    Optimized Three-Dimensional Cardiovascular Magnetic Resonance Whole Heart Imaging Utilizing Non-Selective Excitation and Compressed Sensing in Children and Adults with Congenital Heart Disease

    Ingo Paetsch1,*, Roman Gebauer2, Christian Paech2, Frank-Thomas Riede2, Sabrina Oebel1, Andreas Bollmann1, Christian Stehning3, Jouke Smink4, Ingo Daehnert2, Cosima Jahnke1

    Congenital Heart Disease, Vol.18, No.3, pp. 279-294, 2023, DOI:10.32604/chd.2023.029634

    Abstract Background: In congenital heart disease (CHD) patients, detailed three-dimensional anatomy depiction plays a pivotal role for diagnosis and therapeutical decision making. Hence, the present study investigated the applicability of an advanced cardiovascular magnetic resonance (CMR) whole heart imaging approach utilizing nonselective excitation and compressed sensing for anatomical assessment and interventional guidance of CHD patients in comparison to conventional dynamic CMR angiography. Methods: 86 consecutive pediatric patients and adults with congenital heart disease (age, 1 to 74 years; mean, 35 years) underwent CMR imaging including a free-breathing, ECG-triggered 3D nonselective SSFP whole heart acquisition using compressed SENSE (nsWHcs). Anatomical assessability and… More >

    A Ring-Reinforced Right Ventricle to Pulmonary Artery Conduit is Associated with Better Regional Mechanics after Stage I Norwood Operation

    Benjamin Zielonka1,2,*, David M. Harrild1,2, Sunil J. Ghelani1,2, Eleni G. Elia1,2, Christopher W. Baird3,4, Andrew J. Powell1,2, Rahul H. Rathod1,2

    Congenital Heart Disease, Vol.17, No.5, pp. 591-603, 2022, DOI:10.32604/chd.2022.021509

    Abstract Background: The right ventricle to pulmonary artery conduit (RVPAC) may impair right ventricular (RV) function in patients with functional single right ventricles. Modification of the RVPAC using a ring-reinforced end with dunked insertion into the RV through a limited ventriculotomy may reduce the impact on RV function. We compared RV segmental strain between patients with a traditional RVPAC and ring-reinforced RVPAC using feature tracking cardiovascular magnetic resonance (CMR) imaging. Methods: Patients with CMR examinations after Stage I operation with RVPAC between 2000 and 2018 were reviewed. Ventricular mass, volumes, late gadolinium enhancement (LGE), and peak radial and circumferential strain of… More >

    The Impact of a Bicuspid Aortic Valve on Aortic Geometry and Function in Patients with Aortic Coarctation: A Comprehensive CMR Study

    Laura Schweikert1, Dominik Gabbert1, Sylvia Krupickova2, Inga Voges1,*

    Congenital Heart Disease, Vol.16, No.6, pp. 551-560, 2021, DOI:10.32604/CHD.2021.016635

    Abstract Background: An isolated bicuspid aortic valve (BAV) is associated with structural and functional abnormalities of the aorta and the left ventricle (LV). Although ~50% of patients with aortic coarctation (CoA) have a BAV, less is known about its impact on LV function and aortic geometry and function in CoA patients. In this cardiovascular magnetic resonance imaging (CMR) study, we analysed markers of LV and aortic function as well as aortic geometry in a large cohort of CoA patients with a BAV and compared them with CoA patients with a tricuspid aortic valve (TAV). Methods: We included 48 patients with a… More >

    Assessing Univentricular Function in Adult Fontan Using 3D Echocardiography

    Karina V. Bunting1,2,*, Francesco Formisano3, Jennifer Green1, Richard P. Steeds1,2, Lucy Hudsmith1, Paul Clift1,2

    Congenital Heart Disease, Vol.15, No.2, pp. 89-100, 2020, DOI:10.32604/CHD.2020.011376

    Abstract Objective: To determine the accuracy of assessing univentricular function in adult Fontan patients using three-dimensional (3D) volumetric echocardiography. Design: A prospective observational study in an adult Fontan patient cohort. Setting: University Hospitals Birmingham, NHS Foundation Trust. Patients: 26 patients were enrolled in the study all aged over 18 years, possessing the Fontan anatomy, with no contraindications to Cardiac Magnetic Resonance (CMR) imaging and in sinus rhythm. Intervention: All patients underwent transthoracic echocardiography using a Philips EPIQ 7 and X5-1 transducer. End diastolic volume (EDV), end systolic volume (ESV), stroke volume (SV) and ejection fraction (EF) were obtained using two dimensional… More >

    Knowledge-based reconstruction for measurement of right ventricular volumes on cardiovascular magnetic resonance images in a mixed population

    Elise D. Pieterman1,2, Ricardo P. J. Budde2, Danielle Robbers-Visser1,2, Ron T. van Domburg3, Willem A. Helbing1,2

    Congenital Heart Disease, Vol.12, No.5, pp. 561-569, 2017, DOI:10.1111/chd.12484

    Abstract Objective: Follow-up of right ventricular performance is important for patients with congenital heart disease. Cardiac magnetic resonance imaging is optimal for this purpose. However, observerdependency of manual analysis of right ventricular volumes limit its use. Knowledge-based reconstruction is a new semiautomatic analysis tool that uses a database including knowledge of right ventricular shape in various congenital heart diseases. We evaluated whether knowledge-based reconstruction is a good alternative for conventional analysis.
    Design: To assess the inter- and intra-observer variability and agreement of knowledge-based versus conventional analysis of magnetic resonance right ventricular volumes, analysis was done by two observers in a mixed… More >

    Pharmacologic stress cardiovascular magnetic resonance in the pediatric population: A review of the literature, proposed protocol, and two examples in patients with Kawasaki disease

    Munes Fares1, Paul J. Critser2, Maria J. Arruda1, Carolyn M. Wilhelm1, Mantosh S. Rattan3, Sean M. Lang2,4, Tarek Alsaied2,4

    Congenital Heart Disease, Vol.14, No.6, pp. 1166-1175, 2019, DOI:10.1111/chd.12840

    Abstract Pharmacologic stress cardiovascular magnetic resonance (PSCMR) is a wellestablished and reliable diagnostic tool for evaluation of coronary artery disease in the adult population. Stress imaging overall and PSCMR in particular is less utilized in the pediatric population with limited reported data. In this review, we highlight the potential use of PSCMR in specific pediatric cohorts with congenital and acquired heart disease, and we review the reported experience. A suggested protocol is presented in addition to two case examples of patients with Kawasaki disease where PSCMR aided decision making. More >
