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
Pulmonary hypertension (PH) in neonates, originating from a range of disease states with heterogeneous underlying pathophysiology, is associated with significant morbidity and mortality. Although the final common pathway is a state of high right ventricular afterload leading to compromised cardiac output, multiple hemodynamic phenotypes exist in acute and chronic PH, for which cardiorespiratory treatment strategies differ. Comprehensive appraisal of pulmonary pressure, pulmonary vascular resistance, cardiac function, pulmonary and systemic blood flow, and extrapulmonary shunts facilitates delivery of individualized cardiovascular therapies in affected newborns.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) is a serious congenital malformation. Given the focus on improving survival in patients with "high-risk" CDH, it is possible that risk factors for low-risk patient with CDH may not be a concern. Left heart failure leads to adverse postoperative outcomes, including the need for extracorporeal membrane oxygenation (ECMO). The purpose of this study was to explore the causes of postoperative left heart failure in the low-risk group. METHODS A retrospective study was conducted on newborns with congenital diaphragmatic hernia who were surgically treated in our hospital from January 2018 to March 2022. Children at low risk were divided into three groups according to the intraoperative repair conditions. Group A was defined as grade A defects repaired by direct suture. Group B was defined as a grade B defect repaired by mesh. Group C was a grade B defect repaired by high-tension suture. The age, gender, weight, perioperative echocardiography, and follow-up of the patients were statistically analyzed. The risk factors of left ventricular dysfunction after surgery in neonates with low-risk congenital diaphragmatic hernia were analyzed. RESULTS A total of 52 low-risk children were included in the study. For children in the low-risk group, there was no significant difference between the low-tension repair group and the high-tension repair group in terms of operation time, thoracic tube drainage time, hospital stay, and long-term survival rate. Group A and group B showed good left ventricular function, while group C showed more decreased left ventricular EF and LVFS (LVEF 54.06 ± 10.28, LVFS 26.94 ± 5.83, p < 0.001). On the comparison of measures of left ventricular size, the mean values of left ventricular end-diastolic diameters(LVDD) and left ventricular end-systolic diameters (LVDS) were significantly difference in group C. Univariate analysis showed that LHR, o/e LHR, operation time, and high-tension repair were the influencing factors of left ventricular dysfunction. Multivariate logistic regression analysis identified risk factors for high-tension repair. Severe left heart dysfunction occurred in 2 patients with ECMO requirement in the high-tension repair group, although the difference was not significant. CONCLUSIONS High-tension repair is a potential cause of left ventricular dysfunction in neonates with low-risk CDH.

Abstract
INTRODUCTION Pulmonary hypertension is a major determinant of postnatal survival in infants with a congenital diaphragmatic hernia (CDH). The current care during the perinatal stabilisation period in these infants might contribute to the development of pulmonary hypertension after birth-in particular umbilical cord clamping before lung aeration. An ovine model of diaphragmatic hernia demonstrated that cord clamping after lung aeration, called physiological-based cord clamping (PBCC), avoided the initial high pressures in the lung vasculature while maintaining adequate blood flow, thereby avoiding vascular remodelling and aggravation of pulmonary hypertension. We aim to investigate if the implementation of PBCC in the perinatal stabilisation period of infants born with a CDH could reduce the incidence of pulmonary hypertension in the first 24 hours after birth. METHODS AND ANALYSIS We will perform a multicentre, randomised controlled trial in infants with an isolated left-sided CDH, born at ≥35.0 weeks. Before birth, infants will be randomised to either PBCC or immediate cord clamping, stratified by treatment centre and severity of pulmonary hypoplasia on antenatal ultrasound. PBCC will be performed using a purpose-built resuscitation trolley. Cord clamping will be performed when the infant is considered respiratory stable, defined as a heart rate >100 bpm, preductal oxygen saturation >85%, while using a fraction of inspired oxygen of <0.5. The primary outcome is pulmonary hypertension diagnosed in the first 24 hours after birth, based on clinical and echocardiographic parameters. Secondary outcomes include neonatal as well as maternal outcomes. ETHICS AND DISSEMINATION Central ethical approval was obtained from the Medical Ethical Committee of the Erasmus MC, Rotterdam, The Netherlands (METC 2019-0414). Local ethical approval will be obtained by submitting the protocol to the regulatory bodies and local institutional review boards. TRIAL REGISTRATION NUMBER NCT04373902.

Prasad R, Saha B, Kumar A. Ventricular function in congenital diaphragmatic hernia: a systematic review and meta-analysis. Eur J Pediatr 2022; 181:1071-1083. [PMID: 34725730 DOI: 10.1007/s00431-021-04303-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 10/19/2021] [Accepted: 10/23/2021] [Indexed: 10/20/2022]
Abstract
There is emerging evidence supporting ventricular function as a prognostic factor in congenital diaphragmatic hernia (CDH). The present systematic review and meta-analysis aimed to determine the predictive value of early ventricular function for survival and extracorporeal membrane oxygenation (ECMO) requirement in newborns with CDH. PubMed, Google Scholar, Cochrane Central Register, Clinical Trial Registry, and Opengrey were accessed. Studies evaluating associations between echocardiographic ventricular function measured ≤ 48 h after birth and survival or ECMO requirement were included. Two independent authors extracted the following data: study and participant characteristics, prognostic factors, and outcome-related data. Eleven studies met the inclusion criteria. Five studies reported on survival, two on ECMO, and four on both outcomes. A moderate risk of bias was found in most of the studies, mainly because of selection, prognostic factors, and confounding biases. For survival (899 participants), pooled sensitivity and specificity were 86% (95% confidence interval [CI], 77-92%) and 44% (95% CI, 25-65%), respectively, in normal left ventricular function. For ECMO need (815 participants), pooled sensitivity and specificity were 39.8% (95% CI, 27-52%) and 88% (95% CI, 80-96%), respectively, in left ventricular dysfunction. Overall certainty of the evidence was graded very low for survival and low for ECMO. Inconsistent reporting of echocardiographic measurements and lack of adjustment for confounding factors were major limitations.Conclusion: Early ventricular dysfunction is a potential prognostic factor in CDH. Standardized echocardiographic measurement reporting and high-quality studies are needed to further elucidate its prognostic significance. What is Known: • Evidence supports the predictive value of echocardiographic measurements in CDH ≤ 24-48 h post-birth. • Ventricular dysfunction has been proposed as a prognostic risk factor. What is New: • Right and left ventricular functions were promising predictors of survival and ECMO requirement in neonates with CDH. • Test characteristics of ventricular function were determined as predictors of survival or need for ECMO. Specific echocardiographic markers of ventricular function can be valuable in determining prognosis.

Abstract
Congenital diaphragmatic hernia (CDH) is associated with high mortality rates and significant pulmonary morbidity, mainly due to disrupted lung development related to herniation of abdominal organs into the chest. Pulmonary hypertension is a major contributor to both mortality and morbidity, however, treatment modalities are limited. Novel prenatal and postnatal interventions, such as fetal surgery and medical treatments, are currently under investigation. Until now, the perinatal stabilisation period immediately after birth has been relatively overlooked, although optimising support in these early stages may be vital in improving outcomes. Moreover, physiological parameters obtained from the perinatal stabilisation period could serve as early predictors of adverse outcomes, thereby facilitating both prevention and early treatment of these conditions. In this review, we focus on the perinatal stabilisation period by discussing the current delivery room guidelines in infants born with CDH, the physiological changes occurring during the fetal-to-neonatal transition in CDH, novel delivery room strategies and early predictors of adverse outcomes. The combination of improvements in the perinatal stabilisation period and early prediction of adverse outcomes may mitigate the need for specific postnatal management strategies.
