    Abstract Background: Anomalous aortic origin of a coronary artery (AAOCA) is a congenital heart disease with a 0.3%−0.5% prevalence. Diagnosis is challenging due to nonspecific clinical presentation. Risk stratification and treatment are currently based on expert consensus and single-center case series. Methods: Demographical and clinical data of AAOCA patients from 17 tertiary-care centers were analyzed. Diagnostic imaging studies (Bidimensional echocardiography, coronary computed tomography angiography [CCTA] were collected. Clinical correlations with anomalous coronary course and origin were evaluated. Results: Data from 239 patients (42% males, mean age 15 y) affected by AAOCA were collected; 154 had AAOCA involving the right coronary artery… More > Graphic Abstract

    S. Jeevitha1,*, K. Valarmathi2

    Intelligent Automation & Soft Computing, Vol.34, No.2, pp. 1123-1139, 2022, DOI:10.32604/iasc.2022.024746

    Abstract Pulmonary Embolism is a blood clot in the lung which restricts the blood flow and reduces blood oxygen level resulting in mortality if it is untreated. Further, pulmonary embolism is evidenced prominently in the segmental and sub-segmental regions of the computed tomography angiography images in COVID-19 patients. Pulmonary embolism detection from these images is a significant research problem in the challenging COVID-19 pandemic in the venture of early disease detection, treatment, and prognosis. Inspired by several investigations based on deep learning in this context, a two-stage framework has been proposed for pulmonary embolism detection which is realized as a segmentation… More >

    Maryam Altalhi1, Sami Ur Rehman2, Fakhre Alam2, Ala Abdulsalam Alarood3, Amin ur Rehman2, M. Irfan Uddin4,*

    Intelligent Automation & Soft Computing, Vol.31, No.2, pp. 961-969, 2022, DOI:10.32604/iasc.2022.020607

    Abstract The proper computation of geometric parameters of the aorta and coronary arteries are very important for surgery planning, disease diagnoses, and age-related changes observation in the vessels. The accurate knowledge about the geometry of aorta and coronary arteries is required for the proper investigation of heart related diseases. The geometry of aorta and coronary arteries includes the diameter of the ascending and descending aorta and coronary arteries, length of the coronary arteries, branching angles of the coronary arteries and branching points. These geometric parameters from arteries can be computed from the 3D image data. In this paper, we propose an… More >

    3.0T MR Coronary Angiography after Arterial Switch Operation for Transposition of The Great Arteries—Gd-FLASH Versus Non-Enhanced SSFP. A Feasibility Study

    Kathrine Rydén Suther1,*, Charlotte de Lange1,2, Henrik Brun3, Rolf Svendsmark1, Bac Nguyen1, Stig Larsen4, Bjarne Smevik1, Arnt Eltvedt Fiane5,6, Harald Lauritz Lindberg6, Einar Hopp1

    Congenital Heart Disease, Vol.16, No.2, pp. 107-121, 2021, DOI:10.32604/CHD.2021.014164

    Abstract Background: Patency of the coronary arteries is an issue after reports of sudden cardiac death in patients with transposition of the great arteries (TGA) operated with arterial switch (ASO). Recent studies give rise to concern regarding the use of ionising radiation in congenital heart disease, and assessment of the coronary arteries with coronary MR angiography (CMRA) might be an attractive non-invasive, non-ionising imaging alternative in these patients. Theoretically, the use of 3.0T CMRA should improve the visualisation of the coronary arteries. The objective of this study was to assess feasibility of 3.0T CMRA at the coronary artery origins by comparing… More >

    Interobserver variability in the classification of congenital coronary abnormalities: A substudy of the anomalous connections of the coronary arteries registry

    Athanasios Koutsoukis1, Xavier Halna du Fretay2, Patrick Dupouy3, Phalla Ou4, Jean-Pierre Laissy4, Jean-Michel Juliard5, Fabien Hyafil6, Pierre Aubry5

    Congenital Heart Disease, Vol.12, No.6, pp. 726-732, 2017, DOI:10.1111/chd.12504

    Abstract Objective: The diagnosis of anomalous connections of the coronary arteries (ANOCOR) requires an appropriate identification for the management of the patients involved. We studied the observer variability in the description and classification of ANOCOR between a nonexpert group of physicians and a group of expert physicians, using the ANOCOR cohort.
    Patients and design: Consecutive patients identified by 71 referring cardiologists were included in the ANOCOR cohort. Anomalous connection was diagnosed by invasive and/or computed tomography coronary angiography. Angiographic images were reviewed by an angiographic committee with experience in this field. Both investigators and angiographic committee filled out a questionnaire to… More >

    Impact of contrast exposure from computed tomography angiography on acute kidney injury after neonatal cardiopulmonary bypass surgery

    Waldemar F. Carlo1, Steven T. Clark2, Santiago Borasino3, Jeffrey A. Alten3

    Congenital Heart Disease, Vol.12, No.4, pp. 540-545, 2017, DOI:10.1111/chd.12482

    Abstract Objective: Acute kidney injury (AKI) is a frequent complication after cardiopulmonary bypass (CBP) for cardiac surgery in neonates. It is unclear if exposure to computed tomography angiography (CTA) in the preoperative period increases the risk of AKI. We hypothesized a short interval between CTA and CPB surgery would be associated with higher rates of AKI in infants.
    Design: In this single center retrospective review of patients between 2012 and 2015, neonates less than one month old were analyzed if they had CTA prior to cardiac surgery with CPB. Baseline, demographic, fluid balance, and laboratory data was analyzed. AKI was staged… More >

    Reducing radiation exposure by lowering frame rate in children undergoing cardiac catheterization: A quality improvement study

    Shahnawaz M. Amdani, Robert D. Ross, Paul A. Webster, Daniel R. Turner, Thomas J. Forbes, Daisuke Kobayashi

    Congenital Heart Disease, Vol.13, No.6, pp. 1028-1037, 2018, DOI:10.1111/chd.12677

    Abstract Introduction: Reduction of radiation dosage in the pediatric cardiac catheterization laboratory (PCL) is important to reduce the risk of its stochastic effect in children with congenital heart disease. Lowering the frame rate would reduce radiation dos‐ age possibly at the expense of image quality, potentially resulting in higher fluoro‐ scopic time and procedural complication rate.
    Methods: The data were retrospectively analyzed in three eras: era 1 (n = 234), cine‐ angiography 30 frames/sec (f/s) and fluoroscopy 15 pulse/sec (p/s); era 2 (n = 381), cineangiography 30 f/s and fluoroscopy 6 p/s; and era 3 (n = 328), cineangiography 15 f/s… More >

    Congenital Heart Disease, Vol.14, No.6, pp. 1087-1093, 2019, DOI:10.1111/chd.12853

    Abstract Objective: This study aims to investigate the changes in renal function and levels of urinary biomarkers before and after cardiac angiography in children with congenital heart disease (CHD).
    Setting: Children with CHD are at a risk for kidney injury during contrast exposure in cardiac angiography.
    Outcome Measures: We measured urinary protein, albumin, N‐acetyl‐β‐D‐glucosaminidase (NAG), β2‐microglobulin (BMG), and liver‐type fatty acid‐binding protein (L‐FABP) levels, as well as serum creatinine and cystatin C levels, before and after cardiac angiography in 33 children with CHD.
    Results: No significant decrease was noted in either the creatinine‐based or cystatin C‐based estimated glomerular filtration rate at… More >

    Coronary artery disease screening in adults with congenital heart disease prior to cardiac surgery

    Bradley Johnson1,2, Matthew Buelow1,2, Michael Earing1,2, Scott Cohen1,2, Peter Bartz1,2, Salil Ginde1,2

    Congenital Heart Disease, Vol.14, No.6, pp. 895-900, 2019, DOI:10.1111/chd.12839

    Abstract Objective: As adults with congenital heart disease (CHD) grow older, preoperative screening for coronary artery disease (CAD) may be indicated prior to CHD surgery. Data regarding the indications for preoperative CAD screening in this population are limited. Current practice is to follow guidelines for patients with valvular heart dis‐ ease; however, the risk for CAD in certain congenital heart diagnoses may be higher than the general population. This study aimed to assess the results of preoperative CAD screening in patients prior to CHD surgery.
    Design: Retrospective study.
    Setting: Single tertiary center.
    Patients: Patients ≥35 years that had CHD surgery from… More >
