Abstract
OBJECTIVE Comprehensive assessment of hemodynamic significance of a patent ductus arteriosus (PDA) is a common indication to perform targeted neonatal echocardiography (TNE). Impact of implementation of such an assessment on PDA management decisions remains to be reported. The objective of this study is to compare PDA-related hemodynamic information and PDA treatment decisions before and after introduction of TNE service. STUDY DESIGN This was a retrospective cohort study at a tertiary level neonatal intensive care unit in Southwestern Ontario. We investigated two time periods: Epoch-1 (non-TNE 2013-2016) versus Epoch-2 (TNE 2018-2021). We included neonates < 32 weeks with PDA. Data on baseline clinical characteristics, PDA-related echocardiographic parameters, PDA treatment details, and relevant long-term outcomes were collected. Primary outcome was defined as PDA treatment rates and need for multiple courses. Secondary outcomes included availability of PDA hemodynamic data and neonatal mortality/morbidity (PDA-related) RESULTS: A total of 275 neonates were included. A total of 162 were assessed by conventional echocardiography in Epoch-1, whereas 113 were assessed by TNE in Epoch-2. Baseline clinical characteristics were similar. Epoch-2 had more echocardiographic assessments per patient of 2.7 (±1.8) versus 1.9 (± 1.3), p < 0.001 in Epoch1. The mean postnatal age at first echocardiographic assessment was higher in Epoch-2 (12.7 days [ ± 14.6]) than in Epoch-1 (7.9 days [ ± 10.4]), p < 0.001. Comprehensive hemodynamic assessment of PDA-related echocardiographic parameters such as PDA size, shunt pattern, effect on systemic circulation, and pulmonary circulation were higher in Epoch-2. Overall, PDA treatment rates were comparable in the two time periods. The use of multiple courses of treatment was higher in Epoch-1 than in Epoch-2 (47.8 vs. 31.7%, p = 0.047). In Epoch-1, neonates received PDA treatment earlier than in Epoch-2. CONCLUSION With the implementation of the TNE service, increased echocardiographic evaluations per patient were completed with availability of more comprehensive hemodynamic information about PDA. PDA treatment rates were similar in the two epochs, but need for multiple courses were less in TNE era. KEY POINTS · TNE allows comprehensive hemodynamic assessment of PDA.. · Implementation of dedicated TNE service led to increased use of echocardiography to assess PDA.. · Standardized hemodynamic assessment of PDA may allow improved individualization of treatment need..

Abstract
INTRODUCTION Traditionally echocardiography was used by pediatric cardiologists to diagnose congenital heart defects in neonates. Formalized neonatal hemodynamic fellowships have been established where neonatologists acquire advanced echocardiographic skills to gain anatomical, physiological, and hemodynamic information in real time and utilize this information in making a timely and accurate physiology-based clinical decision. AREA COVERED Differences between a comprehensive formal structural echocardiography, neonatologist performed targeted echocardiography and limited assessment on point-of-care-ultrasonography for specific indications have been covered. This article is focused at providing a comprehensive review of the status of echocardiography in the neonatal units, recent advancements and its future prospects in the neonatal intensive care units. EXPERT OPINION Comprehensive guidelines providing the scope of practice, a framework for training, and robust clinical governance process for the neonatologist performed targeted echocardiography have been established. In the last decade, echocardiography has emerged as essential vital bedside diagnostic tool in providing high-quality care to the sick infants in the neonatal units, and it has proved to improve the outcomes in neonates. It is now being considered as a modern hemodynamic monitoring tool. Advances in technology, machine learning, and application of artificial intelligence in applications of echocardiography seem promising adjunct tools for rapid assessment in emergency situations.

Abstract
OBJECTIVE To assess clinical and echocardiography predictors of acetaminophen response for the treatment of patent ductus arteriosus (PDA) in preterm neonates. STUDY DESIGN Retrospective cohort study of preterm infants born <30 weeks, with a diagnosis of hemodynamically significant PDA, who received 1st line treatment with intravenous acetaminophen during the first 2 postnatal weeks. Response was defined by PDA closure or improvement in PDA score of >50%. RESULTS A total of 100 infants were included whose median weight and gestational age at birth were 663 grams and 24.6 weeks respectively. In total, 66 infants were classified as responders and were more likely to have intrauterine growth restriction, exposure to maternal hypertension and chorioamnionitis. Non-response was more common among infants with thrombocytopenia and anemia. CONCLUSION Responders were more likely to be IUGR with echocardiography indices of lower preload. Response to 1st line intravenous acetaminophen therapy is comparable to non-steroidal drugs in preterm infants. Relationship of response to acetaminophen to perinatal characteristics requires further characterization.

Abstract
OBJECTIVE Assess if unit-level PDA management correlates with neurodevelopmental impairment (NDI) at 18-24 months corrected postnatal age (CPA) in extremely preterm infants. STUDY DESIGN Retrospective analysis of infants born at <29 weeks (2014-2017) across two units having distinct PDA strategies. Site 1 utilized an echocardiography-based treatment strategy aiming for accelerated closure (control). Site 2 followed a conservative approach. PRIMARY ENDPOINT NDI, characterized by cerebral palsy, any Bayley-III composite score <85, sensorineural/mixed hearing loss, or at least unilateral visual impairment. RESULTS 377 infants were evaluated. PDA treatment rates remained unchanged in Site 1 but eventually reached 0% in Site 2. Comparable rates of any/significant NDI were seen across both sites (any NDI: 38% vs 36%; significant NDI: 13% vs 10% for Site 1 and 2, respectively). After adjustments, NDI rates remained similar. CONCLUSION PDA management strategies in extremely preterm newborns showed no significant impact on neurodevelopment outcomes at 18-24 months CPA.

Abstract
BACKGROUND Cardiovascular support (CVS) treatment failure (TF) is associated with a poor prognosis in preterm infants. METHODS Medical charts of infants with a birth weight <1500 g who received either dopamine (Dp) or dobutamine (Db), were reviewed. Treatment response (TR) occurred if blood pressure increased >3rd centile for gestational age or superior vena cava flow was maintained >55 ml/kg/min, with decreased lactate or less negative base excess, without additional CVS. A predictive model of Dp and Db on TR was designed and the impact of TR on survival was analyzed. RESULTS Sixty-six infants (median gestational age 27.3 weeks, median birth weight 864 g) received Dp (n = 44) or Db (n = 22). TR occurred in 59% of the cases treated with Dp and 31% with Db, p = 0.04. Machine learning identified a model that correctly labeled Db response in 90% of the cases and Dp response in 61.4%. Sixteen infants died (9% of the TR group, 39% of the TF group; p = 0.004). Brain or gut morbidity-free survival was observed in 52% vs 30% in the TR and TF groups, respectively (p = 0.08). CONCLUSIONS New predictive models can anticipate Db but not Dp effectiveness in preterm infants. These algorithms may help the clinicians in the decision-making process. IMPACT Failure of cardiovascular support treatment increases the risk of mortality in very low birth weight infants. A predictive model built with machine learning techniques can help anticipate treatment response to dobutamine with high accuracy. Predictive models based on artificial intelligence may guide the clinicians in the decision-making process.

Abstract
The patent ductus arteriosus frequently poses a significant morbidity in preterm infants, subjecting their immature pulmonary vascular bed to substantial volume overload. This, in turn, results in concurrent hypoperfusion to post-ductal organs, and subsequently alters cerebral blood flow. In addition, treatment has not demonstrated definitive improvements in patient outcomes. Currently, the optimal approach remains a subject of considerable debate with ongoing research controversy regarding the best approach. This article provides a comprehensive review of existing literature.

Abstract
The purpose of the study is to test whether NT-proBNP serves as a screening tool for low-risk patent ductus arteriosus and safely avoids routine early echocardiography. This is a prospective observational study in preterm infants ≤32 weeks of gestational age. Infants with ≥5100 pg/ml (positive screening) at 48-72 hours of life received comprehensive echocardiography and were treated according to shunt severity. Infants with NT-proBNP below 5100 pg/ml (negative screening) were managed expectantly. The main outcome was need for ductus treatment within the first 7 days of life. One hundred twenty-five infants were included; 82 had a negative NT-proBNP screening and 43 had a positive NT-proBNP screening. No infant (0%) with a negative screening was treated for ductus while 26 (60.4%) with a positive screening were treated (p < 0.001). NT-proBNP avoided a 65.6% of routine echocardiograms. NT-proBNP had an excellent performance to predict PDA treatment (AUC = 0.967).Conclusion: NT-proBNP at 48-72 hours of life has an excellent performance to detect low risk and avoids unnecessary echocardiograms. This may contribute to optimize PDA management in terms of resource utilization.
