Patients who received aortic valve repair or replacement (AVR) based on Class II indications fared better than those who underwent surgery for Class I triggers in a single-center study, suggesting earlier intervention may be warranted in asymptomatic individuals with chronic aortic regurgitation.

Using MRI scans to measure iron content can help specialists learn more about stroke-related damage to the brain, according to a new study published by Radiology. Should such measurements be required after patients suffer a stroke?

Radiologists commonly overlook potentially important information about a patient’s heart health when they’re performing mammograms or CT scans before starting cancer treatment, according to research set to be presented at the American College of Cardiology’s scientific sessions March 16-18 in New Orleans.

A new analysis from the PROMISE trial suggests CT angiography (CTA) may be a superior front-line diagnostic test for patients with diabetes and symptoms suggestive of coronary artery disease (CAD).

T2 mapping derived from weekly cardiac MRIs helped researchers identify cardiotoxicity at an early and reversible stage, a finding which may have implications for cancer patients at risk of chemotherapy-induced heart failure.

The Department of Energy’s National Nuclear Security Administration (NNSA) will negotiate with four U.S. companies to potentially fund molybdenum-99 (Mo-99) production without the use of highly enriched uranium.

By modifying the appropriate use criteria (AUC) for transthoracic echocardiograms (TTEs) and educating physicians on which tests should be performed in an inpatient versus outpatient setting, researchers at Bridgeport Hospital in Connecticut reduced their inpatient echo order volume by 11.1 percent and boosted the efficiency of their department.

Cardiac MRI (CMR) is rarely performed in conjunction with stress testing of heart patients—nuclear perfusion and echocardiography are far more common imaging aids—but a large new study may begin to turn the tide toward magnets as an eventual first-line diagnostic option.

A new, noninvasive technique for imaging the carotid artery can offer insight into plaque characteristics in real time, leading one researcher to suggest the modality could become as popular as ultrasound.

“Rather than bringing in many additional statin candidates, this testing should serve as a decision aid to ‘de-risk’ certain patients and distinguish those who may benefit from preventive pharmacologic therapies," Johns Hopkins researchers wrote in the Annals of Internal Medicine.

A four-stage system that quantifies the extent of cardiac changes associated with aortic stenosis was linked to the odds of death and readmission following transcatheter aortic valve replacement (TAVR), a finding that may aid cardiologists in making prognoses and engaging in shared decision-making with patients.

Biologic treatment favorably modifies coronary plaque characteristics for patients with severe psoriasis, suggests a study published Feb. 5 in Cardiovascular Research. The findings raise the possibility that the anti-inflammatory drugs can both treat psoriasis and reduce cardiovascular risk.
