Key COVID-19 Guidance Documents that Provide Recommendations on use of Cardiac CT.

Publication	Year	Objective/Scope	Summary/Selected recommendations related to CCT
Use of Cardiac Computed Tomography Amidst the COVID-19 Pandemic – SCCT Guidance Document Endorsed by ACC8	Choi et al. JCCT 2020 Living document: https://scct.org/page/COVID-19	Guidance document for cardiac CT practitioners.	•Basic concepts relating to safety. •Cardiac CT indications and timing. •Role of coronary CTA for evaluating patients with myocardial injury versus possible ACS in known or suspected COVID-19. •Incidental pulmonary findings. •Considerations for pediatric imaging and evaluation of congenital heart disease.
Safe Reintroduction of Cardiovascular Services During the COVID-19 Pandemic: From the North American Society Leadership2	Wood et al. JACC 2020	Guidance on the safe reintroduction of invasive CV procedures and diagnostic tests after the initial peak of the COVID-19 pandemic.	•Advice on timing of reintroduction of various CT services.
Multimodality Cardiovascular Imaging in the Midst of the COVID-19 Pandemic Ramping Up Safely to a New Normal1	Zoghbi et al., JACC CV Imaging 2020	Expert opinion from the editors of JACC: Cardiovascular Imaging and developed in collaboration with the Cardiovascular Imaging Council of the American College of Cardiology.	•Coronary CTA may be useful in selected patients who have elevated cardiac enzymes, inconclusive electrocardiogram, and symptoms of possible acute coronary syndrome in order to exclude obstructive CAD. •Evaluation of patients with no known CAD presenting with symptoms of possible angina. •Identifying patients with CAD who can be treated conservatively (e.g., by excluding high-risk anatomy or through the use of CT–fractional flow reserve).
Multimodality Imaging in Evaluation of Cardiovascular Complications in Patients With COVID-1940	Rudski et al. JACC 2020	Expert Panel from the ACC Cardiovascular Imaging Leadership Council.	•Provides patient centered algorithms for 4 different clinical scenarios. •“In patients with chest pain and ST-segment elevation without clear evidence of STEMI, coronary CTA is preferred as an initial advanced imaging study in order to rule out ACS.” •“Coronary CTA is particularly useful in patients without previously established CAD or severe coronary artery calcification.”
Management of Acute Myocardial Infarction During the COVID-19 Pandemic13	Mahmud et al., JACC 2020	Consensus statement from SCAI, ACC, and ACEP for care of patients with acute MI.	•Selective role of coronary CTA in STEMI: “Coronary CT angiography may be considered in cases where the findings of ST elevation and transthoracic echocardiography are divergent.”
ESC Guidance for the Diagnosis and Management of CV Disease during the COVID-19 Pandemic25	Online at: https://www.escardio.org/Education/COVID-19-and-Cardiology/ESCCOVID-19-Guidance (Last update: June 10, 2020)	A guidance document relevant for all aspects of CV care during the COVID-19 pandemic.	•“Coronary CTA may be the preferred non-invasive imaging modality to diagnose CAD since it reduces the time of exposure of patients and personnel.” •“Cardiac CT is preferred to TEE to rule out the presence of intracardiac thrombus.” •“In patients with acute chest pain and suspected obstructive CAD, coronary CTA is the preferred non-invasive imaging modality since it is accurate, fast and minimizes the exposure of patients.” •Stable NSTEMI patients: “Non-invasive imaging using coronary CTA may speed-up risk stratification, avoid an invasive approach allowing early discharge.” •Myocarditis: “Coronary CTA should be the preferred approach to rule out concomitant CAD.”
