Optical coherence tomography (OCT) can detect coronary vascular changes beyond the capabilities of angiography in pediatric heart transplant recipients, according to a study published July 18 in JACC: Cardiovascular Imaging.

Twice as many U.S. deaths due to cardiac amyloidosis were reported in 2015 than in 1979, but a study in JAMA Cardiology suggests the disease remains vastly underdiagnosed.

A quantification of myocardial blood flow using CT perfusion (CTP) imaging was strongly predictive of major adverse cardiac events (MACE) and offered additional prognostic ability when added to coronary CT angiography, researchers reported in JACC: Cardiovascular Imaging.

Interest in Tc 99m PYP is growing as new therapies for cardiac amyloidosis show promise in late-stage clinical trials.

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.
