    Yazeed Alkhrijah1, Marwa Fahim2, Syed Muhammad Usman3, Qasim Mehmood3, Shehzad Khalid4,5,*, Mohamad A. Alawad1, Haya Aldossary6

    CMES-Computer Modeling in Engineering & Sciences, Vol.145, No.2, pp. 2339-2355, 2025, DOI:10.32604/cmes.2025.071512 - 26 November 2025

    Abstract Atrial Fibrillation (AF) is a cardiac disorder characterized by irregular heart rhythms, typically diagnosed using Electrocardiogram (ECG) signals. In remote regions with limited healthcare personnel, automated AF detection is extremely important. Although recent studies have explored various machine learning and deep learning approaches, challenges such as signal noise and subtle variations between AF and other cardiac rhythms continue to hinder accurate classification. In this study, we propose a novel framework that integrates robust preprocessing, comprehensive feature extraction, and an ensemble classification strategy. In the first step, ECG signals are divided into equal-sized segments using a… More >

    Case Report: A Rare Case of Left Atrial Aneurysm Following Isolated Staphylococcal Pericarditis in a Paediatric Patient Presenting as Constrictive Pericarditis

    Ji Lam Leong, Sivakumar Sivalingam*

    Congenital Heart Disease, Vol.20, No.3, pp. 341-346, 2025, DOI:10.32604/chd.2025.066461 - 11 July 2025

    Abstract Left atrial aneurysm is an exceptionally rare condition, particularly in the pediatric population, and even more so as a sequela of bacterial pericarditis. We present the case of a 16-month-old girl who developed a left atrial aneurysm following isolated Staphylococcus aureus pericarditis. She initially presented in decompensated shock and was later diagnosed with constrictive pericarditis. Despite undergoing pericardiectomy, she subsequently developed a left atrial aneurysm, necessitating surgical closure. This case highlights the aggressive nature of bacterial pericarditis and its potential to cause rare structural cardiac complications. More >

    Yaqi Tang1,#, Gang Luo1,#, Huashu Liu2, Hao Wan1, Silin Pan1,*

    Congenital Heart Disease, Vol.20, No.2, pp. 195-200, 2025, DOI:10.32604/chd.2025.063682 - 30 April 2025

    Abstract Congenital atrial septal defect (ASD) with severe scoliosis is a rare compound malformation in children. Severe scoliosis should be corrected as soon as possible. The growth rod is suitable for patients with early scoliosis and obvious scoliosis under 10 years old. However, the fluoroscopic radiopaque of titanium alloy plate will inevitably partly make the operative field of interventional occlusion blind. We present a 7-year-old Chinese girl with ASD and scoliosis who underwent spinal correction with a dual-growth rod. In this case, we performed transcatheter closure of ASD solely under the guidance of transthoracic echocardiography. Transthoracic More >

    Xu Liu, Yanjun Sun, Xiafeng Yu, Yiwei Liu, Hao Zhang*

    Congenital Heart Disease, Vol.20, No.1, pp. 103-113, 2025, DOI:10.32604/chd.2025.063108 - 18 March 2025

    Abstract Aorta–right atrial tunnel (ARAT) is an extremely rare congenital heart malformation with an average age of diagnosis of approximately 20 years. Its clinical symptoms are varied and often atypical. ARAT usually originates from the left or right sinus of Valsalva. In this case report, we aim to share a rare case of ARAT originating from the noncoronary sinus in an infant. The patient presented with a cardiac murmur, a dilated right heart, and a tortuous tunnel originating from the dilated noncoronary sinus and terminating at the right atrium in echocardiogram and computed tomography angiography.

    Congenital Heart Disease, Vol.19, No.5, pp. 457-472, 2024, DOI:10.32604/chd.2024.057151 - 31 December 2024

    Abstract Background: Post-operative atrial fibrillation (POAF) frequently occurs after cardiac surgery. Although adult congenital heart disease (ACHD) patients have higher rates of arrhythmia than the general population, there is scant literature on POAF in ACHD patients. Objectives: Identify key risk factors associated with post-operative atrial fibrillation and evaluate the short- and mid-term significance of developing POAF. Methods: A retrospective cohort study was conducted of ACHD patients from 2013–2021 at the University of Colorado Hospital and Children’s Hospital of Colorado. The institutional Society of Thoracic Surgeons (STS) surgical registry was used to identify patients ≥18-year-old with congenital heart… More >

    Right Axillary Thoracotomy Should Be the Standard of Care for Repair of Non-Complex Congenital Heart Defects in Infants and Children

    Sameh M. Said1,2,*, Yasin Essa1

    Congenital Heart Disease, Vol.19, No.4, pp. 407-417, 2024, DOI:10.32604/chd.2024.055636 - 31 October 2024

    Abstract Minimally invasive approaches for cardiac surgery in children have been lagging in comparison to the adult world. A wide range of the most common congenital heart defects in infants and children can be repaired successfully through a variety of non-sternotomy incisions. This has been shown to be associated with superior cosmetic results, shorter hospital stays, and rapid return to full activity compared to sternotomy. These approaches have been around for decades, but they have not been widely adopted for a variety of reasons. Right axillary thoracotomy is one of these approaches that we believe should More >

    Congenital Heart Disease, Vol.19, No.3, pp. 315-324, 2024, DOI:10.32604/chd.2024.051587 - 26 July 2024

    Abstract Background and Objective: The most feared complication of uncorrected secundum Atrial Septal Defect (ASD) is pulmonary arterial hypertension (PAH). Pulmonary vascular resistance (PVR) is crucial in detecting precapillary pulmonary hypertension (PH) to guide the need for PAH-specific therapy. There is a change in the cut-off value of PVR according to the recently updated PH guideline. How echocardiographic PVR (PVR) correlates to PVR by right heart catheterization (RHC) (PVR) according to the new guidelines has not been known. The aim of this study is to determine the reliability of PVR in detecting PAH in Uncorrected Ostium… More > Graphic Abstract
