    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… More > Graphic Abstract

    A Novel Deep Learning Framework for Pulmonary Embolism Detection for Covid-19 Management

    S. Jeevitha1,*, K. Valarmathi2

    Intelligent Automation & Soft Computing, Vol.34, No.2, pp. 1123-1139, 2022, DOI:10.32604/iasc.2022.024746 - 03 May 2022

    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… 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 - 22 September 2021

    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… More >

    Congenital Heart Disease, Vol.16, No.2, pp. 107-121, 2021, DOI:10.32604/CHD.2021.014164 - 26 January 2021

    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… More >

    Molecular & Cellular Biomechanics, Vol.17, No.2, pp. 63-74, 2020, DOI:10.32604/mcb.2020.08750

    Abstract Computational fluid dynamics (CFD) has been widely used for studying intracranial aneurysm hemodynamics, while its use for guiding clinical strategy is still in development. In this study, CFD simulations helped inform treatment decision for a middle cerebral artery (MCA) aneurysm case was investigated. A patient with a 10.4 × 9.8 mm aneurysm attached with a small aneurysm at the edge of the trifurcation in the left MCA was included in this study. For removing the MCA aneurysm, two scenarios were considered: Plan-A involved clipping the small aneurysm and Plan-B involved clipping the whole aneurysm. A… More >

    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… More >

    Sok‐Leng Kang1, Aimee Armstrong2, Gregor Krings3, Lee Benson1

    Congenital Heart Disease, Vol.14, No.6, pp. 1046-1057, 2019, DOI:10.1111/chd.12838

    Abstract Three‐dimensional rotational angiography (3D‐RA) enables volumetric imaging through rotation of the C‐arm of an angiographic system and real‐time 3D recon‐ struction during cardiac catheterization procedures. In the field of congenital heart disease (CHD), 3D‐RA has gained considerable traction, owing to its capability for en‐ hanced visualization of spatial relationships in complex cardiac morphologies and real time image guidance in an intricate interventional environment. This review provides an overview of the current applications, strengths, and limitations of 3D‐RA acquisi‐ tion in the management of CHD and potential future directions. In addition, issues of dosimetry, radiation exposure, More >
