Background: Cardiac Computed Tomography (CCT) is increasingly used to provide 2D, 3D and 4D information in patients with congenital heart disease of all ages. Historically, negotiated rates for professional and technical fees associated with cardiac imaging were confidential, with variability in professional, technical and global charges, reimbursement and cost to patients for the same current procedural terminology (CPT) code at different institutions. Billing transparency is a key component of both the CARE act passed in 2020 and the Health Care PRICE Transparency Act 2.

Background: Cardiac Computed Tomography (CCT) is increasingly used for evaluation of congenital heart disease (CHD) in patients of all ages. Pediatric and adult congenital heart disease (ACHD) surgical programs require high quality CCT imaging as part of the multimodality imaging support expected of comprehensive care centers. Despite these expectations, there are no benchmarks or defined programmatic elements specific to the performance of CCT in patients with CHD.

Anomalous coronary arteries are associated with sudden cardiac death, although only in a relatively small percentage. Although this has been a field of study for years and there are many ongoing studies of larger patient cohorts and longer term follow-up, important questions remain at present in clinical decision-making, particularly whether or not to have surgery. Advanced imaging techniques including coronary computed tomography (CT) and cardiac magnetic resonance (MR) play an important role in the workup of patients with known or suspected anomalies including delineating origin and course as well as defining presence of high-risk imaging features.

This consensus document for the performance of cardiovascular computed tomography (CCT) to guide intervention in the right ventricular outflow tract (RVOT) in patients with congenital disease (CHD) was developed collaboratively by pediatric and adult interventionalists, surgeons and cardiac imagers with expertise specific to this patient subset. The document summarizes definitions of RVOT dysfunction as assessed by multi-modality imaging techniques and reviews existing consensus statements and guideline documents pertaining to indications for intervention. In the context of this background information, recommendations for CCT scan acquisition and a standardized approach for reporting prior to surgical or transcatheter pulmonary valve replacement are proposed and presented.

Patients with many forms of congenital heart disease (CHD) and hypertrophic cardiomyopathy undergo surgical intervention to relieve left ventricular outflow tract obstruction (LVOTO). Cardiovascular Computed Tomography (CCT) defines the complex pathway from the ventricle to the outflow tract and can be visualized in 2D, 3D, and 4D (3D in motion) to help define the mechanism and physiologic significance of obstruction. Advanced cardiac visualization may aid in surgical planning to relieve obstruction in the left ventricular outflow tract, aortic or neo-aortic valve and the supravalvular space.

Article Synopsis
  • * The review covers various imaging methods like echocardiography, MRI, and 3D modeling, and emphasizes the role of artificial intelligence in enhancing these technologies.
  • * There is a need for further studies to assess the clinical effectiveness and cost-benefit of these imaging techniques, along with a focus on education and training for better implementation in clinical settings.

Congenital heart disease patients with pulmonary valve replacement or right ventricle-pulmonary artery conduit have increased risk of pulmonary valve endocarditis. We present a 6-patient case series illustrating the diagnostic utility of computed tomography angiography to provide definitive visualization of pulmonary valve vegetation to aid in the diagnosis of endocarditis.

Cardiovascular computed tomography (CCT) is rated appropriate by published guidelines for the initial evaluation and follow up of congenital heart disease (CHD) and is an essential modality in cardiac imaging programs for patients of all ages. However, no recommended core competencies exist to guide CCT in CHD imaging training pathways, curricula development, or establishment of a more formal educational platform. To fill this gap, a group of experienced congenital cardiac imagers, intentionally inclusive of adult and pediatric cardiologists and radiologists, was formed to propose core competencies fundamental to the expert-level performance of CCT in pediatric acquired and congenital heart disease and adult CHD.

This review will discuss the long-term complications of Kawasaki disease with a particular focus on imaging surveillance of the coronary arteries in adolescence and adult life. The relative advantages and disadvantages of each modality will be illustrated with practical examples, demonstrating that, in many cases, a multimodality imaging strategy may be required.

Cardiac computed tomography (CCT) has increasingly been used in the assessment of both children and adults with congenital heart disease (CHD), in part due to advances in CCT technology and an increased prevalence of adults with palliated CHD. It serves as a complimentary modality to echocardiography, cardiac magnetic resonance imaging and cardiac catheterization. CCT can provide unique diagnostic information, is less invasive and less likely to require sedation compared to other modalities.

Background: Patients with single ventricle (SV) congenital heart disease (CHD) undergo several interventions in the first years of life. Advanced diagnostics are required for interstage assessment of anatomy, but are associated with significant diagnostic risk. We sought to evaluate image quality, risk, and accuracy of cardiac computed tomography (CCT) for evaluation of anatomy prior to superior cavopulmonary connection (SCPC) compared to surgical findings across 2 institutions.

Single ventricle patients typically undergo some form of advanced diagnostic imaging prior to superior cavopulmonary connection (SCPC). We sought to evaluate variability of diagnostic practice and associated comprehensive risk. A retrospective evaluation across 4 institutions was performed (1/1/2010-9/30/2016) comparing the primary modalities of cardiac catheterization (CC), cardiac magnetic resonance (CMR), and cardiac computed tomography (CT).

Background: Image quality and radiation dose are optimized with a slow, steady heart rate (HR) when imaging the coronary arteries during cardiac computed tomography angiography (CCTA). The safety, efficacy, and protocol for HR reduction with beta blocker medication is not well described in a pediatric patient population.

Objective: Provide a safe and efficient metoprolol dose protocol to be used in pediatric outpatients undergoing CCTA.

Background: The objective of this study is to describe the recent trends and in-hospital outcomes with percutaneous pulmonic valve implantation (PPVI) and surgical pulmonic valve replacement (SPVR) in adult hospitals in the US after the availability of both the Melody valve (Medtronic Inc., Minneapolis, Minnesota) and the Sapien XT valve (Edwards Lifesciences, Irvine, CA).

Methods: We queried the National Inpatient Sample database (NIS) from January 2016 to December 2017 to identify hospitalizations for PPVI and SPVR.

The American College of Cardiology (ACC) collaborated with the American Heart Association, American Society of Echocardiography, Heart Rhythm Society, International Society for Adult Congenital Heart Disease, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and the Society of Pediatric Echocardiography to develop Appropriate Use Criteria (AUC) for multimodality imaging during the follow-up care of patients with congenital heart disease (CHD). This is the first AUC to address cardiac imaging in adult and pediatric patients with established CHD. A number of common patient scenarios (also termed "indications") and associated assumptions and definitions were developed using guidelines, clinical trial data, and expert opinion in the field of CHD.

The impact of the coronavirus disease (COVID-19) pandemic in the United States and around the world has required significant changes to medical practice. Amidst the rapidly evolving public health emergency, hospital centers have been required to postpone elective procedures, preserve personal protective equipment (PPE), practice social distancing and limit staff exposures. Patients with congenital heart disease (CHD) often need urgent evaluation, most commonly for preprocedural evaluation.
