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.

Cleerly’s AI software for noninvasive FFR estimates receives a Category 1 CPT code

The company officially launched its Cleerly ISCHEMIA software for delivering noninvasive evaluations of CCTA exams in early 2024. This update provides a closer look at the software from a billing perspective. 

Examples of photon-counting coronary angiography showing how clarity improves as the thickness of the image is reduced. Top: 60-year-old female, with noncalcified plaque (arrowheads) and coronary stenosis (inset images). The reduced section thickness did not affect assessment in this patient. Bottom: 56-year-old female with calcified plaque (arrowheads) and coronary stenosis. The reduced section thickness leads to less calcium blooming and therefore a less severe percentage of stenosis.

Coronary artery disease classification improved with photon-counting CT

After a photon-counting CT, 54% of patients had their coronary artery disease classification downgraded.

CT-first strategy the most effective path forward when evaluating stable chest pain

Heart teams have several options when patients present with stable chest pain and require further testing. According to a brand new analysis of nearly 800 patients, CCTA may be the best place to start.
