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.

Mitral annular calcium (MAC) does not appear to have a negative effect on long-term transcatheter aortic valve replacement (TAVR) outcomes, according to new research published in the American Journal of Cardiology.

TAVR safe and effective for patients presenting with mitral annular calcium

Researchers from Cleveland Clinic reviewed data from more than 400 patients, presenting their findings in the American Journal of Cardiology.

CT coronary artery calcium (CAC) scoring, also known as the Agatston score, to assess the risk a patient has for future heart attacks and help decide if a patient requires statins.

Mike Shapiro, DO, MD, director of the Center for Prevention of Cardiovascular Disease at Wake Forest University, discusses the current guidelines for computed tomography (CT) calcium scoring as a screening test to assess heart attack risk.

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).

VIDEO: Why plaque composition CT imaging may be the future of cardiology

Former European Society of Cardiology president Prof. Jeroen Bax explains the difficulty in quantifying these plaques manually and how artificial intelligence may change this to allow rapid, detailed quantitative analysis.

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.
