Diagnostic Value of Tc-MIBI Myocardial Perfusion Imaging in Detecting Myocardial Ischemia of Children with Kawasaki Disease and Coronary Artery Lesions.

Pediatric patients with coronary artery lesions (CALs) after Kawasaki disease (KD) may be complicated with myocardial ischemia. Although previous studies in adults have proven the diagnostic value of Tc-MIBI myocardial perfusion imaging (MPI) for ischemic heart disease, its feasibility and accuracy in this pediatric population remain uncertain. In this retrospective study, we collected data of 177 pediatric patients (Age range: 6 months to 14 years) who had undergone MPI and coronary artery angiography (CAG) between July 2019 and February 2023.

Temporal trend in mortality due to congenital heart disease in China from 2008 to 2021.

Background: Congenital heart disease (CHD) is a leading cause of birth defect-related mortality. However, more recent CHD mortality data for China are lacking. Additionally, limited studies have evaluated sex, rural-urban, and region-specific disparities of CHD mortality in China.

Impact of Newborn Screening Programme for Congenital Heart Disease in Shanghai: a five-year observational study in 801,831 newborns.

Background: Newborn Screening Programme for Congenital Heart Disease (CHD) in Shanghai has been in operation for over 5 years, and its feasibility and effectiveness still lack a systematic and comprehensive evaluation. This study aimed to detail the implementation of the programme and evaluate its results, benefits, and reliability in clinical practice.

Methods: This study was an observational study involving all newborns received CHD screening in Shanghai from 2017 to 2021.

Pediatric bronchial Dieulafoy's disease with bronchial artery embolization: two case reports.

Background: Bronchial Dieulafoy's disease (BDD) is a vascular malformation characterized by the presence of a dysplastic artery in the bronchial submucosa. It is very rare in children but potentially fatal due to life-threatening hemoptysis.

Case Description: An 8-year-old boy and a 6-year-old girl were referred to our hospital with recurrent moderate to massive hemoptysis.

Trajectories of oxygen saturation within 6-72 hours after birth in neonates at moderate altitude: a prospective longitudinal cohort study.

Background: Trajectories of pulse oxygen saturation (SpO) within the first few days after birth are important to inform the strategy for identifying asymptomatic hypoxemic disease but remain poorly substantiated at higher altitudes.

Methods: We performed a longitudinal cohort study with consecutive neonates at a local hospital in Luchun County, China, at an altitude of 1650 m between January and July 2020. We repeatedly measured the pre- and post-ductal SpO values at 6, 12, 18, 24, 36, 48, and 72 hours after birth for neonates without oxygen supplements.

Peripheral perfusion index in well newborns at 6 to 72 h of life at different altitudes: a multi-center study in China.

The purpose of this study is to obtain the reference range of peripheral perfusion index (PPI) of asymptomatic well newborns at 6 to 72 h of life at different altitudes. A population-based prospective cohort study was conducted in cities at different altitudes in China. Asymptomatic well newborns were enrolled consecutively from six hospitals with an altitude of 4 to 4200 m between February 1, 2020, and April 15, 2021.

Mid-aortic syndrome: a rare cause of heart failure in infants.

This case reports describe a rare disease, mid-aortic syndrome (MAS), that can cause severe heart failure and hypertension in infancy. The typical images, key points of diagnosis, and therapy methods of the disease have also been presented. We report two critical thoracoabdominal aortic coarctation cases in infants aged 2 and 11 months with severe heart failure.

Case Report: Recurrent Left Posterior Fascicular Ventricular Tachycardia in a Newborn.

Left posterior fascicular ventricular tachycardia (LPFVT) is extremely rare in neonates. We described a 17-day-old girl with LPFVT who was initially misdiagnosed as supraventricular tachycardia (SVT). Eventually, she was successfully treated by amiodarone infusion followed by oral amiodarone with propranolol for 9 months, and LPFVT spontaneously resolved after a 1-year follow-up.

Case Report: Lessons Learned From Aortic Valve Rupture After Blunt Chest Trauma.

Aortic valve rupture (AVR) due to blunt chest trauma is extremely rare in the pediatric population, and little attention has been paid to such damages. Early diagnosis of AVR may not be easy in patients with multiple competing injuries and poor acoustic windows. We report a case of delayed diagnosis of AVR in a 12-year-old boy after falling from a height of 15 meters, who presented with recurrent hemoptysis and ventilator dependence.

Randomized trial of different initial intravenous immunoglobulin regimens in Kawasaki disease.

Background: We aimed to assess the efficacy of different initial intravenous immunoglobulin (IVIG) regimens in Kawasaki disease (KD) patients to find more cost-effective therapy options.

Methods: A multicenter, open-label, blind-endpoint randomized controlled trial was conducted from January 2014 to December 2015. Patients with KD, within 10 days of illness, were randomly assigned to receive different IVIG regimens (Group A, 2 g/kg once; Group B, 1 g/kg for 2 consecutive days; Group C, 1 g/kg once) and aspirin 30mg/kg/d.

Characteristics and trends in diagnosis of Kawasaki disease outside the usual age range.

Objective: To explore the trends in diagnosis of Kawasaki disease (KD) and determine the characteristics for patients outside the usual age range of 6 months to 4 years.

Method: A retrospective review of patients with KD identified in four epidemiological surveys spanning 20 years (1998-2017) in Shanghai was performed.

Results: A total of 8416 patients were included.

Neonatal Kawasaki disease with multiple arterial aneurysms: a case report.

Background: Kawasaki disease (KD) is a medium vessel vasculitis that typically occurs in children aged between 6 months and 5 years. It is extraordinarily rare in the neonatal period. KD-related systemic artery aneurysms (SAAs) have never been reported in neonates.

Bronchial Artery Embolization in Pediatric Pulmonary Hemorrhage: A Single-Center Experience.

Peripheral perfusion index percentiles for healthy newborns by gestational age and sex in China.

Peripheral perfusion index (PPI) percentiles for newborns serve as an important observation tool in clinical practice, but research pertaining to reference ranges are lacking. The aim of this study was to establish PPI percentiles for healthy newborns by gestational age and sex at 24-48 hours of life. We conducted an observational study and examined PPI values at 24-48 hours of life in 3814 asymptomatic newborns born between 35 and 41 weeks gestation who did not need medical treatment from June 1, 2016 to May 31, 2017 at two maternity hospitals in Shanghai.

Systemic Artery Aneurysms and Kawasaki Disease.

Background: Coronary artery aneurysms (CAAs) are a well-known complication of Kawasaki disease (KD), but there are no data on incidence or outcomes of systemic artery aneurysms (SAAs) in the current era.

Methods: From April 1, 2016, to March 31, 2019, we screened for SAAs in 162 patients with KD at risk for SAAs with magnetic resonance angiography or peripheral angiography and analyzed incidence and early outcomes of SAAs.

Results: Twenty-three patients had SAAs, demonstrating an incidence of 14.

Apical hypertrophic cardiomyopathy: an uncommon cause of exertional chest pain in children.

Apical hypertrophic cardiomyopathy is an uncommon morphologic variant of hypertrophic cardiomyopathy, which is rarely diagnosed in childhood. To date, very few cases of asymptomatic children younger than 18 years have been reported in the literature. To the best of our knowledge, this is the first case of paediatric apical hypertrophic cardiomyopathy presenting with exertional chest pain, with characteristic electrocardiographic, echocardiographic, MRI, and cardiac angiography findings.

Spontaneous Closure Rates of Ventricular Septal Defects (6,750 Consecutive Neonates).

Although ventricular septal defect (VSD) is a common and simple congenital heart disease in newborns, its true incidence and spontaneous closure (SC) rate remains topics of controversy. This study aims to provide data on the true incidence and SC rate of VSD in the Chinese neonatal population. We conducted a prospective study at 3 hospitals, all newborns underwent echocardiography.

Accuracy of cardiac auscultation in detection of neonatal congenital heart disease by general paediatricians.

Background: Challenges remain in the judgement of pathological murmurs in newborns at maternity hospitals, and there are still many simple major CHD patients in developing countries who are not diagnosed in a timely fashion. This study aimed to evaluate the accuracy of cardiac auscultation on neonatal CHD by general paediatricians.

Methods: We conducted a prospective study at three hospitals.
