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.

$Performing CT-derived fractional flow reserve (CT-FFR) before transcatheter aortic valve replacement (TAVR) improves the accuracy of coronary CT angiography (CCTA) and helps limit unneeded invasive coronary angiography (ICA), according to a new study published in JACC: Cardiovascular Interventions.

AI-based CAD assessments dramatically improve vascular surgery outcomes
PAD patients evaluated with HeartFlow's noninvasive FFR_CTAnalysis technology prior to surgery experienced much better outcomes, including a 63% lower risk of all-cause mortality after five years.
AI helps cardiologists track new drug's effect on inflammation
The combination of AI and CT helped Nehal Mehta, MD, and colleagues track the performance of a new drug designed to target coronary inflammation.
AI improves CT assessments, boosts care for real-world heart patients
Automated AI-generated measurements combined with annotated CT images can improve treatment planning and help referring physicians and patients better understand their disease, explained Sarah Jane Rinehart, MD, director of cardiac imaging with Charleston Area Medical Center.
AI predicts cardiovascular risk during CT scans—no invasive tests or contrast required
Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans.
CT procedure shown to reduce need for invasive cardiac testing
In a study, CT-FFR was shown to reduce the need for invasive tests to measure coronary artery blockage from 74.5% to 25.5%.

As the population of patients with adult congenital heart disease grows, they are presenting to adult cardiology clinics and being imaged with CT. Many also do not have access or cannot be imaged by MRI, said Renee Bullock-Palmer, MD.

New recommendations for cardiac CT in cardio-oncology imaging

The statement was written to fill gaps in recommendations from prior consensus statements and guidelines in regards to the use of CCT in cardio-oncology, including use of calcium scoring and ruling out coronary disease when cardiac function is impaired.

Coronary CT Angiography (CCTA) has evolved into a much more helpful resource than interventional cardiologists may have originally believed. In fact, the Society of Cardiovascular Computed Tomography (SCCT) emphasized in a new expert consensus statement that CCTA provides specialists with an effective tool in the preparation and optimization of coronary procedures. The 2021 chest pain guidelines elevated CTA to a class 1A recommendation. Harold Litt , MD, explains the use of CCTA in the ED.

CCTA a helpful tool for interventional cardiologists planning coronary procedures

A new consensus statement from the Society of Cardiovascular Computed Tomography emphasized the increasing importance of CCTA among interventional cardiologists. It is no longer seen as “a mere diagnostic tool," the group observed.
