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.

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.

Examples of the messages the Nanox AI algorithms display for incidental findings of spinal compression fractures and detection of coronary calcium. Both can help physicians better understand risk factors or need for therapy in patients through these types of opportunistic screenings on scans being performed for other reasons.

Routine chest CT often reveals patients at risk for cardiovascular disease, presenting radiology with ‘untapped’ potential

Rads only reported this incidental finding in about 31% to 44% of cases, experts detailed in the Journal of the American College of Radiology

Michael Garshick, MD, director of the cardio-rheumatology program, cardiologist and assistant professor, Ronald O. Perelman Department of Dermatology, NYU Grossman School of Medicine, explains the role of inflammation in coronary disease development and how this risk factor can be detected and treated.

AI cardiology heart artificial intelligence deep learning

AI could be a game-changer for TAVR, but cardiologists remain ‘irreplaceable’

The rise of TAVR as a go-to treatment option for many AS patients has been one of the biggest stories in cardiology for several years now. How will advanced AI models impact this trend going forward? 

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. 

HeartFlow’s AI-powered CAD offering receives new CPT code with improved reimbursement rate

For this update to be finalized, the American Medical Association had to determine FFRCT Analysis met certain requirements in terms of its overall impact on patient care. John Farquhar, CEO of HeartFlow, described the news as "a win for everyone involved, most notably patients." 

Professor Keith Channon, MD, MB ChB, FRCP, interventional cardiologist and the British Heart Foundation Professor Cardiovascular Medicine at the University of Oxford, and a co-founder of Caristo, explained an AHA 2023 study where AI identified coronary inflammation as a major silent risk factor and a strong predictor of heart attack risk.

AI model targets inflammation, helping cardiologists find 'invisible' heart patients

By focusing more on inflammation, cardiologists can ensure they are identifying patients who need help before it's too late.

TAVR after mitral valve replacement

TAVR after mitral valve replacement linked to positive outcomes, but heart teams must plan ahead

Researchers in India performed TAVR on two relatively young patients with a preexisting mechanical mitral valve, sharing their experience in a new case report. The group highlighted the importance of planning ahead.
