheter during patent ductus arteriosus (PDA) closure. MATERIALS AND METHODS: Review of patients ≤20 kg in whom the Mongoose(®) catheter was used during PDA closure from 12/13 to 4/15...

Persistent pulmonary hypertension (PPHN) is a consequence of failed pulmonary vascular transition at birth and leads to pulmonary hypertension with shunting of deoxygenated blood across the ductus arteriosus (DA) and foramen ovale (FO) resulting in severe hypoxemia, and it may eventually lead to life-threatening circulatory failure. PPHN is a serious event affecting both term and preterm infants in the neonatal intensive care unit. It is often associated with diseases such as congenital diaphragmatic hernia, meconium aspiration, sepsis, congenital pneumonia, birth asphyxia and respiratory distress syndrome...

In neonates, the management of ductus dependent pulmonary circulation is challenging. There have been three palliative therapies for this lesion: the modified Blalock-Taussig shunt, ductal stenting and prostaglandin E infusions, for maintaining the ductal patency before definite operations. Debates remain with regard to the indications and disadvantages of three palliative therapies. The aim of this article is to give a brief review of these three palliative therapies.

OBJECTIVE: Patent ductus arteriosus (PDA) is common in preterm infants and is associated with significant morbidities. B type natriuretic peptide (BNP) is synthesized in the ventricles secondary to volume overload and excreted as urinary N-terminal pro-brain natriuretic peptide (NT-proBNP). STUDY DESIGN: We report an observational prospective study of 64 preterm infants with birth weight ⩽1000 g. Echocardiographic parameters were obtained from clinical echocardiograms performed in the first week of life...

A 4-day-old female Holstein Friesian calf was presented for evaluation of cyanosis and dyspnea. On auscultation, severe bronchovesicular sounds and a systolic heart murmur of grade IV/VI above the tricuspid valve were found. On echocardiography, a marked dextroposition of the aorta (> 50% originating from the right ventricle), leading to both great arteries arising from the right ventricle - a so-called double-outlet right ventricle - was detected. Two ventricular septal defects were present, one in the perimembranous, subpulmonary region, the other non-committed in the muscular region...

BACKGROUND: Diazoxide, an ATP-sensitive potassium channel opener, is the main therapeutic agent for treating hyperinsulinemic hypoglycemia. We aimed to determine the in vivo ductus-dilating effects of diazoxide in fetal and neonatal rats. METHODS: Near-term rat pups delivered via a cesarean section were housed at 33°C. After rapid whole-body freezing, The ductus arteriosus (DA) diameter was measured using a microscope and a micrometer. Full-term pregnant rats (gestational day 21) were intraperitoneally injected with diazoxide (10 and 100 mg/kg) 4 h before delivery, and the neonatal DA diameter was measured at 0, 30, or 60 min after birth...

BACKGROUND: Patent ductus arteriosus (PDA) treatment is typically pharmacologic, but if unsuccessful, surgical ligation is commonly performed. High-frequency jet ventilation (HFJV) is used at the University of Iowa Stead Family Children's Hospital for extremely low birth weight infants. Historically, neonates requiring PDA ligation were temporarily transferred to conventional ventilation (CV) prior to surgery. OBJECTIVE: The objective of this study was to determine whether conversion was necessary...

The objective of the study was to retrospectively analyse the cardiovascular effects that occurs following the transvascular occlusion of patent ductus arteriosus in dogs. Sixteen anaesthesia records were included. Variables were recorded at the time of placing the arterial introducer, occlusion of the ductus, and from 5 to 60min thereafter, including, among the other, heart rate, systolic, diastolic and mean arterial blood pressure. The maximal percentage variation of the aforementioned physiological parameters within 60min of occlusion, compared with the values recorded at the introducer placing, was calculated...

BACKGROUND: Breast milk alone, given at standard recommended volumes (150 to 180 mL/kg/d), is not adequate to meet the protein, energy, and other nutrient requirements of growing preterm or low birth weight infants. One strategy that may be used to address these potential nutrient deficits is to give infants enteral feeds in excess of 200 mL/kg/d ('high-volume' feeds). This approach may increase nutrient uptake and growth rates, but concerns include that high-volume enteral feeds may cause feed intolerance, gastro-oesophageal reflux, aspiration pneumonia, necrotising enterocolitis, or complications related to fluid overload, including patent ductus arteriosus and bronchopulmonary dysplasia...
