Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

Novel imaging approach IDs CAD without the risk of a contrast agent

Researchers at Beth Israel Deaconess Medical Center in Boston have developed an imaging technique that allows physicians to diagnose CAD without the risk of a contrast agent.

The economic impact of MR on heart failure patients

Newly diagnosed HF patients with concomitant mitral regurgitation can expect more admissions, longer hospital stays and pricier medical bills than HF patients without MR, according to an analysis published in the American Journal of Cardiology.

How researchers are using patient selfies to monitor blood pressure

A study published this week in Circulation: Cardiovascular Imaging details how one Canadian scientist and his team are using 2-minute video selfies to track patients’ blood pressure.

Researchers 3D-print heart components using collagen

Researchers at Carnegie Mellon University’s College of Engineering have devised a way to 3D bioprint tissue scaffolds out of collagen, putting them one step closer to the goal of printing a full-sized, functional human heart.

Are patients undergoing unnecessary gated calcium CT imaging?

“Knowledge of CAC on a prior chest CT may eliminate the need for a subsequent dedicated gated calcium score CT, leading to earlier diagnosis and management of cardiovascular disease as well as decreasing radiation exposure and health care costs,” wrote authors of a recent study.

CT CAC associated with long-term mortality in young adults

A high coronary artery calcium (CAC) score was linked to an increased risk for cardiovascular disease (CVD) and mortality in patients between 30 and 49 years old, researchers of a new study published in JAMA Network Open found.

Chemicals in plastic medical devices could interfere with cardiac electrophysiology

Heart patients exposed to phthalates—a group of chemicals used as plasticizers in the manufacture of plastic medical products—during invasive procedures may be at risk for serious electrophysiological abnormalities, according to a new study.
