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.

Researchers question FFR-CT’s value compared to other cardiac imaging options

FFR-CT has grown in popularity due its ability to provide noninvasive evaluations of patients being considered for revascularization procedures. According to a new study in JACC: Cardiovascular Imaging, however, stress imaging strategies may still provide more value in certain scenarios. 

To hear about key trends in cardiac imaging, Cardiovascular Business spoke with two experts in cardiac imaging at American College of Cardiology (ACC) 2023 meeting, Marcelo DiCarli, MD, chief, division of nuclear medicine and molecular imaging, executive director for the cardiovascular imaging program, Brigham and Women's Hospital, and Rob Beanlands, MD, is director of the National Cardiac PET Centre at the University of Ottawa Heart Institute, Canada.

What's new in cardiac imaging? 2 experts discuss the latest trends

Marcelo DiCarli, MD, and Rob Beanlands, MD, shared their thoughts on the current state of cardiac imaging at ACC.23. 

Cardiologist Martha Gulati, MD, who specializes in both preventive cardiology and cardiovascular disease in women, has been named the Anita Dann Friedman Endowed Chair in Women’s Cardiovascular Medicine and Research at Cedars-Sinai in Los Angeles.

Gulati, known for her work in the field of preventive cardiology, is also being recognized for her role in the development of the 2021 chest pain guidelines.

HeartFlow announces US launch of AI-powered solution for evaluating coronary arteries

The AI-powered tool gained FDA clearance back in October 2022. 

HeartFlow raises $215M to keep up with growing demand

The company is still riding the momentum of its technology being included in the 2021 American College of Cardiology/American Heart Association chest pain guidelines.

Example of an FFR-angio image-derived hemodynamic flow model performed tableside in the cath lab reconstructed using three different C-arm contract image acquisitions. This technology from CathWorks, which was recently acquired by Medtronic, can eliminate the need for pressure wires and adenosine to assess FFR pressures. These measurements are used to determine the hemodynamic significance of a stenosis and determine if a stent is necessary or if a patient can be treated medically.

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.
