Abstract
OBJECTIVE Current guidelines suggest routine echocardiography (ECHO) in the acute phase to exclude a cardiac source for neonatal arterial ischemic stroke (NAIS). However, the commonly assumed embolic origin from a cardiac source for NAIS is challenged and the need for ECHO in NAIS remains questionable, especially during the era of standard fetal anomaly scanning. Our hypothesis is that any complex cardiac defects potentially causing NAIS would likely be detected during routine prenatal scans, thus possibly making routine postnatal ECHO redundant. This study aimed to determine the prevalence of significant cardiac risk factors and evaluate the necessity of routine postnatal ECHO in NAIS during the routine use of prenatal fetal sonography. STUDY DESIGN Retrospective review of 54 infants diagnosed with NAIS via brain magnetic resonance imaging who underwent an ECHO evaluation during the acute period to exclude potential cardiac origins for NAIS. RESULTS Postnatal ECHO revealed no intracardiac thrombus or vegetation, and only identified structural heart anomalies in three (5%) infants. Interestingly, these three cases had already been diagnosed with syndromic conditions or chromosomal malformations prenatally. In the remaining infants, postnatal ECHO was either normal or showed minor abnormalities unlikely to have contributed to the stroke. The detection rates of complex cardiac anomalies from prenatal scans and postnatal ECHO were statistically similar (p = 0.617). CONCLUSION The probability of ECHO to exclude cardiac sources for NAIS is so low that in the era of standard fetal anomaly scanning, routine postnatal ECHO may not be necessary for all NAIS infants, except when chromosomal malformations are detected. KEY POINTS · Guidelines recommend an acute phase ECHO to identify a cardiac source of NAIS.. · ECHO not effective at excluding NAIS's cardiac origin for infants with normal fetal scans.. · Routine postnatal ECHO is unnecessary in NAIS infants, except with genetic abnormalities..

Abstract
Background Perinatal asphyxia is a condition associated with multiple organ dysfunctions inclusive of cardiovascular dysfunction. Neurologic predictors of survival have been studied, but little has been reported regarding cardiovascular signs and their role in determining outcome in asphyxia. Objective The study aimed to determine the relationship between cardiovascular signs and outcomes in asphyxiated newborns with hypoxic ischaemic encephalopathy. Methods This was a cross sectional study involving asphyxiated new-born babies recruited within the first 24 hours of life. Hypoxic ischaemic encephalopathy staging was done using Sarnat and Sarnat staging. All patients had a detailed cardiovascular examination on admission, after initial resuscitation (30 – 60 minutes) into admission, and were followed till final outcome: discharge or death. Results Eighty-five asphyxiated new-borns with HIE were studied over seven months. Abnormal cardiovascular-related signs identified in the patients included respiratory distress (64.7%), small volume pulse (57.6%), hypotension (52.9%), hypoxemia (48.2%) and shock (32.9%). Five babies died. None of the clinical signs had a significant relationship with mortality. Conclusion Abnormal cardiovascular signs increased with the progression of HIE staging but had no relationship with mortality.

Abstract
BACKGROUND More than 50% of newborns with congenital heart disease (CHD) are unrecognized at birth; however, the use of echocardiogram (Echo) for diagnosing CHD in newborns with asymptomatic, non-syndromic cardiac murmurs (ANCM), has not been systematically reviewed yet. We aimed to identify the incidence of CHD diagnosed with Echo and systematically review whether Echo should be recommended in this patient group. METHODS The methodology utilized in this systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework. Using the MEDLINE, EMBASE, Web of Science, and Cochrane Library databases, we performed a systematic review of publications reporting CHD diagnosed with Echo in newborns with cardiac murmurs. The quality of the included studies was evaluated using the Study Quality Assessment Tools developed by the National Institutes of Health. RESULTS Of the 630 studies screened, six cohort studies, four cross-sectional studies, and two case reports were included in this review. The incidence of cardiac murmurs ranged from 0.6-8.6%. Among the 1928 newborns with ANCM, 719 (37.3%) were diagnosed with Echo as having CHD, and ventricular septal defect was the most common congenital malformation. More than 50% of the newborns showed moderate CHD necessitating outpatient cardiology follow-up, and 2.5% had severe CHD requiring immediate interventions, such as cardiac catheterization and heart surgery. CONCLUSIONS In this systematic review, a high incidence of CHD in newborns with ANCM was detected using Echo. This indicates that the use of Echo for diagnosing CHD in healthy newborns with cardiac murmurs could be helpful in earlier detection of CHD, thereby improving clinical outcomes for newborns with severe CHD.

Abstract
BACKGROUND The correlation between heart murmur and congenital heart disease (CHD) is complex and varies with observed population. METHODS Ninety consecutive newborns (41 with heart murmur and 49 controls) were routinely examined with auscultation and echocardiography. Intensity and characteristics of heart murmur, presence and type of CHD were recorded. Echocardiographic findings were considered as benchmark. RESULTS Heart murmur was related to the presence of ostium secundum [odds ratio (OR) 4.2], patent ductus arteriosus (OR 11.9), tricuspidal regurgitation (OR 9.5), muscle ventricular septal defect (VSD) (OR 12.3), membranous VSD (OR 9.7), and any CHD (OR 26.7) (P < 0.05 in all cases). Diagnostic accuracy of clinical examination with a finding of heart murmur was 83%, lower if considering single CHD (58-69%), negative predictive value 90%, and positive predictive value 76%. Patients with any CHD, tricuspidal regurgitation and muscle VSD were characterized by a more intense heart murmur. In case of concomitant multiple CHD, intensity of heart murmur correlated with the number of congenital heart anomalies. CONCLUSION Diagnostic accuracy of heart murmur at clinical examination (83%) declines when single CHDs are considered. Higher negative predictive value and lower positive predictive value suggest an echocardiographic second-level confirmation in the case of heart murmur at clinical examination suspected for CHD, probably unnecessary in the case of negative auscultative findings. Heart murmur intensity correlates with the number of concomitant congenital heart anomalies.

Abstract
In January of 2012, University of Arkansas for Medical Sciences began implementation of a critical congenital heart disease screening program to identify newborns with structural heart defects. The screening used motion tolerant pulse oximeters in direct sequence to measure the oxygen levels in the right hand and either foot of eligible newborns. Exclusion criteria included echocardiogram prior to discharge, age greater than 7 days with continuous neonatal intensive care unit monitoring, or death or transfer prior to discharge. Of the 1905 infants screened, 3 infants failed screening. Two of the infants had atrial septal defects, and 1 had a patent foramen ovale, which was considered a false positive. After planning and education, the implementation of critical congenital heart disease pulse oximetry screening was successful. With only 1 false positive in our high-risk population, this should encourage other institutions to begin screening eligible infants.

Abstract
Most important types of congenital heart disease can be recognized early during prenatal or neonatal screening. However, a substantial proportion of cardiac defects are not diagnosed in due time. Such delay may lead to serious complications or even death. This article reviews the impact of screening strategies upon the outcome in pediatric cardiac patients.

BACKGROUND When medical treatment of a symptomatic arterial duct in a preterm infant fails, management is surgical. PATIENTS AND METHODS 10 preterm neonates referred to a tertiary cardiac centre for treatment of a symptomatic patent arterial duct who underwent cardiac catheterisation with the intention of device closure. RESULTS Successful catheter device closure of the arterial duct in nine preterm infants is described. CONCLUSION In selected cases, catheter device closure may offer an alternative to thoracotomy and surgical ligation.

Abstract
Objectives: Congenital heart defects (CHD) are an important cause of death and morbidity in early childhood, but the effectiveness of alternative newborn screening strategies in preventing the collapse or death—before diagnosis—of infants with treatable but life-threatening defects is uncertain. We assessed their effectiveness and efficiency to inform policy and research priorities.Methods: We compared the effectiveness of clinical examination alone and clinical examination with either pulse oximetry or screening echocardiography in making a timely diagnosis of life-threatening CHD or in diagnosing clinically significant CHD. We contrasted their cost-effectiveness, using a decision-analytic model based on 100,000 live births, and assessed future research priorities using value of information analysis.Results: Clinical examination alone, pulse oximetry, and screening echocardiography achieved 34.0, 70.6, and 71.3 timely diagnoses per 100,000 live births, respectively. This finding represents an additional cost per additional timely diagnosis of £4,894 and £4,496,666 for pulse oximetry and for screening echocardiography. The equivalent costs for clinically significant CHD are £1,489 and £36,013, respectively. Key determinants of cost-effectiveness are detection rates and screening test costs. The false-positive rate is very high with screening echocardiography (5.4 percent), but lower with pulse oximetry (1.3 percent) or clinical examination alone (.5 percent).Conclusions: Adding pulse oximetry to clinical examination is likely to be a cost-effective newborn screening strategy for CHD, but further research is required before this policy can be recommended. Screening echocardiography is unlikely to be cost-effective, unless the detection of all clinically significant CHD is considered beneficial and a 5 percent false-positive rate acceptable.

Abstract
AIMS To assess what proportion of all cardiac abnormality can be suspected at birth when all clinical examination before discharge is undertaken by a small stable team of clinicians. METHODS A prospective audit of all the 14 572 births in a maternity unit only staffed by nurse practitioners between 1996 and 2003. RESULTS 1.2% of all babies born in the unit were found to have a structural defect (as confirmed by echocardiography) within a year of birth. The number not suspected before discharge declined over time, and only 6% were first suspected after discharge in the last four years of this eight year study. Four potentially life threatening conditions initially went unsuspected in 1996-8, but none after that. A policy of referring every term baby with a murmur at 1 day of age that was still present at 7-10 days resulted in 4.2% requiring cardiac referral; 54% of these babies still had a murmur when assessed one to two weeks later, and 33% had a structural defect. Parents said in independent, retrospectively conducted, interviews that they found it confidence building to have any possible heart defect identified early and the cause of any murmur clearly and authoritatively explained. CONCLUSIONS Effective screening requires experience and a clear, structured, referral pathway, but can work much better than most previous reports suggest. Whether staff bring a medical or nursing background to the task may well be of less importance.

Abstract
UNLABELLED Approximately half of all newborns with congenital heart disease are asymptomatic in the first few days of life. Early detection of ductal-dependant cardiac malformations prior to ductal closure is, however, of significant clinical importance, as the treatment outcome is related to the time of diagnosis. Pulse oximetry has been proposed for early detection of congenital heart disease. The aims of the present study were: 1) to determine the effectiveness of a pulse-oximetric screening performed on the first day of life for the detection of congenital heart disease in otherwise healthy newborns and 2) to determine if a pulse-oximetric screening combined with clinical examination is superior in the diagnosis of congenital heart disease to clinical examination alone. This is a prospective, multi-centre study. Postductal pulse oximetry was performed between six and twelve hours of age in all newborns of greater than 35 weeks gestation. If pulse-oximetry-measured arterial oxygen saturation was less than 95%, echocardiography was performed. Pulse oximetry was performed in 3,262 newborns. Twenty-four infants (0.7%) had repeated saturations of less than 95%. Of these infants, 17 had congenital heart disease and five of the remaining seven had persistent pulmonary hypertension. No infant with a ductal-dependant or cyanotic congenital heart disease exhibited saturation values greater or equal to 95%. CONCLUSION postductal pulse-oximetric screening in the first few days of life is an effective means for detecting cyanotic congenital heart disease in otherwise healthy newborns.

Abstract
OBJECTIVES To estimate the incidence of, and profile the spread of, congenital cardiac defects, and to assess the accuracy of the echocardiographic diagnosis as performed by a neonatologist. DESIGN Hospital-based study. METHODS All neonates meeting our criterions, specifically those with a persistent murmur 48 hours after birth, underwent an echocardiographic examination to exclude an underlying congenital cardiac defect. All scans performed by the neonatologist were videotaped and reviewed by a paediatric cardiologist. We assessed concordance according to inter-rater agreement. RESULTS Out of 11,085 live births, there were 83 infants with a congenital cardiac defect, giving an incidence of 7.49 per 1000 live births, with 95% confidence interval from 5.88 to 9.09. Of the infants with a murmur persisting at or greater than 48 hours after birth, who had a median age of 4.5 days, 75% had a congenital heart defect, with ventricular septal defect being the commonest, encountered in 56.7% of cases. Concordance between the neonatologist and the cardiologist was good, with Cohen's Kappa coefficient being calculated at 0.68, and 95% confidence interval from 0.51 to 0.85. CONCLUSION The incidence of congenital cardiac malformations as determined in our hospital-based study in the United Arab Emirates is similar to that described in the Gulf region and worldwide. A persistent murmur at or greater than 48 hours after birth is strongly suggestive of an underlying congenital cardiac malformation. Our experience shows that a neonatologist appropriately trained in echocardiography can perform as well as a paediatric cardiologist. Where specialist resources are limited, this allows for early diagnosis, earlier referral if necessary, and early institution of appropriate therapy.

Abstract
OBJECTIVES Midwives have been actively involved in the clinical teaching of medical students for many years. However, this role has received little attention and limited research has been conducted into either its efficacy or the development of strategies to maximise the potential of such teaching opportunities. We examined medical student and midwifery preceptor attitudes towards students' learning objectives during the labour ward placement. METHODS A descriptive cross-sectional survey of midwifery preceptors and medical students was undertaken. The setting was an Australian teaching and tertiary referral hospital. The questionnaire contained questions about strategies to improve medical student involvement on the labour ward and opinions towards core competencies of the student curriculum. RESULTS Of 94 questionnaires issued to midwifery preceptors, 63 were returned (response rate 67%). Of 130 questionnaires issued to medical students, 93 were returned (response rate 72%). Major differences in the expectations of students and midwifery preceptors were identified. Only 17% of midwives felt medical students should be involved in helping mothers with breastfeeding, and some no longer saw a role for students in delivering babies or performing well baby checks. These differences in opinions led to student dissatisfaction with their obstetric learning experience. CONCLUSION Educators need to ensure that students and midwifery preceptors identify common learning objectives. Failure to address these differences may lead to poor interdisciplinary relationships.

Abstract
Peripheral pulmonary artery stenosis challenges therapeutic algorithms for the management of congenital heart malformations. Surgical repair of the proximal pulmonary artery lesion remains with a high recurrence rate while the distal lesions are difficult to access. With the development of transcatheter interventional strategies in the early 1980s, a number of transcatheter treatment options became available. In this review, we summarize the current state of the art for interventional strategies in the management of peripheral pulmonary artery stenosis.

Abstract
AIM To show that, given appropriate guidelines, senior house officers (SHOs) have the clinical skills required to assess neonatal murmurs. METHODS Neonatal SHOs identified babies with a cardiac murmur at routine neonatal examination. The SHOs assessed whether the murmur was significant or innocent and decided between immediate further assessment or echocardiogram as an outpatient. RESULTS A total of 112 babies had murmurs at routine neonatal examination. The incidence of cardiac murmurs was 13.8 per 1000. Twelve babies were referred for immediate further assessment. Eleven had structurally abnormal hearts. One had a normal heart with pulmonary hypoplasia. One hundred babies were referred, and 78 attended for outpatient follow up. Of these, the SHO assessed nine babies as having a significant murmur and 69 as having an innocent murmur. Twenty two babies failed to attend for follow up; all were thought to have innocent murmurs. Of the nine murmurs assessed as significant, four were confirmed as such and five were found to be innocent. Of the 91 murmurs assessed as innocent, 63 were proven to be innocent, six had abnormalities on echocardiogram, and 22 defaulted to follow up. Five of the serious murmurs were small ventricular septal defects, which had resolved by 6 months of age; the other had mild pulmonary stenosis. None of these babies were clinically symptomatic at outpatient review. CONCLUSION Given appropriate guidelines, SHOs have the skills to assess the significance of, and decide on appropriate management for, neonatal murmurs. Electrocardiograms and chest radiographs are not necessary.

Abstract
AIMS To define how often transient pulmonary branch stenosis (PBS) develops after closure of a patent ductus arteriosus (PDA) in babies born at less than 32 weeks gestation; to describe the natural history of PBS and the relation between PBS and a cardiac murmur. METHODS Fifty three preterm infants born at a gestational age less than 32 weeks and who had PDA diagnosed on echocardiography were recruited. An echocardiogram was performed on alternate days until the ductus arteriosus closed. If PBS was diagnosed, the baby was followed up until PBS resolved. RESULTS In 59%, PBS developed in one or both branches after closure of the PDA. In 21%, both pulmonary branches were affected. In 79%, the left pulmonary artery alone was involved but the right side was never affected alone. PBS had resolved in 74% by the time the infants reached 40 weeks, in 95% at a corrected age of 6 weeks, and in 100% at a corrected age of 3 months. There is a better correlation between a cardiac murmur and PBS than between a murmur and PDA. CONCLUSIONS PBS in preterm infants is usually not present at birth but develops after closure of a PDA. PBS resolves by a corrected age of 3 months. The presence of a murmur after closure of a PDA is usually related to PBS and not to reopening of the ductus arteriosus.

Abstract
BACKGROUND Pulmonary arterial branch stenosis (PBS) in neonates is considered to be transient. However, PBS has been found not only in neonates, but also in young infants. Among these patients, we encountered several patients whose PBS was still present after the age of 1 year. METHODS To clarify the natural history of PBS in neonates and young infants, we retrospectively reviewed the records of 103 patients diagnosed with PBS in the neonatal period and early infancy. RESULTS The PBS findings were improved in all patients. Pulmonary arterial branch stenosis disappeared in 94 patients by the age of 1 year (group A), but persisted after I year of age in nine patients (group B). Group B patients had a significantly lower mean birth weight and greater deltavelocity (the difference in the peak flow velocity between the main pulmonary artery and stenotic branch) at diagnosis than group A patients. Incidences of low birth weight (< 2,500 g) and deltavelocity above 1.2 m/s were significantly higher in group B than group A patients. There was no significant difference in the frequency of premature infants (gestational age < 36 weeks) between the groups, suggesting that intrauterine growth retardation may be related to developmental abnormalities of the pulmonary arterial branch. CONCLUSIONS All cases of PBS in neonates and young infants were improved. However, PBS persisted in some patients after the age of 1 year. Low birth weight and deltavelocity above 1.2 m/s are risk factors for persistent PBS. Pulmonary arterial branch stenosis was not present after the age of 1 year in 62 of 63 patients without either of these risk factors.

Abstract
Routine examination of apparently healthy newborn babies detects less than half of those with congenital cardiac malformations because they are asymptomatic and without signs. More severe cardiac malformations are not detected more easily. A normal clinical examination does not exclude serious congenital cardiac malformation. Left heart obstruction is easily overlooked but often causes serious deterioration in less than 3 weeks. It is important to arrange early echocardiography of babies with signs and to consider cardiac malformation in a sick baby even if a previous routine examination was normal. All babies with Down syndrome should have early expert cardiological assessment.

Abstract
OBJECTIVE To investigate the diagnostic value of the physical examination and electrocardiogram in the evaluation of heart murmur in new patients referred to the pediatric cardiologist. METHOD From 1 April to 30 September 1998, all consecutive patients referred to the pediatric cardiology clinic for evaluation of heart murmur were included. They were prospectively categorized with no heart disease, possible heart disease or definite heart disease based on history and physical examination. They then underwent electrocardiogram with which the diagnosis was reevaluated by the pediatric cardiologist. Lastly, a doppler-echocardiography was systematically performed. RESULTS In 120 children aged four days to 14 years (median: ten months), 72 (60%) showed abnormalities on doppler-echocardiography and 48 (40%) no heart disease. After physical examination, 52 patients were categorized with no heart disease: 45 patients had a normal doppler-echocardiography; in three of them, the diagnosis was incorrectly modified to possible heart disease on the basis of the electrocardiogram. In the other seven children, the electrocardiogram was normal and the doppler-echocardiography revealed minor (n = 5) or moderate (n = 2) heart defects. Nineteen patients were suspected of having possible heart disease, no diagnosis was modified after analysis of the electrocardiogram and six had normal doppler-echocardiography; 49 patients were correctly diagnosed as having definite heart disease. The sensibility of the physical examination was 90.3%, the specificity was 93.8%, the positive predictive value 95.6% and the negative predictive value 86.5%. CONCLUSION The electrocardiogram is of no help in the discrimination between heart disease and no heart disease in children referred to the pediatric cardiologist for a cardiac murmur. The physical examination is able to differentiate children with or without heart disease in most of the cases.

Abstract
BACKGROUND Gulf War veterans (GWVs) have expressed concern about possible teratogenic exposures. However, epidemiologic studies on birth defects prevalence among their progeny have been limited to military hospitals, anomalies diagnosed among newborns, or self-reported data. To measure the prevalence of selected birth defects among infants of GWVs and nondeployed veterans (NDVs) in Hawaii, using birth defects surveillance records. METHODS Personal identifiers of 684,645 GWVs and 1,587,102 NDVs and their families were matched against birth certificate records of 99,545 live births reported to the State of Hawaii Department of Health between 1989 and 1993 to identify births to military personnel. These births were matched with records from the Hawaii Birth Defects Program. RESULTS A total of 17,182 military infants (3,717 GWV infants and 13,465 NDV infants) were identified. Of these, 367 infants (2.14/100 live births) were identified with one or more of 48 major birth defects diagnoses. The prevalence of the 48 birth defects were similar for GWV and NDV infants during the prewar and postwar periods, and among GWV infants who were conceived before and after the Gulf war. CONCLUSIONS The results must be interpreted with caution because of the small number of affected infants in each birth defects category. This study demonstrated the feasibility of measuring birth defects prevalence among military infants through multiple data linkage. Further, it included live births to parents who had separated from the military, births in civilian hospitals, and birth defects diagnosed through the first year of life.

Abstract
AIM To determine the prevalence and clinical significance of murmurs detected during routine neonatal examination. METHODS In a two year prospective study, 7204 newborn babies underwent routine examination by senior house officers. All those with murmurs underwent echocardiographic examination. All babies presenting later in infancy were also identified, to ascertain the total prevalence of congenital heart disease in infancy. RESULTS Murmurs were detected in 46 babies (0.6%) of whom 25 had a cardiac malformation. The most common diagnosis was a ventricular septal defect, although four babies had asymptomatic left heart outflow obstruction. A further 32 infants from the same birth cohort had a normal neonatal examination but were found to have a cardiac malformation before 12 months of age. CONCLUSIONS The neonatal examination detects only 44% of cardiac malformations which present in infancy. If a murmur is heard there is a 54% chance of there being an underlying cardiac malformation. Parents and professionals should be aware that a normal neonatal examination does not preclude a clinically significant cardiac malformation. The detection of a murmur should prompt early referral to a paediatric cardiologist for diagnosis or appropriate reassurance.
