Quantitative flow ratio (QFR) allows for the functional assessment of stenosis on par with fractional flow reserve (FFR) but doesn’t require a guidewire, an international group of researchers reported in the Journal of the American Heart Association.

Patients with stable coronary artery disease (CAD) who were evaluated with either cardiac magnetic resonance (CMR) or conventional angiography showed similar rates of myocardial infarction and death at one and three years of follow-up, according to a study published in JACC: Cardiovascular Imaging.

Hybrid imaging with coronary CT angiography (CCTA) and single photon emission CT (SPECT) can provide powerful prognostic value for patients being evaluated for coronary artery disease, according to a single-center study published online July 3 in Radiology.

Two neurologists from Stanford University believe their specialty must take the lead on ensuring patients with cardiovascular implantable electronic devices (CIEDs) have access to MRI when necessary.

UnitedHealthcare (UHC) will now cover the HeartFlow FFRct Analysis, a noninvasive technology that allows clinicians to view a simulated, three-dimensional model of a patient’s coronary blood flow.

A novel positron emission tomography (PET) radiotracer could improve upon current methods for identifying bacterial heart infections, according to a presentation at the annual meeting of the Society of Nuclear Medicine and Molecular Imaging in Philadelphia.

Coronary artery bypass graft (CABG) surgery guided by fractional flow reserve (FFR) significantly reduced the incidence of death or myocardial infarction when compared to angiography-guided CABG, according to an observational study with an average follow-up of seven years.

A deep-learning algorithm can automatically calculate left ventricular ejection fraction (LVEF) with less variability than cardiologists, according to a study presented June 25 at the American Society of Echocardiography’s annual scientific sessions.

The incidence of abdominal aortic aneurysm (AAA) has dropped by more than 70 percent in the past few decades, ultimately shifting the benefit-to-harm balance of screening for the disease, researchers wrote in The Lancet.

The “often overlooked” strategy of stress echocardiography outperformed coronary CT angiography (CTA) in a randomized trial of low to intermediate-risk patients with acute chest pain, resulting in fewer hospitalizations, shorter stays and similar midrange safety outcomes.

Machine learning models using echocardiographic data and variables from the electronic health record (EHR) can significantly improve mortality predictions compared to traditional risk scores, researchers reported in JACC: Cardiovascular Imaging.

A noninvasive imaging technique combined with fractional flow reserve (FFR) showed the potential to detect functionally significant lesions in patients with multivessel coronary artery disease (CAD), according to a study published June 11 in the Journal of the American College of Cardiology.
