OBJECTIVES: Predicting whether balloon atrial septostomy (BAS) will be necessary after birth for fetuses with d-transposition of the great arteries (d-TGA) remains challenging. We sought to determine whether measurements obtained during fetal maternal hyperoxygenation (MH) testing can improve our ability to predict need for postnatal BAS. METHODS: Forty-one mothers carrying fetuses with d-TGA with either intact ventricular septum or small ventricular septal defect measuring <3mm underwent MH testing between 33-38 weeks gestation...

OBJECTIVE: To compare the efficacy of low vs conventional dose intravenous paracetamol in early closure of haemodynamically significant patent ductus arteriosus within 7 days of life. METHODS: Preterm infants (<32 weeks of gestation) having echocardiographic evidence of hsPDA were given low dose (15 mg/kg initially followed by 7.5 mg/kg every 6 hourly) vs conventional dose (15 mg/kg every 6 hourly) for 5-7 days. RESULTS: In total, 56 infants (28 in each group) were enrolled...

Background : Patent ductus arteriosus (PDA) is a prevalent congenital heart defect in premature infants, associated with significant morbidity and mortality. Accurate and timely diagnosis of PDA is crucial, given the vulnerability of this population. Methods : We introduce an artificial intelligence (AI)-based PDA diagnostic support system designed to assist medical professionals in diagnosing PDA in premature infants. This study utilized electronic health record (EHR) data from 409 premature infants spanning a decade at Severance Children's Hospital...

Transcatheter closure has become a common treatment method for patent ductus arteriosus in premature infants at many centres; however, many remain uncertain about the ability to perform the procedure in the catheterisation laboratory for infants requiring high-frequency ventilation. This study presents our centre's experience following the implementation of neonatal ventilatory guidelines, which resulted in 100% procedural success without any procedural or respiratory adverse events.

Reversed flow in the basilar artery can be acquired or congenital. Acquired reversed flow in the basilar artery can result from acute thrombosis of the basilar artery or retrograde vertebral artery flow. Congenital continuous retrograde basilar artery flow has not been described. We report a 2-day-old male presenting with hypocalcemic seizures which led us to obtain a Duplex echoencephalogram. An echocardiogram was subsequently ordered. In the coronal plane through the anterior fontanelle, retrograde flow was seen in the basilar artery and the right vertebral artery...

BACKGROUND: Transcatheter closure of the patent ductus arteriosus (PDA) in premature infants is currently dependent on fluoroscopic guidance and transportation to the catheterization laboratory. AIM: We describe a new echocardiographically guided technique to allow our team to move to the bedside at the neonatal intensive care unit (NICU) of the referring center for percutaneous treatment of PDA in premature infants. METHODS: This is a single-center, retrospective, primarily descriptive analysis...

RATIONALE: A hemodynamically significant patent ductus arteriosus (hsPDA) in premature infants has been associated with bronchopulmonary dysplasia (BPD) and pulmonary hypertension (PH). However, these associations remain incompletely understood. OBJECTIVES: The aim was to assess the association between hsPDA duration with clinical outcomes, PH, and phenotypic differences on lung MRI. METHODS: This retrospective cohort study identified all infants with BPD <32 weeks gestation who also underwent a research lung MRI <48 weeks postmenstrual age (PMA) from 2014-2022...

BACKGROUND: Hyperglycemia in pregnancy (HGP) has generally been considered a risk factor associated with adverse outcomes in offspring, but its impact on the short-term outcomes of very preterm infants remains unclear. METHODS: A secondary analysis was performed based on clinical data collected prospectively from 28 hospitals in seven regions of China from September 2019 to December 2020. According to maternal HGP, all infants were divided into the HGP group or the non-HGP group...

BACKGROUND: The off-label use of contrast-enhanced ultrasound has been increasingly used for pediatric patients. OBJECTIVE: The purpose of this retrospective study is to report any observed clinical changes associated with the intravenous (IV) administration of ultrasound contrast to critically ill neonates, infants, children, and adolescents. MATERIALS AND METHODS: All critically ill patients who had 1 or more contrast-enhanced ultrasound scans while being closely monitored in the neonatal, pediatric, or pediatric cardiac intensive care units were identified...

OBJECTIVES: The management of patent ductus arteriosus (PDA) is a critical concern in premature infants, and different hospitals may have varying treatment policies, fluid management strategies, and incubator humidity. The Asian Neonatal Network Collaboration (AsianNeo) collected data on prematurity care details from hospitals across Asian countries. The aim of this study was to provide a survey of the current practices in the management of PDA in premature infants in Asian countries...

BACKGROUND: Neonatal air transportation is a crucial means of moving critically ill or sick neonates to specialized neonatal intensive care units or medical centers for consultation, regardless of distance or geographical limits. Proper preparation and consideration of air transport can help alleviate medical emergencies and ensure safe delivery. However, crewmembers and neonates may face stress during transportation. To date, there are few studies on neonatal air transportation in Taiwan. CASE REPORT: We present the case of a late preterm neonate born with neonatal respiratory distress syndrome and polycythemia, who was also diagnosed with patent ductus arteriosus and mild pulmonary arterial hypertension on echocardiography...
