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.

Early results find fused fluoro/echo imaging system effective in kids with CHD

Researchers from Children’s Hospital Colorado have had success using a fused fluoroscopic and echocardiographic imaging system in children with congenital heart disease, a patient population that typically has not used the system.

SNMMI: Scanning for cardiac amyloid could help predict heart attacks

While amyloid imaging is typically discussed with regard to diagnosing Alzheimer’s disease, a team of French researchers, presenting at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2015 annual meeting, have found that amyloid scans of the heart can predict major cardiac events.

CCTA’s insights on plaque may help track treatment response

Coronary CT angiography (CCTA) may allow cardiologists to assess the progression or regression of plaque in asymptomatic patients at low to moderate risk who are treated with statins, according to a study published in Radiology on June 2. The study also shed light on predictors of noncalcified plaque.

Imaging change cuts radiation exposure during TAVR procedures

Operators performing transcatheter aortic valve replacement (TAVR) procedures reduced radiation dose by 27 percent by modifying imaging settings. Using a lower setting didn’t affect screening time, procedure time, contrast use or procedural outcomes.

Thoratec receives conditional FDA approval for the Shield II U.S. clinical trial for HeartMate PHP

Thoratec Corporation, a world leader in mechanical circulatory support therapies to save, support and restore failing hearts, announced that the FDA has granted conditional approval for a U.S. IDE clinical trial to investigate use of the HeartMate PHP acute catheter-based heart pump in patients undergoing a high-risk percutaneous coronary intervention.

Endovascular treatment trials underscore CT imaging’s value

Several late-breaking clinical trials at the 2015 American Stroke Association conference raised hope that device-based endovascular treatment improved outcomes in patients with ischemic stroke. For imagers, the results also raised questions about their role going forward.

Drinking alcohol may contribute to heart problems for older adults

Older adults who drank two or more alcoholic beverages each day had changes in cardiac structure and function, according to a large, community-based study. Results were published online in Circulation: Cardiovascular Imaging on May 26.
