Computed Tomography

Cardiac computed tomography (CT) has become a primary cardiovascular imaging modality in the past 20 years, and was recommended as a 1A recommendation in the 2021 chest pain assessment guidelines. CT calcium scoring has became a primary risk assessment for coronary artery disease and whether patients should be on statins. Coronary CT angiography (CCTA) is used to for anatomical assessment of the arteries for plaque burden and to identify areas of blockage that may cause ischemia and heart attacks. Additional use of contrast CT perfusion or fractional flow reserve CT (FFR-CT) can offer physiological information on the function of the heart. CT plays a primary role in structural heart assessments for heart valves, repair of congenital defects and left atrial appendage occlusion (LAAO) for both pre-procedure planning and procedural guidance.

VIDEO: CT imaging to plan coronary interventions — Interview with Jonathon Leipsic, MD

Jonathon Leipsic, MD, chairman of the Department of Radiology, University of British Columbia, explains how noninvasive computed tomography angiography (CTA) can be used to aid in planning interventional cardiology procedures for percutaneous coronary intervention (PCI) and chronic total occlusions (CTO).

Cardiac CT soft plaque assessment may offer paradigm shift for coronary disease screening

New artificial intelligence software that can evaluate coronary CT scans to automatically assess soft plaques were by far the biggest technology advance discussed at the Society of Cardiovascular Computed Tomography (SCCT) 2022 meeting.

TricValve Transcatheter Bicaval Valves System P+F Products + Features GmbH

TricValve device proven safe and effective after 6 months for patients with severe symptomatic TR

The study's authors explored data from 35 patients who received the TricValve Transcatheter Bicaval Valves System. All patients presented with severe tricuspid regurgitation.

The ASNC is one of several medical imaging societies asking Congress to repeal the appropriate use criteria (AUC) criteria mandate. They say it poses issues for clinicians and is becoming outdated by changes in CMS payment systems. The AUC requirements call for documentation using CVMS authorized software in order to show advanced imaging such as nuclear and CT is justified, or else Medicare payments might be withheld.

VIDEO: AMA will ask Congress to revise clinical decision support mandate for cardiac imaging

American Society of Nuclear Cardiology (ASNC) delegates to the American Medical Association (AMA) House of Delegates 2022 meeting Stephen Bloom, MD, and Nishant Shah, MD, explain a new AMA policy asking Congress to revise its clinician decision support mandate.
