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.

Ed Nicol, MD, consultant cardiologist and honorary senior clinical lecturer with Kings College London and president-elect of the Society of Cardiovascular Computed Tomography (SCCT), explained artificial intelligence (AI) in cardiac CT is here to stay and its use is expanding. He noted that one AI-based algorithm is already included in recent cardiology guidelines and more will likely follow. #SCCT

Cardiac imagers need to understand AI as it enters clinical use and ACC guidelines

Most FDA-cleared AI algorithms are related to radiology and cardiology, meaning radiologists and cardiologists need to make an effort to learn how these technologies work.

The remaining gaps in evidence for cardiac CT

While the ACC/AHA 2021 Chest Pain Assessment Guidelines included cardiac CT angiography as a top level recommendation, gaps in evidence still need to be filled.

‘Revolutionary’ new CT scans identify the most common cause of high blood pressure

Primary aldosteronism (PA) is one the single most common causes of hypertension, but identifying patients with PA—and knowing which ones may benefit from a surgical treatment—can be quite challenging.

FDA makes clearance easier for cardiac device implant simulation software

The FDA is reclassifying interventional cardiovascular implant simulation software into the class II (special controls) regulatory category, which will make it easier for the technology to pass regulatory approval.
