 - Structural Heart, severe aortic stenosis, heart valve

The radiotracer 18F-sodium fluoride (18F-NaF) serves as a biomarker of calcification activity in patients with aortic stenosis and may predict disease progression, according to a study published in the March issue of Circulation: Cardiovascular Imaging.

 - brain, stroke

Fragmented care may increase the likelihood of Medicare beneficiaries receiving four or more CT head scans within a year of an ischemic stroke, according to a study that found regional and racial variability in high-intensity CT use.

 - heart, cardiology, cardiac

Few asymptomatic patients with acute coronary syndrome who undergo PCI followed by stress imaging may actually need revascularization, raising questions about the benefits of stress imaging, a study published online March 31 in Circulation: Cardiovascular Imaging found.


 - coronary angiography, cardiovascular imaging, cardiac

Patients should not undergo stress testing after PCI unless there is a clinical indication for this procedure, the Society for Cardiovascular Angiography and Interventions (SCAI) recommends. SCAI issued a list of procedures that should be avoided in patients with or at risk for cardiovascular disease.

 - Regadenoson Ru-82 PET/CT MPI

The use of myocardial perfusion imaging (MPI) has declined over the past few years, researchers wrote in a letter published March 26 in JAMA. The decrease, they explained, could be due to changing physician behavior as well as a lower incidence of coronary disease.

A tool that uses early computed tomography (CT) to quantify brain ischemia may effectively predict reperfusion and outcome in patients who suffer acute ischemic strokes, according to a study published online Dec. 12 in Stroke.

Pocket-size echo a practical, reliable diagnostic tool

The use of pocket-size echocardiography at a patient’s bedside can provide reliable diagnostic information, even if medical residents who perform the tests have limited ultrasound experience. In a study published in the December issue of European Heart Journal – Cardiovascular Imaging, researchers found that with three months of training, residents could obtain valuable information in less than six minutes.

Echo with contrast safer than without in critically ill patients

Although prior research has suggested a higher mortality risk in critically ill patients with the use of an ultrasound contrast agent (UCA) during echocardiography, a study published online Nov. 27 in the Journal of the American College of Cardiology: Cardiovascular Imaging found that UCA actually may be safer than no contrast at all.

Panel outlines optimal use for IVUS, OCT & FFR

Clinicians should not rely on measurements obtained by intravascular ultrasound (IVUS) to evaluate the seriousness of non-left main coronary artery lesions without functional evidence to back them up, experts recommended in a consensus document published online Nov. 13 in Catheterization and Cardiovascular Interventions. This recommendation was one of several made for the optimal use of IVUS, optical coherence tomography (OCT) and fractional flow reserve (FFR).
