ISCT: Machine-learning FFR-CT expedites heart evaluation

By Abraham Kim

Machine-learning fractional flow reserve CT (FFR-CT) may help clinicians overcome key barriers to conventional FFR-CT, including the lengthy amount of time required to obtain measurements, according to a presentation at the 2018 International Society for Computed Tomography (ISCT) symposium.

Delayed NaF-PET enhances coronary plaque detection

By Wayne Forrest

In life, timing is everything. With sodium fluoride (NaF) PET, interpreting results three hours after tracer injection instead of the customary one-hour delay improved image quality and standardized uptake values, leading to significantly better coronary plaque detection, according to a September  13 article in the Journal of Nuclear Medicine.

Notifying cath labs early improves treatment speed, outcome

By AuntMinnie.com staff writers

Informing cardiac catheterization labs of incoming heart attack patients 10 or more minutes before they arrived at the lab reduced their risk of mortality and the time it took for them to undergo surgery, according to research published in the September 24 issue of JACC: Cardiovascular Interventions.

3D virtual heart helps pinpoint irregular heartbeat

By Abraham Kim

Researchers from Johns Hopkins University used a proprietary 3D virtual heart simulator to preoperatively identify areas of cardiac tissue that required surgical treatment for an irregular heartbeat, according to an article recently published in Nature Biomedical Engineering. The method may improve cardiac ablation procedures.

Is Medicare paying enough for MRI-compatible implants?

By Wayne Forrest

U.S. hospitals could be losing up to $400 million annually on placing MRI-compatible cardiac rhythm management devices in patients due to a discrepancy between what the devices cost and what Medicare is paying for them, according to a new report by group purchasing organization Vizient.

Imaging modalities differ in assessing key heart metric

By Wayne Forrest

There is "substantial variability" in the way that different medical imaging modalities measure left ventricular ejection fraction, a key measure of heart function. This variation should be seriously considered before patient treatment, according to an international study published online August 31 in JAMA Network Open.

5 reasons why CCTA should be a first-line test for CAD

By Abraham Kim

Mounting evidence suggests that coronary CT angiography (CCTA) may be the best first-line test for evaluating possible coronary artery disease (CAD). Physicians from Virginia and Texas detailed five features of CCTA that support this idea in an article published online August 28 in the Journal of Thoracic Imaging.

New protocol enables faster, cheaper cardiac MRI scans

By Wayne Forrest

Researchers have developed a rapid contrast-enhanced cardiac MRI protocol that can measure structure, function, and scarring in the heart in less than 20 minutes and at considerably lower cost than standard MRI protocols, according to results published on August 29 in the Journal of the American Heart Association.
