    Cheryl Dickson1,2,4, Danielle Osborn1, David Baker1,4, Judith Fethney3, David S. Celermajer1,4, Rachael Cordina1,4,*

    Congenital Heart Disease, Vol.19, No.1, pp. 49-63, 2024, DOI:10.32604/chd.2023.044874

    Abstract Background: Much has been written about the loss to follow-up in the transition between pediatric and adult Congenital Heart Disease (CHD) care centers. Much less is understood about the loss to follow-up (LTF) after a successful transition. This is critical too, as patients lost to specialised care are more likely to experience morbidity and premature mortality. Aims: To understand the prevalence and reasons for loss to follow-up (LTF) at a large Australian Adult Congenital Heart Disease (ACHD) centre. Methods: Patients with moderate or highly complex CHD and gaps in care of >3 years (defined as LTF)… More >

    Research on the Follow-Up Control Strategy of Biaxial Fatigue Test of Wind Turbine Blade Based on Electromagnetic Excitation

    Wenzhe Guo1, Leian Zhang1,*, Chao Lv2, Weisheng Liu3, Jiabin Tian2

    Energy Engineering, Vol.120, No.10, pp. 2307-2323, 2023, DOI:10.32604/ee.2023.030029

    Abstract Aiming at the drift problem that the tracking control of the actual load relative to the target load during the electromagnetic excitation biaxial fatigue test of wind turbine blades is easy to drift, a biaxial fatigue testing machine for electromagnetic excitation is designed, and the following strategy of the actual load and the target load is studied. A Fast Transversal Recursive Least Squares algorithm based on fuzzy logic (Fuzzy FTRLS) is proposed to develop a fatigue loading following dynamic strategy, which adjusts the forgetting factor in the algorithm through fuzzy logic to overcome the contradiction More >

    Congenital Heart Disease, Vol.18, No.2, pp. 219-234, 2023, DOI:10.32604/chd.2023.027562

    Abstract Background: The Venus-P valve was the first self-expanding valve used world-wide for transcatheter pulmonary valve replacement (TPVR) in patients with severe pulmonary regurgitation (PR). We intended to report the extended follow-up results from the prospective trial (No. NCT02590679). Methods: A total of 38 patients with severe PR (mean age 24.2 ± 13.2) were included. Follow-up data were obtained after implanted at 1, 6, and 12 months and yearly after. The frame geometry was assessed on post-implant computer tomography (CT) scanning by calculating the non-circularity [circularity ratio (minimum diameter/maximum diameter) < 0.9] and under-expansion [expansion ratio (derived external valve… More > Graphic Abstract

    A 20-Year Follow-up after the Fontan Operation in a Population with Hypoplastic Left Heart Syndrome

    Eleni P. Asimacopoulos*, Steven J. Staffa, Peter C. Laussen, Kirsten C. Odegard

    Congenital Heart Disease, Vol.17, No.5, pp. 579-590, 2022, DOI:10.32604/chd.2022.020334

    Abstract Background: Thromboembolic events are a cause of significant morbidity and mortality in the Fontan population. We previously reported on coagulation profile changes in a cohort of patients with hypoplastic left heart syndrome (HLHS) from Stage I through Fontan completion. In this report, we examine their clinical status, anticoagulation and incidence of thromboembolic events up to 20 years post Fontan. Methods: A retrospective chart review was conducted for twenty (20) surviving patients, from 1998 through December 2020. Patients who underwent orthotopic heart transplantation (OTx) were followed until their transplant. Patients who were found in the original study… More >

    Surgical Versus Percutaneous Stenting Treatment of Isolated Aortic Coarctation: Long-Term Follow-Up

    Marie Laure Yammine#,*, Camilla Calvieri#, Marcello Chinali, Salvatore Giannico, Giulia Cafiero, Ugo Giordano

    Congenital Heart Disease, Vol.16, No.5, pp. 457-467, 2021, DOI:10.32604/CHD.2021.015896

    Abstract Background: In recent decades, aortic stenting has become a promising alternative to surgery for both native aortic coarctation and re-stenosis in children and adults. However, comparative long-term outcomes have poorly been investigated. Methods: We included 212 patients with previous aortic repair (19 ± 8.7 years) divided into 3 groups: 139 with single-time surgical repair (CoA-S group); 18 with single-time percutaneous stenting (CoA-PS group); and 55 hybrid patients with multiple aortic procedures because of re-coarctation occurrence (CoA-H group). All patients underwent 24-hour ambulatory blood pressure monitoring and trans-thoracic echocardiography. Results: After a median follow-up of 17 years after… More >

    Tânia Branco Mano1,*, João Ferreira Reis1, Ana Figueiredo Agapito1, André Monteiro1, Mário Oliveira1, Luísa Moura Branco1, José Fragata2, Fátima Pinto3, Rui Cruz Ferreira1, Lídia de Sousa1

    Congenital Heart Disease, Vol.15, No.3, pp. 153-162, 2020, DOI:10.32604/CHD.2020.011500

    Abstract Introduction: Due to the low prevalence and wide variation of severity of Ebstein’s Anomaly (EA), long-term follow-up data are scarce. The aim was to evaluate the long-term outcome of an adult population with EA. Methods: Retrospective analysis of EA adults followed in the past 42 years in a tertiary congenital heart disease outpatient clinic. Predictors of complications and mortality were assessed. Results: We studied 53 patients: 53% females, mean age 46 ± 19 years, 36% cyanotic, 55% diagnosed at adult age. Tricuspid regurgitation was moderate or severe in 33% and 46%, respectively, and during follow-up (mean… More >

    Improving the quality of transition and transfer of care in young adults with congenital heart disease

    Ian K. Everitt1, Jennifer F. Gerardin2, Fred H. Rodriguez2,3, Wendy M. Book2

    Congenital Heart Disease, Vol.12, No.3, pp. 242-25, 2017, DOI:10.1111/chd.12463

    Abstract The transition and transfer from pediatric to adult care is becoming increasingly important as improvements in the diagnosis and management of congenital heart disease allow patients to live longer. Transition is a complex and continuous process that requires careful planning. Inadequate transition has adverse effects on patients, their families and healthcare delivery systems. Currently, significant gaps exist in patient care as adolescents transfer to adult care and there are little data to drive the informed management of transition and transfer of care in adolescent congenital heart disease patients. Appropriate congenital heart disease care has been… More >

    Maryanne Caruana1, Victor Grech2

    Congenital Heart Disease, Vol.12, No.3, pp. 301-308, 2017, DOI:10.1111/chd.12439

    Abstract Objectives: To determine overall and reintervention-free survival for repaired Maltese tetralogy of Fallot patients and to investigate the potential impact of gender, age at repair, genetic syndromes, previous palliation, and type of repair on these outcomes.
    Design: All 130 tetralogy of Fallot patients born before the end of 1997 included in the local database were extracted. Surgical repair type, age at repair and operative survival were analyzed among the 103/130 repaired patients. Kaplan–Meier survival analyses were performed on the 75 repair survivors with complete follow-up data (mean follow-up 26.37 ± 9.27 (range 9.95–51.21) years).
    Results: Patients born after… More >
