    CASE REPORT

    2q37.3 Deletion with Complex Heart Defects Suggesting Interruption of Early Ventricular Looping

    Sanam Safi1,2, Takato Yamasaki1,3, David J. Glidden4, Stephen P. Sanders1,5, Chrystalle Katte Carreon1,6,*

    Congenital Heart Disease, Vol.17, No.2, pp. 141-146, 2022, DOI:10.32604/chd.2022.019743

    Abstract A maternally inherited 828 kb microdeletion of 2q37.3 manifested in a 3-week-old premature boy as left juxtaposition of the atrial appendages associated with tricuspid atresia, double outlet infundibulum, subvalvar pulmonary atresia, large secundum atrial septal defect, and right aortic arch with mirror-image branching, consistent with developmental arrest early in heart looping. To the best of our knowledge, no previous 2q37 deletion syndrome has been reported with such a severe cardiac dysmorphology. Hence, this case adds to the cardiac phenotypes identified in 2q37 deletion syndrome. More >

    Abstract Background: Repaired Tetralogy of Fallot (rTOF) patients may have residual lesions such as main (MPA) and branch pulmonary artery stenosis (BPAS). While MPA stenosis is well studied, few data are available on BPAS in rTOF. We aimed to describe pulmonary perfusion in a large paediatric cohort of rTOF and its impact on right ventricular and outflow-tract hemodynamics using 4D flow CMR. Methods: 130 consecutive patients (mean age at CMR 14.3 ± 4.6 years) were retrospectively reviewed. 96 patients had transannular patch without valve preservation while 34 patients had conserved annulus or valved conduit. A pulmonary blood flow ratio (right pulmonary artery (RPA)/left… More > Graphic Abstract

    Partial Anomalous Pulmonary Venous Connection and the Nature of Associated Sinus Venosus Defect

    Ling Sun1,#, Chengcheng Pang1,#, Xiaoyan Wang2,#, Mingguo Xu3, Zhiwei Zhang1,*, Shushui Wang1,*

    Congenital Heart Disease, Vol.17, No.2, pp. 201-214, 2022, DOI:10.32604/chd.2022.018453

    Abstract Background: Partial anomalous pulmonary venous connection (PAPVC) is frequently associated with atrial septal defect (ASD), especially sinus venosus defect (SVD). Although Waggstaffe described the pathology of SVDs in 1868, the exact anatomic features and the nature of SVD remains controversial. SVDs with no posterior atrial rim were observed in recent years. However, no studies suggested that absence of the residual posterior atrial septal tissue might be the key feature of SVD. The aims of this study were to investigate if absence of posterior rim of atrial septum played a crucial role in patients with SVD. Methods: From January 2011 to… More >

    A Rare Case of Infective Mediastinitis after Melody Valve Implantation

    Veronica Lorenz1, Karlien Carbonez2, Geoffroy de Beco1, Alain Poncelet1,*

    Congenital Heart Disease, Vol.17, No.2, pp. 187-192, 2022, DOI:10.32604/chd.2022.018350

    Abstract Pulmonary valve implant is frequently necessary in children and adults with congenital heart disease. Infective endocarditis represents a rare but life-threatening complication after transcatheter pulmonary valve implantation. There are various treatments for native or prosthetic valve endocarditis. Surgical intervention, combined with intravenous antibiotic treatment, is of paramount importance, in case of concomitant mediastinal infection, in order to ensure the radical debridement of all infected tissue, avoiding any recurrent endocarditis. In this report, we describe a rare case of mediastinitis, associated with an infected endocarditis, occurring 8 months after Melody (Medtronic®, Minneapolis, USA) valve implant, successfully treated with the implantation of… More >

    Transcatheter Device Closure of a Perimembranous Ventricular Septal Defect in Congenitally Corrected Transposition of the Great Arteries

    Catherine E. Tomasulo1,*, Lindsay S. Rogers1, Lauren Andrade1,2, Michael L. O’Byrne1,3,4

    Congenital Heart Disease, Vol.17, No.2, pp. 193-199, 2022, DOI:10.32604/chd.2022.017721

    Abstract The majority of patients with congenitally corrected transposition of the great arteries, also known as transposition of the great arteries {S,L,L} have ventricular septal defects (VSD), most commonly perimembranous VSD (pmVSD). Transcatheter device closure of pmVSD in these patients has not been widely described. We present a case of device closure of pmVSD in L-TGA with an Amplatzer Duct Occluder II (ADOII) device using a deployment starting in the subpulmonary left ventricle. The case demonstrates some of the technical advantages of the ADOII device for VSD closure, specifically its low profile, symmetric shape, and soft material. These characteristics are advantageous… More >

    Pregnancy in Patients with Shone Complex: A Single-Center Case Series

    Rachel Gardner1, Emily Durbak1, Rachael Baird2, Katherine Singh2, Jeff Chapa2, David Majdalany3,*

    Congenital Heart Disease, Vol.17, No.2, pp. 147-160, 2022, DOI:10.32604/chd.2022.017366

    Abstract Background: There is limited literature written on the course and outcomes for pregnant mothers with Shone complex. Methods: We describe a case series of five pregnancies in four women with Shone complex within a multidisciplinary cardio-obstetrics clinic from 2016–2018. Results: Maternal age ranged from 21–39 years. Three patients had preserved left ventricular function while one had moderately decreased function. Gestational age at presentation ranged from 6–15 weeks. There were three successful pregnancies (mean gestational age = 37 weeks, range 35–39 weeks) with one patient accounting for two unsuccessful pregnancies. All infants were delivered via Cesarean section. One infant required a… More >

    Medium-Term Results of Balloon Valvuloplasty of Native Pulmonary Valve Stenosis with and without Supravalvular Obstruction in Childhood

    Olivia Lenoir1,2, Daniel Quandt1,2, Oliver Kretschmar1,2, Walter Knirsch1,2,*

    Congenital Heart Disease, Vol.17, No.2, pp. 161-172, 2022, DOI:10.32604/chd.2022.016598

    Abstract Objectives: Factors influencing results of balloon valvuloplasty (BVP) of pulmonary valve stenosis (PS) in children are investigated. Background: BVP has become the standard of care for PS, medium-term results are not uniform and depend on various preconditions. Methods: We analysed the medium-term results of BVP of PS in children in an observational, single centre study. Need for additional procedure was defined as outcome after initial BVP. Results: We included 143 children (83 female) at a median (IQR) age of 2.6 (0.26–9.24) months and body weight of 5 (3.4–8) kg at BVP with a follow–up of 5.04 (1.6–10.2) years. We used… More >

    Facial Expression Recognition Based on the Fusion of Infrared and Visible Image

    Jiancheng Zou1, Jiaxin Li1,*, Juncun Wei1, Zhengzheng Li1, Xin Yang2

    Journal on Artificial Intelligence, Vol.3, No.3, pp. 123-134, 2021, DOI:10.32604/jai.2021.027069

    Abstract Facial expression recognition is a research hot spot in the fields of computer vision and pattern recognition. However, the existing facial expression recognition models are mainly concentrated in the visible light environment. They have insufficient generalization ability and low recognition accuracy, and are vulnerable to environmental changes such as illumination and distance. In order to solve these problems, we combine the advantages of the infrared and visible images captured simultaneously by array equipment our developed with two infrared and two visible lens, so that the fused image not only has the texture information of visible image, but also has the… More >

    Hao Chen*, Qian Tang, Yifei Wei, Mei Song

    Journal on Artificial Intelligence, Vol.3, No.3, pp. 115-121, 2021, DOI:10.32604/jai.2021.026851

    Abstract As the cost of accessing a telecom operator’s network continues to decrease, user churn after arrears occurred repeatedly, which has brought huge economic losses to operators and reminded them that it is significant to identify users who are likely to churn in advance. Machine learning can form a series of judgment rules by summarizing a large amount of data, and telecom user data naturally has the advantage of user scale, which can provide data support for learning algorithms. XGBoost is an improved gradient boosting algorithm, and in this paper, we explore how to use the algorithm to train an efficient… More >

    Saqlain Abbas1,2,*, Zulkarnain Abbas3, Xiaotong Tu4, Yanping Zhu1

    Journal on Artificial Intelligence, Vol.3, No.3, pp. 97-113, 2021, DOI:10.32604/jai.2021.023020

    Abstract The performance and reliability of structural components are greatly influenced by the presence of any abnormality in them. To this purpose, structural health monitoring (SHM) is recognized as a necessary tool to ensure the safety precautions and efficiency of both mechanical and civil infrastructures. Till now, most of the previous work has emphasized the functioning of several SHM techniques and systematic changes in SHM execution. However, there exist insufficient data in the literature regarding the patent-based technological developments in the SHM research domain which might be a useful source of detailed information for worldwide research institutes. To address this research… More >
