RESUMEN
BACKGROUND: Japanese Kawasaki disease (KD) risk scores cannot be adopted in non-Japanese patients. In North American populations a baseline coronary artery Z-score > 2 and the Son score are associated with coronary artery aneurysms (CAAs) at 4 and 8 weeks from disease onset. In European populations, the Kawanet and Kawanet-echo scores are associated with intravenous immunoglobulin resistance. This study aims to evaluate the association between KD risk scores and baseline coronary artery Z-scores with CAAs at one, two, and six months in a European population. METHODS: Historical cohort study of all the children diagnosed with KD in a tertiary care hospital in Milan, Italy, between 1st January 2015 and 31st May 2021. Univariate and multivariate (adjusting for age and corticosteroid therapy) logistic regression analyses were used to study the association between the risk scores, a baseline Z-score ≥ 2 and ≥ 2.5 with CAAs. RESULTS: Eighty-nine patients were diagnosed with KD at our Centre, and 12 were excluded based on the exclusion criteria. We included 77 patients, 51 (66%) males, and 26 (34%) females, with a median age at presentation of 27 months (IQR 13-46). A baseline Z-score ≥ 2 was correlated with CAAs at one and two-month follow-ups (odds ratio (OR) 10, 95% confidence interval (CI) 2-72, and OR 18, CI 3-357) but not at six-month follow-up. The Son score showed an association with one and two-month follow-up CAAs (OR 3, CI 1.3-7, and OR 3, CI 1.3-8) but not with a six-month follow-up. CONCLUSIONS: Patients with a baseline Z-score ≥ 2 are at higher risk for CAAs in the long term. The Son score should be tested in larger European samples. Further studies should keep the observational periods longer than 8 weeks from KD onset.

INTRODUCTION: The persistent patency of the ductus arteriosus frequently occurs in premature neonates and can cause infective endocarditis (IE) or ductal endarteritis (DE) during sepsis. Even though neonatal IE and DE are believed to be a rare eventuality, their incidence has been increasing in the last decades due to the improved survival of even more preterm babies, favored by highly invasive procedures and therapies. In parallel, antimicrobial resistance is another rising problem in neonatal intensive care units, which frequently compels to treat infections with broad-spectrum or last generation antibiotics. CASE PRESENTATION: We report the case of a preterm neonate affected by patent ductus arteriosus-associated DE that followed an episode of sepsis caused by a high-level aminoglycoside-resistant enterococcus. The neonate was successfully treated with the synergistic combination of ampicillin and cefotaxime. DISCUSSION: IE and patent ductus arteriosus-associated DE are rising inside neonatal intensive care units and neonatologists should be aware of these conditions. Enterococcal IE and patent ductus arteriosus-associated DE sustained by high-level aminoglycoside-resistant strains can be successfully treated with the synergistic combination of ampicillin and cefotaxime even in preterm neonates.

Cornelia de Lange syndrome (CdLS) is a rare multisystem congenital neurodevelopmental disorder (NDD) characterized by distinctive facial anomalies, short stature, developmental delay, hirsutism, gastrointestinal abnormalities and upper limb reduction defects. CdLS syndrome is associated with causative variants in genes encoding for the cohesin complex, a cellular machinery involved in chromatid pairing, DNA repair and gene-expression regulation. In this report, we describe a familial case of a syndromic presentation in a 4-year-old patient (P1) and in his mother (P2). Trio-based Whole Exome Sequencing (WES) performed on P1 was first negative. Since his phenotypic evolution during the follow-up was reminiscent of the CdLS spectrum, a reanalysis of WES data, focused on CdLS-related genes, was requested. Although no alterations in those genes was detected, we identified the likely pathogenetic variant c.40G > A (p.Glu14Lys) in the PHIP gene, in the meanwhile associated with Chung-Jansen syndrome. Reverse phenotyping carried out in both patients confirmed the molecular diagnosis. CHUJANS belongs to NDDs, featuring developmental delay, mild-to-moderate intellectual disability, behavioral problems, obesity and facial dysmorphisms. Moreover, as here described, CHUJANS shows a significant overlap with the CdLS spectrum, with specific regard to facial gestalt. On the basis of our findings, we suggest to include PHIP among genes routinely analyzed in patients belonging to the CdLS spectrum.

Cor triatriatum dexter (CTD) is an extremely uncommon and underreported congenital cardiac anomaly in which the persistence of the embryonic right venous valve separates the right atrium into two chambers with varying degrees of obstruction to antegrade flow and variable degree of right to left shunt at atrial level. Depending on the size of the valves, clinical manifestations vary from absence of symptoms to severe hypoxia, requiring urgent surgical correction. We herein describe the diagnostic difficulties in a case of neonatal CTD, who developed increasingly severe and unresponsive cyanosis, first interpreted as postnatal maladjustment with pulmonary hypertension. The failure to respond to oxygen and pulmonary vasodilators led us to reconsider a different diagnosis. The use of contrast echocardiography improved the diagnostic performance of transthoracic echocardiogram (TTE) and revealed a massive right-to-left shunt secondary to the presence of an atrial membrane that required urgent surgery.
RESUMEN
Sonographic findings of cerebral arteriovenous malformations in the fetus are uncommon and usually regard aneurysm of the Galen vein. Outcome of arteriovenous malformations is usually severe. We report a case of a fetus at 21 weeks' gestation with a rarer arteriovenous malformation, referred to us for echocardiography on account of a suspicious cardiomegaly at obstetrical scan. Upon examination, we found cardiomegaly, together with an associated moderate tricuspid regurgitation, however, there were no clear features of tricuspid dysplasia. Considering an unusually dilated superior vena cava, we found via color Doppler imaging a systodiastolic flow at Color Doppler progressing. Subsequent MRI of the central nervous system determined the localization in the sinus dura mater. Due to an already evident hemodynamic impact, the parents opted for the termination of the pregnancy. Autopsy confirmed a voluminous arteriovenous malformation of the transverse sinus of the dura mater, severe cardiomegaly, mainly of the ventricles, and hypoplasia of the lungs.
RESUMEN
Congenital diaphragmatic hernia is a rare disease with high mortality and morbidity due to pulmonary hypoplasia and pulmonary hypertension. The aim of the study is to investigate the relationship between radiographic lung area and systolic pulmonary artery pressure (sPAP) on the first day of life, mortality, and hernia recurrence during the first year of life in infants with a congenital diaphragmatic hernia (CDH). A retrospective data collection was performed on 77 CDH newborns. Echocardiographic sPAP value, deaths, and recurrence cases were recorded. Lung area was calculated by tracing the lung's perimeter, excluding mediastinal structures, and herniated organs, on the preoperative chest X-ray performed within 24 h after birth. Logistic and linear regression analyses were performed. Deceased infants showed lower areas and higher sPAP values. One square centimeter of rising in the total, ipsilateral, and contralateral area was associated with a 22, 43, and 24% reduction in mortality risk. sPAP values showed a decreasing trend after birth, with a maximum of 1.84 mmHg reduction per unitary increment in the ipsilateral area at birth. Recurrence patients showed lower areas, with recurrence risk decreasing by 14 and 29% per unit increment of the total and ipsilateral area. In CDH patients, low lung area at birth reflects impaired lung development and defect size, being associated with increased sPAP values, mortality, and recurrence risk. Clinical Trial Registration: The manuscript is an exploratory secondary analysis of the trial registered at ClinicalTrials.gov with identifier NCT04396028.
RESUMEN
BACKGROUND: Sustained fetal supraventricular tachycardia is a potentially life-threatening disorder and is usually treated by administering antiarrhythmia drugs to the mother, which can require at least 48-72 hours to achieve normal sinus rhythm. In neonates with supraventricular tachycardia, first-line treatment is stimulation of the vagus nerve to elicit the diving reflex, commonly by application of a cold pack to the face, with a high, albeit sometimes temporary, success rate. CASE: We describe a case of fetal supraventricular tachycardia at term treated successfully by eliciting the diving reflex with an ice pack to the maternal abdomen over the lower uterine segment. The neonate was given propranolol augmented with flecainide because of recurrent supraventricular tachycardia. He remained in a stable sinus rhythm without side effects 5 months later. CONCLUSIONS: Cardioversion of fetal supraventricular tachycardia at term by eliciting the diving reflex could be offered to allow normal labor and vaginal delivery.

OBJECTIVE: By the end of February 2020, the COVID-19 pandemic infection had spread in Northern Italy, with thousands of patients infected. In Lombardy, the most affected area, the majority of public and private hospitals were dedicated to caring for COVID-19 patients and were organized following the 'Hub-and-Spoke' model for other medical specialties, like cardiac surgery and interventional procedures for congenital cardiac disease (CHD). Here, we report how the congenital cardiac care system was modified in Lombardy and the first results of this organization. METHODS: We describe a modified 'Hub-and-Spoke' model - that involves 59 birthplaces and three specialized Congenital Cardiac Centers -- and how the hub center organized his activity. We also reported the data of the consecutive cases hospitalized during this period. RESULTS: From 9 March to 15 April, we performed: a total of 21 cardiac surgeries, 4 diagnostic catheterizations, 3 CT scans, and 2 CMR. In three cases with prenatal diagnosis, the birth was scheduled. The spoke centers referred to our center six congenital cardiac cases. The postop ExtraCorporeal Membrane Oxygenation support was required in two cases; one case died. None of these patients nor their parents or accompanying person was found to be COVID-19-positive; 2 pediatric intensivists were found to be COVID-19-positive, and needed hospitalization without mechanical ventilation; 13 nurses had positive COVID swabs (4 with symptoms), and were managed and isolated at home. CONCLUSION: Our preliminary data suggest that the model adopted met the immediate needs with a good outcome without increased mortality, nor COVID-19 exposure for the patients who underwent procedures.

Incidental azygos vein cannulation has been reported in a few cases of neonatal extracorporeal membrane oxygenation (ECMO). This complication is described in the literature mainly in pathological conditions wherein increased central venous pressure dilates the superior vena cava (SVC), i.e., right congenital diaphragmatic hernia (CDH) or pulmonary hypertension. Azygos vein cannulation should always be suspected in cases of impaired venous return and circuit failure. Although rare, it hinders proper venous aspiration of the ECMO circuit and generally requires repositioning or replacement of the venous cannula or conversion to central cannulation. In this report, we describe a newborn with severe right CDH who required ECMO assistance, wherein incidental cannulation of the azygos vein resulted in successful functioning of the circuit because of the concomitant presence of isolated interruption of the inferior vena cava and azygos continuation. To the best of our knowledge, this is the first report of successful neonatal ECMO despite azygos vein cannulation in a patient with such rare physiology.
RESUMEN
We describe the echocardiographic finding of a 35-year-old pregnant woman, referred for a clinical consultation at our institution because of congestive heart failure. She underwent echocardiography with only little information about a history of cardiac surgery during infancy. At the first sight, parasternal long axis view demonstrates normal structures, but on the apical view we diagnosed a very rare condition with typical imaging findings: Criss Cross heart.

Propranolol is becoming the treatment of choice for complicated infantile hemangioma. We report here data on peripheral blood flow, O2-saturation, electrocardiographic PR-interval, left ventricular function, blood pressure and heart rate that were assessed before and during treatment for ≥4 weeks with propranolol 2 mg/kg of body weight daily in 67 infants <12 months of age in normal sinus rhythm and with structurally normal hearts. Management with propranolol was well tolerated in all and did not modify peripheral blood flow, O2-saturation, electrocardiographic PR-interval and left ventricular fractional shortening or ejection fraction. Absolute blood pressure levels were similar without and with propranolol. However, age-adjusted centile levels for both systolic and diastolic levels were significantly lower while on propranolol. The heart rate was significantly lower both when expressed as absolute value and when expressed as age-adjusted centile on treatment with propranolol. In conclusion, propranolol 2 mg/kg of body weight daily causes a statistically though not clinically relevant decrease in blood pressure and heart rate in cardially healthy infants affected by infantile hemangioma. Temporary discontinuation during acute febrile illnesses and during diarrheal diseases should be considered to prevent excessive hypotension.

BACKGROUND AND OBJECTIVES: Information on ambulatory blood pressure monitoring (ABPM) in children is scarce. While in adults office BP (OBP) is higher than ABP and the difference increases as OBP increases, information in children suggests that at this young age ABP is no lower and often higher than OBP. This study was aimed at describing OBP-ABP differences in a cohort of children of different ages and BPs, and investigating whether OBP-ABP differences are dependent on age or OBP level. METHODS: We retrospectively compared OBP and 24-h, daytime and night-time ABP in 433 children and adolescents aged 4-18 years, referred to our hospital clinic. RESULTS: OBP was found to be significantly lower than 24-h and daytime ABP in the low age tertile (4-10 years) but not in the medium and high tertiles. OBP was also lower than ABP in normotensive patients (nâ=â182), but higher than ABP in untreated hypertensive patients (nâ=â92) despite similar ages. Continuous analyses showed a weak correlation of OBP-ABP differences with age, and a much stronger correlation with OBP so that 24-h ABP was higher than OBP at OBP values less than 117/73âmmHg and lower than OBP at higher OBP values. Logistic regression analysis indicates that also in children OBP accounts for most of the OBP-ABP difference. CONCLUSION: There is a common relation both in children and adults between OBP and ABP. It is only because high OBP is common in the elderly, and the lowest OBP is usually found in young children that large positive OBP-ABP differences have been associated with old age, and negative differences with childhood. OBP-ABP differences, often defined as white-coat effect, can have different directions and are likely to be largely due to regression to the mean.

Williams-Beuren syndrome (WBS) is a multisystem disorder that requires ongoing management by a primary care physician familiar with the natural history and specific medical problems associated with the condition. While the natural history of the disease during infancy is well known, data about the adult WBS population have been published only in the last few years, and show a wide range of medical, neurological, and psychiatric problems. We investigated 45 young adult WBS patients (mean age 23 years, range 17-39 years) using a well-coordinated team which included a cardiologist, a nephrologist, an ophthalmologist, an endocrinologist, a gastroenterologist, orthodontist, and orthopedist. Here we describe the clinical features and medical complications in this cohort of patients. Most patients demonstrated a high frequency of multiple organ systems complications, in particular, abnormal body habitus; cardiovascular disease, and hypertension; sensorineural hearing loss; gastrointestinal symptoms including diverticular disease and abnormal glucose tolerance. We offer some suggestions for clinical monitoring which we propose will be useful in the overall care of adults with WBS.

Congenital heart defects (CHDs) have been estimated to occur in approximately 20% of patients with Brachmann-de Lange syndrome (BDLS, also known as Cornelia de Lange syndrome, OMIM 122470). We report on the results of a prospective echocardiographic evaluation of a cohort of 87 Italian BDLS patients with longitudinal follow-up from 5 to 12 years. A cardiac anomaly was identified in 29/87 (33.3%) including 28 (32.2%) patients with a structural CHD, and an additional patient (1.2%) with isolated non-obstructive hypertrophic cardiomyopathy (HCM). Of the 28 patients with a CHD, 12 (42.9%) had an isolated obstructive CHD, 10 of which were pulmonary stenosis (36%), 8 (28.6%) had an isolated left to right shunt, and the remainder showed a combination of structural anomalies. Overall incidence of pulmonary stenosis was 39% (11/28). Isolated late-onset mitral or tricuspid valve dysplasia, albeit hemodynamically insignificant, was detected at follow-up examination in 4 (14.3%) patients older than 10 years, previously known to be normal. In contrast to previous studies, only two patients required surgery, one for closure of a large perimembranous ventricular septal defect (VSD) and associated ASD closure (1), and another for VSD closure and relief of pulmonary valve stenosis (1). The remainder are receiving medical follow-up. We believe that the overall frequency (33.3%) and evidence of 4 late onset dysplastic valves anomalies justifies both echocardiographic assessment in all BDLS patients at the first diagnostic assessment, and later on during medical follow-up.

BACKGROUND: Flecainide for the treatment of supraventricular tachycardia (SVT) in newborns is still controversial because of its potentially severe proarrhythmic effects. METHODS AND RESULTS: Between January 2004 and December 2006, we used flecainide to treat 20 consecutive newborns (15 males) with paroxysmal SVT without any structural heart disease. Their age at hospitalization was 11.5 +/- 11.1 days. The intravenous administration of flecainide (1 mg/kg) effectively restored sinus rhythm in all the patients. Once stable sinus rhythm had been restored, the drug was administered orally at a dose of 2 mg/kg/day twice daily, which was uptitrated as the patients gained weight. The patients were followed up for up to 24 months with clinical evaluations, baseline ECG and 24-h Holter monitoring every 3 months. There were neither deaths nor any episodes of heart failure or sustained ventricular tachycardia during follow-up. SVT were completely controlled in 17 patients (85%), with an oral dose of 3.35 +/- 1.35 mg/kg/day of flecainide; in the remaining three patients with refractory arrhythmias, propranolol was added for optimal treatment. No significant increase in the duration of QRS (70 +/- 1.09 vs. 63.8 +/- 1.87 ms, P = NS) or any significant QTc prolongation (413 +/- 7.4 vs. 412.6 +/- 8.01 ms, P = NS) was observed. One patient developed an incomplete right bundle branch block promptly reverted by reducing the dose. CONCLUSION: This preliminary experience indicates that flecainide is well tolerated and effective as first-line treatment for paroxysmal SVT in newborns without structural heart disease.
