    Pier Paolo Bassareo1,2,3,*, Aurelio Secinaro4, Paolo Ciliberti5, Massimo Chessa6,7, Marco Alfonso Perrone5,8, Kevin Patrick Walsh1,2,3, Colin Joseph Mcmahon2,3

    Congenital Heart Disease, Vol.18, No.6, pp. 595-610, 2023, DOI:10.32604/chd.2023.046229

    Abstract Background: Congenital absence of pericardium (CAP), also known as pericardial agenesis, represents an uncommon cardiac abnormality and mostly incidental finding. It can be subdivided into complete and partial (left or right-sided) forms. Because of its infrequency, just case reports and a few case series have been released so far. This paper represents the largest systematic review in the field. Nine features (age at diagnosis, type, gender, clinical presentation, electrocardiography, imaging (ultrasounds, CT/MRI), concomitant cardiac defects, and outcome) were analysed. Methods: The electronic database PubMed was investigated from its establishment up to July 15th, 2023. Just case… More >

    Abstract Background: The assessment of Fontan circuit’s flow is traditionally evaluated by multiple through-plane phase-contrast MRI acquisitions (2D flow), while recently, a single volumetric 4D-flow MRI acquisition is emerging as a comprehensive tool for the hemodynamic evaluation in congenital heart diseases. Purpose: To compare 2D and 4D-flow MRI measurements in patients after Fontan palliation and to evaluate parameters affecting potential disagreement. Methods: 39 patients after Fontan palliation (23 males, age 22 ± 11 years) who underwent cardiac MRI with 2D and 4D-flow MRI acquisition were included in the study. In all patients, blood flow quantification in the… More > Graphic Abstract

    The Effect of Atrial Septal Defect Closure on Cardiac Volumetric Changes in Adults, Transcatheter Versus Surgical Closure, a Pilot Cardiac Magnetic Resonance Study

    Amr Mansour1, Noha M. Gamal2,*, Alaa M. Nady3, Amr Ibraheem3, Dalia M. Salah4, Khaled M. El-Maghraby2

    Congenital Heart Disease, Vol.18, No.6, pp. 679-691, 2023, DOI:10.32604/chd.2023.020028

    Abstract Background: Closure of an atrial septal defect (ASD) reduces right-side heart volumes by abolishing shunting with simultaneous improvement of the left ventricle (LV) filling and functions due to ventricular interdependence, thereby improving symptoms. Furthermore, studies conducted on atrial volume changes after ASD closure are limited. Cardiac magnetic resonance (CMR) is considered as the gold standard method for measuring cardiac volume and mass. Objective: We aimed to study the effect of transcatheter and surgical closure of secundum ASD on cardiac volumes and systolic functions as well as the fate of tricuspid regurgitation (TR), using CMR analysis.

    A Multi-Task Network for Cardiac Magnetic Resonance Image Segmentation and Classification

    Jing Peng1,2,4, Chaoyang Xia2, Yuanwei Xu3, Xiaojie Li2, Xi Wu2, Xiao Han1,4, Xinlai Chen5, Yucheng Chen3, Zhe Cui1,4,*

    Intelligent Automation & Soft Computing, Vol.30, No.1, pp. 259-272, 2021, DOI:10.32604/iasc.2021.016749

    Abstract Cardiomyopathy is a group of diseases that affect the heart and can cause serious health problems. Segmentation and classification are important for automating the clinical diagnosis and treatment planning for cardiomyopathy. However, this automation is difficult because of the poor quality of cardiac magnetic resonance (CMR) imaging data and varying dimensions caused by movement of the ventricle. To address these problems, a deep multi-task framework based on a convolutional neural network (CNN) is proposed to segment the left ventricle (LV) myocardium and classify cardiopathy simultaneously. The proposed model consists of a longitudinal encoder–decoder structure that… More >

    Evolutionary GAN–Based Data Augmentation for Cardiac Magnetic Resonance Image

    Ying Fu1,2,*, Minxue Gong1, Guang Yang1, Hong Wei3, Jiliu Zhou1,2

    CMC-Computers, Materials & Continua, Vol.68, No.1, pp. 1359-1374, 2021, DOI:10.32604/cmc.2021.016536

    Abstract Generative adversarial networks (GANs) have considerable potential to alleviate challenges linked to data scarcity. Recent research has demonstrated the good performance of this method for data augmentation because GANs synthesize semantically meaningful data from standard signal distribution. The goal of this study was to solve the overfitting problem that is caused by the training process of convolution networks with a small dataset. In this context, we propose a data augmentation method based on an evolutionary generative adversarial network for cardiac magnetic resonance images to extend the training data. In our structure of the evolutionary GAN,… More >

    Congenital Heart Disease, Vol.12, No.4, pp. 458-466, 2017, DOI:10.1111/chd.12472

    Abstract Objectives: We aimed (1) determine if systemic right ventricle filling parameters influence systemic right ventricle stroke volume in adult patients with D-transposition of the great arteries (D-TGA) palliated by atrial switch, using cardiac magnetic resonance imaging and echocardiography, and (2) to study relationship of these diastolic parameters with exercise performance and BNP, in patients with preserved systolic systemic right ventricle function.
    Design: Single-center, cross-sectional, prospective study.
    Setting: In patients with D-TGA palliated by atrial switch, diastolic dysfunction of the systemic right ventricle may precede systolic dysfunction.
    Methods: Forty-five patients with D-TGA and atrial switch and 45 age and sex-matched… More >

    Mary K. Olive1, Charles D. Fraser2, Shelby Kutty3, Emmett D. McKenzie4, James M. Hammel5, Rajesh Krishnamurthy6, Nicolas A. Dodd7, Shiraz A. Maskatia8

    Congenital Heart Disease, Vol.14, No.6, pp. 1149-1156, 2019, DOI:10.1111/chd.12863

    Abstract Introduction: The right ventricular infundibular sparing approach (RVIS) to the repair of tetralogy of Fallot (TOF) avoids a full-thickness ventricular incision, typically utilized in the transinfundibular (TI) method.
    Methods: We performed a retrospective, age-matched cohort study of patients who underwent RVIS at Texas Children’s Hospital or TI at Children’s Hospital Medical Center in Nebraska and subsequently underwent cardiac magnetic resonance imaging (CMR). We compared right ventricular end-diastolic and systolic volumes indexed to body surface area (RVEDVi and RVESVi) and right ventricular ejection fraction (RVEF) as primary endpoints. Secondary endpoints were indexed left ventricular diastolic and systolic volume… More >

    Echocardiography vs cardiac magnetic resonance imaging assessment of the systemic right ventricle for patients with d-transposition of the great arteries status post atrial switch

    Margaret M. Samyn1,2, Ke Yan1, Conor Masterson3, Benjamin H. Goot1,2, David Saudek1,2, Julie Lavoie2, Aaron Kinney2, Mary Krolikowski1, Kan Hor4,5, Scott Cohen1,2

    Congenital Heart Disease, Vol.14, No.6, pp. 1138-1148, 2019, DOI:10.1111/chd.12861

    Abstract Objective: Patients with Dextro-transposition of the great arteries status post atrial switch (dTGA s/p atrial switch) are “at-risk” for systemic right ventricular (RV) dysfunction. Due to complex RV geometry, echocardiography (Echo) does not allow accurate determination of ejection fraction (EF), but cardiac magnetic resonance imaging (CMR) allows quantitative right ventricular assessment. Measures of ventricular deformation may be precursors to global ventricular dysfunction. The primary aim of this study was to characterize imaging and clinical findings for adult patients with dTGA s/p atrial switch.
    Design: This was a retrospective cohort study of patients with dTGA s/p atrial switch… More >

    Neil C. Zaki1,2, Michael S. Kelleman1, W. James Parks1,3, Timothy C. Slesnick1,3, Michael E. McConnell1,3, Matthew E. Oster1,3

    Congenital Heart Disease, Vol.14, No.2, pp. 140-146, 2019, DOI:10.1111/chd.12692

    Abstract Objective: Gated cardiac MRI offers the most detailed and accurate noninvasive method of assessing cardiac anatomy, particularly in patients with complex congenital heart disease. The proposed benefits of using cMRI as a routine screening tool in the Fontan population include early recognition of asymptomatic, postoperative anatomic and physiologic changes. In 2011, we therefore instituted at our center a recommended practice of cMRI screening in patients with Fontan physiology at 3 and 8 years postFontan operation. The purpose of this study was to determine the impact of this standardized practice of cMRI screening on the clinical management… More >

    A Multi-Scale Network with the Encoder-Decoder Structure for CMR Segmentation

    Chaoyang Xia1, Jing Peng1, Zongqing Ma2, Xiaojie Li1,*

    Journal of Information Hiding and Privacy Protection, Vol.1, No.3, pp. 109-117, 2019, DOI:10.32604/jihpp.2019.07198

    Abstract Cardiomyopathy is one of the most serious public health threats. The precise structural and functional cardiac measurement is an essential step for clinical diagnosis and follow-up treatment planning. Cardiologists are often required to draw endocardial and epicardial contours of the left ventricle (LV) manually in routine clinical diagnosis or treatment planning period. This task is time-consuming and error-prone. Therefore, it is necessary to develop a fully automated end-to-end semantic segmentation method on cardiac magnetic resonance (CMR) imaging datasets. However, due to the low image quality and the deformation caused by heartbeat, there is no effective… More >
